Destructible surfactants and methods of using same are provided. The application includes anionic surfactants having a dioxolane or dioxane functional group as represented by the formula
in which
p is 0, 1 or 2;
R is alkyl;
R 1 and R 2 are each, independently, hydrogen or methyl;
R 3 is selected from -OSO 3 - , -R 4 OSO 3 - , -R 4 OR 5 SO 3 - , and -OR 5 SO 3 - ,
wherein R 4 and R 5 are each, independently, lower alkyl;
with the provisos that when p is 0 and R 1 is methyl, R 3 is not -CH 2 O(CH 2 ) 4 SO 3 or when p is 1 and R 1 is hydrogen and R 2 is methyl, R 3 is not -CH 2 OSO 3 .
This enables the surfactant to be broken down under acidic conditions. The application also includes methods of making anionic surfactants and methods of using anionic surfactants in a variety of applications. |
