DESCRIPTION:
BRIEF SUMMARY
DESCRIPTION
The subject matter of the invention is compositions for the grooming of hair which need not be rinsed out and which contain tetraoxyethylene lauryl ether and a quaternized copolymer of vinyl pyrrolidone with dimethylaminoethyl-methacrylate (80:20).
Hair care compositions are used for improving the condition of the hair and are usually oil-in-water emulsions which contain oily, semisolid or solid substances, for instance, paraffin oil, vaseline, wool fat, wool fat alcohol, fatty acid ester and hydrocarbon waxes, as framework components. Normally, quaternary ammonium compounds such as oxyethylated alkyl ammonium phosphates, alkyl trimethylammonium chlorides, dialkyl dimethyl ammonium chlorides, alkyl dimethylbenzyl ammonium chlorides and alkyl pyridinium chlorides are used alone or in combination with nonionogenic emulsifiers as emulsifiers for such emulsions. Aqueous solutions and aqueous gels with a quaternary ammonium compound content are also frequently used as hair care compositions.
The aforementioned monomeric quaternary compounds serve at the same time to improve the ease of combing when wet and the feel, particularly of damaged hair.
However, such additions of quaternary ammonium compounds impair the physiological compatibility of such preparations, particularly the eye's tolerance to them.
It has now been found, however, that a surprising and outstanding improvement in the ease of combing of hair is brought about by means of compositions for the grooming of hair based on an aqueous, alcoholic or aqueous-alcoholic solution of a quaternized copolymer and an oxyethylated fatty alcohol, as well as possible propellants and other additions, characterized in that they contain
(a) 0.01 to 0.09 percent by weight quaternized copolymer of vinyl pyrrolidone and dimethylaminoethylmethacrylate (80:20) as film forming resin and
(b) 0.01 to 0.5 percent by weight tetraoxyethylene lauryl ether as oxyethylated fatty alcohol.
The copolymer of vinyl pyrrolidone and dimethylaminoethylmethacrylate mentioned in (a) is preferably quaternized with dimethyl sulfate or diethyl sulfate. The commercial products GAFQUAT.RTM. 734 AND GAFQUAT.RTM. 755 of the GAF Corporation, New York, are suitable as the quaternized copolymer of vinyl pyrrolidone and dimethylaminoethylmethacrylate (80:20). They have the following formula: ##STR1##
In GAFQUAT.RTM. 755N the average molecular weight is approximately 1,000,000 (g/moles) and, in GAFQUAT.RTM. 734, approximately 100,000 (g,moles).
Tetraoxyethylene lauryl ether of the formula
In the compositions according to the invention, the tetraoxyethylene lauryl ether is contained in a quantity of 0.01 to 0.5 percent by weight, preferably 0.03 to 0.09 percent by weight. The content of quaternized copolymer of vinyl pyrrolidone and dimethylaminoethylmethacrylate is 0.01 to 0.09 percent by weight, preferably 0.03 to 0.07 percent by weight. Ethyl alcohol and isopropyl alcohol, or mixtures of these two alcohols, can be contained in the compositions, according to the invention, in quantities of 0 to 99.98 percent by weight. Of course, other cosmetic additions for hair, such as perfume oil, herbal extracts, bactericides or fungicides, anti-dandruff agents and dissolving intermediaries for perfume oil, can also be contained in the compositions according to the invention, insofar as such additions appear useful and advisable. Furthermore, tinting dyes for tinting the preparation of dyes to be absorbed directly by the hair in order to simultaneously shade the hair can also be contained.
Of the latter dyes, which can be present individually or in combination, the following classes are mentioned by way of example: aromatic nitro dyes, e.g. 1,4-diamino-2-nitrobenzene, azo dyes, e.g. Acid Brown 4 (C.I. No. 14 805), anthraquinone dyes, e.g. Disperse Violet 4 (C.I. No. 61 105) and triphenylmethane dyes, e.g. Basic Violet 1 (C.I. No. 42 535), wherein the dyes of these classes can have an acidic, nonionogenic or basic character, depending on their type of substituents. The total concentration of the latt
