Relative molecular mass: 522.96
1. Product Property
C16-18 alcohols, also known as cetearyl alcohol, are a mixture of fatty alcohols with an average carbon chain length of 16 to 18. They are colorless to pale yellow waxy solids with a mild characteristic odor. These alcohols are non-volatile and have a melting point range of 48-55°C. They are insoluble in water but soluble in organic solvents.
2. Quality Standard
| Parameter | Specification |
| Appearance | Colorless to pale yellow solid |
| Purity (GC) | ≥ 98.0% |
| Water content | ≤ 0.5% |
| Acid value | ≤ 0.5 mg KOH/g |
| Saponification value | 240-260 mg KOH/g |
| Iodine value | ≤ 2.0 g I₂/100g |
| Free fatty acids | ≤ 0.5% |
3. Application Scope and Usage
C16-18 alcohols are widely used in the cosmetic industry as emollients, thickeners, and stabilizers. They are also used in the production of surfactants, lubricants, and plasticizers. Additionally, they serve as intermediates in the synthesis of various chemicals and are used in the formulation of lotions, creams, and hair care products due to their skin conditioning properties.
4. Package and Storage
C16-18 alcohols are typically packaged in 25 kg or 50 kg plastic-lined drums. They should be stored in a cool, dry, and well-ventilated area away from direct sunlight and moisture. The storage temperature should not exceed 30°C. The drums should be kept sealed to prevent contamination and degradation. It is recommended to use the product within one year of purchase to ensure optimal quality and performance.
