  • Patent number: 8471047
    Abstract: The present invention relates to a series of mixed esters of glycerin esters having two distinct alkyl groups present thereon. One is a low melting product, having a melting point of below 70° C. and the other having a melting point of above 90° C. The presence of the two different melting point groups on the glycerin results in a modification of the hardness, spredability and aesthetics of the resulting mixed ester. This ability to alter hardness and skin aesthetics makes the products of the present invention useful in personal care products ranging as additives to pigmented products to minimize syneresis, to stick products alter the hardness, shrinkability and aesthetics of the stick, to pressed powders where they act to modify the compressability of the powders to which they are added as well as the feel achieved when they are applied to the skin.
