PEG-1000/1500 (CAS No.: 25322-68-3) belongs to the Polyethylene Glycol series, with PEG-1000 and PEG-1500 corresponding to different molecular weight specifications. This product is a nonionic surfactant, exhibiting excellent physicochemical stability and broad compatibility, maintaining stable performance over a wide pH range.
In terms of functional characteristics, PEG-1000/1500 possesses outstanding emulsifying and dispersing properties, effectively reducing interfacial tension and promoting uniform mixing of oil and water phases; it also has good wetting and solubilizing capabilities, improving surface wettability of materials and increasing the solubility of poorly soluble substances. The product is resistant to acids, alkalis, and hard water, and is compatible with various organic solvents, surfactants, and polymer materials.
In terms of safety, PEG-1000/1500 has extremely low acute oral toxicity, making it suitable for applications with high safety requirements such as pharmaceuticals and cosmetics. However, it should be noted that it falls under GHS classification as Skin Irritation Category 2 (H315) and Eye Irritation Category 2 (H319). Appropriate protective equipment should be worn during handling to avoid direct contact with skin and eyes.

Note: For detailed technical parameters such as hydroxyl value, molecular weight distribution, and melting point range, no specific database details are available. It is recommended to contact the Guoli Chemical technical department to obtain the Certificate of Analysis (COA).
Cosmetics and Personal Care: Used as an efficient humectant and lubricant, it locks in moisture by forming hydrogen bonds with water molecules, imparting a silky feel and smooth skin sensation to products. Recommended for use in creams, lotions, facial cleansers, and hair care products to enhance formulation stability and user experience.
Pharmaceutical Industry: As an important pharmaceutical excipient, it can be used in ointment bases (water-soluble base, easy to clean), suppository bases (rapid melting at body temperature to release drugs), tablet binders (providing binding force in wet granulation), film-coating plasticizers, and pill matrices. Its good biocompatibility and chemical inertness ensure the safety and efficacy of preparations.
Industrial Manufacturing: Used as an efficient mold release agent and lubricant in rubber and plastic processing; reduces friction in metalworking; serves as a viscosity regulator for hot-melt adhesives; and can be used as a liquid heat transfer medium in constant temperature baths or heat exchange systems.
Textile Industry: Applied in warp sizing (enhancing yarn strength and abrasion resistance) and antistatic treatment (imparting conductivity and hygroscopicity to fiber surfaces, dissipating static electricity).
Inks and Coatings: Acts as a plasticizer to increase coating flexibility, as a dispersant to promote uniform pigment dispersion, and as a flow modifier to improve leveling.
