6. The dispensable gel composition of claim 1 , wherein the diol plug-preventing additive is present in an amount of from 0.2 to 0.6 wt. %, based upon the total weight of the dispensable gel composition.
7. The dispensable gel composition of claim 6 , wherein the dispensable gel composition comprises at least 60 wt. % of said C 1-4 alcohol.
8. The dispensable gel composition of claim 7 , wherein the polyacrylate thickener is a carbomer.
9. A dispensable gel composition comprising:
at least 50 wt. % of a C 1-4 alcohol, based upon the total weight of the dispensable gel composition;
from 0.01 to 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
a diol plug-preventing additive, wherein said diol plug-preventing additive is present in an amount of 1 wt. % or less, based upon the total weight of the dispensable gel composition.
10. The dispensable gel composition of claim 9 , wherein the dispensable gel composition comprises from 0.1 to 1 wt. % of the diol plug-preventing additive, based upon the total weight of the dispensable gel composition.
11. The dispensable gel composition of claim 9 , wherein the dispensable gel composition comprises from 0.15 to 0.7 wt. % of the diol plug-preventing additive, based upon the total weight of the dispensable gel composition.
12. The dispensable gel composition of claim 9 , wherein the dispensable gel composition comprises from 0.25 to 0.5 wt. % of the diol plug-preventing additive, based upon the total weight of the dispensable gel composition.
13. The dispensable gel composition 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 thereof.
14. The dispensable gel composition 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 thereof.
15. The dispensable gel composition of claim 10 , wherein the dispensable gel composition comprises at least 60 wt. % of said C 1-4 alcohol.
