Claims14
A process for the production of hydrophilicized triglycerides, which comprises:
- a) reacting at least one unsaturated triglyceride having an iodine value of from 80 to 180, of the formula:
- ##STR2## wherein R.sup.1 CO, R.sub.2 CO and R.sub.3 CO independently of one another represent optionally hydroxy-substituted acyl radicals having 6 to 24 carbon atoms and up to 5 double bonds, with ethylene oxide in the presence of glycerol and an alkaline catalyst to form an ethoxylated triglyceride mixture;
- b) sulfonating the ethoxylated triglyceride mixture with gaseous sulfur trioxide to form a sulfonated mixture;
- and
- c) neutralizing the sulfonated mixture with an aqueous base.
