Polysorbate 60 O/W Emulsifier Liquid

Polysorbate 60 O/W Emulsifier Liquid CAS NO 9005-67-8 Polysorbate-60 (commonly known as Tween-60) is a non-ionic surfactant prepared by partial esterification of sorbitol and stearic acid, followed by ethoxylation with 20 moles of ethylene oxide. At room temperature, it appears as a yellow viscous liquid with a relative density in the range of 1.06-1.09. The HLB value reaches 14.5, making it a typical oil in water (O/W) emulsifier. It is soluble in warm water, ethanol, and ethyl acetate, but not miscible with mineral oil and vegetable oil. It is widely used in emulsion systems that require long-term stability under different ionic strengths and pH environments.   How It Works As an oil in water emulsifier, polysorbate -60 helps stabilize the formation of lotion by reducing the interfacial tension between oil and water. The hydrophilic ethoxy chain interacts with water, and the lipophilic stearate is embedded in the oil phase to build a tight interface structure, prevent oil droplets fr…
