Temperature stable cosmetic cleaning preparation with dicarboxylic acids

The present invention relates to a liquid or pasty cosmetic cleaning preparation containing alkali soaps and dicarboxylic acids.

The desire for clean skin is probably as old as mankind, because dirt, sweat and residues of dead skin particles provide the ideal breeding ground for pathogens and parasites of all kinds. The oldest preparations for cleaning the skin are the soaps, the formulations of which are found on clay tablets 2500 B.C. from the two-stream country were mentioned. Even though the use and consumption of soaps has declined since the development of cleaning surfactants, they still have a firm place in the range of cosmetic cleaning preparations, not least because of their low manufacturing costs.

Soaps are formed during the reaction ("saponification") of a fat or of fatty acids or fatty acid methyl esters obtained therefrom with sodium hydroxide or potassium hydroxide solution, and chemically they represent the alkali salt of fatty acids.

Beef tallow, palm oil, palm kernel oil or coconut oil are usually used as neutral fats. The distribution of the chain lengths of the corresponding fatty acids is important for the properties of the soap. A high concentration of laurate soap (created from lauric acid = dodecanecarboxylic acid) leads to a particularly good foaming soap. The choice of the cation required for salt formation also influences the properties of the soap. Sodium soaps are mostly solid at room temperature, while potassium soaps generally have a soft and pasty consistency [W. Umbach (ed.): Cosmetics, development, production and use of cosmetic products, 2nd edition, Thieme Verlag, Stuttgart, 1995].

However, pasty and liquid soap-containing cleaning preparations of the prior art have a number of disadvantages. In particular, the temperature stability of such preparations leaves something to be desired. This leads to instabilities at elevated storage temperatures, usually in the form of a phase separation of the liquid and solid phases. The soap-forming fatty acids are usually mixtures of fatty acids that have different and relatively low melting points. Table 1 below provides an overview of the melting points of common fatty acids:

Tabelle 1: Schmelzpunkte von Fettsäuren

Table 1: Melting points of fatty acids

If the ambient or storage temperature is elevated, the individual fatty acids melt and there are differences in density in the liquid-viscous preparation and thus phase separation.

Soap-containing liquid or pasty cleaning preparations are particularly popular in South-East Asia, since the preparations leave a dry, clean feeling on the skin. Especially in the subtropical-tropical latitudes, the temperature stability of soap-containing cleaning preparations plays a special role.

It was therefore the object of the present invention to develop liquid to pasty cosmetic cleaning preparations which have a significantly higher temperature stability.

The object is surprisingly achieved by liquid or pasty cosmetic cleaning preparation comprising a) one or more alkali soaps, b) one or more compounds from the group of dicarboxylic acids, in addition to any other cosmetic or dermatological active ingredients, auxiliaries and additives.

According to the invention, liquid or pasty cleaning preparation means that the preparation has a viscosity of 800 to 10,000 mPas. The viscosity values of the preparations and individual substances listed in the context of the present specification were determined with the aid of a Viscotester VT 02 viscometer from Haake (temperature: 25 ° C., spindle diameter 24 mm, rotor speed 62.5 1 / min).
