Methods and compositions for use with gel dispensers
A dispensable hydroalcoholic gel composition is provided. The dispensable hydroalcoholic gel includes a C 1-4 alcohol, a polyacrylate thickener, one or more neutralizers, and an additive. The dispensable hydroalcoholic gel exhibits less misdirection during dispensing from a dispensing device than gel compositions that are otherwise identical, but for the presence of the additive.
1. A dispensable hydroalcoholic gel composition comprising:
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;
one or more neutralizers selected from the group consisting of sodium hydroxide, ammonium hydroxide, potassium hydroxide, arginine, tetrahydroxypropyl ethylenediamine, triethanolamine, tromethamine, and triisopropanolamine; and
an additive comprising a C 6-10 alkane chain and at least two hydroxyl groups, whereby the dispensable hydroalcoholic gel composition exhibits less misdirection during dispensing from a dispensing device than a gel composition that is identical to said dispensable hydroalcoholic gel composition, but for the presence of said additive.
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 thereof.
3. The composition of claim 1 , wherein the polyacrylate thickener is selected from the group consisting of acrylates/C 10-30 alkyl acrylate crosspolymers, copolymers of acrylic acid and alkyl C 5 -C 10 acrylate, copolymers of acrylic acid and maleic anhydride, carbomers, and mixtures thereof.
4. The composition of claim 1 , wherein the composition further comprises at least one conditioning or moisturizing esters.
5. The composition of claim 1 , wherein the composition further comprises at least one antioxidant.
6. The composition of claim 1 , wherein the composition further comprises at least one humectant.
7. The composition of claim 1 , wherein the composition further comprises at least one viscosity increasing agent in addition to said polyacrylate thickener.
8. The composition of claim 1 , wherein the additive is selected from the group consisting of 1,2-octanediol, 1,2-hexanediol, 1,9-nonanediol, 1,2-decanediol, 1,10-decanediol, and mixtures thereof.
9. The composition of claim 1 , wherein the one or more neutralizers consists of tetrahydroxypropyl ethylenediamine.
10. The composition of claim 1 , wherein the one or more neutralizers provides a pH in the hydroalcoholic gel composition of from 4.5 to 9.5.
11. A dispensing device comprising a reservoir, a pump, and an outlet, said reservoir containing a dispensable hydroalcoholic gel composition comprising:
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;
one or more neutralizers selected from the group consisting of sodium hydroxide, ammonium hydroxide, potassium hydroxide, arginine, tetrahydroxypropyl ethylenediamine, triethanolamine, tromethamine, and triisopropanolamine; and
an additive comprising a C 6-10 alkane chain and at least two hydroxyl groups, wherein said additive prevents the dispensable hydroalcoholic gel composition from producing mis-directed output when dispensed from the dispensing device.
