An oil or fat composition containing 15 wt % or more of diglyceride (component (A)) and 70 ppm or more, on the basis of the diglyceride, of an organic carboxylic acid (Component (B)).

Oil or fat composition

A polyol fatty acid ester having mixed acid groups is produced by reacting a partial ester of a polyol and a branched fatty acid with a a straight chain fatty acid or a lower alcohol ester thereof in the presence of a lipase. The obtained glyceride mixture contains a large amount of diglyceride having a branched, saturated fatty acid group and a straight chain, saturated fatty acid group.

Process for preparation of polyol fatty acid ester and glyceride mixture

The following diacylglycerin is useful for a cosmetic oil and a cosmetic composition such as pack, cream and emulsion. ##STR1## (where one each of R.sub.1, R.sub.2, and R.sub.3 denotes a residue of a straight-chain saturated fatty acid having 11-17 carbon atoms, a residue of a branched-chain saturated fatty acid having 10-18 carbon atoms, and a hydrogen atom).
