Tristyrylphenol ethoxylates

Tristyrylphenol ethoxylates (CAS 99734-09-5), also known as ethoxylated polyarylphenol or polyethylene glycol mono(tristyrylphenyl)ether, are nonionic surfactants built around a bulky tristyrylphenol hydrophobe. This unique chemical structure delivers strong emulsification, wetting, and dispersing performance across a range of industrial formulations. In agrochemical formulations, they function as emulsifiers and dispersants.

They are used in emulsifiable concentrates, suspension concentrates, and wettable powders to improve active ingredient stability and field performance. Textile processing operations use them as wetting and scouring agents. These surfactants are also utilized during fiber preparation, dyeing auxiliaries, and finishing baths. Industrial and institutional cleaning formulators incorporate them into hard surface cleaners and degreasers.

They provide robust soil emulsification under varied water conditions. In leather processing, they support fat liquoring and degreasing steps where consistent emulsification of hydrophobic materials is critical. Tristyrylphenol ethoxylates are supplied as liquid or viscous paste, with HLB and ethoxylation degree determining grade selection. Technical-grade material is the standard commercial offering for industrial use.

EO chain length variants are available to tune hydrophilicity for different formulation requirements. Bulk supply in drums and IBC containers is typical for industrial buyers seeking high-performance surfactants.
