Peregal O-15 (fatty alcohol polyoxyethylene (15) ether), as a mature nonionic surfactant, is typically stable in practical applications. However, due to various factors such as formulation systems, process conditions, and storage environments, occasional issues such as poor emulsification, incomplete dissolution, abnormal foam, or compounding turbidity may arise. In such cases, it is recommended to first conduct a systematic investigation from the following aspects to quickly identify the root cause of the problem.
If the problem still cannot be resolved after self-investigation, Haian Guoli Chemical Co., Ltd., as the manufacturer, has a complete technical service system that can provide you with professional application guidance and solutions. You can directly contact the technical department of Guoli Chemical for customized technical support tailored to your specific process and formulation.
| Problem Phenomenon | Possible Causes | Recommended Measures |
|---|---|---|
| Poor emulsification, emulsion separation | HLB value mismatch; insufficient dosage; improper oil-to-water phase ratio; inappropriate temperature | Confirm the required HLB value of the oil to be emulsified, adjust the dosage of Peregal O-15 (recommended starting from 3% to 8%); optimize emulsification temperature (generally 50~70°C) and homogenization speed |
| Dissolution precipitation or turbidity | Water temperature too low; interference from calcium and magnesium ions in hard water; extreme pH | Pre-dissolve in warm water at 40~50°C before adding to the system; pretreat water with chelating agents; adjust pH to neutral or weak acid/alkali range |
| Compounding failure with anionic/cationic auxiliaries | Improper ratio; incorrect addition sequence | Peregal O-15 is nonionic with good compatibility, but it is recommended to avoid direct mixing with high concentrations of strong anions simultaneously; use a stepwise addition method |
| Abnormal product color or form | Excessive storage temperature causing melting and caking; moisture absorption | Check storage environment to ensure it does not exceed recommended temperature; slight caking does not affect performance; use as soon as possible |
| Decreased cleaning or wetting power | Incompatible use temperature; insufficient concentration | Peregal O-15 is suitable for medium to high temperature cleaning (recommended 50~80°C); check if the working solution concentration meets formulation requirements |
| Foaming issues | Air entrainment in the system; water quality changes | This product is low-foaming; abnormal foam usually originates from other components in the system or mechanical air entrainment; adding a trace amount of defoamer can improve the situation |
To minimize problems during use, it is recommended to follow these best practices:
When handling Peregal O-15, always wear protective gloves and goggles to avoid direct contact with skin and eyes. In case of accidental eye contact, rinse immediately with plenty of clean water for at least 15 minutes and seek medical attention. This product has long-term persistent effects on aquatic organisms; strictly prevent it from entering water environments. For detailed safety information, refer to the Safety Data Sheet (SDS).
