Abstract
The invention relates to a series of novel silicone alkoxylated ester salts which contain terminal carboxyl groups which have been neutralized with various fatty amine compounds. This class of compounds provides a high dense foam and unique solubility in many organic solvents as well as very substantive salts of the carboxylic acid when neutralized with base. The compounds of the present invention are prepared by reacting a the hydroxyl group in a silicone polymer with an anhydride, followed by neutralization with an amine.
