2. Physical and Chemical Properties
Physical Indicators
- Appearance: Colorless transparent viscous liquid
- Odor: Odorless, slight sweet taste
- Solubility: Fully miscible with water, ethanol, methanol, acetone and glycerin; slightly soluble in aromatic hydrocarbons; insoluble in aliphatic mineral oil
- Melting Point: -7 °C
- Boiling Point: 285–290 °C (760 mmHg)
- Density (20 °C): 1.120–1.125 g/cm3
- Refractive Index (20 °C): 1.454–1.456
- Flash Point: 165 °C
- Hygroscopicity: Strongly hygroscopic under high humidity environment
- Aqueous Stability: Stable under neutral, weakly acidic and weakly alkaline aqueous systems; no hydrolysis at room temperature
Chemical Characteristics
- Molecular Structure: Linear polyether diol containing two terminal -OH groups and two ether bonds
- Core Functional Mechanism: Polar polyether humectant with excellent water locking performance; high boiling point low volatility solvent; raw material for polyester, polyurethane and esterification synthesis
- Photostability: Stable under sealed light storage; no obvious discoloration
- Thermal Stability: Stable below 230 °C; prolonged heating above 260 °C triggers dehydration and ether degradation
- Chemical Compatibility: Compatible with most surfactants, cosmetic oils and resin monomers; incompatible with strong oxidants and concentrated strong alkalis under high temperature
3. Main Application Fields
- Core Application: Cosmetic Humectant & Solvent
Moisturizing agent and solubilizer for skin care lotion, hair serum and essence; improves skin hydration and dissolves oil-soluble active ingredients - Industrial High-Boiling Solvent
Solvent for printing ink, coating, printing dye and textile printing paste, enhances leveling performance - Refrigeration & Antifreeze Raw Material
Component of high-temperature resistant antifreeze fluid for industrial equipment and air conditioning systems - Polyurethane & Polyester Synthetic Intermediate
Diol monomer for synthesizing waterborne polyurethane, polyester plasticizers and polyether surfactants - Gas Drying Agent
Desiccant auxiliary for natural gas and industrial gas dehydration treatment
4. Platform Category & Product Group Guidance
1) Domestic B2B Platform Category
Recommended Path: Organic Intermediates / Cosmetic & Industrial Solvents
Reason: Triethylene glycol polyether diol widely used in daily chemical moisturizer, coating solvent and polymer synthesis
2) English Product Group Dropdown Options
