Sorbitan tristearate, often referred to as Span 65, is a versatile lipophilic surfactant recognized for its significant emulsifying abilities in water-based systems, making it ideal for creating water-in-oil emulsions. As a nonionic ester surfactant, it offers superior emulsification, emollient, and lubricant properties, which enable its broad applicability across various industries, including food, personal care, pharmaceuticals, agrochemicals, cleaning, textiles, paints and coatings, lubricants, and chemical processing. It is also valued in deodorants and hair grooming products for its role as an effective coupling agent and co-emulsifier, particularly with mineral oils. Notably, sorbitan tristearate is derived from renewable vegetable sources and is biodegradable, aligning with sustainability goals. It is safely used in personal care products due to its low irritancy and non-hazardous classification for both users and the environment. Furthermore, it complies with global chemical inventories, such as EINECS, TSCA, AICS, ENCS, ECL, and PICCS, and adheres to European Pharmacopoeia specifications for pharmaceutical use, making it suitable for food contact applications as well.
