1. A polyol fatty ester, comprising:
(i) a fatty moiety selected from:
a branched fatty moiety, which is a straight C14, C16, C18 or C20 lipid carboxyl group carrying a 10-methyl or 10-methylene branched substituent, or
a straight fatty moiety, which is a straight C14, C16, C18 or C20 lipid carboxyl group carrying a unique unsaturation in a position ranging from 7 to 10,
(ii) a polyol moiety having at least one hydroxyl group, which is a polymer composition of a C6 carbohydrate in the form of a dextrin having optionally branched polymer chain comprising more than 50 wt % of from 12 to 35 C6 carbohydrate monomers, wherein each polyol moiety in the said polymer is identical or different,
wherein the polyol fatty ester contains at least one fatty moiety according to (i), which is linked by ester bonding to the at least one hydroxyl group of the polyol moiety according to (ii),
wherein all the hydroxyl groups present on the polyol moiety are esterified.
