Peregal O-80 (Chemical name: C16-18 alcohol polyoxyethylene (80) ether, CAS No.: 68439-49-6) is a high-degree polymerized fatty alcohol polyoxyethylene ether nonionic surfactant. With its excellent core properties of emulsification, wetting, dispersion, and solubilization, as well as strong tolerance to acid, alkali, and high-hardness water environments, Peregal O-80 has become an irreplaceable formulation component in many industrial fields.
In emulsification applications, Peregal O-80 is specifically used to construct long-term stable oil-in-water (O/W) emulsion systems. Its high HLB value enables uniform dispersion of hydrophobic substances in the aqueous phase. In terms of dispersion and wetting, it effectively inhibits re-agglomeration and sedimentation of solid particles, significantly improving the uniformity and stability of the formulation. Additionally, its notable solubilization effect greatly enhances the compatibility and transparency of hydrophobic substances in water-based formulations, providing strong support for the performance of end products.
From a safety and environmental perspective, Peregal O-80 is a non-hazardous substance with an acute oral LD50 greater than 5000 mg/kg (practically non-toxic), non-irritating to skin and eyes, and a 28-day rapid biodegradation rate of over 60%, making it readily biodegradable. It meets current environmental sustainability requirements and offers a broad safety margin for industrial applications.
