Styrenated Phenol Ethoxylate 16 (SPE 16) is a nonionic surfactant that is derived from the ethoxylation of styrenated phenol. It is a clear to light yellow liquid that is soluble in water and polar organic solvents. SPE 16 contains 16 moles of ethylene oxide per mole of styrenated phenol and has a relatively low cloud point, which makes it a useful ingredient in low-temperature applications. Styrenated Phenol Ethoxylate 16 is commonly used as an emulsifier, wetting agent, and dispersant in a wide range of industrial applications, including coatings, agrochemicals, textiles, and personal care products.

Styrenated Phenol Ethoxylate 16 (SPE 16) commonly known as Emulsogen TS 160, AGNIQUE TSP-16, SPE-16.
