Abstract

The invention relates to the use of N-methyl-N—C 8 -C 14 -acylglucamines as solubilizers in cosmetic preparations. The invention further relates to clear lotions for the preparation of wet wipes, comprising a) 0.1 to 5.0 wt.-% of the N-methyl-N—C 8 -C 14 -acylglucamines, b) 0.05 to 5% of one or more water-insoluble or only partially water-soluble anti-microbial agents, c) 0 to 5 wt.-% of one or more oils, d) 85 to 99.85 wt.-% of water, e) 0 to 5 wt.-% of surfactants, and f) 0 to 5 wt.-% of additional auxiliaries and additives.

Claims (29)

1. A composition for producing wet wipes containing

a) 0.1 to 5.0% by weight of a mixture of N-methyl-N—C 8 -C 14 -acylglucamines wherein at least 80% by weight of the N-methyl-N-acylglucamines have a C 8 -C 10 acyl group,

b) 0.05 to 5% by weight of one or more water-insoluble or only partially water-soluble antimicrobial active ingredients selected from the group consisting of phenyoxyethanol, benzyl alcohol, phenethyl alcohol, 1,2-octanediol, ethylhexyl glycerol, sorbitan caprylate, glyceryl caprylate and parabens, provided that sorbitan caprylate is one of the ingredients,

c) 0 to 5% by weight of one or more oils,

d) 85 to 99.85% by weight of water,

e) 0 to 5% by weight of surfactants, and

f) 0 to 5% by weight of further auxiliaries and additives,

wherein the composition is in the form of a clear lotion, the lotion being optically transparent at a layer thickness of 5 cm.

2. The clear lotion as claimed in claim 1 , wherein it contains at least one oil selected from the group consisting of dicapryl ether, triglycerides of caprylic and/or capric acid and dicapryl carbonate.

3. A wet wipe which is impregnated with the clear lotion as claimed in claim 1 .

4. A process for producing the clear solution as claimed in claim 1 , comprising the step of adding to the clear solution a mixture of N-methyl-N—C 8 -C 14 -acylglucamines as a solubilizer.

5. The composition as claimed in claim 1 , wherein the total of components a) to f) is 100% by weight.

6. The composition as claimed in claim 1 , wherein the composition does not exhibit separation into a plurality of phases.

7. The composition as claimed in claim 1 , wherein b) is a combination of sorbitan caprylate, phenoxyethanol and benzyl alcohol.

8. A composition for producing wet wipes containing

a) 0.1 to 5.0% by weight of a mixture of N-methyl-N—C 8 -C 14 -acylglucamines wherein at least 80% by weight of the N-methyl-N-acylglucamines have a C 8 -C 10 acyl group,

b) 0.05 to 5% by weight of sorbitan caprylate,

c) 0 to 5% by weight of one or more oils,

d) 85 to 99.85% by weight of water,

e) 0 to 5% by weight of surfactants, and

f) 0 to 5% by weight of further auxiliaries and additives,

wherein the composition is in the form of a clear lotion, the lotion being optically transparent at a layer thickness of 5 cm.

9. The clear lotion as claimed in claim 8 , wherein it contains at least one oil selected from the group consisting of dicapryl ether, triglycerides of caprylic and/or capric acid and dicapryl carbonate.

10. A wet wipe which is impregnated with the clear lotion as claimed in claim 8 .

11. The composition as claimed in claim 8 , wherein the total of components a) to f) is 100% by weight.

12. The composition as claimed in claim 8 , wherein the composition does not exhibit separation into a plurality of phases.

13. The composition as claimed in claim 8 , wherein the sorbitan caprylate is present in an amount of 0.2 to 1.5% by weight.

14. The composition as claimed in claim 8 , wherein the sorbitan caprylate is present in an amount of 0.1 to 2% by weight.

15. The composition as claimed in claim 8 , wherein the total of components a) to f) is 100% by weight.
