2-Ethylhexyl Salicylate
1. Basic Information
Name: 2-Ethylhexyl salicylate
Alias: Octisalate, Salicylic acid 2-ethylhexyl ester
CAS No.: 118-60-5
Molecular Formula: C??H??O?
Molecular Weight: 250.33
Category: Cosmetic UVB sunscreen raw material, aromatic ester flavor intermediate, plasticizer, daily chemical additive
2. Physical and Chemical Properties
Physical Properties
- Appearance: Colorless to pale yellow transparent oily liquid
- Odor: Faint mild balsamic sweet aroma
- Solubility: Miscible with ethanol, isopropanol, mineral oil, vegetable oil and cosmetic solvents; insoluble in water, glycerin
- Boiling Point: 189–191 °C (10 mmHg)
- Density (20 °C): 1.013–1.019 g/cm3
- Refractive Index nD20: 1.490–1.494
- Flash Point: 132 °C
- Hygroscopy: Non-hygroscopic
- Aqueous property: Weakly acidic aromatic ester; stable in neutral water, hydrolyzes under strong acid/alkali heating to salicylic acid and 2-ethylhexanol
Chemical Properties
- Molecular structure: Ester formed by salicylic acid and 2-ethylhexanol, contains phenolic hydroxyl group and benzene ring conjugated system, has strong UVB absorption capacity
- UV absorption characteristic: Effective UVB filtering agent with absorption peak at 305 nm, widely used in sunscreen formulations
- Ester hydrolysis: Long-term heating with strong base will break ester bond to release salicylic acid; phenolic hydroxyl can form complexes with metal ions
- Photostability: Moderate light stability; long-term intense UV irradiation slightly reduces UV absorption efficiency
- Thermal stability: Stable below 150 °C; high-temperature overheating produces slight phenolic decomposition odor
- Compatibility: Excellent compatibility with sunscreen oil phases, silicone oils and cosmetic emulsifiers; incompatible with strong alkali and heavy metal salts
3. Main Application Fields
1. Cosmetic Sunscreen Raw Material (Core Application)
Classic oil-soluble UVB filter, added to sunscreen lotion, cream, spray and daily skin care products to block ultraviolet B rays and prevent sunburn
2. Fragrance Fixative Intermediate
Mild long-lasting balsamic fragrance fixative for perfume, shower gel and soap formulas
3. Plastic & Coating Auxiliary
Low-volatility plasticizer for PVC and cellulose resin, improves coating flexibility
4. Organic Synthesis Reagent
Raw material for preparing salicylic acid derivative fine chemicals
