Lightly ammoniacal bleaching compositions-

The present invention relates to compositions for bleaching the hair, which contain a large amount of water-soluble surfactants and water-soluble compounds and a small amount of ammonium ions. in the aqueous phase, which significantly reduces the release of gaseous ammonia and makes the compositions more pleasant.

Any process aimed at treating the hair must be established taking into account a large number of variables. Discoloration is basically a nn-rrFT-Mnu np-naLdi removal process.

natural coloring of the hair. The coloring of the hair, that is to say the degree of lightening of the hair which is desired, can range from a simple lightening to the palest blonde. The bleaching compositions must therefore be capable of inducing moderate to intense lightening, passing through all the intermediate degrees. In addition, the hair can be bleached in whole or only in certain places, namely in the newly appeared parts or "hair roots". The bleaching compositions used for bleaching in highlights, in frost or at the tips of the hair can be applied by the person himself or by the hairdresser for the production of special effects.

The bleaching compositions used for the hair differ from the bleaching compositions used for textiles and fabrics, for cleaning. . t hard surfaces, etc., because the compositions for bleaching the hair, in addition to oxidizing and destroying the melamine which colors the hair, must be able to. see be used in contact with the skin and can not unduly damage the hair. In addition, since bleaching compositions for the hair fall into the class of cosmetics, it is desirable that they be pleasant to use. Finally, it is desirable that a composition for bleaching the hair eliminates as effectively as possible the shade imparted by melamine both for reasons of convenience and to avoid degradation of the hair and irritation of the skin and scalp. .

\

Most bleaching systems require contact with the hair for a few minutes to 2-3 hours, depending on the degree of bleaching desired.

Bleaching compositions for the hair against - -. ί usually exist as an oxidant, which is a peroxide, in agents that enhance discoloration, and in various cosmetic agents and stabilizers for additional bleaches. Oxidizers such as the various hypochlorites and derivatives of halogenated cyanuric acids suitable for compositions for cleaning hard surfaces and compositions for bleaching textile materials cannot be used on the hair because they damage it too much and are too irritating to the skin. The peroxides applied to the hair must be activated, the operation being carried out using an activator which adjusts the pH in the basic range.

The most common agent for adjusting the pH of peroxide-containing hair bleaching compositions is aqueous ammonia, commonly known as ammonium hydroxide. '·

It is known that the aqueous solutions of certain [. applied, in particular hydrogen peroxide and compounds releasing hydrogen peroxide, such as peroxycomposites, for example persulfates, perborates and percarbonates, are effective for bleaching hair or materials containing keratin. To accelerate the bleaching by these hydrogen peroxide products, the latter is used together with an activator, which is generally a compound forming ammonium hydroxide or an alkali or alkaline earth metal hydroxide.

Oheveluré lotions used in two or three component systems typically contain 2 to 5.5% ammonium hydroxide. As a rule, at least half of this amount is not neutralized and exists in the lotion in the form Due to the high concentration of neutralized ammonium ions and. | ammonium ions not neutralized, current bleaching systems in current use have a characteristic ammoniac odor. Therefore, bleaching compositions are not as pleasant to use as other cosmetic compositions.

However, the replacement of the ammonium hydroxide by a less volatile amine of higher molecular weight makes the bleaching composition more aggressive with respect to the keratin of the hair for the same degree of lightening. For example, United States patent No. 2,283,350 describes the use of aliphatic amines and hydroxyaliphatic amines replacing ammonium hydroxide in compositions for bleaching hair. . On the other hand, U.S. Patent No. 3,816,615 describes compositions for bleaching the hair which contain guanidine derivatives instead of ammonium hydroxide.

jf Furthermore, to be effective, a bleaching composition must remain in place for the time necessary to effectively lighten the hair and maintain, during its stay, the alkalinity and the moisture content suitable for continuing bleaching. The bleaching composition must form a foam of limited height and of a viscosity sufficient to maintain the bleaching constituents and the oxygen released in contact with the hair. Conventional bleaching compositions for this purpose contain significant amounts of different thickeners, oils and fillers which are not soluble in water. For example, | } US Patent No. 3 * 651-209 describes the use of calcium carbonate,. magnesium carbonate, calcium sulfate. and other inert fillers such as talc, kaolin and bentonite as thickening agents suitable for bleaching compositions. "White henna" ............. *: ν, ο · ösu-a-ax a mixture of 'magnesium carbonate with magnesium oxide, magnesium trisilicate, etc .) and other insoluble absorbents have also been described as useful auxiliaries for increasing the viscosity of bleaching compositions. j

V

The hair lightening lotions currently in use also contain, as is known, significant amounts of esters, alcohols, ethoxylation products and / or propoxylation products which are not soluble in water, which confer viscosity - The most commonly used alcohol is oleyl alcohol, which is a C ^ g alcohol. Water-insoluble surfactants form gels when the lotion is mixed with an aqueous solution of hydrogen peroxide. The water-insoluble gel helps maintain the bleaching mixture on the hair ... and prevents it from flowing from the hair. However, ·.

, the use of water-insoluble surfactants greatly influences the bleaching power of the mixture. To compensate for the loss of bleaching power, the ammonia concentrations must be high. The study of the system shows that as the surfactant becomes more and more insoluble in water, the bleaching power of the mixture decreases. The functional radical of the surfactant does not seem to have much effect on the effectiveness of the bleaching mixture, provided that the solubility in an aqueous medium remains.

Therefore, to produce a bleaching composition. improved peroxygen having only a very weak unpleasant ammoniacal odor and having the right consistency during all the discoloration to lead to good results, while keeping damage to the hair to an acceptable minimum, it is possible, as the Applicant has discovered with, surprise, keeping the concentrations of both amines and water-insoluble constituents to a minimum. Therefore, bleaching lotions must contain surfactants which form soluble gels when mixed with peroxides and / or persulfates. The above solubility / gel formation criteria in practice limit the nature of the surface-active agents which it is possible to use.

Consequently, according to one of its aspects, the subject of the invention is a thickened composition for bleaching the hair which comprises: (a) 2 to 20 $ by weight of at least one per-compound chosen from perborates, persulfates , percarbonates and carbonates peroxohydrates of ammonium and alkali and alkaline-earth metals; (b) 1.5% to 7% by weight of hydrogen peroxide; (c) an amine or a quaternary ammonium compound chosen 1 - from ammonium hydroxide, morpholine, the mono-, di- and trialkanolamines- and mono-, di- and trialkylamines, including the alkyl or alkanol radical has 1 to ^ carbon atoms; (d) * + to $ 8 by weight of at least one water-soluble surfactant thickener; (e) a buffer for maintaining the composition at a pH of approximately 9 to 12, and (f) for the remainder, of water, the concentration of ammonium ions in the aqueous phase being less than approximately 0.55 %; by weight, on the basis of the complete composition, so that in substance only traces of gaseous ammonia are released as a result of an interaction of the constituents with each other or with the hair.

In addition, the composition according to the invention may contain respectively up to approximately 0.5% by weight of a sequestering agent, 1.5% by weight of a viscosity modifier and 20% by weight of at least one additional water-insoluble constituent chosen from surfactants, perfumes, oils, opacifiers and colorants.

Preferably, the composition in accordance with the invention may contain, respectively, approximately 6 to 8% by weight of the per-compound and 3.2 to. 3.7% by weight of hydrogen peroxide and comprises as water-soluble surfactant thickener the ethoxylation product formed of 8.5 moles of ethylene oxide and 1 mole of coconut fatty acid. In addition, the pH of the resulting composition is preferably from 9.7 to 10.3; the water-soluble thickening surfactant can be chosen from: · (a) an alkylene glycol or an ether-alcohol d 'alkylene glycol of formula: i &) (r1o) r2oh / nl ί ï- · where represents a hydrogen atom or an alkyl radical 7 of 1 to b carbon atoms, K and R' represent divalent alkylene radicals of 2 with b- carbon atoms and n 1 represents a number from O to l ^ O; (b) a long chain fatty acid soap of formula: 2 (R3C00) aK 1 3

Q

where R represents the hydrocarbon radical of a long chain fatty acid of 10 to 20 carbon atoms, H represents a monovalent or polyvalent salifying radical and "a" represents the value of the radical M; . . (c) a long-chain polyoxyalkylated compound chosen from a long-chain polyoxyalkylated fatty alcohol, a poly-hydroxyalkyl ester of a long-chain fatty acid, a long-chain polyoxyalkylated amine, a long-chain polyoxyalkylated fatty acid , a long-acid fatty acid amide CD-CH-MTYR. q - 7 - np_nqhh polyoxyalkylated chain, an alkylphenol with long polyoxyalkylated chain, and laurates of sorbitol and its polyoxyalkylated anhydrides having approximately 8 to 300 oxyalethyl radicals, and (d) mixtures thereof.

The thickened compositions for bleaching the hair which are the subject of the invention generally have a viscosity of 5,000 to 100,000 centipoise.

As already indicated, it is common practice to incorporate an amine or a quaternary ammonium compound in · a peroxygen bleaching system for the activation of bleaching *

Discoloration studies have unexpectedly revealed that very good shade clarification resulting in minimal degradation of the hair can be achieved using lotions with an ammonium ion concentration of 0.55% by weight if not less, on the basis of | . weight of the complete composition, while the aqueous phase forms 80 to 100% of the weight of the complete composition. Studies have also revealed that the discoloration of the hair is not appreciably influenced by ammoniacal alkalinity, that is to say that ammonia can be nominally present both in free form IH ^ .H ^ O and in form neutralized in ammonium ions From a cosmetic point of view, the ammonium ion is preferable to free.

Because of the balance between Mi, Hi, O, and OH, it is not possible that only one species exists in an aqueous medium. The relationship between and * can be shifted by pH, ionic strength, pressure, or any other chemical variable that influences the concentration of * each species in the equilibrium relationship. However, the simple reduction of the amine or quaternary ammonium content, without simultaneously maintaining higher concentrations of water-soluble constituents, or vice versa, in accordance with the present invention, does not give satisfactory results for the bleaching of the hair. In addition, to try to compensate for the inferiority of discoloration resulting from the use of lower concentrations of amine or of quaternary ammonium either by choosing high concentrations of peroxygen compounds or of alkaline agents, or by increasing the time of discoloration of the hair or the temperature for discoloration, it induces degradations such that discoloration is no longer satisfactory. The invention aims to adjust the constitution of the mixture so as to promote the formation of quaternary ammonium ions and to maintain the concentration of free ammonia as close as possible to the value imposed by the equilibrium constant.

One of the essential constituents of the bleaching compositions I in accordance with the invention is at least one per-compound in useful concentration of approximately 2 to 20% and preferably from 6 to 8%. It should be noted here that for the purposes of the invention, the percentages are given by weight, based on the total weight of the composition, unless otherwise indicated. Perco-compound is an additional source of oxygen necessary for discoloration, apart from hydrogen peroxide. These percomposites can be chosen without limitation from perborates, persulfates, percarbo-nates and carbonates peroxohydrates of ammonium and alkali and alkaline earth metals. The ex- * - pressure "alkali and alkaline earth metals" should be understood in its usual sense.

It is also essential that the composition contains hydrogen peroxide in a useful concentration of about 1 to 7% to ensure discoloration of the hair.

Stabilizers for hydrogen peroxide, such as phenacetin, may also be present in minor amounts.

Preferably, the hydrogen peroxide concentration is 3.2 to 3.7 #.

A third essential constituent is an amine or a water-soluble quaternary ammonium compound ensuring the necessary activation of hydrogen peroxide for a more effective discoloration and also serving as a pH regulating agent further promoting the thickening of the composition by formation of water-soluble soapy gels with fatty acids. The most frequently used and preferred amine or quaternary ammonium compound is ammonium hydroxide because this compound is easy to obtain and is effective as an activator of hydrogen peroxide. However, other less effective amines can also be used, normally in larger amounts, for example an amine 1 or a quaternary ammonium compound chosen from morpho line, mono-, di- and trialkanolamines and mono-, di- and trialkylamines in which the alkyl or alkanol radical has 1 to h carbon atoms, these compounds can also be taken as a mixture.

As already indicated, it is critical that the concentration of ammonium ions in the aqueous phase of the bleaching composition be less than about 0.55% to prevent the formation of more traces of gaseous ammonia by the composition during bleaching of the hair. and thus avoid the traditional disadvantages and obtain a good result from the cosmetic point of view. It is therefore obvious that the. concentration reached in ammonium ions results from many factors, one of which is very important, is the quantity of ammonium compounds, in particular the ammonium compounds composed of the composition, which are capable of ionizing in * water forming ammonium ions. The concentration of ammonium ions is also influenced by the quantity of other compounds which react with ammonium ions, for example neutralizing them, as is the case with fatty acids. Finally, certain factors are associated with the solution balance between ammonium ion, ammonium hydroxide and gaseous ammonia. In addition, it should be noted that the replacement of ammonium hydroxide with amines does not cause the ammonium ion to appear, but requires larger amounts of reagent due to lower efficiency than that of hydroxide. 'ammonium.

It is essential to add about ^ to 8% of at least one water-soluble surfactant thickener. These compounds are conventional for the specialist. For example, such water-soluble surfactant thickeners are those described as "coupling agents" from line 29 of column 5 | at line 56 of column 6 in United States patent 3,8H,83O. In addition, useful compounds are the laurates of sorbitol and its ethoxylated anhydrides which include, for example, 80 units of ethylene oxide (Tween 80), acid ethoxylates, such as condensed distearic acid with · 1 ^ 0 units of ethylene oxide (polyoxyethylene glycol 6000 distearate) and block copolymers of ethylene oxide and propylene oxide (Pluronics). A preferred surfactant is an ethoxylated coconut fatty acid. taking on average 8.5 units of ethylene oxide - The pH range useful for the application of the •. bleaching positions of the invention extends from about 9 to 12 and preferably from about 9.7 to 10.3 · When the fold is less than 9, the discoloration is insufficient, while beyond 12 , the hair is too damaged.

To maintain the pH within the proper range, a pH buffer or adjusting agent has been found to be essential. In addition to the amine or quaternary ammonium compound establishing certain alkalinity, useful agents are the alkali metal metasilicates, such as sodium meta-silicate, or the alkali metal carbonates, orthophosphates, meta-phosphates and tripolyphosphates. .

Finally, water is an essential constituent which forms the medium suitable for advancing discoloration, as already indicated, and constitutes the rest of the composition with the exception of the constituents insoluble in water and other additives which 'we can add possibly.

Among the other additives which may be optionally added, it is worth mentioning sequestering agents to complex the ionic metallic impurities which could adversely affect the stability of hydrogen peroxide. These sequestering agents which can be present in an amount up to about 0.5% are in particular the non-neutralized form or the form salified by the alkali metals of nitrilo-triacetic acid and of alkylene polyamine polycarboxylic acids of the formula :

(hoocch2) 2îst [(CH2) xNCH2cooïï] 5rcn2cooH

where x and y vary independently from 1 to ’t. Examples of such acids are ethylenediaminetetraacetic acid and ethylenediaminetriacic acid.

The composition may also include in an amount up to about 1.5 # a viscosity modifier which may include water-soluble straight chain aliphatic alcohols (such as ethanol or butanol), aldehydes (such as acetaldehyde) and butyraldehyde), ketones (such as acetone and 2-hexanone) and glycols (such as ethylene glycol and butylene glycol).

In addition, the compositions can optionally comprise up to approximately 20% of at least one additional constituent which is not soluble in water, comprising, for example, surface-active agents, perfumes, oils, opacifiers and dyes (soluble dyes and pigments scattered).

Such dyes are, for example, green D&C # 6, yellow ED&C # 3 and pigments like Overseas God and "scattered blue # 1.

* Typical opacifiers are ahietic / lauric polyether ethers and polystyrene.

Useful oils are in particular non-volatile oils, such as mineral oil, isopropyl myristate, diisopropyl adipate and volatile or essential oils, such as mint essence, clove essence and essence eucalyptus.

Typical examples of the water-insoluble surfactants which can be used for thickening and emulsification are the conventional compounds of this kind mentioned from line 6½ of column 3 to line 6 of column 5 "of the patent of the United States of America, n ° 3.811 * 830 and called" oily materials ".

Other additives which may be added are in particular fats and waxes which are not soluble in water of natural or synthetic origin, such as beeswax or spermaceti, and emollients for the skin, of the conventional type.

It should again be noted that the use of thickeners water-soluble surfactants is essential, possibly in combination with limited quantities of the aforementioned constituents which are not soluble in water, for the formation of bleaching compositions with weak ammoniacal conform to the invention. It should be noted that the use of natural gums, such as xantliane gum or cyamopsis gum, and cellulose thickeners, such as carboxymethylcellulose derivatives, in the presence or absence of solvents such as low molecular weight alcohols and ketones does not allow the thickening which is required for the purposes of the invention. The gums and cellulosic agents are too difficult to mix or require too long a hydration period to establish the necessary viscosity and the maintenance of the bleaching composition on the hair. The solvents which generally cause an association between the liposoluble compounds and the water-soluble surfactants give compositions with low viscosity and are not suitable for bleaching the hair.

The tests applied in the examples below to evaluate the discoloration (that is to say the efficiency of lightening-j. Curing of the shade of the hair) and the solubility in an alkaline medium (i.e. - say the degradation of the hair) are described below.

Discoloration effectiveness evaluation test

Surfactants and their effect on bleaching and degradation of the hair are appreciated using a ternary system. This system includes a powder activator, a lotion and a developer. The chemical composition of the activator and that of the developer are kept constant., The lotion constituting the vehicle for the evaluation of the surfactant. The activator has the following constitution.

the discoloration tests are carried out as described below.

23 g of the activator are added to 120 ml of a 6% aqueous solution of hydrogen peroxide and the mixture is stirred, i 60 g of the experimental lotion are then added and the whole is stirred until mixed respondent. The pH and the viscosity of the mixture are then determined. The mixture is spread over and in a lock of “brown” pigmented hair. The lock consists of a mixture of virgin commercial hair with a length of approximately 23 cm. The bleaching is carried out in a glass bowl placed on a bath. -marie maintained at 38 ° C. The duration of bleaching is 60 minutes and the wick is turned over and the bleaching mixture reworked every 15 minutes. After 60 minutes, the bleaching mixture is removed from the hair by rinsing and the wick is washed with a mild shampoo • The wick is then visually compared to a standard.

If the discoloration of the wick makes it comparable to the standard, the reflectance of each wick is precisely measured at 560 uyi using a Beckman DU-2 spectrophotometer.

If the surfactant is a powder, the monoethanolamine and the solid surfactant are dissolved in the 6% hydrogen peroxide solution. The activator is then added to the resulting mixture of lotion and peroxide and the whole is stirred until uniform. Discoloration is carried out as described above.

Solubility test in alkaline medium

Hair strands are bleached at 38 ° G for 1 hour in bleaching composition. 1 g of bleached hair is then dried for 3 hours at 110 ° C. We weigh the dried hair. The hair is then immersed for 1 hour in 5 ml of 0.1 Ή sodium hydroxide at 66 ° C. The hair is removed from the sodium hydroxide solution and rinsed with distilled water. They are then rinsed with 1% acetic acid. The hair is rinsed again with distilled water. The hair strand is dried for 3 hours at 110 ° C. The weight of the wick is determined and the weight loss is calculated. The deterioration of the hair during bleaching is all the more important as the weight loss is higher.
