Product Introduction
PEG-1000 (Polyethylene Glycol 1000) is a water-soluble polymer synthesized through the polymerization of ethylene oxide, with an average molecular weight of approximately 1000. Its chemical structure is HO-(CH₂CH₂O)ₙ-H, combining hydrophilicity and flexibility, making it widely applicable in pharmaceuticals, cosmetics, industrial lubrication, textiles, and other fields.
Product Characteristics
Solubility: Easily soluble in polar solvents such as water, ethanol, and glycerol; insoluble in oils.
Stability: Chemically stable, resistant to acids, alkalis, and high temperatures (≤200°C).
Safety: Non-toxic and non-irritating, compliant with pharmaceutical and cosmetic-grade standards (e.g., USP/EP).
Compatibility: Compatible with various organic and inorganic substances, serving as a solvent, thickener, or carrier.
Product Applications
Pharmaceutical Industry
Drug Formulations: Used as a water-soluble matrix for suppositories, ointments, and pills to enhance drug solubility and controlled release.
Wetting Agent: Adjusts viscosity in eye drops and injectables to improve comfort.
Protein Stabilizer: Protects the activity of biologics (e.g., vaccines, antibodies).
Cosmetics and Personal Care
Humectant: Locks in moisture in lotions and creams, improving skin texture (e.g., "smooth, non-greasy" feel).
Thickener: Modifies the rheological properties of shampoos and body washes.
Solvent: Dissolves fragrances or active ingredients (e.g., salicylic acid).
Industrial Applications
Metalworking Fluids: Serves as a base component in water-based lubricants to reduce friction and wear.
Textile Auxiliaries: Acts as a dispersant in fiber dyeing to enhance dye uniformity.
3D Printing: Functions as a soluble support material (e.g., PVA alternative).
Other Applications
Laboratory Research: Osmotic pressure regulator in cell culture.
Agriculture: Adjuvant for pesticides to improve active ingredient adhesion on leaves.
