Description
The present invention is directed to compounds for dyeing hair, to compositions containing said compounds and to the use of said compounds for dyeing hair.
According to current practices, oxidation hair dyes are used for dyeings which are resistant, for several weeks, to shampoo, light and weather conditions.
Said oxidation dyes are based on aromatic compounds of the diamine, aminophenol or phenol type. Said compounds are not generally dyes per se but are converted into dyes, by condensation in the presence of an oxidizing medium, generally formed of oxygenated water. Oxidation dyes can be classified as "bases" which are para- or ortho-derivatives of the diamines and aminophenols and as "couplers" (or modifiers) which are meta derivatives including, for instance, meta-diamines, m-aminophenols or polyphenols.
The color of the oxidation dyes is developed in the presence of hydrogen peroxide in a basic medium, generally ammoniacal, which allows both decoloring the hair and dyeing it to the desired color. The oxidation dye dyeing operation is in fact a complex operation which encompasses both a decoloration (lightening or stripping) action and the dyeing action itself.
The dye compositions, also referred to as dye vehicles or dye carriers, may take the form of creams or of liquids gelatinizable by dilution.
Generally, said creams contain either fatty acid soaps containing 12 to 18 carbon atoms or fatty alcohols in the presence of anionic or nonionic emulsifiers.
Generally, the gelatinizable liquid contains either nonionic oxyethylenated or polyglycerolated compounds and solvent or liquid fatty acid soaps, such as oleic acid or isostearic acid, and solvent.
Alkalizing agents used to make soaps include potash, soda, ammonia, monoethanolamine, diethanolamine or triethanolamine.
By employing oxygenated water at the dilution ratios most frequently employed (from 1 to 3 times) so as to obtain a composition containing sufficient quantities of oxygenated water and ammonia to obtain lightening, the dye vehicles in the form of a cream yield a cream while the dye vehicles in the form of a gelatinizable liquid yield a gel.
These vehicles can be improved by the addition of cations which favor the disentangling of wet hair and provide dry hair with a certain softness and a certain shine.
Often, dye compositions in the form of creams are used to provide white hair with good coverage but with attendant detriment to the luminosity of sheen, while gelatinizable liquid dye compositions result in very luminous nuances but provide inferior coverage of white hair, compared to the creams.
The invention resides in the discovery that especially interesting results are obtained by preparing a composition for oxidation dyeing, which is to be diluted with an oxidizing solution, by admixing at least one fatty acid, at least one cationic polymer of a special class, benzyl alcohol and at least one alkalizing agent optionally in a mixture containing the conventional ingredients of a dye vehicle, including the dye(s), thickener(s), solvent(s), sequestering agent(s), anti-oxidizing agent(s) and the like.
The hair dyeing composition of the invention is characterized by effecting less damage to hair compared to products currently in use.
The hair dyeing composition of the invention also confers excellent disentangling properties and a pleasant feel to wet or dry hair.
After hair is dyed with the composition of the invention, it is strong, fluffy, shiny and non-electric.
Furthermore, the coloring resulting from use of the dye vehicle is especially remarkable in providing good coverage as well as luminosity and sheen, to white hair and provides nuances uniformly, while being resistant to light and shampoo.
The invention is particularly directed to a hair dye composition which is to be diluted with an oxidizing solution, containing at least one oxidation dye and a vehicle wherein the vehicle comprises at least one fatty acid, at least one alkalizing agent in an amount which is in excess of the stoichiometric quantity necessary for neutralizing the fatty acid, benzyl alcohol in an amount of from 2 to 20% by weight of the composition and at least one cationic polymer, present in an amount of from 1 to 15% by weight of the composition, formed of repeating units of the formula ##STR2## in which: R.sub.1 and R.sub.2 are alkyl of 1 to 3 carbon atoms, and R.sub.3 and R.sub.4 are alkyl or hydroxyalkyl of 1 to 3 carbon atoms; R.sub.2 and R.sub.4 may also represent alkyl of 4 to 8 carbon atoms when R.sub.1 =R.sub.3 =CH.sub.3, and in this case R.sub.2 and R.sub.4 are identical; and R.sub.4 may also represent benzyl, cyclohexyl or alkyl of 4 to 12 carbon atoms when R.sub.1 =R.sub.2 =R.sub.3 =CH.sub.3 ;
A and B are the same or different and each of A and B is alkylene or alkenylene, linear or branched, of 2 to 20 carbon atoms; --(CH.sub.2).sub.n --O--(CH.sub.2).sub.n --, --(CH.sub.2).sub.m --NH--CO--NH(CH.sub.2).sub.m --, --CH.sub.2 --CH(OH)CH.sub.2 -- or --CH.sub.2 --C.sub.6 H.sub.4 --CH.sub.2 --; each of n and m is a whole number equal to 2 or 3 and X.sup..crclbar. is a cosmetically acceptable anion.
The fatty acid component of the composition contains 12 to 20 carbon atoms, preferably 12 to 18 carbons and can be natural or synthetic fatty acid(s). Examples include lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, oleic acid, arachic acid, ricinoleic acid, phenylstearic acid, linoleic acid or mixtures thereof.
The alkalizing agent can be sodium hydroxide, potassium hydroxide, ammonia, monoethanolamine, diethanolamine, triethanolamine or mixtures thereof.
The presence, in the dye vehicle, of at least one fatty acid and at least one alkalizing agent allows formation of a fatty acid soap in situ.
In the dye vehicle of the invention, the concentration in fatty acid (before dilution) is from 5 to 30% and preferably from 10 to 25% by weight.
The alkalizing agent is present in excess of the stoichiometric quantity corresponding to the neutralization of the fatty acid. This excess represents from 1 to 30% of the total weight of the composition (prior to dilution).
Among the polymers having repeating units of Formula I (hereinafter referred to as polymers of Formula I), are those for which (1) R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are identical and each is alkyl of 1 to 3 carbon atoms, and (2) R.sub.1 is identical to R.sub.2 and R.sub.3 is identical to R.sub.4, with R.sub.1 and R.sub.2 representing alkyl of 1 to 3 carbon atoms and R.sub.3 and R.sub.4 representing hydroxyalkyl of 1 to 3 carbon atoms; and more particularly those in which each of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is methyl, ethyl, or propyl or R.sub.3 and R.sub.4 represent 2-hydroxyethyl, 2-hydroxypropyl or 3-hydroxy propyl, or R.sub.2 and/or R.sub.4 represent butyl; those in which A and B, identical or different, represent an alkylene of the formula

The anti-oxidizing agents, which are present in a quantity sufficient to prevent premature oxidation of oxidizable components during storing of the composition, are for example sodium or potassium bisulfite, thioglycolic acid, hydroquinone, etc.
The vehicle or support according to the invention can be in the form, before dilution, of either a clear liquid or in the form of a cream.
According to the preferred production method for the invention, the support is in the form of a liquid. This liquid form is obtained by using one or several liquid fatty acids such as for example oleic acid or isostearic acid, possibly in a mixture with other fatty acids in proportions such that the mixture remains a liquid. Alkalization is effected preferably by ammonia and/or mono- or di-ethanolamine, the alkalizing agent being in excess of 1 to 30% as previously indicated. In a preferred production method for dilution of said liquid dye composition, the alkalizing agent is a mixture of ammonia and mono- or di-ethanolamine, the mono- or di-ethanolamine being in a stoichiometric quantity in relation to the fatty acid, and the ammonia being in sufficient quantity to obtain the lightening effect, i.e., preferably a quantity of ammonia of from 7 to 15% by weight in relation to the weight of the composition.
Of course, in compositions according to the preferred production method, the conventional adjuvants possibly present are the appropriate adjuvants for the production of liquid compositions.
According to this preferred production method, benzyl alcohol, present at a concentration of from 5 to 15%, is associated with at least one solvent previously cited, used at a concentration of from 2 to 20% and preferably 5 to 15%.
Preferred amides include oleic or lauric diethanolamide, mono- or diethanolamide of copra.
Preferred fatty acids include oleic, lauric, octyldodecyl, hexyldodecyl, hexyldecyl and isostearyl alcohols.
Surprisingly, it was discovered that a liquid vehicle of the invention, appearing as a clear liquid, gives, after dilution with oxygenated water used as diluent in a ratio of 1 to 2 and preferably 1, a mixture having the appearance and consistency of a cream and not a gel as might be expected.
The liquid support according to the invention provides for using gelatinizable liquids (which are gelatinized by admixture with the oxidizing agent) which also has the advantages of a cream once the mixture is prepared, that is, ease of application and good adherence to the hair.
Furthermore, the coloring qualities are excellent, combining the coverage qualities obtained with the cream supports to the qualities of transparence and shine obtained with the gel supports.
The pH of dye compositions of the invention may vary from 5 to 11, and preferably from 8 to 10.5.
The compositions of the invention are used for dyeing hair in the customary manner after the addition of an oxidizing agent.
The concentration of oxidizing base may vary from 0.001 to 10%, and preferably from 0.03 to 5% by weight, and that of the coupler may vary from 0.001 to 5%, and preferably from 0.015 to 2% by weight of the composition.
One part by weight of the dye composition may be mixed with 1 to 3 parts by weight of oxidizing agent.
The setting time may vary from 5 to 45 minutes and preferably from 15 to 30 minutes.
Another object of the invention is a hair dye composition which results from mixing the composition to be diluted such as previously defined and an excess of oxidizing solution.
The oxidizing solution is especially a solution of oxygenated water. By oxygenated water is meant hydrogen peroxide. It will be noted that a H.sub.2 O.sub.2 solution having a concentration of n volumes is a solution which may give by decomposition n liters of oxygen, under normal conditions, by the reaction:
Another object of the invention is a procedure for dyeing the hair characterized by the fact that such a dyeing composition is applied to the hair in sufficient quantity to obtain the desired tint.
