1.Product Property
OP-10P is a colorless to pale-yellow transparent liquid at 25 °C, readily soluble in water and most organic solvents. It exhibits outstanding alkaline stability, retaining strong detergency even under concentrated caustic conditions. The product provides excellent antistatic, emulsifying, smoothing and softening effects, and has a solid content ≥95 % with a pH (2 % aqueous solution) ≤3.0.

3.Application Scope and Usage
OP-10P is widely used as a high-performance emulsifier for acrylic, styrene-acrylic and vinyl acetate polymerization, as a wetting agent in water-borne paints, inks and coatings, and as a detergent in household and industrial cleaners. In textiles it serves as a leveling and scouring agent; in agrochemicals it stabilizes emulsifiable concentrates and suspension concentrates. Typical dosage is 0.1–3 % by weight of the formulation, added during the emulsification or compounding stage under moderate agitation at 30–60 °C.
4.Package and Storage
OP-10P is supplied in 200 kg net nitrogen-blanketed HDPE drums or 1000 kg IBC totes; small lots are available in 25 kg HDPE pails. Store in a cool, dry, well-ventilated warehouse away from direct sunlight, moisture, strong oxidizers and acids. Recommended storage temperature is 5–35 °C; at lower temperatures partial crystallization may occur—re-homogenize by gentle warming below 50 °C. Drums should be tightly resealed after use; shelf life is 24 months from production date when stored under stated conditions.
