1,3-Butanediol
1. Basic Information
Name: 1,3-Butanediol
Alias: Butane-1,3-diol, 1,3-Butylene glycol
CAS No.: 107-88-0
Molecular Formula: C4H10O2
Molecular Weight: 90.12
Category: Cosmetic humectant, pharmaceutical solvent, flavor carrier, resin monomer, antifreeze raw material
2. Physical and Chemical Properties
Physical Properties
- Appearance: Colorless transparent viscous liquid
- Odor: Odorless, slight sweet taste
- Solubility: Fully miscible with water, ethanol, methanol, acetone; slightly soluble in ethyl acetate; insoluble in aliphatic hydrocarbons
- Boiling Point: 207–209 °C (760 mmHg)
- Density (20 °C): 1.004–1.008 g/cm3
- Refractive Index nD20: 1.439–1.442
- Flash Point: 121 °C
- Hygroscopy: Strongly hygroscopic, readily absorbs moisture from air
- Aqueous property: Neutral aliphatic diol, stable in neutral aqueous solution
Chemical Properties
- Molecular structure: Four-carbon straight chain with hydroxyl groups on C1 and C3, two active hydroxyl functional groups
- Esterification & etherification: Reacts with carboxylic acids to produce diol esters for plasticizers and cosmetic emollients; undergoes etherification to form low-irritant surfactants
- Polycondensation performance: Polymerizes with dicarboxylic acids to make polyester resins, waterborne coating binders
- Photostability: Excellent light resistance, no discoloration under long-term light exposure
- Thermal stability: Stable below 180 °C; prolonged high-temperature heating generates trace aldehyde impurities
- Compatibility: Compatible with most cosmetic raw materials, pharmaceutical excipients and polar solvents; incompatible with strong oxidants and concentrated strong acid under heating
3. Main Application Fields
1. Cosmetic Humectant (Core Application)
Low-irritation moisturizer added to lotion, cream, facial mask, shampoo; improves skin water retention, reduces product stickiness, enhances antibacterial preservation effect
2. Pharmaceutical Excipient & Solvent
Solvent for oral and external drug formulations; carrier for injections, ointments, improves drug solubility and skin penetration
3. Food & Fragrance Carrier
Solubilizer and fixative for edible flavors, extends fragrance retention time
4. Industrial Resin & Coating Raw Material
Monomer for water-based polyester, polyurethane coatings; low-temperature antifreeze agent for industrial circulating water
