ABSTRACT:
Provided is a pigment dispersant having excellent pigment dispersibility thus allowing a larger amount of pigments to be blended in various cosmetics, and capability of imparting good sense of use, make-up lasting, odor, and stability over time to the cosmetic. A trehalose fatty acid ester composition prepared by esterifying trehalose with a fatty acid having 8 to 22 carbon atoms, which has a hydroxyl value of 20 to 500, and the total amount of a diester, a triester, a tetraester and a pentaester in the trehalose fatty acid esters of 10 to 100% by area; and a cosmetic including the trehalose fatty acid ester composition.
