Leverkusen, Germany - New face powders and make-up are on offer using what seems at first glance to be an unlikely option: polyurethane powder and dispersions developed specifically for the cosmetics industry by Bayer MaterialScience.
According to BMS, the products give, "an extremely pleasant, silky skin feel," in powders, while liquid make up can be "particularly easy to apply and not sticky." In hairsprays, Baycusan C 1001 gives products where, "the hair looks natural, not stiff or stuck together," while tests confirm "outstanding curl-holding ability," said a BMS press release.
BMS' new business innovation manager Dr Sophie Viala introduced the new polymers - called Baycusan R - in a technical presentation at the In-Cosmetics trade show in Amsterdam, 15 - 17 April. Viala illustrated how face- and skin-care products, as well as cosmetics and hair sprays, benefit from the polyurethane material.
PU dispersions Baycusan C 1000 and Baycusan C 1004 have film-forming properties and impart decorative cosmetics "with extraordinary water resistance:" mascara containing Baycusan C 1000 is clearly more waterproof than standard types, for example, the polymer group said.
BMS also said that these two materials allow the formulating of long-lasting flexible films for make-up, eyeliner and eye shadow that do not feel greasy on the skin.
A speciality grade, Baycusan C 1003, is for masks which pull off the skin in one piece, with a light peeling effect, leading to "excellent cleansing," BMS said.
"Waterborne PU dispersions are not only solvent-free, they are also free of preservatives," said Viala, so that Baycusan C is both environmentally friendly and gentle on the skin.
