Abstract
The invention is a new family of non-ionic surfactants and a method of making same. The surfactants are made by (1) alkoxylating an alkylphenol with an alkylene oxide using a standard alkylene catalyst; (2) hydrogenating the alkoxylated alkylphenol until it is either fully or partially saturated using selective catalysts such that the aromaticity of the compound is eliminated; (3) if necessary, further alkoxylating the resulting non-aromatic molecule. The resulting compound is an alkylcyclohexanol alkoxylate possessing excellent surfactant properties for use as a emulsifiers, for wetting and penetration, for scouring, and general surface modification.
