Abstract

The invention is a cosmetic or dermatological cloth, comprising a water-insoluble nonwoven material, which is moistened with a cosmetic or dermatological impregnating solution comprising an oil-in-water emulsions having a viscosity of less than 2000 mPa·s and comprising one or more partially neutralized glyceride esters selected from the group consisting of monoglyceride and diglyceride esters of saturated fatty acids with citric acid and one or more fatty alcohols selected from the group consisting of branched and unbranched alkyl alcohols with 12 to 40 carbon atoms.

Claims (30)

1. A cloth, comprising a water-insoluble nonwoven, which has been moistened with an impregnation solution comprising an oil-in-water emulsion having a viscosity of less than 2000 mPa·s, and comprising:

one or more partially neutralized glyceride esters selected from the group consisting of monoglyceride and diglyceride esters of saturated fatty acids with citric acid and

one or more fatty alcohols selected from the group consisting of branched and unbranched alkyl alcohols with 10 to 40 carbon atoms.

2. The cloth as claimed in claim 1 , wherein the weight ratio of the unimpregnated cloth to the impregnation solution is from 1:1 to 1:5.

3. The cloth as claimed in claim 1 , wherein the one or more partially neutralized glyceride esters include glyceryl stearate citrate.

4. The cloth as claimed in claim 1 , wherein the one or more fatty alcohols include cetyl alcohol, stearyl alcohol, or a mixture thereof.

5. The cloth as claimed in claim 1 , wherein the one or more fatty alcohols include cetyl stearyl alcohol.

6. The cloth as claimed in claim 1 , wherein the total amount of the one or more partially neutralized glyceride esters in the impregnation solution is from 0.1 to 10.0% by weight, based on the total weight of the impregnation solution.

7. The cloth as claimed in claim 6 , wherein the total amount of the one or more partially neutralized glyceride esters in the impregnation solution is from 0.5 to 6.0% by weight, based on the total weight of the impregnation solution.

8. The cloth as claimed in claim 1 , wherein the total amount of the one or more fatty alcohols in the impregnation solution is from 0.1 to 10.0% by weight, based on the total weight of the impregnation solution.

9. The cloth as claimed in claim 1 , wherein the total amount of the one or more fatty alcohols in the impregnation solution is from 0.5 to 6.0% by weight, based on the total weight of the impregnation solution.

10. The cloth as claimed in claim 1 , wherein the weight ratio of the one or more partially neutralized glyceride esters to the one or more fatty alcohols is from 7:3 to 3:7.

11. The cloth as claimed in claim 10 , wherein the weight ratio of the one or more partially neutralized glyceride esters to the one or more fatty alcohols is from 2:1 to 1:2.

12. The cloth as claimed in claim 11 , wherein the weight ratio of the one or more partially neutralized glyceride esters to the one or more fatty alcohols is about 1:1.

13. The cloth as claimed in claim 1 , wherein the impregnation solution includes an oil phase and an aqueous phase, wherein the oil phase is present in the impregnation solution in an amount from 5 to 40% by weight, based on the total weight of the impregnation solution.

14. The cloth as claimed in claim 1 , wherein the impregnation solution further comprises one or more auxiliaries, additives or active ingredients selected from the group consisting of moisturizers, waxes, surfactants, preservatives, antioxidants, dyes, plant extracts, UV filters, pigments, deodorant and antiperspirant active ingredients, dermatological active ingredients and perfumes.

15. The cloth as claimed in claim 1 , wherein the oil-in-water emulsion comprises one or more fatty alcohols selected from the group consisting of branched and unbranched alkyl alcohols with 10 to 30 carbon atoms.

16. A cloth, comprising a water-insoluble nonwoven, which has been moistened with an impregnation solution comprising an oil-in-water emulsion having a viscosity of less than 2000 mPa·s, and comprising:

one or more partially neutralized glyceride esters selected from the group consisting of monoglyceride and diglyceride esters of saturated fatty acids with citric acid;

one or more fatty alcohols selected from the group consisting of branched and unbranched alkyl alcohols with 10 to 40 carbon atoms; and

one or more washing-acting surfactants having a HLB greater than about 25.

17. The cloth as claimed in claim 16 , wherein the amount of water in the impregnation solution is less than about 80.0% by weight, based on the total weight of the impregnation solution.

18. The cloth as claimed in claim 16 , wherein the weight ratio of the unimpregnated cloth to the impregnation solution is from 1:1 to 1:5.

19. The cloth as claimed in claim 16 , wherein the one or more partially neutralized glyceride esters include glyceryl stearate citrate.

20. The cloth as claimed in claim 16 , wherein the one or more fatty alcohols include cetyl alcohol, stearyl alcohol, or a mixture thereof.

21. The cloth as claimed in claim 16 , wherein the total amount of the one or more partially neutralized glyceride esters in the impregnation solution is from 0.1 to 10.0% by weight, based on the total weight of the impregnation solution.

22. The cloth as claimed in claim 16 , wherein the total amount of the one or more fatty alcohols in the impregnation solution is from 0.1 to 10.0% by weight, based on the total weight of the impregnation solution.

23. The cloth as claimed in claim 16 , wherein the weight ratio of the one or more partially neutralized glyceride esters to the one or more fatty alcohols is from 7:3 to 3:7.

24. The cloth as claimed in claim 16 , wherein the impregnation solution includes an oil phase and an aqueous phase, wherein the oil phase is present in the impregnation solution in an amount from 5 to 40% by weight, based on the total weight of the impregnation solution.

25. The cloth as claimed in claim 16 , wherein the impregnation solution further comprises one or more auxiliaries, additives or active ingredients selected from the group consisting of moisturizers, waxes, preservatives, antioxidants, dyes, plant extracts, UV filters, pigments, deodorant and antiperspirant active ingredients, dermatological active ingredients and perfumes.
