Abstract
Various triglycerides (coconut oil, palm kernel oil, tallow) were ethoxylated with a proprietary catalyst (calcium/aluminum alkoxide complex partially neutralized in an alcohol ethoxylate base) to obtain triglyceride ethoxylates. Triglyceride ethoxylates were then partially saponified with sodium hydroxide to form mixtures of mono-, di-, and triglyceride ethoxylates, fatty acid soap, and glycerol ethoxylate. These mixtures were characterized in terms of physical properties, surface activity, and mildness. Partially saponified triglyceride ethoxylates were found to be unexpectedly mild and capable of imparting mildness to other surfactants.
