3. Application Scope and Usage
Hexadecanol C16 is primarily used in the cosmetics industry as an emollient and conditioning agent in skin care products such as lotions, creams, and lipsticks。It also serves as a plasticizer in plastics and rubbers, and as a lubricant in metalworking fluids. Additionally, it is used in the production of surfactants and as a raw material in the synthesis of various chemicals.
4. Package and Storage
Hexadecanol C16 is typically packaged in 25 kg or 50 kg drums with plastic linings to prevent moisture absorption. It should be stored in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. The storage temperature should not exceed 30°C to maintain product stability. Proper labeling and storage practices are essential to ensure safety and prevent contamination.
