Dodecyl 2-hydroxybenzoate, also known as lauryl salicylate, is primarily used as a UV absorber in sunscreen and cosmetic formulations to protect skin from UVB radiation. It functions as an emollient and skin conditioner, providing moisturizing benefits and improving the texture of products like lotions and creams. Additionally, it serves as a penetration enhancer for active ingredients in topical skincare products and may exhibit mild anti-inflammatory properties suitable for sensitive skin applications.
