Abstract

The present application directed to a unique combination of surfactants in concentrated form. In particular certain combinations of alkyl polyglucosides and polyglyceryl fatty acid esters when combined yield a cleansing concentrate which can be diluted to form tear free or mild cleanser.

First claim

The invention claimed is:

1. A cleansing concentrate comprising a stable dispersion of surfactants in water, the dispersion including nonionic surfactants in an amount that exceeds 40 wt. % and that comprises
a) about 10 to about 25 wt. % polyglycerine partial esters, wherein the partial esters are C 8 to C 22 ;
b) about 25 to about 50 wt. % alkyl polyglucoside; and
c) a hydrophobic emollient that is a fatty acid ester of glycerin that is different than component a), wherein the fatty acid ester of glycerin is a mono ester of glycerin selected from the group consisting of glyceryl mono laurate, glyceryl mono myristate, glyceryl mono stearate, glyceryl mono behenate, glyceryl mono palmitate, glyceryl mono palmitoleate, glyceryl mono oleate, glyceryl mono linolate, and mixtures thereof;
with the proviso that the concentrate contains less than 70 wt. % water and all weight percents are based on a total weight of the concentrate.

2. The cleansing concentrate according to claim 1 , wherein the polyglycerine partial esters are selected from the group consisting of polyglyceryl-4 caprylate/caprate, polyglyceryl-10 caprylate/caprate and polyglyceryl-4 caprate.

3. The cleansing concentrate according to claim 1 , wherein the alkyl of the alkyl polyglucoside is a C 8 to C 16 alkyl group, and, wherein the polyglucoside of the alkyl polyglucoside has an average degree of polymerization ranging from about 1 to 4.

4. A method of producing a personal cleansing formula that results in reduced irritancy to an individual's eyes when the personal cleansing formula comes into contact therewith, the method comprising adding nonionic surfactants in an amount that exceeds 40 wt. % to a composition that comprises
a) about 10 to about 25 wt. % polyglycerol partial ester;
b) about 25 to 50 wt. % of alkyl polyglucoside; and
c) a hydrophobic emollient that is a fatty acid ester of glycerin that is different than component a), wherein the fatty acid ester of glycerin is a mono ester of glycerin selected from the group consisting of glyceryl mono laurate, glyceryl mono myristate, glyceryl mono stearate, glyceryl mono behenate, glyceryl mono palmitate, glyceryl mono palmitoleate, glyceryl mono oleate, glyceryl mono linolate, and mixtures thereof;
wherein the wt. % is based on the total weight of the personal cleansing formulation and the partial esters are C 8 to C 22 .

5. The method according to claim 4 , wherein the personal cleansing formulation comprises no additional surfactants other than the polyglycerol partial ester and the alkyl polyglucoside.

6. The method according to claim 4 , wherein the polyglycerol partial esters are selected from the group consisting of polyglyceryl-4 caprylate/caprate, polyglyceryl-10 caprylate/caprate and polyglyceryl-4 caprate.

7. The method according to claim 4 , wherein the alkyl of the alkyl polyglucoside is a C 8 to C 16 alkyl group, and wherein the glucoside of the alkyl polyglucoside has an average degree of polymerization ranging from about 1 to 4.

8. The method according to claim 4 wherein the alkyl polyglucoside is decyl glucoside.

9. The method according to claim 4 , further comprising:
diluting the personal cleansing formula with an aqueous solution to produce a baby wash formulation.

10. The method according to claim 9 , wherein the personal cleansing formula is diluted with the aqueous solution such that an amount of the personal cleansing formula accounts for about 18 to 20 wt % of a total weight of the baby wash formulation.

11. A baby wash formulation formed according to a method comprising:
diluting the cleansing concentrate of claim 1 with an aqueous solution.

12. The baby wash according to claim 11 , wherein the cleansing concentrate is diluted with the aqueous solution such that an amount of the cleansing concentrate accounts for about 18 to 20 wt % of a total weight of the baby wash formulation.
