What is the Difference Between Isopropyl Myristate and Isopropyl Palmitate?

Isopropyl myristate and isopropyl palmitate are both ester compounds used in the personal care industry, but they have different properties and applications. The key difference between the two is the type of fatty acid they are derived from: isopropyl myristate (IPM) is derived from myristic acid (C14), while isopropyl palmitate (IPP) is derived from palmitic acid (C16).

Isopropyl Myristate:

• Functions as an emollient and lubricant
• Used in various personal care products, such as pre-shaves, aftershaves, shampoos, bath oils, antiperspirants, deodorants, creams, and lotions
• Has a low viscosity and is a lightweight emollient
• Exists in a liquid state at room temperature with a molecular mass of 270.457 g/mol
• Can be used as a carrier oil in some applications

Isopropyl Palmitate:

• Functions as a thickening agent and emollient
• Used in cosmetics, such as moisturizers, where it forms a thin layer and easily penetrates the skin
• Enhances silkiness in hair and skin
• Has a higher viscosity compared to isopropyl myristate

In summary, isopropyl myristate and isopropyl palmitate are both ester compounds used in personal care products, but they have different properties and applications. Isopropyl myristate is a lightweight emollient, while isopropyl palmitate serves as a thickening agent and emollient, providing silkiness to hair and skin.
