Description

Cosmetic preparations

The present invention relates to cosmetic preparations which contain yoghurt.

Yogurt is a popular food that has many valuable ingredients like protein, fat, and carbohydrates Contains vitamins. The usual commercial form is only chilled and can be kept for short periods of time. As far as is known, was Yoghurt has not yet been incorporated into cosmetic preparations.

It has now been found that the incorporation of yogurt into cosmetic preparations with the aid of stabilizing Components is possible and leads to durable preparations. This was by no means to be expected, because yogurt is made from Milk is made using specific fermentation agents and is also refrigerated and with the addition of sorbic acid only has a limited shelf life, so that its use as a component in cosmetic preparations is not readily possible. Surprisingly, however, when stabilizing components are added, long-lasting preparations are obtained that are consistent Quality.

For the preparations according to the invention, yogurt is used as Yoghurt powder (dry powder) or used as fresh produce. The stabilizing components are preservatives, Antioxidants, chelating agents (metal complexing agents) and proteinase inhibitors.

As preservatives, antioxidants and chelating agents, those described by H.P. Fiedler in Lexicon of Auxiliaries for Pharmacy, cosmetics and related areas, Edito Cantor KG, 1971 »are suitable. Examples of proteinase inhibitors are aprotinin, kallikreine and antipain.

The preparations according to the invention are used for external Application. They are used like the usual cosmetic products, namely as emulsions in solid and liquid Form, e.g. cream, milk, aerosols.

The preparations according to the invention are solid or liquid Emulsions of the type O / W (oil in water) or W / O (water in oil) as well as aerosol preparations. Yogurt is available as a dry powder or fresh product in concentrations up to 50%, preferably 5 to 15 & used.

The amount of preservatives used depends on the effectiveness of the substance itself and the respective basic and auxiliary materials. It is usually between 0.01 and 0.3%.

Antioxidants are used in amounts between 0.02 and about 0.5% added. Here, too, the active ingredient itself and the basis of the preparation determine the exact amount used.

The concentrations of the chelating agents should be between 0.05% and 0.5%, depending on the type.

Proteinase inhibitors are used in amounts of about 0.05 & up to 5.0% used.
