Application areas

Application areas	Application Notes
food additives	Stearyl alcohol is used as a sweetener and humectant, enhancing flavor and extending shelf life during food processing. Octadecyl alcohol can form glycerides with fatty acids, used in the production of chocolate, candy, desserts, and frozen foods.
Textile industry	Octadecyl alcohol can also be used as a dye solvent and coating additive in the textile industry to improve the quality of dyeing and coating.
Pharmaceutical manufacturing	Stearyl alcohol has been used in controlled-release tablets , suppositories, and has also been studied as a transdermal permeation enhancer.Octadecyl alcohol is also used as a solvent and carrier in the preparation of some injectable and oral drugs. Its good solubility and low toxicity make it an ideal pharmaceutical excipient.
Daily chemical industry	Stearyl alcohol is commonly used in cosmetics . By increasing the viscosity of emulsions, it enhances their stability. Stearyl alcohol also possesses certain emollient and mild emulsifying properties, making it useful for improving the water-retention capacity of ointments, such as Vaseline .Octadecyl alcohol can effectively moisturize and absorb moisture from the skin, prevent dryness and cracking, and help keep the skin soft and smooth.

Packaging
