Polyethylene Glycol Distearate 400DS (PEG-400 Distearate, CAS No.: 9005-08-7) is a non-ionic surfactant produced by Haian Guoli Chemical Co., Ltd., appearing as a white to slightly yellow waxy solid. Its molecular structure consists of a hydrophilic polyethylene glycol (PEG-400) segment and a lipophilic stearate ester group. This unique amphiphilic structure endows the product with excellent surface activity and interfacial control capabilities.
As a non-ionic surfactant, the core advantage of this product lies in its excellent chemical compatibility. It can be smoothly compounded with anionic, cationic, and amphoteric surfactant systems without failure due to charge conflicts. At the same time, the product maintains stable performance over a wide pH range and in hard water environments without precipitation, making it perform excellently under demanding formulation conditions. Additionally, the product is mild to the skin with low irritation, making it an ideal choice for personal care formulations.
In terms of environment and safety, Polyethylene Glycol Distearate 400DS has the characteristic of being readily biodegradable, meeting OECD 301 series ready biodegradability standards, with low bioaccumulation potential and minimal cumulative environmental impact. According to GHS hazard classification, this product does not meet the classification thresholds for any hazard category, with an oral LD50 greater than 2000 mg/kg, no significant skin irritation or sensitization, and is classified as a low-risk chemical.

Personal Care and Cosmetics: As a primary emulsifier, co-emulsifier, and thickener, widely used in creams, lotions, conditioners, shampoos, body washes, sunscreens, and facial cleansers, imparting an ideal consistency, spreadability, and fine skin feel. Recommended dosage depends on the formulation system, typically 1%-5%.
Household and Industrial Detergents: Used as a thickener and foam stabilizer in laundry liquids, dishwashing detergents, fabric softeners, and hard surface cleaners, improving cling and low-temperature stability while enhancing the washing feel.
Textile Auxiliaries: Used as a key component of softeners, antistatic agents, and lubricants, helping active ingredients adhere uniformly to fiber surfaces, imparting a soft and fluffy hand feel to fabrics and reducing static buildup during production.
Metalworking Fluids: Acts as an efficient emulsifier and lubricating additive in cutting fluids, grinding fluids, emulsifiable oils, and rust preventives, promoting stable dispersion of oil-water systems, providing boundary lubrication, extending tool life, and improving workpiece surface finish.
Plastic and Rubber Processing: Serves as an internal lubricant and mold release agent, reducing friction between polymer melts and processing equipment, improving filler dispersion in resins, enhancing product surface quality, and reducing mold fouling.
