Introduction

Isopropyl myristate is a colorless to pale yellow thin oily liquid, odorless and tasteless. Soluble in ethanol, ether, chloroform. Miscible with water. It has good lubricity and permeability, and can improve the affinity to the skin. It is a lower alcohol ester of higher fatty acid.

Chemical properties

This product is a colorless, odorless liquid, miscible with vegetable oils. Not easy to hydrolysis and rancidity. Refractive index nD201.435～1.438, relative density (20℃) 0.85～0.86.

Use

●  It is used as a dispersant for lipstick, hair balm, lip balm, cleansing cream, powder and medical ointment. It can also be used as a perfume fixative.

●  It is suitable for use as a dispersant in the cosmetic and pharmaceutical industries, and as a fixative for perfume.

●  carrier solvent. GB 2760-96 stipulates that it is allowed to use spices for food.

●  It is one of the important added components of high-end cosmetics. It has excellent penetration, moisturizing and softening effects on the skin. It is used as an emulsifier and wetting agent in cosmetics.

●  for organic synthesis. solvent. Formulated spices

●  Cosmetics oily raw materials, pesticide technical solvent.

●  Widely used as an additive for high-grade cosmetics such as ointment, cream, conditioner, etc.

Production method

●  It is obtained by esterification of myristic acid and isopropanol obtained after re-steaming coconut oil.

●  200 kg of tetradecanoic acid and 450 kg of isopropanol were added to the reactor successively, 360 kg (98%) of sulfuric acid was added after mixing, heated to reflux for 10 h, the isopropanol was recovered, the acid was washed with ice water, and then 10% of Na CO was used. Neutralize with aqueous solution, steam isopropanol and water at atmospheric pressure, and steam the product under reduced pressure at 185 ℃/2.0 kPa～195 ℃/2.7 kPa.

●  90 kg of Virahol was added to the reactor, and then the sulfuric acid equivalent to 5% of the total feeding amount was added as a catalyst. Slowly add 228 kg of tetradecanoic acid under stirring, heat to reflux, and continuously separate water. After the reaction reaches no water, take samples to measure the acid value, and the acid value reaches 1.5 mg KOH/g as the end point. Add alkali for neutralization, remove water under reduced pressure, and then dealcohol under reduced pressure to an acid value of 0.05-1.0 mg KOH/g. The output is the finished product.
