Abstract
Cleansing agents are provided which are highly effective for removing makeup with excellent lathering, while at the same time providing a refreshing after-shampoo feeling. These cleansing agents comprise surfactants and polyoxyalkylene carboxylic acid esters represented by the following formula (1): wherein R1 and R2 are hydrogen or straight or branched chain alkyl groups having 1 to 4 carbon atoms; m, n, X and Y are integers of from 0 to 5 but are not all concurrently 0; and R3 is a straight or branched chain alkylene group having from 0 to 10 carbon atoms.
Claims11
A cleansing agent comprising one or more surfactants and one or more polyoxyalkylene dicarboxylic acid esters represented by the following formula (1):
- wherein R1 and R2 are hydrogen, or straight or branched chain alkyl groups having from 1 to 4 carbon atoms;
- m, n, X and Y are integers of from 0 to 5 and are not all concurrently 0;
- and R3 is a straight or branched chain alkylene group having from 0 to 10 carbon atoms.
A cleansing agent comprising at least one surfactant and at least one polyoxyalkylene dicarboxylic acid ester represented by the following formula (1):
- wherein R1 and R2 are hydrogen, or straight or branched chain alkyl groups having from 1 to 4 carbon atoms;
- m, n, X and Y are integers of from 0 to 5 and are not all concurrently 0 and the sum of m, n, X and Y is 15 or less;
- and R3 is a straight or branched chain alkylene group having from 0 to 10 carbon atoms, and the polyoxyalkylene diacarboxylic acid ester constitutes from 0.1 to 10% by weight of the total weight of the cleansing agent.
