PEG-1000/1500 is a nonionic polyethylene glycol series product produced by Haian Guoli Chemical Co., Ltd. It appears as a white waxy solid or flake with a defined molecular weight distribution range (PEG-1000 or PEG-1500 optional). With its excellent emulsifying and dispersing properties, outstanding wetting and solubilizing capabilities, superior chemical stability, and good biocompatibility, this product has become an indispensable functional additive in multiple industries.
In cosmetics and pharmaceuticals, PEG-1000/1500 is widely used due to its low toxicity (extremely low acute oral toxicity) and good skin compatibility; in industrial manufacturing, its acid-alkali resistance, hard water resistance, chemical stability, and thermal stability allow it to maintain stable performance across a wide pH range and processing temperature conditions, making it an ideal lubricant, mold release agent, and heat transfer medium.
The following section details the specific application processes and functional roles of PEG-1000/1500 from six industry dimensions, providing references for formulation development and process optimization.
| Industry Sector | Application Process/Functional Role | Functional Principle and Effect |
|---|---|---|
| Cosmetics & Personal Care | Moisturizer | Forms hydrogen bonds with water molecules to lock in moisture, keeping skin and hair hydrated |
| Lubricant / Softener | Reduces friction coefficient between components, imparting a silky feel and soft touch | |
| Formula Stabilizer | Used in creams, lotions, cleansers, and hair products to enhance stability and user experience | |
| Pharmaceutical Industry | Ointment Base | Water-soluble base component, easy to wash off, does not affect skin physiological function, good drug compatibility |
| Suppository Base | Melts rapidly at body temperature to release the drug, with water absorption and dispersion capabilities | |
| Binder (Wet Granulation) | Provides good binding force, ensures uniform and compact granules for tableting | |
| Coating Material (Plasticizer/Pore Former) | Adjusts flexibility, solubility, and permeability of film or sugar coatings | |
| Dropping Pill Base | Acts as a carrier material, melts and then cools to form uniform spherical pills | |
| Industrial Manufacturing | Lubricant | Reduces friction in metalworking and plastic molding, decreasing equipment wear and energy consumption |
| Mold Release Agent | Forms an isolation film in injection molding and die casting, ensuring smooth release and surface finish | |
| Hot Melt Adhesive Modifier | Adjusts viscosity and open time, improving flowability and bond strength | |
| Heat Transfer Medium | Used in constant temperature baths or heat exchange systems, wide temperature range, non-toxic and non-corrosive | |
| Textile Industry | Sizing Agent | Forms a flexible film on warp yarns during sizing, enhancing yarn strength and abrasion resistance, reducing breakage during weaving |
| Antistatic Agent | Imparts conductivity and hygroscopicity to fiber surfaces, rapidly dissipating static charges | |
| Rubber Industry | Release Agent | Coated on unvulcanized rubber or raw rubber sheets to prevent sticking, facilitating handling and storage |
| Vulcanization Accelerator Carrier | Acts as a dispersion medium for accelerators, ensuring uniform distribution in the rubber compound, improving vulcanization efficiency and product uniformity | |
| Inks and Coatings | Plasticizer | Increases flexibility and elasticity of resin systems, preventing cracking during bending or temperature changes |
| Dispersant | Promotes uniform dispersion of pigments and fillers, preventing flocculation and sedimentation, enhancing tinting strength and hiding power | |
| Flow Control Agent | Adjusts rheological properties, improving leveling and wetting, reducing brush marks and surface defects |
