Hydrogen peroxide can be used alone to bleach hair, but in hairdressing salons it is mixed with an alkaline solution, typically ammonia, before use, in order to accelerate the process.

Persulfates are often used in the formulation of bleaching powders that are mixed with hydrogen peroxide just before use, particularly as the sodium, potassium and ammonium salts; sodium percarbonate is used occasionally, diluted in water or hydrogen peroxide just before use; sodium perborate and magnesium perborate are rarely used; and magnesium dioxide and barium dioxide are sometimes present in bleaching powders.

Bleaching formulations are available in several forms: hydrogen peroxide solutions and emulsions, creams, shampoos, powders, pastes and oils Zviak, a. In order to remove permanent and semi-permanent hair colourings, hairdressers use reducing agents sodium hydrosulfite or sodium or zinc formaldehyde sulfoxylate dissolved just before use in acidified water or high-strength oxidants such as those mentioned above Zviak, a.

About one-third is bought by salon owners and the remainder by retail outlets for home use. The types of hair colourants are classified according to the permanence of the effect, i. Only permanent and semi-permanent hair colourants are used to a significant extent in the hairdressing trade, whereas all three classes are used extensively by consumers. In Japan and parts of Asia, permanent dyes comprise an even greater share of the market.

Semi-permanent dyes were introduced into Europe about 40 years ago and into the USA some 35 years ago. Permanent dyes Zviak, c : Permanent hair dyes, otherwise known as oxidation dyes, represent the major segment of the hair dye market. The hair is dyed by oxidation of dye precursors which penetrate the hair fibre, where they react with hydrogen peroxide to produce coloured indo dyes. Since hydrogen peroxide is an excellent decolorizing agent for melanin, the hair's natural colouring matter, manufacturers can balance the amounts of hydrogen peroxide and of dye precursors in such a way as to produce lightening, darkening or matching of the natural colour of the hair.

Compounds used as couplers include resorcinol, meta -aminophenol, meta -phenylenediamine and certain other reactive intermediates such as 1-naphthol and phenylmethylpyrazolone.

Permanent hair colouring preparations may contain as many as 15 different dyes and dye precursors so that they will produce the desired shade. Dye precursors are formulated in ammoniacal or detergent solutions. Two typical formulations of permanent hair colours are presented in Table 2and oxidation dye precursors used in the USA and Europe are listed in Table 3. Major oxidation dye precursors used in the USA and Europe.

Most of the more important ingredients in permanent dyes have been in use for over produit minceur modere prix years, although a few new ones were introduced during the last 20 years.

The use of some ingredients has been discontinued, usually simultaneously in North America, Europe and Japan, as a result of findings in assays of carcinogenicity in rodents. For example, use of 2,4-diaminotoluene 4-methyl- meta -phenylenediamine was discontinued in —71 and that of 2,4-diaminoanisole 4-methoxy- meta -phenylenediamine some six years later.

For other reasons, para -phenylenediamine was not used in France or Germany from about to —85, during which time 2,5-diaminotoluene 2-methyl- para -phenylenediamine was used in its place. About g of this mixture containing 0. During that time, the colour develops and the natural hair pigment is lightened. The residual product is then removed from the hair by rinsing.

Benefits of Purple Shampoo for Hair Health #Beauty Tricks

Permanent colouring materials occur in a number of different forms: liquids, creams, gels, shampoos and powders. Liquid dyes have been replaced by cream- or gel-based formulae. Cream dyes are emulsions formed from self-emulsifying raw materials, such as fatty oxyethyleneated alcohols partially sulfated or notfatty amides and oxyethylated vegetable oils.

Emollients such as lanolin derivatives, fatty alcohols and cation-active compounds may be added. Gel dyes or, more properly, gelling dyes offer the advantages of both liquids and creams.

A number of formulations exist, but the following are typical: i soap solutions, generally ammonium oleate; ii solutions of low oxyethylated nonionic surfactants, most often polyoxyethylated alkylphenols; and iii anion-cation complexes in solution. These materials colour and bleach less than other permanent dye products. Powder dyes contain very stable oxidizing agents, such as sodium perborate, in powder form, and only non-lightening shades can be formulated.

Owing to the rate of hair growth about 1. Permanent hair colouring products are therefore used about six to nine times per year in Europe and North America. Measurements of skin penetration of some oxidation dye precursors are discussed in section 4.

That level of wash fastness is achieved by using low-molecular-weight dyes capable of penetrating the hair cortex. Semi-permanent hair colours contain direct dyes, which are generally nitro derivatives of phenylenediamines or aminophenols, together with a selected number of azo dyes and aminoanthraquinone dyes. Because the dyes in semipermanent hair colours are preformed and do not require added oxidant, such products cannot lighten the natural hair colour. Some typical formulations are presented in Table 4 ; semi-permanent dyes used in the USA and Europe are listed in Table 5.

Henna, an orange-red hair colouring derived from the powdered leaves and stems of Lawsonia inermisa tropical shrub, has been used since antiquity and is still used, by both professional hairdressers and consumers Feinland et al. The active colouring matter in henna is 2-hydroxy-1,4-naphthoquinone Farris, Ingredients of typical semi-permanent hair colouring products. The dyes used in semi-permanent colourants have been used for 30 years or less, which is shorter than for permanent dyes, except for a few of the direct dyes that were used as toners in permanent colourants the unsubstituted nitrophenylenediamines and nitroaminophenols.

Use of HC Blue No. Semi-permanent colouring products come in several forms. Colour rinses are the simplest means for altering hair colour: The hair is rinsed with a dilute aqueous or aqueous alcoholic dye solution.

The dyes are generally cationic and are adsorbed by the hair surface.

More pronounced colour changes are possible with tints, which are formulated with direct dyes; intense colours can be obtained, especially with nitro dyes. With foam tints, a surfactant solution is dispensed as a foam from an aerosol. Tints can be also thickened with cellulose derivatives, natural mucilage or century bike rides bay area polymers.

Concentrated solutions with intense colouring action can be obtained by using co-solvents e. In emulsion tints, the dye base consists of an emulsion Clausen, Semi-permanent colours are applied at 35—60 g to the hair for 10—30 min, followed by rinsing.

The colouring lotion contains 0. Users either apply secondary caries fluoride varnish products at least monthly or use them only on special occasions, for example, three to four times a year. Measurements of skin penetration of some semi-permanent dyes are discussed in section 4. They are normally formulated with water-soluble acid or basic dyes of the type used in wool dyeing, which have a molecular size too great to penetrate the cortex of the hair.

As a result, the dye is deposited on the surface, from which it is easily removed by washing. Temporary colourants may also comprise systems which produce insoluble complexes of an acid dye as a quaternary ammonium or metal salt. A commercial dye formulation may contain between 0.

Temporary dye formulations may also contain nitro aromatics as colourants, together with anionic detergents and urea to increase the solubility. Temporary colourants are occasionally used in the hair-dressing trade but are more commonly used directly by consumers at home.

While there are few data on skin absorption, very little of such materials will pass through the skin owing to the relatively high molecular weight of the dyes. Virtually no metal salt e. Furthermore, the selection of colours available is limited, and the shades look metallic and unnatural. Metal salts are also incompatible with permanent waving and bleaching of hair Clausen, Shampoos are cosmetic products for cleaning the hair and scalp. Shampoos are the cosmetic products most often applied to the hair.

Some of the characteristics considered in formulating modern shampoos are their ability to clean, to lather and to make the hair easy to comb, their capacity to condition the hair, mildness compatibility with skin, eyes and mucosa; no burning on the scalp or in the eyescolour, appearance and fragrance Lang, a.

The principal constituents and most important raw materials of shampoos are surfactants, and nearly all modern shampoos are aqueous surfactant preparations. Surfactants break the bonds between dirt and hair components and suspend the dirt in the aqueous medium Lang, a. Bar soaps were probably used for washing hair from aboutwhen they first became available, until the s and s, when liquid soaps and cream shampoos were introduced.

The first surfactants used for hair cleansing were fat soaps. In hard water, however, soaps create a deposit of calcium and magnesium fatty acid salts on the hair, so their use must be followed by treatment with an organic acid, such as citric or acetic acid. Another drawback is the alkaline pH of soap, which may increase the swelling of hair. In order to meet the requirements of high cleansing power, good lathering and safety for the user and for the environmentmodern shampoos are formulated mainly with anionic surfactants.

Amphoteric surfactants are also used, whereas nonionic and cationic surfactants play only secondary roles in special-purpose formulations Lang, a. The most important anionic surfactants used in shampoos are alkyl sulfates ammonium lauryl sulfatealkyl and alkylaryl sulfonates, olefin sulfonates, secondary alkyl sulfonates, alkyl ether sulfates, sulfosuccinates disodium lauryl ether sulfosuccinate and protein-fatty acid condensates potassium coco-hydrolysed animal protein Lang, a.

Sulfonated oils, such as sulfonated castor, mineral and olive oils, were introduced for use in shampoos in the s; their use continued into the s, with declining popularity. Sulfated fatty alcohols were first introduced in Europe in the s and in the USA late in the s in salon products and some retail products. The trend in the late s was to increase the use of liquid shampoos over that of creams, and there was then a movement to use of ammonium lauryl sulfate, introduced in the early s, and laurylether sulfates.

Laurylether sulfates are the preferred detergents in Europe. Amphoteric surfactants used in shampoos can be divided into two classes: betaines coco-amidopropylbetaine and alkyl amphoglycinates and alkyl amphopropionates coco-amphocarboxyglycinates and coco-amphocarboxypropionates.

Cationic surfactants have a positive charge and are strongly absorbed by the hair. Only a few special-purpose shampoos, especially those for the treatment of severely damaged hair, contain these compounds. The nonionic surfactants in use are polysorbates Polysorbate 20, Polysorbate 80 and fatty alcohol ethoxylates and polyglycerides Lang, a. Another important class of constituents of shampoos is foam builders, typified by the fatty acid mono- and dialkanolamides Lang, a introduced in the late s.

By the mid s, virtually all liquid shampoos based on lauryl sulfates contained alkanolamides. Two types of amides are used. Condensation of 1 mol of fatty acid with 1 mol of an alkanolamine such as diethanolamine gives a water-soluble product; condensation of 1 mol of fatty acid with 2 mol of diethanolamine gives a more water-soluble product.

The types of alkanolamides can have appreciable levels of free alkanolamine, fatty acid amide and free fatty acids.

Some of the commonest examples of these constituents are the amides derived from reaction of diethanolamine with lauric acid and with coconut oil fatty acids Kritchevsky, ; Barker, Other constituents of shampoos include: refatting agents, conditioning additives cationic polymers such as quaternary hydroxyalkyl cellulosesthickeners salts such as sodium and ammonium chloride in combination with amphoteric surfactantsopacifiers fatty acid alkanolamides in mixtures with ethylene glycol monostearate and distearate or cetyl alcohol and stearyl alcoholcolouring agents, fragrances and buffers pH stabilizers, such as citric, tartaric, adipic and phosphoric acids and their salts.

The preservatives added to shampoos today include formaldehyde and its donors and isothiazolinones, introduced in the s. From the s to the mids, the main preservatives were parabens and phenylmercuric acetate Liem,which was banned in the late s Feinland et al.

Shampoos may be clear, opaque or pearly liquids, gels or aerosols. Shampoos with special additives include those for frequent use and for babies, conditioning shampoos, antidandruff preparations, shampoos for oily hair, tinting shampoos and those containing insecticides. Shampoos for frequent use and for babies contain especially mild surfactants e. Conditioning shampoos are used to make the hair easy to comb in the wet state and glossy and soft when dry.

These effects are provided chiefly through the addition of cationic polymers; addition of amphoteric surfactants or refatting agents can improve the conditioning qualities of anionic surfactant formulations.

Antidandruff shampoos contain agents that reduce excessive scalp flaking to a normal level. The most important antidandruff ingredients are zinc pyrithione, Octopirox 1-hydroxymethyl[2,4,4-trimethylpentyl]-2[1 H ]-pyridone and Climbazole Baypival; 1-[4-chloro-phenoxy][1-imidazolyl]-3,3-dimethylbutanone Lang, a. Coal-tar formulations Weinberg, and selenium disulfide have also been used extensively, but their use is regulated in some countries.

Hair can be damaged in a number of ways: by climatic effects such as humidity and temperature extremes weathering ; by exposure to sunlight; by washing with products containing surfactants; by cosmetic treatments, such as bleaching, dyeing, permanent waving and straightening; and by combing and brushing.

These processes alter the physical, chemical and morphological properties of hair as well as its reaction to cosmetic treatments such as dyeing and permanent waving.

They lead to perceptible roughening of the hair surface, difficulty in combing, tangling, increased static charge, formation of split ends and loss of natural lustre. Hair conditioning agents prevent, retard or mask such changes. Their action is restricted largely to modifying the surface qualities of the hair and making it glossy. Nearly all modern shampoos, permanent wave lotions, setting lotions and dyes contain conditioning additives that prevent excessive mechanical damage to the hair.

This simple type of conditioning may not be sufficient for severely damaged or long hair, and special conditioning treatments are available for such cases Lang, a. The earliest conditioning treatments were waxes and oils vegetable and mineral oils, petrolatumwhich provided lubrication and enhanced lustre, and acid rinses lemon juice, vinegarwhich counteracted the undesirable effects of soap shampoos.

During the s and s, these ingredients were combined with surfactants in anionic emulsions as after-shampoo rinses. Alkaline rinses included water-softening ingredients such as borax and trisodium phosphate Wall, In the mids, the quaternary ammonium compound, stearyl dimethyl benzyl ammonium chloride, began to be investigated for use as an after-shampoo treatment.

By the early s, almost all after-shampoo conditioners contained quaternary ammonium compounds as cationic surfactants. Typical quaternary compounds in current use include cetyldimethylammonium chloride and cetyltrimethylammonium chloride, sometimes in formulations with fatty alcohols such as cetylstearyl alcohol or with simethicone Lang, a. Cationic polymers can also be used in conditioning treatments, together with special ingredients such as antidandruff additives.

The addition of special wax components abc rides dallas pearly preparations; if water-insoluble components are omitted and cationic polymers are added, the formulae obtained are transparent and clear. Conditioning treatments are generally rinsed out after they have been allowed to work for a defined time; however, some newer products with a lower content of active ingredients can be left on the hair without rinsing Lang, a.

Styling preparations stabilize a hair-style during or after its creation with comb, brush or rollers, usually as a temporary set. Styling products may also make hair easier to manage, for example, by facilitating wet combing and brushing. The products are mainly setting lotions and hair sprays. Styling preparations are generally left on the hair and are not rinsed out. Their active ingredients are usually dissolved polymers, known as film-forming agents, which are deposited on the hair after evaporation of a solvent Lang, b.

They may be applied before hair is wound on rollers and dried wave sets or before use of a hair dryer, brush or comb to style the hair blow-dry sets Lang, b. The first preparations comparable to modern setting lotions were aqueous or aqueous alcoholic solutions and gels of natural substances, such as egg white, sugar solutions, plant mucilage pectins, alginates, carrageenan, karaya gum, tragacanth and beer.

They had the drawback of forming opaque, brittle residues which created dust during combing or brushing and became sticky in the presence of moisture. Modern setting lotions contain polymers film-forming agentssolvents, agents to facilitate combing, plasticizers, fragrances, colouring agents, ultra-violet radiation stabilizers, preservatives if necessary and other special ingredients Lang, b.

Film-formers are nonionic, anionic or cationic polymers dissolved in water or water-alcohol mixtures. Nonionic film-forming polymers include polyvinylpyrrolidone, the first polymer used for this purpose, and vinylpyrrolidone-vinyl acetate copolymers. Anionic film formers are vinyl acetate-crotonic acid copolymers or copolymers of methyl vinyl ether and maleic acid semi-esters. Both types of polymer are usually neutralized with organic amines such as 2-aminomethyl-l,3-propanediol, 3-aminomethylpropanol or triisopropanol-amine.

Other anionic polymers are terpolymers of vinyl acetate, crotonic acid and vinyl esters and graft polymers of vinyl acetate, crotonic acid and poly ethylene oxide. Cationic polymers have an affinity for keratin, thus making the hair easier to untangle; they also prevent the accumulation of static charge during combing and brushing.

The most important cationic film-forming polymers are quaternary vinylpyrrolidone-dimethylaminoethyl methacrylate copolymers CTFA Polyquaternium 11vinylpyrrolidone-vinylimidazole copolymers CTFA Polyquaternium 16cationic hydroxyethyl cellulose CTFA Polyquaternium 10poly dimethyldiallyIammonium chloride CTFA Polyquaternium 6poly- dimethyl-diallylammonium chloride copolymers CTFA Polyquaternium 7 and chitosan obtained from chitin by alkali treatment or its derivatives Lang, b.

The solvents used in setting lotions are water, ethanol, 2-propanol and their mixtures. Agents that facilitate combing include the cationic film-forming polymers listed above and cationic surfactants such as cetyltrimethylammonium chloride or bromide.

Plasticizers enhance the flexibility of films formed on the hair. They include esters such as diethyl phthalate, diethyl citrate, adipates, silicones and polyglycols Lang, b.

Setting lotions are usually marketed as dilute, aqueous alcoholic solutions in single- or multiple-application packages. Depending on intended use, they contain 0. Setting lotions for waving have a higher polymer content than those for blow-drying.

Gels thickened by the addition of higher-molecular-mass polymers of the poly acrylic acid type are used far less frequently. Liquid lotions can also be packaged as aerosol sprays propellant or pump spray. A novel form is the aerosol foam mousse. Addition of adsorptive or penetrating dyes to setting lotions allows simultaneous hair colouring Lang, b. Aerosol spray-can products first came into widespread use in abouton the basis of technology developed for insecticide applications during the Second World War.

By virtue of the propellant liquid-gas equilibrium in the pressurized can, the pressure remains roughly constant during spraying. The most important ingredients of hair sprays today are concentrates film-forming agents, solvents, plasticizers, agents for lustre and fragrances and propellants Lang, b.

Hair spray products can be subdivided into six types on the basis of the hair fixative or film-forming component: polyvinylpyrrolidone, a copolymer of polyvinylpyrrolidone and polyvinyl acetate, shellac, dimethylhydantoin-formaldehyde resin, modified polyacrylic acid resin and lanolin Draize et al.

The first film-forming agent, shellac, was superseded in the s by polyvinylpyrrolidone. Better results are obtained with vinylpyrrolidone-vinyl acetate copolymers, the harder, more hydrophobic types being used for hair sprays. Still harder films can be obtained with vinyl acetate-crotonic acid copolymers. More recently, acrylate-acrylamide copolymers such as tert -butylacrylamide-ethyl acrylate-acrylic acid copolymers and octylacrylamide-acrylate copolymersvinyl acetate-crotonic acid-vinyl neodecanate copolymers and vinylcapro-lactam-vinylpyrrolidone-dimethylaminoethyl methacrylate copolymers have been used.

Ethanol, 2-propanol and acetone are the most important solvents in hair sprays. Dichloromethane has been used for many years —89 in the USA but is no longer used in some countries including the USA because of its toxicological properties Lang, b. Until recently, the most common propellants in aerosol hair sprays were chlorofluoro-carbons.

Those most frequently used were trichlorofluoromethane Ftrichloro-trifluoroethane Fdichlorotetrafluoroethane F and chlorodifluoromethane F Bycontroversy about the possible action of these compounds on the Earth's ozone layer led to a ban on their use as propellants in the USA International agreements and national legislation have led to a gradual abandonment of chlorofluorocarbons as propellants in Europe and elsewhere.

Alternatives are the hydrocarbons propane, butane, isobutane, pentane and their mixtures, although they are highly inflammable and poor solvents for most polymers Lang, b. Exposures to hair spray components in beauty salons have been estimated on the basis of both use patterns and direct measurements.

The average anti ride lizz xions release time per application is 10 sec, and about 10 g of spray are emitted during a spray period Gerkens et al. Half of the particle weight is solvent. It was estimated that 0.

Average exposure to dichloromethane while spraying from an aerosol can during one min period was 18 ppm in the breathing zone Sayad et al. Total particulate levels in personal samples in beauty salons ranged from 0. Brilliantine pomade is the oldest preparation for stabilizing styled hair.

Colourants added to brilliantine in the past were reported to have included N,N -dimethyamino-azobenzene para -dimethylaminoazobenzene; butter yellowauramine régime équilibré 5 kilos vite chrysoidine Clemmesen, ; Gubéran et al. Brilliantines consist mainly of vaseline and paraffin or other oils. The viscosity of the product and the hydrophobic layer with which it coats the hair are responsible for stabilization.

These and similar formulations have reappeared on the market as hair waxes. Setting gels are a new form of hair fixative. Fat-based gels are generally of the micro-emulsion type; aqueous gels are aqueous solutions thickened with poly ethylene glycolcellulose derivatives or polyacrylates and contain film-forming substances. Changes in fashion have meant that hair creams have lost much of their commercial importance.
