Description

Octyl 4-Methoxycinnamate is a synthetic organic ester widely recognized for its ability to absorb ultraviolet light. This compound is a critical ingredient for formulators seeking to provide effective UV-B protection in a variety of consumer and industrial products. It is primarily utilized by manufacturers in the personal care, cosmetics, and specialty chemical industries to enhance the sun protection factor (SPF) and photostability of their formulations.

Application

• Primary UV-B Filter in sunscreens, sun care lotions, and daily moisturizers with SPF.
• Photostabilizing Agent in cosmetic formulations to protect other active ingredients from UV degradation.
• Key Ingredient in after-sun products, lip balms, and makeup foundations with sun protection claims.
• Industrial UV Absorber in coatings, plastics, and packaging materials to prevent yellowing and polymer degradation.
• Additive in hair care products designed to protect color-treated hair from sun damage.
