  • Patent number: 5478490
    Abstract: A shampoo formulation containing a polyglyceryl ester as the viscosity builder is disclosed. These polyglyceryl esters have the formula:R.sup.5 OCH.sub.2 --CH(OR.sup.4)--CH.sub.2 --(O--CH.sub.2 CH(OR.sup.3)--CH.sub.2).sub.n --O--CH.sub.2 --CH(OR .sup.2)--CH.sub.2 OR.sup.1wherein n is from 4 to 14 and one or more R groups is an acyl group containing from 8 to 22 carbon atoms and the remaining R groups are hydrogen. Such shampoos may be formulated to meet the criteria for both baby and adult shampoos without the need of using ethylene oxide derivatives. By tailoring the polyglyceryl ester employed, a pearlescent appearance can be created and characteristics such as viscosity and clarity may be affected.

  • Patent number: 5077331
    Abstract: Propylene glycol esters of unsaturated fatty acids having from 8 to 20 carbon atoms are found useful as internal lubricants for polyvinyl chloride. As compared to commonly used materials, the use of propylene glycol ester results in improved optical properties, as for example low yellowing after processing and resistance to hazing upon immersion in liquids. The lubricants are used in the manufacture of PVC by bulk or suspension polymerization. Broadly from 0.1 to 5 wt. % of the ester is incorporated into the resin.

  • Patent number: 4481324
    Abstract: Enhanced lubricating properties and good heat stability upon processing are imparted to thermoplastic materials such as polyvinyl chloride, polypropylene and acrylonitrile-butadiene-styrene resins by the incorporation therein of a polyglycerol ester of a C.sub.8 to C.sub.22 fatty acid. The ester is characterized by a degree of polymerization ranging from 2 to 8 and a degree of acid substitution ranging from 1 to 10.
