application area
1. Food additive: Stearol is used as a sweetener and humectant to increase flavor and extend shelf life in food processing. Octadecyl alcohol can form glyceride with fatty acids, and is used to make chocolate, candy, dessert, frozen food, etc.
2. Textile industry: Octadecyl alcohol can also be used as dye solvent and coating additive in textile industry to improve the quality of dyeing and coating.
3. Pharmaceutical manufacturing: Stearol has been used in controlled release tablets, suppositories, suppositories, and also has been studied as a transdermal penetration enhancer.
4. Daily chemical industry: Stearyl alcohol is commonly used in cosmetics. By increasing the viscosity of emulsion, it increases its stability. Stearol also has certain emollient and weak emulsifying properties, which can be used to improve the water retention capacity of ointment, such as Van's.
Packaging method
Cowhide bag
