Chemical Name: EO-PO Block Copolymer
Block Copolymer Surfactant
I.C.C manufactures a wide range of low foaming surfactants designed to provide the appropriate functionality for all of our customers application needs. We help you to get your foam under control. Polyol 93 is a block copolymer surfactant terminating in primary hydroxyl groups. A nonionic surfactant that is 100% active and relatively nontoxic. Polyol 93 is an amphiphilic EO-PO Block Copolymer that can form spherical core-shell micelles in aqueoussolution. The micellar core consists of the hydrophobic blocks and the shell region consists of the hydrophilic blocks.

Appropriate literature has been assembled which provides information concerning the health and safety precautions that must be observed when handling PPG 500 polyol. Before working with these products, you must read and become familiar with the available information on their hazards, proper use, and handling
Block copolymers are used in numerous applications
such as cosmetics, detergency, textiles,
emulsification, polyurethane foams and drug adjuvant,
because of their ability to form various aggregates in
water and their low toxicity
