Description

Peg-25 Paba is a water-soluble, polymeric derivative of para-aminobenzoic acid (PABA) where the molecule is ethoxylated with an average of 25 moles of ethylene oxide. This chemical modification enhances its solubility and stability, making it a valuable functional ingredient for advanced formulations. It is primarily utilized as a light-absorbing agent and UV filter in industries where product protection and performance are critical. Key sectors that rely on this compound include personal care, cosmetics, and specialty chemical manufacturing.

Application

• Sunscreen and Sun Care Products: Acts as a water-soluble UV filter, providing broad-spectrum protection in lotions, creams, and sprays.
• Anti-Aging and Protective Cosmetics: Incorporated into serums and day creams to shield the skin from photoaging caused by UVA/UVB radiation.
• Hair Care Formulations: Used in shampoos, conditioners, and styling products to protect hair color and integrity from sun damage.
• Functional Coatings: Serves as a light stabilizer in coatings and films where UV degradation is a concern.
• Pharmaceutical Topicals: Employed in certain dermatological preparations requiring photoprotective properties.
• Industrial Stabilizers: Applied in polymer and material science to enhance the light stability of sensitive compounds.
