Hyperbranched Functional Polyolefins for Use as Pigment Grinding Aids

New Phase Technologies discloses hyperbranched polyolefins with acetate ester functionality for use as pigment grinding aids.  Pigment grinding aids are liquids used to predisperse pigments before adding to color cosmetics products such as lipsticks, foundation, mascara, etc.

The functional hyperbranched polyolefin and the corresponding pigment grinds are compatible with ingredients commonly found in color cosmetics including, but not limited to, castor oil, emollient esters, natural waxes such as beeswax and candelilla, microcrystalline wax, and synthetic waxes such as polyethylene.

In addition to providing a vehicle to predisperse pigments, the functional hyperbranched polyolefins also exhibit film forming properties on the skin.  Typical levels of the functional hyperbranched polyolefin in pigment grinds range between 35 to 70 percent.  Useful products are liquids and possess saponification values ranging from about 60 to about 100.
