The alkyl esters, when added to cosmetic compositions containing a sun filter, increase their SPF value by 50% or higher. As a result, the amount of sun filter in the cosmetics can be significantly reduced while maintaining a high SPF. The SPF booster effect was observed in different types of cosmetic compositions and with different sun filters. The alkyl esters have a strong natural connotation and can be obtained by eco-friendly synthesis methods. Photoprotective cosmetic compositions are thereby obtained which are safe to use and have better acceptance by the consumer.
