Properties and stability

1. Stable under normal temperature and pressure. Transparent oily liquid, resistant to hydrolysis and rancidity, with good stability.

2. It is a good solvent for oils and fats, has good skin care effects, and has good affinity with the skin. Non-toxic, non-irritating, non-allergenic.

3. Exist in mainstream smoke.

Storage method

Packed in plastic drums or galvanized iron drums. Store in a cool, dry warehouse, away from fire and heat sources.

Synthesis method

1. Add 1 mol of hexadecanoic acid into the reaction kettle, add 1.5 mol of isopropanol, stir to dissolve, then add a catalyst amount of sulfuric acid and reflux for 10 hours under stirring, and evaporate excess isopropanol and water. Cool, add 5% Na2CO3 aqueous solution to neutralize, separate the water layer, and then dehydrate under reduced pressure to obtain the product.

2. Mainly adopt esterification method. It is obtained by esterification reaction of palmitic acid and isopropyl alcohol under heating conditions, followed by water washing, distillation and decolorization.


1. Can be used as an oil agent in skin care and hair care products. It can also be used as a solubilizer for flavors. It can be used as a decomposing suspending agent in beauty products to facilitate even application, leaving the skin feeling soft and increasing scratch resistance. Added to hair dyes, sunscreen oils and antiperspirants, it has a foam stabilizing effect. Used as emollient, greasy carrier, and solvent.

2.It is an excellent emollient, used in cosmetics, which can increase the spreadability of cosmetics and make the skin soft and non-greasy. It can be used for In formulas such as cream, foundation cream, lipstick, sunscreen oil, hair oil, mascara, eye shadow, etc.
