LONDON, UK: Covestro said that it will be showcasing its innovative beauty solutions based on Baycusan polyurethane raw materials. Children and surfers, in particular, can look forward to this year’s swim season, because formulations containing the film-former Baycusan C 1004 are extra water-resistant. They retain more than 50 percent of their initial sun protection factor for over an hour even after repeated exposure to water.
Long-lasting sun protection

Even those who sweat while exercising on the beach can rely on long-lasting protection. In sauna tests, Covestro proved that over 60 percent of the sun protection factor is maintained. With its outstanding breathability, Baycusan C 1004 is very well-suited to protecting people from the sun when exercising.
“In view of the good rub-off resistance, we expect the skin to be sufficiently protected from the sun’s radiation even after drying off with a towel. Corresponding studies currently are being conducted,” said Dr Sophie Viala from the cosmetics team at Covestro.

The sun protection products are easy to apply and absorb quickly. Because the skin is not sticky, sand does not adhere to it and children won’t complain about that unpleasant, scratchy feeling. Covestro demonstrated these results using a method developed in-house: Up to 25 percent less sand adhered to the substrate when treated with sun protection formulations containing Baycusan C 1004 than with samples without the film-former.

Consumers increasingly are in search of sun protection solutions for sensitive skin. Conventional formulations can irritate the eyes when the UV absorber responsible for sun protection migrates to the skin’s surface. Customers want products that offer comprehensive protection against harmful UV radiation but do not irritate the skin.
Sun protection products containing the film-former Baycusan C 1000 are highly suitable for use on sensitive skin. They reduce the migration of UV absorbers to the skin’s surface by up to 80 percent. Even when used daily, the occurrence of skin irritations is highly unlikely. Because the raw material can well stabilise the formulation, less emulsifier can be used to reduce the risk of skin allergies.

Consumers want highly effective sun protection products that display high fresh water and salt water resistance and form a transparent film even on wet skin. With the new, ethanol-based polyurethane film-former Baycusan C 2000, Covestro has developed precisely the right product to meet these requirements. Even without the further addition of ethanol, sun protection oils formulated with this product feel pleasantly dry on the skin.
