Peregal O-15 (CAS number: 68439-49-6), also known as AEO-15, Emulsifier O-15, Leveling Agent O-15, belongs to the fatty alcohol polyoxyethylene ether (AEO) series, produced by the addition polymerization of natural fatty alcohols with 15 ethylene oxide (EO) molecules. The hydrophobic fatty alcohol carbon chain and the hydrophilic polyoxyethylene chain in its molecular structure endow the product with excellent amphiphilic properties, making it an indispensable core component in formulation systems.>
The product appears as a white to slightly yellow flake or paste solid, easy to store, transport, and accurately dose. As a nonionic surfactant, Peregal O-15 exhibits excellent resistance to acids, alkalis, and hard water stability, and can be well compounded with nonionic, anionic, cationic, and amphoteric auxiliaries, demonstrating broad formulation compatibility. Its high solid content and high active matter purity ensure cost-effectiveness and formulation reliability in use.
Peregal O-15 is a low-toxicity chemical (rat oral LD50 > 2000 mg/kg), but attention should still be paid to its potential for skin irritation (Category 2) and serious eye irritation (Category 2A), and it has long-lasting effects on aquatic organisms (Category 3). It is recommended to wear protective gloves, goggles, and protective clothing during operation, avoid direct contact, and prevent the product from entering water bodies.

Due to its long EO chain and prominent hydrophilicity, Peregal O-15 is particularly suitable for scenarios requiring good water solubility and emulsion stability:
1. Textile Dyeing and Printing: Used as a high-efficiency leveling agent and retarding agent to promote uniform dye penetration during the dyeing process of various fibers, effectively preventing dyeing defects such as color spots and streaks; also used for emulsification and dispersion in pretreatment scouring and finishing processes.
2. Industrial Hard Surface Cleaning: As a core raw material for powerful degreasers, it has excellent emulsifying, dispersing, and removing ability for mineral oils and animal and vegetable fats, especially suitable for cleaning formulations of metal workpieces and mechanical equipment in medium to high temperature cleaning environments.
3. Daily Chemicals and Cosmetics: As an O/W emulsifier, suitable for formulating creams, lotions, sunscreens, and skincare products; also used for efficient solubilization of fragrances and essential oils in water-based formulations, improving product transparency and stability.
4. Pesticide Formulations: Used as an emulsifier in emulsifiable concentrates (EC) and emulsion in water (EW) systems, significantly improving the spontaneous emulsification and dispersibility of the pesticide solution in water, enhancing the effective utilization of pesticides.
5. Other Industrial Fields: Used as a degreasing agent and wetting agent in leather processing; as a rewetting agent in the paper industry to improve liquid absorption of tissues; as a wetting and dispersing agent for pigments and fillers in paints and inks to prevent floating, flooding, and sedimentation.
