Description

AGENT FOR HAIR TREATMENT, THICKENING, WHICH CONTAINS SOLUBLE GLASS DESCRIPTION OF THE INVENTION The object of the invention is an agent for the treatment of hair, in a thick form, based on water, containing at least one polymeric gel former, which comprises acid groups, water glass in a sufficient quantity for the partial or complete neutralization of the acidic groups of the polymeric gel former, and at least one hair-fixing polymer. Hair gels are used to provide human hair with fixation and consistency. The usual hair gels usually contain a combination of gel formers and polymers that fix the hair. The hair-fixing cosmetic polymers commonly used for these purposes show good fixing properties in aqueous, alcoholic or aqueous-alcoholic media, which after use keep in shape and fix the hair with more or less strength. In the case of the gel formers usually used, it is often anionic polymers, that is, polymers comprising acid groups, the thickener effect being triggered in the aqueous systems by neutralization of the acid groups with Ref .: 172595 appropriate neutralization. The neutralization agents usually used usually do not allow great possibilities of variation as regards extraordinary consistencies of the product and the rheological properties. They often also have an unfavorable effect on other properties that are desired in a hair gel. They can have an undesirable influence on the fixability, on the properties of use such as, for example, the ability to distribute or the ability to integrate into the hair, the hair or the properties of the hair, such as shine or shine. Touch sensation, or by virtue of incompatibilities may prevent the use of other components otherwise desired. The neutralizing agents that are most often used in styling gels are organic amines or inorganic hydroxides. These have the disadvantage that they are easily volatile and have an undesired odor of their own, such as ammonia, ethanolamine or aminomethylpropanol (AMP), or the neutralizing agents influence the quality of the polymer film undesirably, for example. , ammonia or alkaline hydroxides such as sodium or potassium hydroxide. Then the films are often not flexible enough and the hair has an unnatural feel to the touch. In the case of using superior, non-volatile molecular amines, it is never possible to completely exclude an unwanted own odor due to contaminations with easily volatile amines conditioned by production. Some amines have irritating effects on the skin, insufficient color stability or may be contaminated with N-nitrosamines critical for health. Furthermore, a general difficulty consists in ensuring a sufficient stability of the desired viscosity even in the case of prolonged storage at elevated temperatures (for example, 40 to 50 ° C). One of the neutralizing agents that is most commonly used up to now is AMP, because it offers an acceptable compromise between positive and negative properties. But in the case of specifying AMP is a limitation in terms of the rheological properties, the consistency of the product and the properties of use in the hair. With AMP and similar neutralizing agents it is not possible to obtain without a major problem a fundamental variation of the consistencies of the product and the rheological properties. Therefore, there was the problem of finding an alternative neutralizing agent for styling gels based on anionic thickeners which, on the one hand, allows a wider possibility of varying the consistency of the product and on the other hand does not present or in any case the minimum possible previously mentioned disadvantages. The object consisted in particular of providing a gel for hair with the minimum possible of own odor that at the same time has good properties of use on the hair (capacity of distribution, fixation, definition of wicks, etc.) and additionally has extraordinary haptic and / or rheological properties, as attractive as possible. It was now discovered that this problem is solved by the use of water glass. In this aspect it is possible to use the water glass as the sole neutralizing agent or in combination with at least one additional neutralizing agent. The subject of the invention is a hair treatment agent having a content of (A) at least one polymeric gel former comprising acid groups, (B) water glass (C) at least one hair fixative polymer, and ( D) water, the hair treatment agent being present in the form of a thickened preparation. The thickened preparation may have various consistencies, in particular as a gel, friable or in the form of pudding. The acid groups of the polymer gel former (A) are at least partially neutralized, preferably completely by the water glass. Solid glass is the designation for the glassy potassium and / or sodium silicates that solidify from the melting current (salts of silicic acids) or for its viscous aqueous solutions. In the water glass there are 2 to 4 molecules, of Si02 per 1 molecule of alkaline oxide, so the sodium and potassium silicate are usually also characterized by the ratio of mass or molar Si0 / alkaline oxide as well as by the density of the aqueous solution. Due to the hydrolysis they mainly contain hydrogen salts such as M3HSi04, M2H2Si04 and MH3Si04 (with M = K or Na). The purely soluble glasses are transparent, colorless glasses, as technical products with a blue to green or also yellowish to brown color by means of steel traces, which at high temperature and pressure form clear, strongly alkaline, colloidal solutions with water. Soluble glass can be produced by fusing together quartz sand with sodium or potassium carbonate at 1400-1500 ° C, thereby releasing C02. The solidified melt is sold either in the ground state or in the form of aqueous solutions with the desired concentration. Sodium silicate is preferred according to the invention.
