Polysorbate 40 is a non-ionic, hydrophilic surfactant produced by reacting the ethylene oxide with polyol and sorbitol. Then the polyoxyethylene sorbitan is reacted with fatty acids, resulting in the formation of polyoxyethylene sorbitan mono-oleate. Fatty acids are derived from vegetable fats and oils such as oleic acid, stearic acid, palmitic acid, and lauric acid. It is also known as polyoxyethylene sorbitan mono-oleate or polyoxyethylene (20) sorbitan monopalmitat. Polysorbate 40 has a wide range of applications such as surface coating type antistatic agents, emulsifier for water based metal process cutting oils, emulsifier for adjuvant of agrochemicals, stabilizer for emulsion polymerizations, stabilizer for color materials, emulsifier for pharmaceuticals, fragrances solubilizer, detoxifying agent in shampoos, emulsifier and conditioning agent in cosmetics. Global polysorbate 40 market is expected to expand at substantial growth rate over the forecast period. Asia-Pacific is projected to dominate the global polysorbate 40 market over the forecast period, owing to the increasing consumption of colorants in food and cosmetics products in the region.
