Polyethylene Glycol Distearate 400DS (CAS No.: 9005-08-7) is produced via the esterification reaction of polyethylene glycol with stearic acid. It appears as a white to slightly yellow waxy solid. Its nonionic nature gives the product excellent chemical compatibility, allowing it to be smoothly compounded with anionic, cationic, and amphoteric systems, maintaining stable performance across a wide pH range and in hard water conditions, making it highly favored in numerous industrial formulations.
With its outstanding emulsifying performance (efficiently reducing oil/water interfacial tension to prepare stable oil-in-water emulsions), superior dispersing ability (excellent dispersion and suspension effects for solid particles and pigments), and mild, low-irritation characteristics, this product has become a key functional component in formulations across multiple industries. Below is a detailed introduction to its main application industries and corresponding processes.
| Application Industry | Specific Application Areas | Process Role & Function |
|---|---|---|
| Personal Care & Cosmetics | Creams, lotions, conditioners, sunscreens, shampoos, body washes, facial cleansers | Primary emulsifier, co-emulsifier, and thickener, imparting ideal consistency, fine texture, good spreadability, and a moisturizing skin feel |
| Household & Industrial Detergents | Laundry liquids, dishwashing detergents, hard surface cleaners, fabric softeners, liquid detergents | Thickener, foam stabilizer, and conditioner, enhancing product cling and user experience, maintaining system stability at low temperatures, and improving rinsing feel |
| Textile Auxiliaries | Softening agents, antistatic agents, finishing agents | Emulsifying and dispersing component, helping active ingredients uniformly adhere to fiber surfaces, imparting a soft, fluffy hand feel to fabrics, and reducing static buildup during production |
| Metalworking Fluids | Cutting fluids, grinding fluids, emulsifiable oils, rust preventatives | Efficient emulsifier and lubricant additive, promoting stable oil-water system dispersion, providing boundary lubrication performance, extending tool life, and improving workpiece surface finish |
| Plastics & Rubber Processing | Polymer processing, filled modification, mold forming | Internal lubricant and mold release agent, reducing friction between melt and processing equipment, improving filler dispersion in resin, enhancing product surface finish without affecting transparency, and reducing mold fouling |
In formulation design, it is recommended to use Polyethylene Glycol Distearate 400DS as a multifunctional additive: In personal care formulations, it can synergize with various ionic surfactants, functioning as a primary or auxiliary emulsifier to improve cream and lotion stability; In metalworking fluid formulations, it is recommended for emulsifying and dispersing oil-water systems to provide reliable boundary lubrication; In plastic processing, adding an appropriate amount of this product can significantly improve melt flowability and mold release performance.
Due to its excellent resistance to acids, alkalis, and hard water stability, this product is particularly suitable for industrial formulations with wide pH ranges and complex water quality conditions. Its nonionic nature means it is virtually unaffected by other ionic components in the system during compounding, offering extremely high formulation flexibility.
