Chemical Name: Block Copolymer EO-PO
Grade: Chemical
Low Foaming Surfactants
Block Copolymer EO-PO I.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. Alkyl based EO-PO block copolymers typically have lower surface tensions, CMC and greater dispersing power compared to the corresponding simple alkyl ethoxylates. The propylene oxide block acts as a branched residue within the copolymers leading to performance advantages like better solubilization and emulsification properties

Copolymer 20-101 is dispatched in polyethylene or corrugated steel, galvanized or carbon steel drums. Copolymer 20-101 is stable for 2 years when stored in the original sealed containers in a cool and dry place. Precautions for safe handling Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Provide appropriate exhaust ventilation at places where dust is formed. Normal measures for preventive fire protection. Conditions for safe storage Keep container tightly closed in a dry and well-ventilated place

May cause eye irritation. Ingestion May be harmful if swallowed
Low-foaming EO-PO copolymers can be used in various solvent or water based formulation types e.g. likeEmulsifiable concentrate (EC) Oil-in-water emulsion (EW) Suspo-emulsion (SE) Soluble concentrate (SL) Suspension concentrate (SC). EO-PO copolymers act as emulsion stabilizers, wetters, penetration enhancers or dispersing agents. Whenever the wetting properties of your formulations need to be improved without causing increased foam formation alkyl substituted EO-POderivatives could be the right choice. Due to their different molecular weights and structures these types of surfactants are not necessarily enhancing the penetration through the leaf surface, which makes them suitable e.g. for the use with contactpesticides. Alkyl alkoxylates and EO-PO copolymers like copolymer 20-101, 20-102 and 20-103, 40-101,… showing fast cold-water solubility provide advantages especially in water
based formulations (SL, SC, SE). More hydrophobic copolymers like copolymer 20-101, … are used as emulsifiers and wetters in solvent or oil based systems (EC, EW)
