    摘要: Processes for preparing random polytrimethylene ether ester are provided. The processes include contacting 1,3-propanediol with a suitable polymerization catalyst, wherein the 1,3-propanediol comprises about 10 microg/g or less peroxide compounds, based on the weight of 1,3-propanediol, and about 100 microg/g or less carbonyl compounds based on the weight of the 1,3-propanediol.

    摘要: This invention relates to cosmetic compositions containing aqueous nanodispersions of polyurethane ionomers based on polytrimethylene ether glycol (“PO3G”), and an active cosmetic ingredient. In a particularly preferred embodiment, the PO3G is derived predominantly from monomers obtained from renewable resources, making the personal care products of this embodiment of the present invention more environmentally friendly in terms of their manufacture, use and disposal.
