OP-10 (octylphenol polyoxyethylene ether, CAS: 9036-19-5) is a non-ionic surfactant. With its excellent emulsifying, wetting, penetrating, dispersing and cleaning properties, it serves as a key functional auxiliary in multiple industries. The following application data comes from the product technical data of Haian Guoli Chemical Co., Ltd. and industry application practices.
| Industry | Specific Process/Use | Functional Role |
|---|---|---|
| Industrial and Household Cleaning | Metal degreaser, hard surface cleaner | Emulsify oil and dirt, enhance detergency |
| Textile Printing and Dyeing | Penetrant, leveling agent, wetting agent | Promote uniform penetration of dye solution into fibers |
| Pesticide Formulations | Emulsifiable concentrate, aqueous emulsion processing | Emulsify and disperse active ingredients |
| Water-Based Coatings and Inks | Wetting dispersant, emulsion polymerization emulsifier | Improve pigment dispersion, prevent sedimentation |
| Leather Processing | Degreasing process | Remove natural and process fats and oils |
| Papermaking Industry | Felt cleaning, deinking of waste paper | Promote ink separation and removal |
| Oilfield Exploitation | Crude oil demulsification and dehydration, acidizing additive | Improve oil-water separation efficiency |
| Metalworking | Cutting fluid, grinding fluid component | Lubrication, cooling, cleaning |
OP-10 remains stable under a wide range of acid-base conditions and in hard water, and has good compatibility with anionic, cationic and other non-ionic surfactants. The recommended dosage varies with the process, typically 1% to 10% of the total formulation. When used in emulsifying systems, the HLB value is about 13.5, suitable for preparing O/W type emulsions.
