XPO-4 (Glycerol Polyoxyethylene Ether Oleate) is a nonionic surfactant produced by Hai'an Guoli Chemical Co., Ltd. Its aliases include Polyoxyethylene Glycerol Ether Oleate, Polyoxyethylene Glycerol Monooleate, Oleic Acid Polyoxyethylene Glycerol Ester, etc. At room temperature, the product is a light yellow to yellow transparent viscous liquid. It occupies an important position in the chemical fiber printing and dyeing industry due to its excellent leveling and retardation properties.
From a chemical structure perspective, XPO-4 is synthesized with glycerol as the backbone, which undergoes polyoxyethylenation with ethylene oxide and then esterification with oleic acid, giving it a unique hydrophilic-lipophilic balance. It has excellent resistance to acid, alkali, and hard water, maintaining high efficiency under different water qualities and process pH conditions. Under high-temperature and high-pressure conditions, the product does not demulsify or separate, demonstrating outstanding thermal stability.
In terms of environmental protection and safety, XPO-4 has an acute oral toxicity LD₅₀ greater than 5000 mg/kg (rat), classifying it as a substance with low acute toxicity; its biodegradation rate exceeds 70% (OECD 301B method), making it readily biodegradable. It is irritating to the eyes (GHS Category 2, H319), so protective measures should be taken during handling.
1. High-Temperature and High-Pressure Leveling Agent (Core Use)
As a special leveling agent for polyester (polyester fiber) and its blended fabrics in the high-temperature and high-pressure dyeing process with disperse dyes. This product has excellent migration ability, effectively reducing the dye uptake rate, ensuring uniform adsorption and diffusion of dyes on the fiber surface and inside, significantly preventing dyeing defects such as color spots, color differences, and color points, improving color reproducibility and one-time dyeing success rate. At the same time, it has strong emulsifying and dispersing power for disperse dyes, effectively preventing dye particles from agglomerating and precipitating in the dye bath.
2. Industrial Emulsifier and Dispersant
With excellent surface activity, it is suitable for formulation systems such as inks, coatings, pesticide emulsifiable concentrates, and used as a high-quality industrial emulsifier and dispersant.
3. Chemical Fiber Oil Component
Used in the compounding of chemical fiber spinning oils, it imparts good smoothness, cohesion, and antistatic properties to the fibers, improving their spinnability and post-processing performance.
