Application Fields

1. Food Additive: Stearyl alcohol is used as a sweetener and humectant, enhancing flavor and extending shelf life in food processing. It can form glycerides with fatty acids for use in chocolate, candy, desserts, and frozen foods.

2. Textile Industry: Stearyl alcohol serves as a dye solvent and coating additive in the textile industry to improve the quality of dyeing and coatings.

3. Pharmaceutical Manufacturing: Stearyl alcohol has been used in controlled-release tablets, suppositories, and is also studied as a transdermal penetration enhancer.

4. Daily Chemical Industry: Stearyl alcohol is commonly used in cosmetics to increase the viscosity of emulsions, thereby enhancing stability. It also has mild emollient and weak emulsifying properties, used to improve the water retention capacity of ointments, such as Vaseline.

Packaging Method

Kraft Bag

Stability and Storage Conditions

Store stearyl alcohol in a cool, well-ventilated warehouse away from ignition sources and heat. Protect from direct sunlight. Keep containers sealed. Separate from oxidizers, acids, acid anhydrides, and acyl chlorides. Do not store together. Equip with appropriate types and quantities of fire-fighting equipment. The storage area should have leak emergency handling equipment and suitable containment materials.
