^M Preparations for the manufacture of personal care products ¹¹

The invention relates to preparations for manufacture -of personal care products that contain amino acids or protein hydrolysates as active ingredients.

They use amino acids as an ingredient in skin care products is after "Perfumery and Cosmetics", Fr. 1, 1958, pages 11-15 already known. This is where you take action based on amino acids obtained by fractional hydrolysis of various naturally occurring proteins receives. In the German Auslegesehrift 1 035 855 the use of I-acylaminoic acids or inorganic ones or organic salts of F-acylamino acid esters as an additive to skin and hair care products furthermore, in the German patent specification 1 025 101 additions of reducing sugars together with amino acids Suggested in aqueous medium to skin care and skin protection agents. However, such additives develop as a result from oxidative or hydrolytic degradation certain unpleasant smells, which after longer storage a corresponding Use no longer allow. When using protein hydrolysates, the composition of the Preparations due to the absence of essential amino acids not optimal.

It has now been found that high quality, stable preparations that even after a long period of storage show no development of any kind, if one receives such used to prevent precipitation and oxidative changes in amino acids or protein hydrolysates

The stabilizing agent contains oystine dimethyl ester, Qljoln ttthyleeter and eXutamina & urediethyleeter.

Ala amino acids can be used in the preparations according to the invention GFlyoin, Alanine, Valine, Leuein, Iaoleuoin, Threonine, Aapartic acid, glutamic acid, arginine, Lyein, Ozy-IyBin, Oyatin, oyetein, methionine, hlatidine, proline, oxyproline, Phenylalanine, tyrosine, tryptophan, etc. contain aein. Although amino acids are generally one more or more have less good oil quality, but bind aie in pure ethanol insoluble and in high concentrated ethanol also insoluble or only very slightly soluble, as indicated in the following Table I, for example, with regard to a series of amino acids.

Binary personal care products, see B. Hair tonics or lotions, ■ however mostly represent ethanol solutions, in which The components of such care products are stable in the form of door beds in buses.

The preparations according to the invention for production of personal care products contain only one or more of the above amino acids in a stable dissolved state la äthanoliaoher solution, with the loops mentioned Stabilizing agents prevent precipitation and oxidation.

The Gruntlöeung for the production of the inventive Personal care products contain one or more of the amino acids just mentioned and the amine acid meter stabilizers mentioned dissolved in a stable state in Xthanol in a concentration τοη more than 90 Jt »whereby the Consentrations of some of the indicated amnosäuxtsn essential are higher than the β in common amine acid solutions is possible in Xthanol.

I am according to the invention personal care products can easily through Add a suitable amount of the Aino acid round solution can be made from any suitable ethanol solution, which contains other ingredients that are necessary for use as a personal care product.

The personal care products according to the invention can maturliea also by separately dissolving the desired amino acids and the other useful components in an ethanol Solution can be prepared which contains the same stabilizers as above.

The following examples serve to illustrate practical personal care products according to the invention. Unless otherwise noted, you understand the information in the examples on the basis of weight percent.
