Isopropyl myristate is easily absorbed through the skin, leading to its use by cosmetic manufacturers.
Isopropyl myristate is a synthetic oil widely used in the cosmetic and pharmaceutical industries as a lubricant, emollient, and as a non-toxic alternative for lice control. The oil is made by condensing myristic acid with isopropyl alcohol and is colorless with a mild odor. It is easily absorbed by the skin and reduces the oily nature of cosmetics while giving them a smooth, transparent feel. Additionally, it is commonly used as an additive in oral care products such as mouthwashes. While generally considered safe, isopropyl myristate can cause mild allergic reactions and aggravate skin conditions such as acne.
Isopropyl myristate can be used as a non-pesticide alternative for the treatment of head lice.
This multi-purpose oil is an ester of isopropyl alcohol and myristic acid. The isopropyl component is a derivative of propane; Myristic acid is a fatty acid common in plant sources such as nutmeg and palm kernels. The oil has several unique characteristics that make it a valuable additive in many cosmetics and pharmaceuticals. Undoubtedly one of the most significant is the ease of absorption by the skin. Used as an emollient in creams and lotions, isopropyl myristate ensures fast and deep penetration.

However, this deep penetrating feature has a drawback; Extensive use of oil-containing products can lead to clogged pores. However, it remains a valuable absorption vehicle and is a common component of moisturizers, bath oils, and lotions. Although it is an oil, it also reduces oiliness in cosmetics. When added to lip products and creams, it gives cosmetics a smooth, transparent texture without an oily feel.

Isopropyl myristate is also a common ingredient in pharmaceutical formulations. It is often used as a non-pesticide alternative to treat lice infestations, destroying the waxy coating that insulates lice and causes death from dehydration. It is also effective in controlling oral bacteria and is used in various mouthwash products.
Despite Isopropyl Myristate’s status as a non-carcinogenic and non-toxic substance, cases of allergic reactions occasionally occur. Those who suffer from acne should avoid using products that contain oil, as it has been shown to worsen the condition in some cases. People with naturally oily skin should also be aware of the potential pore-clogging side effect of prolonged exposure. Children under the age of four should not be given oil-containing products, and those with generally sensitive skin should also avoid it.
