Description

The purpose of cosmetic skin care is to maintain the normal texture of the skin. Therefor a large number of preparations have been developed to which various functions

A large part of them are the cosmetic bath preparations, which are essentially for The healthy body and body care are intended in a narrower sense, but they are also can have a stimulating effect on the entire metabolism, increase general well-being and also light skin-functional; Eliminate malfunctions or are able to reduce. First and foremost, however, they are intended to enhance the cleansing properties of the water and the soap by softening the water and, for example, by adding essential oils and aromatic substances, the feeling of well-being convey. Not hot · of the cosmetic bath preparations are the,, medicinal preparations too separate. Both groups merge into one another in terms of form and tasks. But this is especially important to them Task to stimulate the metabolism of the diseased body or the To influence the skin favorably.

Experience has now shown that the active ingredients and surface-active ingredients incorporated into the preparations In many cases, detergents have a very undesirable effect on degreasing the surface of the skin Have consequence. Attempts have been made to counteract this by adding additives. It is Z. B. the Article "The production of foam baths" in Seifen, Öle, Fette, Wachse (1963), p. 899, can be found, that a sulfosuccinic acid half-ester, an ethoxylated alkylolamide, is added to a bubble bath clogs. E. Scott Pattison describes in "Industrial Fatty Acids and their application" on Pages 114 to 123 describe the use of polyoxyethylene monolaurate in creams, lotions and hairdressings. In Fette, Seifen, Anstrichmittel (1965), p. 517, are also esters, namely fatty acid polyglycol esters as Called overfat.

So far, no agent was known which could be used in various cosmetic and medicinal preparations; which are present both in aqueous and in oily form, enables. In Such a product must have hydrophilic residues that cause water solubility, as well as hydrophobic ones There are residues that allow the desired fatty film to form on the skin, without that this can be washed away again by water.

It has been found that cosmetic and medical preparations have lipid replenishing properties, if you give them partial glyceride mixtures of saturated vegetable acids with 8 to 14 carbon atoms adds, on the free OH groups of the glycerol each 2 to 8 mol, preferably 4 to 8 mol, in particular 5 moles of ethylene oxide are deposited, and that these products are both successful with oily as well as aqueous preparations can be used.

Such a partial glyceride mixture used for ethoxylation has roughly the following key figures:

Acid number about 1

Saponification number 250

Iodine number below 1

Hydroxyl number 370

Monoester content 42%

The best products have proven to be those to which 5 moles of ethyleneoxy have been added ^{to the pr: free OH group of the glycerol.}

With the addition of these funds, the ^! Various bath preparations are produced which, in addition to the cleansing properties, also have the above-described greasy effect on the skin. It could also be 10 to 50% of such agents in the various cosmetic preparations such. B. Skin milk

Claims (1)

Claim: Lipid-replenishing cosmetic and medical preparations, characterized by a content of partial glyceride mixtures of saturated vegetable fatty acids with 8 to 14 carbon atoms, on the free OH groups of the glycerol each 2 to 8 mol, preferably 4 to 8 mol, in particular 5 moles of ethylene oxide are deposited.
