DESCRIPTION:
BRIEF SUMMARY
The subject of the present invention is cosmetic and/or soap products containing substances of milk origin, that is to say ingredients derived from whole or skimmed milk or extracts from milk. The invention is also concerned with the preparation of such products.
The favourable effect of milk or products derived from milk on cosmetic compositions, such as lotions for the skin, hair lotions, shampoos, softening creams, and soaps, is well known, and numerous compositions containing such ingredients have been described in the state of the art.
Thus, the document U.S. Pat. No. 3,959,491 describes cosmetic creams and lotions containing sterilized milk and milk cream. To improve the preservation of such products in storage, this document recommends incorporating into the cosmetic compositions saturated fatty acids, triglyceride esters of saturated fatty acids, stabilising aliphatic diols, sequestering agents and biocidal agents, in particular enzyme denaturants and bactericides. Of course, apart from the preservation agents above, the cosmetics described in this document contain the usual constituents of cosmetics, including perfumes, opacifiers and others.
The document DD-A-112,351 (East Germany) describes cosmetic products containing an active complex derived from milk or whey constituents, in particular non-denatured proteins, vitamins and constituent salts of milk. According to a process for preparation of such an active complex as described in this document, a mass of whey is subjected to concentration under reduced pressure followed by centrifuging and, finally, drying by atomization. For the manufacture of cosmetics, proportions of the order of 10-20% of the active complex such as prepared as described are added to the cosmetics.
The document U.S. Pat. No. 4,460,571 describes a cosmetic on a base of whole or powdered milk which particularly lends itself to topodermic and capillary uses. In this, there are in question fluid compositions, antiseptic and perfumed compositions containing skimmed milk or non-skimmed milk, or containing dissolved powdered milk, and, apart from water and the usual ingredients of such lotions, quite a high proportion of alcohol.
The document GB-A-2,056,854 describes cosmetics, in particular lotions and shampoos, containing, apart from the normal ingredients inherent in such products, very high proportions of milk (40-80%) and, as a stabilising agent, propylene glycol.
The document GB-A-2,051,076 describes a process for preparation of moisturizing agents useful in the field of cosmetics, these agents being derived by fermentation from skimmed milk.
More precisely, this document describes the formation of water soluble casein hydrolysates by the action of lactic ferments and proteases. These hydrolysates, colourless and transparent, are then incorporated, at levels of 0.1 to 10% by weight, into cosmetics, in particular softening lotions for the skin, creams, and soapstuff products, etc., in such a manner as to confer, on these cosmetics, improved properties in respect of softening power, prevention of drying out of the skin, and maintaining its elasticity.
The document GB-A-2,037,160 describes a lyophilised product derived from milk having advantagous cosmetic properties, in particular for moisturizing and softening of the skin along with its regeneration. Such a product contains principally lactose, milk proteins, and water. It is obtained by fermentation of skimmed milk or non-skimmed milk by means of enzymes and milk ferments, in particular pancreatin, pepsin, and the ferments Lactobacillus bulgaricus and Streptococcus thermopilus. The fermented product is then lyophilised and used, in a mixture, with cosmetic compositions to improve their properties.
The document DE-A-2,623,250 describes cosmetic compositions containing milk. Among these, there are mentioned shampoos, beauty lotions, shaving creams, creams for the skin, etc. All these products have in common, apart from milk and water, surfactant substances, such as alkyl-sulphonates, sulphonated fatty acids, and the salts of t
