Description

Homosalate is an organic ester widely recognized as a highly effective oil-soluble UV-B filter. This compound matters for its ability to absorb ultraviolet radiation, providing critical protection against sun damage in a variety of formulations. It is a key ingredient sought by manufacturers in the personal care and cosmetics industries for sunscreens, after-sun products, and daily moisturizers with SPF protection.

Application

• Broad-Spectrum Sunscreen Formulations: Primarily used as a UV-B filter in sun care products (SPF 15-50+) to protect skin from sunburn.
• Daily Wear & Cosmetic Products: Incorporated into facial moisturizers, foundations, BB/CC creams, and lip balms to provide everyday sun protection.
• After-Sun & Skincare Lotions: Used in products designed to soothe and moisturize skin after sun exposure.
• Hair Care Products: Added to hair sprays, styling gels, and leave-in conditioners to protect hair color and integrity from UV degradation.
• Water-Resistant Formulations: Valued for its lipophilic nature, enhancing the water resistance of sunscreen products.
• Industrial & Protective Coatings: Employed in some industrial applications, such as UV-protective coatings for plastics and textiles to prevent yellowing and brittleness.
