  • Patent number: 8496918
    Abstract: The present invention is directed to a series of polymeric glyceryl esters that have two different molecular weight ester chains, one solid and one liquid, which when combined into a single molecule make a polymer that is solid, but has very unique flow properties. These materials find applications as additives to formulations in personal care products where there is a desire to have a structured film (provided by the solid fatty group) and flow properties, (provided by the liquid fatty group). These compounds by virtue of their unique structure provide outstanding skin feel.
