Abstract
The present invention relates to a series of esters that are water insoluble and hydrophobic. Surprisingly however we have found that by selecting the proper polyester having (a) a dipentaerythritol portion, in which several hydroxyl groups remain unreacted and consequently polar, (b) a polyhydroxystearic acid polyester portion and (c) a mono-fatty acid portion esters that will have an affinity for water are prepared. These esters allow for the incorporation of three times their weight in water into pigmented products, where they improve creaminess, emmoliency, skin feel, humectancy and long wear.
