Abstract

The present invention relates to the use of a polysaccharide selected from the group of non-modified polysaccharides, chemically modified polysaccharides and physically modified polysaccharides, in antiperspirant cosmetic agents, the use of these polysaccharides resulting in an excellent reduction and/or prevention of textile discoloration and/or textile stains.

First claim

What is claimed is:

1. A method for preventing and/or reducing textile discolorations and/or textile stains, wherein the method comprises the following method steps:
(a) producing an antiperspirant cosmetic agent by mixing an antiperspirant aluminum salt with at least one chemically modified polysaccharide and microcrystalline cellulose and optionally further ingredients and optionally propellants, wherein the antiperspirant aluminum salt is present in the cosmetic agent in an amount of 2 to 40 wt % based on the total weight of the cosmetic agent and the at least one chemically modified polysaccharide is present in an amount of 0.8 to 2.5 wt. % based on the total weight of the cosmetic agent;
(b) applying the antiperspirant cosmetic agent to the skin;
(c) wearing a piece of textile clothing over the treated skin; and
(d) washing the piece of textile clothing, wherein after washing, no textile discolorations, no textile stains, decreased textile discolorations as compared to the same method using an antiperspirant cosmetic agent without the at least one chemically modified polysaccharide, or decreased textile stains as compared to the same method using an equivalent antiperspirant cosmetic agent without the at least one chemically modified polysaccharide wherein the at least one chemically modified polysaccharide is selected from the group consisting of C 1-10 alkyl cellulose, hydroxy C 2-10 alkyl methyl cellulose, hydroxy C 2-10 alkyl ethyl cellulose, hydroxy C 1-10 alkyl cellulose, carboxy C 1-10 alkyl cellulose, and C 6-30 alkyl hydroxyethyl cellulose, and mixtures thereof.

2. The method of claim 1 , wherein the chemically modified polysaccharide includes chemically modified starches which are selected from the group consisting aluminum starch octenylsuccinate, sodium starch octenylsuccinate, calcium starch octenylsuccinate, dehydrated xanthan gum; and the mixtures thereof.

3. The method of claim 1 , wherein the chemically modified polysaccharide is selected from the group consisting of methylcellulose, hydroxyethyl cellulose, hydroxyethyl methyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl ethyl cellulose, carboxymethyl cellulose, and cetyl hydroxyethylcellulose.

4. The method of claim 1 , wherein the antiperspirant aluminum salt is selected from the group consisting of aluminum chlorohydrate, aluminum sesquichlorohydrate, aluminum dichlorohydrate, aluminum hydroxide, potassium aluminum sulfate, aluminum bromohydrate, aluminum chloride, aluminum sulfate; aluminum chlorohydrex propylene glycol, aluminum chlorohydrex polyethylene glycol, aluminum propylene glycol complexes, aluminum sesquichlorohydrex propylene glycol, aluminum sesquichlorohydrex polyethylene glycol, aluminum propylene glycol dichlorohydrex, aluminum polyethylene glycol dichlorohydrex, aluminum undecylenoyl collagen amino acid, sodium aluminum lactate, sodium aluminum chlorohydroxy lactate, aluminum lipoamino acids, aluminum lactate, aluminum chlorohydroxy allantoinate, sodium aluminum chlorohydroxy lactate; and aluminum-zirconium trichlorohydrate, aluminum-zirconium tetrachlorohydrate, aluminum-zirconium pentachlorohydrate, aluminum-zirconium octachlorohydrate; aluminum-zirconium propylene glycol complexes, aluminum-zirconium trichlorohydrex glycine, aluminum-zirconium tetrachlorohydrex glycine, aluminum-zirconium pentachlorohydrex glycine, aluminum-zirconium octachlorohydrex glycine; and the mixtures thereof.

5. The method of claim 1 , wherein weight ratio of the antiperspirant aluminum salt to the polysaccharide is from 40:1 to 19:1.

6. The method of claim 1 , wherein weight ratio of the antiperspirant aluminum salt to the polysaccharide is from 9:1 to 12:1.

7. The method of claim 1 , wherein the antiperspirant cosmetic agent further comprises at least one odorous substance a total amount of 0.00001 to 10 wt. % based on the total weight of the antiperspirant cosmetic agent.

8. The method of claim 1 , wherein the antiperspirant cosmetic agent further comprises at least one wax in a total amount of 0.01 to 20 wt. % based on the total weight of the antiperspirant cosmetic agent.

9. The method of claim 1 , further comprising 1 to 50 wt. % ethanol based on the total weight of the antiperspirant cosmetic agent.
