Int. Cl. A61k 7/12 US. Cl. 8-101 3 Claims ABSTRACT OF THE DISCLOSURE A system for semi-permanently dyeing human hair by plating out a water insoluble phthalocyanine dyestuif onto a cationic layer ensheathing hair strands and acting as a dye coupler for the dyestutf. The cationic layer is applied to the hair strands from an aqueous medium in which the cationic material and water insoluble phthalocyanine dyestuff constitute a single composite mixture with the cationic compound as an ingredient in intimate contact with the dyestuff and acting as a dispersant so as to obtain uniform distribution of the dyestuff in the aqueous medium and leveling of the dyestuff as a waterfast dye on the hair substrate.
BACKGROUND OF THE INVENTION (1) Field of the invention A dyeing system for human hair wherein an insoluble phthalocyanine dyestuff dispersed in an aqueous medium by a cationic dispersant is plated out as a waterfast dye onto a hair substrate that is coated with the cationic dispersant now acting as a dye coupler present as a layer on the hair shafts.
(2) Description of the prior art One of the present methods of dyeing human hair is referred to as temporary dyeing since the color is easily removed by shampooing. In this method, dyes such as nigrosine, resorcine brown, amarinth yellow, methylene blue, and gentian violet are coupled to hair strands. However, a major defect of such temporary dyeing products is their inherently light pastel colors. These light colors often have an artificial appearance and many of them are substantially or even completely removed when the hair is wetted with water. Temporary dyeing is practiced on hair on the human head; however, it also can be practiced on human hair not on the head, for example, wigs, switches, falls and wiglets. It is customary and, indeed, as a practical matter, almost imperative, for temporary dyeing to be practiced on light-colored hair, such, for example, as white hair, gray hair and stripped hair, that is to say that hair which is essentially uncolored.
SUMMARY OF THE INVENTION The present invention is concerned with an improved system of temporary dyeing of human hair, the new system, like the previous system, being applicable both to hair on the human head and to human hair off the head in the many forms in which it is available. Similarly, the present invention finds its principal advantage in the dyeing of non-colored hair, which is to say, white,
gray and stripped hair. It is to be noted that the stripped hair need not be completely stripped. The present invention will work Well with hair that has been partially stripped providing that the applied dyestuff is somewhat darker than the undyed hair. The stripping only has to be sufiicient to be a shade lighter than the ultimate color to be applied to the hair by the present invention.
It is an object of the invention to provide a system of the character described in which the dyeing of the hair, although temporary in a sense, is permanent to the extent that the dyestutt will not be removed when the dyed hair is wetted with water, i.e. the applied dye is waterfast; that is to say it is an object of the invention to provide such a system in which the dyestuff is water insoluble, although removable by shampooing, and in which the dyestuff is coupled to the hair by a water insoluble bond.
It is another object of the present invention to provide a method of dyeing human hair in which the resulting color will be as deep in shade, if desired, as a natural hair color.
It is another object of the invention to provide a system of the character described pursuant to which the dyeing of hair is accomplished more conveniently than it was heretofore by a permanent dye method.
It is another object of the invention to provide a system of the character described which will readily and fully satisfy the capricious nature of female patrons.
It is another object of the invention to provide a product which permits dyestuffs that are insoluble in water to be used in aqueous media for the dyeing of human hair.
It is another object of the invention to provide hair dyeing compositions which will fulfill the objects set forth above.
The present invention is based on the discovery that a certain type of water insoluble dyestuff dispersed in an aqueous medium will plate out on human hair, either on the head or off the head, the strands of which are coated with a cationic surfactant compound in the form of a layer that acts as a dye coupler binding the water insoluble dyestuff to the hair strands in a fashion such that the ensuing dye is waterfast but removable by shampooing.
Prior to application to the hair, the cationic surfactant compound even in the presence of the aforesaid special type dyestuff will not act as a dye coupler. This is an important achievement of the invention since it enables the cationic surfactant compound and the dyestuff to be applied to the hair from an aqueous medium in which the two, to wit the cationic surfactant compound and the special type of dyestuff, are present in a single composite aqueous mixture (composition) with the cationic surfactant compound in intimate contact with the dyestuff.
The dyestutf will be transferred from the aqueous medium to hair from the single composite aqueous composition, the cationic surfactant compound depositing as a layer on the hair shafts prior to deposition of the special dyestuff thereon. It has been observed that upon transference of the dyestuif to the human hair substrate a dye leveling is accomplished by the cationic surfactant compound which also acts as a dispersant prior to the application of the dyeing mixture to the hair strands, that is to say, as a dispersant for the water insoluble special dyestutf. Thereby, which is to say, by the dye leveling function, the cationic surfactant compound prevents an over build-up of the special dyestuff on the hair strands.
By the use of this dyestutf dispersing system, it has become possible to use dyestuffs for the dyeing of human hair which heretofore have been unsuitable for this purpose owing to their water insoluble character. However, in the system of the present invention, such water insolubility, instead of being a drawback, becomes an advantage because it prevents the loss of color which heretofore took place when the hair was wetted after having been dyed.
Nevertheless, the water insoluble dyestuif because of the special method of coupling the same to human strands through the use of a cationic dispersant can be removed with ease merely by shampooing. Hence the hair is, in effect, permanently dyed" for ordinary usage; but the dyestuff can be taken olf any time it is desired to change the same simply by resorting to shampooing so that a woman is not limited to the permanent presence of a given color water insoluble dyestuff on her hair and can have the same removed and a new color substituted with great case.
In the current vogue where fashion demands, or various occasions may call for, changes in hair color, it is not necessary for a woman patron to subject her hair to stringent dye stripping operations for the removal of ordinary permanent dyes since her new semi-permanent dyeing of the present invention can be removed and replaced without harsh treatment of her hair.
The dyestulfs of the present invention are phthalocyanine derivatives. The cationic compound is a cationic surfactant which is adsorbed by human hair from an aqueous medium to leave a coating layer thereof on the surface of the hair on to which the dyestuffs will plate and be coupled. 'Ihe cationic surfactant also acts as a dispersant in water for the water insoluble phthalocyanine dyestuff.
It is also useful to incorporate a non-ionic dispersant along with the cationic dispersant to improve dye dispersion as well as to enhance dye leveling. Furthermore to increase stability over a long-term shelf life, it is useful to employ a non-ionic thickener. The particulation of the dyestutf in the aqueous medium may be improved (made smaller in size) by use of a stabilizing agent that is a liquid wherein the dyestuff is initially soluble.
DESCRIPTION OF THE PREFERRED EMBODIMENTS The special type of dyestuffs which are critical to the proper functioning of the present invention must have the following properties:
( 1) They must be water insoluble.
(2) They must be phthalocyanine derivatives having the general formula:

Fe is a phthalocyanine radical which is either metal free or, more advantageously, metal-containing, in particular, heavy metal-containing, and, principally, coppercontaining;
x,, is a radical of a polyalkylene polyamine containing at least one lipophilic radical and at least 3 basic nitrogen atoms, which polyalkylene polyamine is bound at a terminal N atom to the S group;
x is the ammonium cation of such a polyalkylene polyamine; and
n and m are positive integers, m+m being equal to 2 to 4, m being at least 1 and n being 0, 1, 2, or 3.
.r and x are polyalkylene polyamine radicals of the general formula:
it being observed that an H of either R or R condenses with an OH of the suphonic acid group to link thereto.
Of the symbols R R R R and R at least one R represents a lipophilic radical. The lipophilic radical preferably is a saturated branched chain aliphatic group, advantageously containing 8 to 16 and, preferably, 8 to 12, carbon atoms, for example, the octyl, iso-octyl, decyl or dodecyl group. However, it is within the scope of the invention for the lipophilic radical to be an araliphatic group, for example, the benzyl group, which con contain saturated aliphatic substituents, eg a tertiary butyl, tertiary amyl, octyl, iso-octyl, decyl or dodecyl group. Also, if desired, the lipophilic radical can be a cycloaliphatic group, for example, a cyclohexyl group. The remaining Rs advantageously constitute hydrogen. However, they can also constitute a lower aliphatic group of one to two carbon atoms, for example, a methyl or ethyl group. In that part of the amine of Formula II, corresponding to x,,, however, at least one R must be hydrogen.
Each of Q and Q constitutes a lower alkylene radical, advantageously an o e-alkylene radical such as, for example, the l,2-propylene radical and, preferably, the 1,2- ethylene radical. However, each of Q and Q can also be an urn-alkylene radical such as, e.g., the 1,3-butylene radical and preferably the 1,3-propylene radical. Preferably Q and Q are the same. p represents a positive integer, preferably l, 2 or 3.
The dyestuffs of the general Formula I are well-known dyestuff; however, for the purpose of further identification it may be mentioned they can be obtained by reacting one mole of a phthalocyanine compound of the general Formula III with m-l-n moles of a polyalkylene polyamine which contains at least one lipophilic radical and at least 3 basic nitrogen atoms. The reaction time typically is about hours at atmospheric pressure at a temperature of between about 20 to about C. The formula for the phthalocyanine compound is:
[SOiCll sotZ] wherein:
Fe, m and n have the definitions given above and wherein Z is hydrogen, an alkali metal or an ammonium ion.
The aforesaid reaction is advantageously performed in an aqueous suspension and with the addition of inert organic solvents which are miscible with water and of acid combining agents, all as is well-known in the art.
The dyestulfs of Formula I, i.e. the dyestulfs constituting phthalocyanine derivatives as specified, are powders of various colors most of which are blue-black and yield various colors as will be specified hereinafter when applied to the hair in accordance with the invention and also in diluted aqueous dispersions.
The dyestuffs are insoluble in water and are difliculty soluble in lower alkanols, such as, e.g. methanol or ethanol, as well as in lower ketones such as acetone. On the other hand said phthalocyanine derivative dyestuffs are easily soluble in several higher alcohols, such as, e.g. benzyl alcohol, or in several ether alcohols, such as e.g. diethylene glycol monoalkyl ethers, e.g. in diethylene glycol monomethyl ether.
The present invention provides hair dyeing compositions which essentially comprise an aqueous liquor, i.e. medium, containing a colored substance selected from the group consisting of one or more of the aforementioned water insoluble phthalocyanine derivative dyestuffs in an amount of between about 0.15% to about 0.25% by weight based on the total weight of the composition, and a cationic surfactant (dispersant) which is dispersible in water, rises to a maximum and then decreases again as the which is adsorbed by human hair from the hair dyeing amount of cationic dispersant present is further increased. composition, leaving a layer thereof on the surface of the Although the method and system will not work without hair, and which is a dispersant in water for the said water this cationic dispersant, a concentration in excess of the insoluble dyestuif at room temperatures.
