OPE-108 (octylphenol polyoxyethylene ether) is a non-ionic surfactant with an HLB value of about 13.5. It is easily soluble in water and various organic solvents. Its molecular structure contains about 8-10 ethylene oxide (EO) segments, giving the product excellent emulsifying, wetting, and dispersing capabilities. In practical applications, OPE-108 can be directly added to the aqueous or oil phase with stirring, or gradually added during mixing to ensure full dispersion and optimal performance.
Since OPE-108 is a high-concentration liquid (active content ≥99%), it maintains good fluidity even at low temperatures (pour point < -5°C), making it easy to handle. It is recommended to conduct small-scale tests before addition, and gradually adjust the addition ratio based on the target system's emulsification stability, wetting effect, or dispersion requirements. For aqueous systems, it can be pre-diluted with water or solvent before adding to avoid gelation or precipitation caused by local high concentration.
Although this product is non-ionic and has good compatibility, it should be noted that it is classified as skin corrosion/irritation category 1B and serious eye damage category 1. Personal protective equipment must be strictly worn during operation to avoid direct contact.
