DESCRIPTION:
BRIEF SUMMARY
The subject matter of the invention relates to hair treatment agents, which contain cetyl alcohol lactic acid ester, hereinafter called cetyllactate, and at least one quaternary monomer ammonium compound in an alcoholic solution as well as hair treatment processes by using these hair treatment agents.
The hair structure is damaged by frequent bleaching, permanents and coloring, but also due to frequent washing with deoiling air entrainers and by intensive reaction to sunlight. The hair becomes brittle and it looses its luster. Furthermore, while combing the hair it is electrostatically charged and the roughened hair surface causes felting and knotting of the hair. This makes combing difficult. Therefore, hair treatment to improve combability has attained a considerable importance.
Hair treatment agents act for improving the hair condition and customarily are oil-in-water emulsions, which as a framework contain components of oily, semisolid or solid substances like, for example, paraffin oil, vaseline, wool fat, wool fat alcohols, fatty acid ester oils and hydrocarbon waxes. As emulsifiers for such emulsions customarily quaternary ammonium compounds are used, like oxethylized alkyl ammonium phosphates, alkyl trimethyl ammonium chlorides, dialkyl dimethyl ammonium chlorides, alkyl dimethyl benzyl ammonium chlorides and alkyl pyridinium chlorides alone or in combination with noniogenic emulsifiers. Also watery solutions and watery gels with a content of quaternary ammonium compounds are frequently used as a hair treatment agent. Such agents are frequently distributed on the hair in form of a clear hair care rinse, for example, or in form of an emulsion as a so-called creme rinse after the hair wash on the still wet hair, it will remain active on the hair for a few minutes and is then rinsed off with water.
The wet combability and the touch of the hair can be improved to a certain extent with hair treatment agents on the basis of monomer quaternary ammonium compounds.
In agents for the treatment of hair it is also known to use them as conditioners when the agents contain cationic active polymers, in particular polymers which contain quaternary ammonium groups. In view of an alternating reaction between their ammonium groups and the anionic groups of the hair the cationic active polymers have a great affinity with respect to the keratine fiber.
It had been found that the use of such cationic active polymers in such agents results in numerous advantages; the disentanglement of the hair as well as the treatment of which is facilitated, and in furtherance the hair gets bounceability and a luster. However, due to the affinity to the keratine the polymers tend to collect on the hair during frequent use, so that the hair becomes heavier which in the final analysis is undesireable.
As had been shown in practice in accordance with the state of the art these approaches are not fully satisfactory with respect to their hair conditioning effect, in particular concerning the touch, luster as well as the combability of the hair.
In contrast thereto, it now had been found that hair treatment agents in form of an ethanolic and/or isopropanolic solution with a content of a combination of improvement of the wet and dry combability of the hair as well as an improved touch in particular of damaged hair. Moreover, an excellent luster of the hair is noticeable.
The excellent noticeable improvement of the combability, the luster and the touch is surprising and can only be synergistically explained, since cetyllactate or quaternary monomer ammonium compounds in a corresponding solution applied alone to the hair results merely in a moderate and insufficient improvement of the mentioned criteria. As tests have shown the combination of cetyllactate with quaternary polymers does not show the synergystic noticeable effect with respect to the described improvement of the combability, the luster and the touch of the hair, in contrast to the agents in accordance with the invention on the basis of cetyllactate and monomer quaternary ammonium c
