Abstract

The invention relates to hydrous liquid paste or cream-like hand cleansing agents without organic solvents, especially a course hand cleanser with a rubbing agent. Said cleansing agents are characterized by a content of 10 to 30 wt. % of at least one vegetable oil from the group of triglycerides, saturated and/or unsaturated fatty acids, of 10 to 30 wt % of a tenside comprised of a fatty alcohol ethoxylate, at least one fatty alcohol ether sulfate and/or a salt of a sulfonated fatty acid, 10 to 65 wt. % water, each referring to the composition of the cleansing agent, and optionally 1 to 30 wt. % of at least one abrasive. In addition, the hand cleanser optionally contains at least one viscosity building agent and optional additional cosmetic auxiliary, accessory and/or active agents.

Claims

1. A hydrous, liquid, pasty or creamy hand cleansing agent, which does not contain any organic solvent and comprises:

(a) 10-30 wt.-%, relative to the composition of the hand cleansing agent, of one or more vegetable oils selected from the group consisting of triglycerides and saturated and/or unsaturated fatty acids;

(b) 10-30 wt.-%, relative to the composition of the hand cleansing agent, of a surfactant composition containing;

(α

) at least one fatty alcohol ethoxylate,

(β

) at least one fatty alcohol ether sulfate, and

(γ

) at least one salt of a sulfurated fatty acid;

(c) 10-65 wt.-% of water, relative to the composition of the hand cleansing agent;

(d) optionally, 1-30 wt.-%, relative to the composition of the hand cleansing agent, of one or more abrasives;

(e) optionally, one or more viscosity-building agents; and

(f) optionally, further cosmetic adjuvants, additives and/or active substances;

wherein the sum of components (a) through (f) is 100 wt.-%, and wherein the content of component (a) is higher or equal to the content of fatty alcohol ethoxylates (α

), and the content of fatty alcohol ethoxylates (α

) is higher or equal to the content of the two components (β

) and (γ

) in the composition of the hand cleansing agent.

2. The hand cleansing agent according to claim 1, wherein the triglycerides have an elevated percentage of unsaturated fatty acids.

3. The hand cleansing agent according to claim 1, wherein the surfactant composition (b) contains:

fatty alcohol ethoxylates represented by the formula;

4. The hand cleansing agent according to claim 3, wherein (b) comprises laureth-6, sodium lauryl ether sulfate and sodium or ammonium castor oil sulfonate.

5. The hand cleansing agent according to claim 1, wherein the surfactant composition (b) is comprised of 5-28 wt.-% of (α

), 1.9-15 wt.-%, of (β

) and 0.1-10 wt.-% of (γ

), wherein the sum of components (α

) through (γ

) is 10-30 wt.-%.

6. The hand cleansing agent according to claim 1, wherein the abrasives are plastic abrasive agents based on polyethylene or polyurethane or abrasive agents based on natural kernel and/or shell meals.

7. The hand cleansing agent according to claim 6, wherein the abrasives are H₂O₂-bleached meal of walnut shells orjojoba wax beads.

8. The hand cleansing agent according to claim 1, wherein the viscosity-building agents are selected from the group consisting of organophilic and/or hydrophilic layer silicates, polysaccharides, modified polysaccharides, and inorganic electrolytes.

9. The hand cleansing agent according to claim 1, wherein the cosmetic adjuvants, additives and/or active substances are selected from the group consisting of pH regulators, odorous substances, preservatives, preferably organic acids, and antioxidants.

10. The hand cleansing agent according to claim 1, wherein

(a) comprises colza oil,

(b) comprises a mixture of laureth-6, sodium laureth sulfate and castor oil sulfonate as component b),

(d) comprises bleached walnut shell meal as component d),

(e) comprises bentonite, carboxymethylcellulose and sodium chloride as component e), and

(f) comprises citric acid, preservatives, vitamin E acetate, and perfume.
