Tetradecyl lactate is widely used in the cosmetics and personal care industry as an emollient and skin-conditioning agent. It helps to soften and smooth the skin by forming a protective barrier that retains moisture, making it a common ingredient in lotions, creams, and moisturizers. Its non-greasy texture and ability to enhance the spreadability of products make it ideal for formulations requiring a lightweight feel. Additionally, it is used in hair care products to improve manageability and add shine. Its compatibility with various cosmetic ingredients and its mild nature make it suitable for sensitive skin applications.
