Description

Hexadecyl 2-Hydroxybenzoate is a high-purity organic ester compound, also known as Cetyl Salicylate. This versatile chemical intermediate is valued for its lipophilic character and functional properties, making it a key ingredient in advanced formulations. It is primarily sought after by manufacturers in the personal care, cosmetic, and specialty chemical industries for its role as an emollient, UV absorber, and solubilizer.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient and skin-conditioning agent in sunscreens, moisturizers, and anti-aging creams.
• UV Protection & Stabilization: Serves as a liquid UV-B filter and stabilizer in sunscreen products and polymer systems to prevent degradation.
• Pharmaceutical Topicals: Used as an excipient in ointments, creams, and topical drug delivery systems for its solubilizing and skin-penetration enhancing properties.
• Fragrance & Perfumery: Employed as a fixative and solvent for fragrance oils due to its low volatility and excellent solvating power.
• Specialty Lubricants & Additives: Functions as a synthetic base oil or additive in high-performance lubricants and release agents.
• Plastic & Polymer Additive: Utilized as a light stabilizer and internal lubricant in PVC and other polymer processing.
