Peregal O-10 (chemical name: fatty alcohol polyoxyethylene (10) ether, CAS number: 68439-49-6) is a flagship nonionic surfactant product of Guoli Chemical, with a molecular formula of R(OCH₂CH₂)₁₀OH (R is C12-14 alkyl) and an average molecular weight of about 640. The product appears as a white to light yellow paste, with a melting point of approximately 25°C. It remains paste-like at lower room temperatures and becomes more fluid when heated.
The core performance parameters of this product include: HLB value of 12.5, making it a hydrophilic emulsifier suitable for preparing oil-in-water (O/W) emulsions; cloud point of 60-70°C, at which it precipitates from water at high temperatures; active matter content ≥99%, free alcohol ≤1%, ensuring high efficiency and stability. The aqueous solution is slightly acidic to neutral, with pH values of 5.0-7.0 for both 1% and 5% aqueous solutions, close to the pH of human skin, making it suitable for personal care formulations.
As a typical nonionic surfactant, Peregal O-10 is chemically stable, resistant to acids, bases, and hard water, with broad compatibility. It can be compounded with nonionic, anionic, cationic, and amphoteric surfactants in any ratio, offering high flexibility in formulation design.

Based on the HLB value of 12.5 and cloud point of 60-70°C, Peregal O-10 is recommended for the following scenarios:
According to Guoli Chemical database safety information, this product is GHS classified as Skin Irritation Category 2 (H315) and Eye Irritation Category 2 (H319). Protective gloves and goggles should be worn during operation. Storage temperature is recommended to be controlled between 10°C and 35°C, avoiding prolonged high temperature (>40°C) or freezing (<0°C) to prevent product stratification or performance degradation. The product itself is non-flammable with a flash point >180°C, but dust or aerosol may pose a combustion risk under specific conditions.
