Abstract

A dispensable hydroalcoholic gel composition is provided. The dispensable hydroalcoholic gel includes a C 1-4 alcohol, a polyacrylate thickener, and a glyceryl ester.

Claims (26)

1. A dispensable hydroalcoholic gel composition consisting of:

at least 50 wt. % of a C 1-4 alcohol, based upon the total weight of the hydroalcoholic gel composition;

from about 0.01 to about 10 wt. % of a polyacrylate thickener, based upon the total weight of the dispensable gel composition;

a glyceryl ester;

one or more humectants;

one or more moisturizing esters;

one or more additives selected from the group consisting of: antioxidants, botanicals, colorants, fragrance components, sunscreen agents, and ultraviolet light absorbers; and

water.

2. The composition of claim 1 , wherein the C 1-4 alcohol is selected from the group consisting of ethanol, propanol, isopropanol, butanol, isobutanol, tertiary butanol, methanol, and mixtures of any two or more thereof.

3. The composition of claim 1 , wherein the polyacrylate thickener is selected from the group consisting of acrylates/C10-30 alkyl acrylate crosspolymers, copolymers of acrylic acid and alkyl C5-C10 acrylate, copolymers of acrylic acid and maleic anhydride, carbomers, and mixtures of any two or more thereof.

4. The composition of claim 1 , wherein the glyceryl ester comprises monoesters, di-esters, tri-esters, or a mixture of any two or more thereof.

5. The composition of claim 1 , wherein the dispensable hydroalcoholic gel composition comprises about 0.005 to about 4 weight percent glyceryl ester, based upon the total weight of the dispensable gel composition.

6. The composition of claim 1 , wherein the dispensable hydroalcoholic gel composition comprises about 0.01 to about 1 weight percent glyceryl ester, based upon the total weight of the dispensable gel composition.

7. The composition of claim 1 , wherein the one or more humectants are selected from the group consisting of propylene glycol, dipropyleneglycol, hexylene glycol, 1,4-dihydroxyhexane, 1,2,6-hexanetriol, sorbitol, butylene glycol, propanediol s, dipropylene glycol, triethylene glycol, glycerin, polyethylene glycols, ethoxydiglycol, polyethylene sorbitol, and combinations thereof.

8. The composition of claim 1 , wherein the one or more moisturizing esters are selected from the group consisting of cetyl myristate, cetyl myristoleate, diisopropyl sebacate, and isopropyl myristate.

9. A dispensing device comprising a reservoir, a pump, and an outlet, said reservoir containing a dispensable hydroalcoholic gel composition, wherein the dispensable hydroalcoholic gel composition consists of:

at least 50 wt. % of a C 1-4 alcohol, based upon the total weight of the hydroalcoholic gel composition;

from about 0.01 to about 10 wt. % of a polyacrylate thickener, based upon the total weight of the hydroalcoholic gel composition;

an additive comprising a glyceryl ester, wherein said additive prevents the dispensable hydroalcoholic gel composition from producing mis-directed output when dispensed from the dispensing device;

one or more humectants;

one or more moisturizing esters;

one or more additives selected from the group consisting of: antioxidants, botanicals, colorants, fragrance components, sunscreen agents, and ultraviolet light absorbers; and

water.

10. The dispensing device of claim 9 , wherein the C 1-4 alcohol is selected from the group consisting of ethanol, propanol, isopropanol, butanol, isobutanol, tertiary butanol, methanol, and mixtures of any two or more thereof.

11. The dispensing device of claim 9 , wherein the polyacrylate thickener is selected from the group consisting of acrylates/C10-30 alkyl acrylate crosspolymers, copolymers of acrylic acid and alkyl C5-C10 acrylate, copolymers of acrylic acid and maleic anhydride, carbomers, and mixtures of any two or more thereof.

12. The dispensing device of claim 9 , whereby the dispensable hydroalcoholic gel composition exhibits at least 50% less misdirection during dispensing from said dispenser than a gel composition that is substantially similar to said dispensable hydroalcoholic gel composition, but for the presence of said additive.
