Isopropyl myristate Usage And Synthesis
- Chemical PropertiesIt is a colorless and odorless liquid, and miscible with vegetable oil. It is not easy to be either hydrolyzed or become rancid. The refractive index nD20 is 1.435~1.438, and the relative density (20°C) is 0.85~0.86.
- Content AnalysisWeight 1.5 g sample. Then it is determined by the method ester assay (OT-18). The equivalent factor (e) in the calculation is 135.2. Or it is determined by a non-polar column method of gas chromatography (GT-10-4).
- It is applied as a dispersant for lipstick, hair cream, lipstick, cleansing cream, fragrance powder and medical ointment and can be also used as perfume fixative.
- It is applied as dispersant for cosmetics.
- Carrier solvent. Allowed food flavor additive according GB 2760-96.
- It is one of the important ingredients of high-end cosmetics, has excellent penetration into the skin, moisture and softening effect and is used as emulsifier and wetting agent for cosmetics.
- Used for organic synthesis. As solvent. For the preparation of spices.
- Oily raw materials of cosmetics, solvent for pesticide original drugs.
- It is widely used as additives for high-end cosmetics, such as ointment, cream, and conditioner.
- Production MethodIt is a product of esterification of myristic acid derived from re-steamed coconut coil with isopropyl alcohol.
(1) 200 kg myristic acid and 450 kg isopropyl alcohol were added into the reaction vessel in turn. After mixing, 360 kg sulfuric acid (98%) was added. The reaction mixture was heated to reflux for 10 hours. Isopropyl alcohol was then recovered, washed with ice water, and neutralized with Na2CO3 aqueous solution (10%). Under normal pressure, isopropyl alcohol and water were distilled. While under reduced pressure, isopropyl myristate was distilled (185°C/1.0kPa~195°C/2.7kPa).
(2) 90 kg isopropyl alcohol was added into the reaction vessel and then sulfuric acid as catalyst, with 5% of the total amount, was added. During mixing, 228 kg myristic acid was added slowly. The mixture was heated to reflux and water was continuously separated. Until no water was separated, the reaction temperature was reduced and probe was obtained to measure the acid value. When the acid value reached 1.5 mg KOH/g, the reaction was completed. Alkali was then added for neutralization. After the removal of water under reduced pressure, the pressure was further reduced for dealcoholization until the acid value was 0.05~1.0 mg KOH/g. The final product is then isopropyl myristate.

- Chemical Propertiescolourless liquid of low viscosity
- Chemical PropertiesIsopropyl myristate is a clear, colorless, practically odorless liquid of low viscosity that congeals at about 5°C. It consists of esters of propan-2-ol and saturated high molecular weight fatty acids, principally myristic acid.
- OccurrenceReported found in kumquat peel oil, papaya, starfruit, plum brandy, coriander seed and loquat
- UsesIsopropyl myristate is an emollient in cosmetic and pharmaceutical bases.
- UsesIn cosmetic and topical medicinal Preparations where good absorption through the skin is desired. A jellied isopropyl myristate was marketed as Estergel (Merck & Co.) .
- Usesisopropyl myristate is an emollient, moisturizer, binder, and skin softener that also assists in product penetration. An ester of myristic acid, it is naturally occurring in coconut oil and nutmeg. Although isopropyl myristate is generally considered comedogenic, some ingredient manufacturers clearly specify non-comedogenicity on their data sheets.
- Production MethodsIsopropyl myristate may be prepared either by the esterification of myristic acid with propan-2-ol or by the reaction of myristoyl chloride and propan-2-ol with the aid of a suitable dehydrochlorinating agent. A high-purity material is also commercially available, produced by enzymatic esterification at low temperature.
- PreparationBy conventional esterification of isopropanol with myristic acid
- brand nameEstergel (Merck).
- Pharmaceutical ApplicationsIsopropyl myristate is a nongreasy emollient that is absorbed readily
by the skin. It is used as a component of semisolid bases and as a
solvent for many substances applied topically. Applications in
topical pharmaceutical and cosmetic formulations include bath oils;
make-up; hair and nail care products; creams; lotions; lip products;
shaving products; skin lubricants; deodorants; otic suspensions; and
vaginal creams. For example, isopropyl myristate is a
self-emulsifying component of a proposed cold cream formula,
which is suitable for use as a vehicle for drugs or dermatological
actives; it is also used cosmetically in stable mixtures of water and
Isopropyl myristate is used as a penetration enhancer for transdermal formulations, and has been used in conjunction with therapeutic ultrasound and iontophoresis.It has been used in a water-oil gel prolonged-release emulsion and in various microemulsions. Such microemulsions may increase bioavailability in topical and transdermal applications. Isopropyl myristate has also been used in microspheres, and significantly increased the release of drug from etoposide-loaded microspheres.
Isopropyl myristate is used in soft adhesives for pressuresensitive adhesive tapes.
- Contact allergensDespite wide use in cosmetics, perfumes, and topical medicaments, isopropyl myristate is a very weak sen- sitizer and a mild irritant.
- PharmacologyIsopropyl myristate is used in pharmaceutical preparations because it improves
solubility and increases absorption through the skin. External uses include a non-irritating iodine
preparation for disinfecting the skin (Powers & Rieger, 1963) and aerosol bactericidal preparations
for feminine hygiene use without irritation of the skin and mucous membranes (Geistlich, 1970;
Watson. 1969). Preparations for internal use include oral steroid formulations (Hirata, 1970) and
anaesthetic injection solutions (Davis, Pearce & Connor, 1972).
Veterinary medications containing isopropyl myristate include oral or parenteral compositions for lungworm infections (N. V. Philips' Gloielampenfabrieken, 1964) and a spray formulation for bovine udders to treat mastitis, combat infection and improve the general skin condition (Kraus, 1965). Isopropyl myristate has been found to be an effective repository vehicle for im injection of penicillin in rabbits and for sc administration of oestrogens in ovariectomized rats (Platcow & Voss, 1954).
In assays on human forearms, vasoconstrictor activity of ointment preparations containing 0025% betamethasone 17-benzoate in white soft paraffin was increased by the presence of isopropyl myristate (Pepler, Woodford & Morrison, 1971). Donovan, Ohmart & Stoklosa (1954) noted that the good solvent properties of isopropyl myristate might increase the therapeutic activity of formulations by the apparent alteration in particle size of the active ingredients, so that further evaluation and clinical study would be necessary before its use in extemporaneous compounding could be recommended. Studies in which the antifungal activity of paraben esters solubilized by surfactants was decreased by isopropyl myristate (Matsumoto & Aoki, 1962) indicate that the effectiveness of medicinal substances may be influenced by the presence of surfactants and oily ingredients such as isopropyl myristate.
- SafetyIsopropyl myristate is widely used in cosmetics and topical
pharmaceutical formulations, and is generally regarded as a
nontoxic and nonirritant material.
LD50 (mouse, oral): 49.7 g/kg
LD50 (rabbit, skin): 5 g/kg
- MetabolismHigher molecular weight aliphatic esters are thought to be readily hydrolysed to the corresponding alcohols and acids which are then metabolized; isopropyl myristate is undoubtedly hydrolysed to normal metabolic products (Fassett, 1963). When myristic acid (as the ethyl ester) was fed to dogs,
- storageIsopropyl myristate is resistant to oxidation and hydrolysis, and does not become rancid. It should be stored in a well-closed container in a cool, dry place and protected from light.
- IncompatibilitiesWhen isopropyl myristate comes into contact with rubber, there is a drop in viscosity with concomitant swelling and partial dissolution of the rubber; contact with plastics, e.g. nylon and polyethylene, results in swelling. Isopropyl myristate is incompatible with hard paraffin, producing a granular mixture. It is also incompatible with strong oxidizing agents.
- Regulatory StatusIncluded in the FDA Inactive Ingredients Database (otic, topical, transdermal, and vaginal preparations). Used in nonparenteral medicines licensed in the UK. Included in the Canadian List of Acceptable Non-medicinal Ingredients.
