Hydrogenated Castor Oil Polyoxyethylene Ether HEL-40 (CAS No.: 61788-85-0) is a nonionic surfactant derived from natural hydrogenated castor oil through ethoxylation. It appears as a light yellow paste to viscous liquid. With its excellent comprehensive performance in emulsification, solubilization, wetting, and dispersion, as well as good tolerance to acidic/alkaline environments and hard water, this product plays a key role in multiple industrial fields.
In cosmetic formulations, HEL-40 serves as a mild O/W emulsifier and efficient solubilizer, evenly dispersing fragrances, essential oils, and oil-soluble active ingredients in aqueous systems to prepare transparent and stable makeup removers, skincare lotions, and shampoo/body wash products. In the textile industry, it is used as a leveling agent, softener, and antistatic finishing agent, significantly improving the uniform dispersion of dyes on synthetic fibers and their blends, imparting a soft and smooth feel to fabrics.
In industrial applications, this product combines emulsifying and lubricating functions, suitable for formulating semi-synthetic and emulsion-type cutting fluids and grinding fluids, providing cooling while forming a lubricating film to reduce friction. In hard surface cleaning, as a low-foaming nonionic surfactant, it rapidly emulsifies and removes grease and oil stains, commonly used in kitchen heavy-duty degreasers and multi-purpose cleaning formulations. In pesticide formulations, HEL-40 acts as an emulsifying dispersant, significantly improving the dispersion stability and emulsification performance of active ingredients in liquid formulations such as emulsifiable concentrates (EC), microemulsions (ME), and oil-in-water emulsions (EW), ensuring even spraying and efficacy.
| Industry Sector | Application Role | Typical Process/Product |
|---|---|---|
| Cosmetics and Personal Care | O/W emulsifier, solubilizer, emollient | Creams, lotions, makeup removers, facial cleansers, shower gels, transparent aqueous systems |
| Textile Printing and Dyeing Auxiliaries | Leveling agent, softener, antistatic finishing agent | Dyeing of synthetic fibers, finishing of blended fabrics |
| Metalworking Fluids | Emulsifier, lubricating component | Semi-synthetic cutting fluids, emulsion-type cutting fluids, grinding fluids |
| Industrial and Household Hard Surface Cleaning | Low-foaming nonionic surfactant | Kitchen heavy-duty degreasers, general hard surface cleaners, multi-purpose cleaning formulations |
| Pesticide Formulations | Emulsifying dispersant | Emulsifiable concentrates (EC), microemulsions (ME), oil-in-water emulsions (EW) and other liquid formulations |
In cosmetic formulations, HEL-40 is especially suitable for transparent aqueous makeup removers and essential oil-containing formulations due to its strong solubilizing capacity and low irritation. In textile processes, it is recommended to be used in combination with anionic or cationic auxiliaries to achieve optimal synergistic effects. In metalworking fluid formulations, HEL-40 can be used together with other lubricating additives and rust inhibitors to enhance overall processing performance. For pesticide formulations, this product performs excellently in emulsifiable concentrates and oil-in-water emulsions, effectively reducing crystallization of active ingredients and extending the shelf life of the formulation.
