Peregal O-80 (Fatty alcohol polyoxyethylene (80) ether) is a white to slightly yellow flake or waxy solid at room temperature, with a melting point of 45~55°C. Due to its solid form, it is recommended to slice or crush it before use, then slowly add it to 70~80°C hot water while stirring to dissolve, preparing a 10%~20% stock solution or working solution, which is then added to the final formula as needed. Avoid direct low-temperature feeding, as the dissolution rate will be extremely slow.
This product has an HLB value as high as 18.5, belonging to the typical O/W type emulsifier, with a cloud point >100°C. It exhibits excellent acid, alkali, and hard water resistance, and is designed with low foam characteristics, making it particularly suitable for processes requiring foam control. Since its active content is ≥99%, the optimal dosage should be determined through small-scale trials first to avoid cost waste or formula stability issues due to excessive use.
