Sucrose stearate is a natural emulsifier, also known as a sugar ester, formed by combining sucrose (table sugar) with stearic acid. It is commonly used in cosmetics and personal care products as a skin-friendly ingredient. Sucrose stearate helps to blend oil and water-based ingredients, improving the texture and stability of products like creams and lotions. It also acts as a mild detergent and emollient, leaving the skin feeling soft and moisturized.
