Abstract

Sweat-absorbing complex comprises at least one sheet silicate which is modified with at least one quaternary ammonium compound, and at least one further component comprising an oily extract of the sprouts of Bambusa vulgarisand lignocellulose. An independent claim is included for a cosmetic composition comprising 0-7 wt.% of free water, at least a liquid cosmetic oil under normal conditions, at least one antiperspirant aluminum salt, and the sweat-absorbing complex in a total amount of 1-10 (preferably 3-5) wt.%, without taking into account possible presence of a blowing agent.

Description

The present application is concerned with substantially anhydrous cosmetic compositions, especially deodorants and antiperspirants containing an antiperspirant aluminum salt and a novel perspiration-absorbing complex.

Antiperspirant or antiperspirant compositions are an important part of daily personal hygiene. They should ensure that the sweat production is reduced and formed sweat does not lead to unpleasant body odor. Sweat-inhibiting active ingredients, in particular based on aluminum salts, are already known in the prior art. The sweat reduction by aluminum salts is usually in the underarm area at 20-40%. Highly sweaty consumers want better effective products. Antiperspirants with very high doses of aluminum chlorohydrate may show unfavorable skin compatibility. Highly effective aluminum-zirconium compounds or aluminum chloride have a very low pH and therefore irritate the skin. Highly effective antiperspirant active ingredients usually lead to irreversible textile soiling. Highly effective antiperspirant active ingredients with zirconium are characterized by high and still sharply rising raw material costs. Consumers want antiperspirant preparations with natural ingredients.

Sweat absorbing complexes with gum are in US 2009/0087396 shown. Although the disclosed compositions have the desired absorbent properties, they are very tacky to the touch, feel slippery after absorption, and are difficult to remove from the skin.

EP 1281387 A1 discloses a plant-based antiperspirant cosmetic comprising a mixture of propylene glycol extracts of the above-ground plant parts of field horsetail (Equisetum arvense), Hamamelis virginia and Gall oak (Quercus infectoria), furthermore essential sage oil and powdered bamboo wood (bamboo powder) Particle size ≤ 15 microns contains. Furthermore, in the prior art antiperspirant compositions are known which contain as moisture absorbers so-called super-absorber polymers, for. B. WO 2003/030853 A1 , The object of the present application was to provide an antiperspirant cosmetic composition which has a very good antiperspirant performance, but at the same time is very well tolerated by the skin and exhibits minimal textile soiling and has a pleasant skin feel. Another object was to provide a antiperspirant cosmetic composition which achieves a very good antiperspirant performance with economically most favorable raw materials. Another object was to provide an antiperspirant cosmetic composition with pleasant sensory properties, which achieves a very good antiperspirant performance with natural ingredients.

Surprisingly, it has been found that the stated object is achieved by essentially anhydrous compositions containing a sweat-absorbing complex consisting of A) at least one layered silicate modified with at least one quaternary ammonium compound and B) an oil-soluble extract from the sprouts of bamboo vulgaris by anhydrous compositions containing a sweat-absorbing complex consisting of A) at least one layered silicate modified with at least one quaternary ammonium compound and B) lignocellulose.

These sweat-absorbing complexes can be used particularly advantageously in anhydrous antiperspirants with a moderate content of aluminum salts (5-17% by weight). Such compositions provide an extremely dry skin feel and excellent protection against perspiration. In addition, they are excellent skin-friendly and have compared to conventional antiperspirants on aluminum and zirconium basis lower formula costs. Also, the compositions of the invention leave little residue and no textile soiling, such as yellow spots. The raw materials of the absorber complex, phyllosilicates and bamboo shoot extract or lignocellulose are of natural origin.

All information on the states of aggregation of the starting materials used (solid, liquid ...) in this application are based on normal conditions.
