Peregal O-25, with the chemical name fatty alcohol polyoxyethylene (25) ether, is a nonionic surfactant with an HLB value of approximately 16.0–17.0, offering excellent water solubility and chemical stability. The long polyoxyethylene chain in its molecular structure gives it a cloud point above 100°C, allowing it to maintain good surface activity even at high temperatures. It is unaffected by acids, alkalis, and hard water and can be widely compounded with anionic, cationic, and amphoteric surfactants. These properties make it an indispensable functional auxiliary in multiple industries.
In the textile printing and dyeing field, Peregal O-25 plays multiple roles as a leveling agent, soaping agent, and anti-staining agent, effectively slowing down dye uptake and preventing color spots. In industrial cleaning, it can quickly emulsify mineral oils, paraffin wax, and mechanical greases, making it suitable for spray, ultrasonic, and high-pressure hot water cleaning processes. In the daily chemical and pesticide fields, it plays key roles in gentle emulsification and wetting penetration, making it a versatile and highly adaptable general-purpose surfactant.
| Application Industry | Core Process/Use | Product Function | Recommended Dosage |
|---|---|---|---|
| Textile Printing and Dyeing | Leveling for direct, vat, acid, and disperse dyes; soaping after reactive dye printing | Retarding and leveling, preventing color spots and shade differences; removing unfixed dye at high temperature and preventing re-staining | 0.2–1.0 g/L |
| Industrial and Household Cleaning | Metal degreasing, hard surface cleaning, CIP cleaning of food equipment | Emulsifying mineral oils, paraffin wax, and animal and vegetable fats to form stable O/W emulsions | Adjust according to formulation, often used with soda ash or phosphates |
| Cosmetics and Personal Care | Emulsification and solubilization in creams, lotions, shampoos, body washes, and makeup removers | O/W emulsifier and solubilizer, stabilizing oils, fragrances, and other water-insoluble ingredients | 0.5%–5.0% |
| Papermaking Industry | Pulp wetting, fiber dispersion, coating auxiliaries | Reducing surface tension of pulp, promoting uniform fiber dispersion, improving paper formation and coating gloss | Adjust according to process conditions |
| Pesticide Formulation Processing | Preparation of EW, ME, and WP formulations | Nonionic emulsifier and wetting penetrant, enhancing spreading and stability of the formulation | Compounded with anionic emulsifiers, ratio depends on the active ingredient |
