Abstract

The invention relates to a surfactant solution containing: (a) 28 to 65 wt.-% of a mixture of (a1) 5 to 20 wt.-% of N-methyl-N-oleylglucamine, (a2) 50 to 93 wt.-% of N-methyl-N—C 12 -C 14 -acylglucamines, (a3) 0 to 30 wt.-% of other N-methyl-N-acylglucamines, components (a1), (a2) and (a3) adding up to 100 wt.-%, (b) 0 to 20 wt.-% of one or more alcohols, (c) 20 to 72 wt.-% of water, and (d) 0 to 5 wt.-% of additives, components (a), (b), (c) and (d) adding up to 100 wt.-%.

First claim

The invention claimed is:

1. A surfactant solution consisting of
(a) 28% to 65% by weight of a mixture of
(a1) 5% to 20% by weight of N-methyl-N-oleylglucamine,
(a2) 50% to 93% by weight of N-methyl-N—C 12 -C 14 -acylglucamines,
(a3) 0% to 30% by weight of further N-methyl-N-acylglucamines,
where the sum total of components (a1), (a2) and (a3) is 100% by weight,

(b) 0% to 20% by weight of one or more alcohols,
(c) 20% to 72% by weight of water,
(d) 0% to 5% by weight of additives,
wherein the surfactant solution has a melting point of less than 40° C. and does not form a gel on dilution with water.

2. The surfactant solution as claimed in claim 1 , wherein component (b), is selected from the group consisting of ethanol, isopropanol, 1,2-propylene glycol, 1,3-propylene glycol and glycerol.

3. The surfactant solution as claimed in claim 1 , consisting of
(a) 30% to 65% by weight of a mixture of
(a1) 6% to 18% by weight of N-methyl-N-oleylglucamine,
(a2) 60% to 75% by weight of N-methyl-N—C 12 -C 14 -acylglucamines,
(a3) 10% to 30% by weight of further N-methyl-N-acylglucamines,
where the sum total of components (a1), (a2) and (a3) is 100% by weight,

(b) 3% to 17% by weight of one or more alcohols,
(c) 25% to 67% by weight of water,
(d) 0% to 2% by weight of additives.

4. The surfactant solution as claimed in claim 1 , which does not consist of any monoalcohol.

5. A cosmetic composition comprising a surfactant solution as claimed in claim 1 .

6. A process for producing cosmetic compositions, comprising the step of diluting the surfactant solution as claimed in claim 1 , with water and not forming a gel.

7. A composition consisting of
(A) 25% to 60% by weight of a mixture of
(a1) 5% to 20% by weight of N-methyl-N-oleylglucamine,
(a2) 50% to 95% by weight of N-methyl-N—C 12 -C 14 -acylglucamines,
(a3) 0% to 30% by weight of further N-methyl-N-acylglucamines,
where the sum total of components (a1), (a2) and (a3) is 100% by weight, as component (A),

(B) 0% to 10% by weight of one or more further surfactants as component (B),
(C) 0% to 20% by weight of one or more alcohols as component (C),
(D) 20% to 72% by weight of water as component (D),
(E) 0% to 5% by weight of further auxiliaries and additives as component (E).

8. The composition as claimed in claim 7 , consisting of
(a) 25% to 60% by weight of component (A),
(b) 1% to 5% by weight of component (B),
(c) 3% to 17% by weight of component (C),
(d) 25% to 65% by weight of component (D),
(e) 0% to 2% by weight of component (E).
