Description

Octyl 4-Aminobenzoate is an organic ester derivative of para-aminobenzoic acid (PABA), widely recognized for its UV-absorbing properties. This compound is valued for its ability to provide effective and stable protection against ultraviolet radiation in various formulations. It serves as a critical functional ingredient for manufacturers in the personal care, pharmaceutical, and specialty chemical industries seeking reliable broad-spectrum UV filters.

Application

• Sunscreen & Personal Care Products: A primary active ingredient in sunscreens, lotions, and after-sun products, offering UV-B filtering properties.
• Cosmetic Formulations: Used in makeup, lip balms, and daily moisturizers to provide sun protection factor (SPF) enhancement.
• Pharmaceutical Topicals: Incorporated into medicated creams and ointments where UV protection is required for light-sensitive active ingredients or skin.
• Polymer & Coating Stabilizer: Acts as a light stabilizer in plastics, paints, and coatings to prevent UV-induced degradation and yellowing.
• Hair Care Products: Used in shampoos, conditioners, and styling products designed to protect hair from sun damage.
• Industrial UV Protection: Employed in formulations for textiles, automotive products, and other materials requiring UV resistance.
