Polysorbate 40
Polysorbate 40, also known as Tween 40, is a non-ionic surfactant and emulsifier derived from sorbitol and palmitic acid. It is widely used in cosmetic, pharmaceutical, food, and personal care formulations for its ability to emulsify, solubilize, and stabilize oil-in-water blends. With a higher fatty acid chain compared to Polysorbate 20, Polysorbate 40 offers enhanced emulsification and conditioning properties, making it ideal for thicker creams and lotion-type products. It ensures product stability, improves texture, and is gentle enough for sensitive applications.
Polysorbate 40 Overview
Polysorbate 40 excels in stabilizing oil-in-water emulsions, making it a preferred choice for thicker formulations like lotions, creams, and ointments. Its mild and non-irritating nature suits sensitive skin and baby care products, while its compatibility with various surfactants and oils allows for versatile formulation options. It enhances product texture and shelf life by preventing separation.
