Sunlight puts us in a good mood and is important
for our health. Like so many other things, however, dosage is critical. If you spend too much time in the sun too often, high-energy UV rays can cause major damage to your skin over the long term. Longwave UVA radiation causes the skin to tan quickly for short periods, and long-term exposure ages the skin prematurely. Shortwave UVB radiation, on the other hand, is responsible for sunburns that, in the worst-case scenario, can produce skin cancer. For these reasons, dermatologists advise all sun worshipers to protect their skin with sunscreen—and to err on the side of applying it too thickly rather than too thinly. Over 40 million packages are sold in German groceries and pharmacies each year as a result. Sales in this segment are currently estimated at roughly €213.9 million—and that trend is rising.
The factor by which a sunscreen increases protection from dangerous UVB rays relative to unprotected skin is indicated on the package as the sun
protection factor, or SPF. In these products, various chemical substances filter the radiation.
VESTASOL®, which is to a large part made from isophorone, Evonik’s Crosslinkers business line offers
cosmetic actives manufacturers a basic material for producing highly active UVB filters. Put simply, VESTASOL® provides the critical foundation for all of the subsequent synthesis steps needed to generate UVB protection in sunscreens. The UV filters approved for use in Europe are listed in Germany’s Cosmetics Ordinance. In addition, processing the
isophorone further removes this chemical building
block from the final product.
