Description

"Nourishing cosmetic cleanser with improved foam properties"

The invention is in the field of cosmetics and relates to detergents which contain a specific surfactant mixture in a certain ratio, a sorbitan acid ester and a nonionic cellulose ether.

Cosmetic cleansers for the skin and / or the hair such as liquid soaps, shampoos, shower baths, bubble baths and shower and wash gels must have a good skin and / or mucous membrane compatibility in addition to the cleaning, and must not lead to damage to the skin barrier even with frequent use to lead.

Therefore, modern detergents often contain additional care components, such as cationic polymers, so-called moisturizing components and / or lipid replenishers, in order to bring the moisture content of the skin (the scalp) as little as possible out of its natural balance.

In addition to the incorporation of additional care components, efforts are being made to combine these with particularly mild surfactant mixtures.

In the publication WO 2007/006402, mild detergents with improved foaming and foaming properties are disclosed which comprise a combination of

a) anionic sulfuric esters,

b) amphoteric surfactants and

c) contain> 1, 2 wt .-% ethoxylated glycerol fatty acid esters having 3 to 12 ethylene oxide units, wherein the total surfactant content (a), b), c) and optionally other surfactants) <16 wt .-% is.

The compositions are mild. However, it could be observed that the foam stability of the agents was not always satisfactory.

In the patent application EP 1422288 liquid soaps are improved with

Foam properties containing a combination of at most 10 wt .-% of anionic and amphoteric surfactants, alkali soaps and nonionic cellulose ethers.

The liquid soaps provide a rich, fast-forming, creamy lather that easily rinses off the skin. However, the amount of foam that formed was unsatisfactory.

There is therefore still a need for mild cosmetic cleaners with excellent cleansing properties, good foaming power and good foaming properties.

The object of the present invention was to produce particularly mild cosmetic cleansing preparations with very good care performance and skin tolerance. The cleaning agents should continue to have excellent foam properties.

The foam should be well spreadable and stable on the skin. He should also be easy on the

Rinse skin again and leave a tension-free skin feeling.

They are particularly good on the skin and provide a particularly stable, creamy

Foam that develops quickly and spreads well on the skin. After the rinse, the foam leaves a pleasant, tension-free skin feeling.

The texture of the cleaning agents according to the invention is particularly rich.

Foaming properties, cleaning and care) already from a total surfactant content of only 14

% By weight can be formulated. The production of particularly sensitive compositions is therefore possible.
