ABSTRACT:
A new method for the preparation of acetals of long chain fatty aliphatic aldehydes and polyols containing four or more hydroxyl groups which produces the acetals in a relatively pure form by reaction in a mutual solvent, preferably a C.sub.1 to C.sub.4 fatty carboxylic acid. The `clean` acetals are useful emulsifying agents and their esters and polyalkoxy substituents are useful dispersants and surfactants for aqueous compositions.
