Isopropyl Myristate

Isopropyl myristate (IPM) is the ester of myristic acid (tetradecanoic acid) and isopropanol, with molecular formula C17H34O2 and molecular weight 270.45, CAS number 110-27-0. At room temperature it is a colorless to pale yellow clear oily liquid, melting at 3°C and boiling at 193°C, with a relative density (25/25°C) of 0.846-0.854 and a refractive index (20°C) of 1.432-1.436 (see specifications); it is insoluble in water and miscible with organic solvents. The iodine value is ≤1.0 g I₂/100g and the acid value ≤1.0 (see specifications) - the iodine value reflects the unsaturated-bond content of the molecule, and this product is a low-iodine-value saturated fatty acid ester. In the industry it is used as an emollient ester raw material; literature-reported skin-feel conditioning and topical-formulation carrier uses are described by industry below. This page lists release-control items only; this product is not registered as a pharmaceutical excipient, and suitability for pharmaceutical use must be assessed by the buyer under applicable drug regulations.

Downstream applications include cosmetics, personal care and topical formulation directions. In creams, lotions and body oils it serves as an emollient ester raw material; literature-reported skin-feel conditioning uses include improving spreadability and reducing the greasy feel of formulations (per public literature; finished-product skin feel is verified in each formula). Where the end product contacts the skin, compliance follows the target market's regulations, and buyers are responsible for confirming use compliance. Published literature also reports research on its use as an active-ingredient carrier and in penetration enhancement in topical formulations (research-direction use, per public literature).

Downstream applications include use as an emollient ester raw material in skin creams, lotions and body oils. Literature-reported skin-feel conditioning uses include improving spreadability and reducing the greasy feel of formulations (per public literature; finished-product skin feel is verified in each formula) (for cosmetic uses: permitted uses and limits follow the target market's current regulations). With a melting point of 3°C (see specifications) the product is a liquid oil at room temperature and can be metered directly into cold-processing (cold-processing suitability is verified in the actual formulation); assay (as C17H34O2) ≥90.0 and moisture ≤0.10% (see specifications) can be checked item by item against this page when selecting.

The product is miscible with organic solvents and insoluble in water (see specifications); in the industry it is used as a solvent or fragrance-carrier raw material in perfume and personal care formulations, and published literature also reports its use as a carrier for active ingredients (per public literature). Where the end product contacts the skin, compliance follows the current regulations of the target market, and buyers are responsible for confirming use compliance.

The product is used in topical drug formulations for emollient, solvent and penetration-enhancement directions; published literature also reports research on penetration enhancement (research-direction use, per public literature). Where the downstream application is pharmaceutical, registration and compliance requirements are assessed and confirmed by the buyer under applicable drug regulations.
