A new line of polyurethanes- Baycusan®, has been specifically designed for the cosmetics industry, offering a number of advantages over conventional polymers, by Bayer MaterialScience. Baycusan® contain no solvents, making them environmental friendly. They can be used to formulate skin and hair care products that emit little or no volatile organic compounds (VOCs). Baycusan® thus gives cosmetics producers great latitude in the formulation of their products. Film properties can be adjusted: from flexible to hard; from waterproof to water vapor permeable. Baycusan® also contains no preservatives.
As a film former in hair styling products, Baycusan® PU dispersions offer significantly greater hold at high humidity than the polymers used previously. Another plus: The hair is very easy to comb. The new dispersions can also be used to advantage in peel-off masks that can be peeled off the skin as a single piece. Used in decorative cosmetics, the new polyurethanes improve the water resistance of mascara, lipsticks and eyeliner. As high-grade fillers in face and body care products, Baycusan® PU powders impart creams and lotions with a silky skin feel both during and after application.
