introduction | isopropyl myristate is colorless to light yellow thin oily liquid, odorless and tasteless. Soluble in ethanol, ether, chloroform. Can be miscible with water. It has good lubricity and permeability, and can improve the affinity for the skin. It is a lower alcohol ester of higher fatty acids. |
application | isopropyl myristate has low greasy feeling, softens the skin, and has good permeability. it is a solvent and retention agent for pigments, spices and various additives. Low melting point, stable and not easy to hydrolyze, color and smell can meet the requirements of cosmetics, is commonly used in cosmetics of excellent ester raw materials. |
content analysis | accurately weigh about 1.5g of sample, and then determine according to ester determination method (OT-18). The equivalent factor (e) in the calculation is 135.2. Or by gas chromatography (GT-10-4) with non-polar column method. |
toxicity | ADI is not specified (FAO/WHO,2001). |
use | used as a dispersant for lipstick, hair cream, lipstick, cleaning cream, incense powder and medical ointment, and can also be used as a perfume fixative. It is suitable for use as a dispersant in cosmetics and pharmaceutical industries, and as a fixative for perfume. Carrier solvent. GB 2760-96 specifies food spices that are allowed to be used. is one of the important additives of high-grade cosmetics, which has excellent penetration, moisturizing and softening effects on the skin. It is used as an emulsifier and wetting agent for cosmetics. Used in organic synthesis. Solvent. Prepare spices oily raw materials for cosmetics and solvents for pesticides. Widely used as additives for advanced cosmetics such as creams, creams, and conditioners |
production method | obtained by esterification of myristic acid and isopropanol after resteaming coconut oil. 200 kg of 14 acid and 450 kg of isopropanol are sequentially added into the reaction kettle, 360kg(98%) sulfuric acid is added after mixing, heated and refluxed for 10 h, isopropanol is recovered, acid is washed with ice water, neutralized with 10% Na2CO3 aqueous solution, isopropanol and water are evaporated under normal pressure, and the product is evaporated at 185 ℃/2.0 kPa ~ 195 ℃/2.7 kPa under reduced pressure. 90 kg of isopropanol is added into the reaction kettle, and then 5% of the total amount of sulfuric acid is added as catalyst. Under stirring, 228 kg of decadecanoic acid is slowly added, heated and refluxed, and the water is continuously divided into water. After the reaction is reached without water, the acid value is measured by cooling and sampling, and the acid value reaches 1.5 mg KOH/g as the end point. Add alkali to neutralize, remove water under reduced pressure, and dealcohol to an acid value of 0.05~1.0 mg KOH/g under reduced pressure. The discharge is the finished product. |
