To achieve a sun-kissed and even tan throughout the year without exposure to harmful UV radiation, the use of self-tanningTo achieve a sun-kissed and even tan throughout the year without exposure to harmful UV radiation, the use of self-tanningproducts is very popular among many consumers. The product selection in this segment is diverse, but alternatives to usableactive ingredients are low. Most manufacturers typically use dihydroxyacetone (DHA), which causes a tanning reaction in theuppermost skin layer. As the degree of tanning of the skin decreases steadily over time, for longer-lasting effects the self-tanningproduct must be reapplied at intervals of 3-5 days. Industry is looking for solutions to prolong those intervals. One interestingoption is the use of vegan silk to extend the tanning effect. So far, the use of functional, vegan silk was proven to extend therelease of fragrances and other actives such as insect repellents. Therefore, the influence of vegan silk on a potential prolongingeffect on DHA has been investigated. In formulation, even at pre-set pH values between 4 and 5, for the combination of DHAand vegan silk an excellent stability was determined. Here, it has been proven that the formulation with functional vegan silkcan achieve a longer-lasting tan. With increasing silk concentrations tanning results were significantly improved compared tothe usage of a conventional formulation without silk.
