Properties and stability
It does not decompose under normal temperature and pressure. Contact with strong oxidants is prohibited.
Storage method
1. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. should be kept away from oxidizer, do not store together.
2. Equip with corresponding varieties and quantities of fire-fighting equipment. The storage area should be equipped with emergency release equipment and suitable containment materials.
Synthesis method
1. Squalane is produced by hydrogenation of squalene. Squalene is found in the livers of blue whales and sharks. It can be obtained by extraction and then refined to obtain squalene.
Purpose
1. Gas chromatography stationary solution (maximum operating temperature 150°C, solvent is toluene), separates and analyzes gaseous hydrocarbons and light fraction liquid hydrocarbons (C1～C8 ) lubricant. Transformer oil.
2. Squalane is less irritating to the skin and can make the skin soft. It itself or combined with other raw materials is very inert. , so it is an extremely stable oil raw material. Compared with mineral oil-based alkanes, it has a less greasy feel and has good skin permeability, lubricity and safety. It can be used as cream, lotion, lotion, etc. in cosmetics. Oil-based raw materials for lipstick and hair care products. The addition amount is 0.1%~50%.
