Methyl Soyate

What is Methyl Soyate?

Methyl soyate is a fatty acid methyl ester derived from soybean oil through transesterification with methanol, resulting in a clear, low-odor liquid composed mainly of methyl oleate, linoleate, and other soy-derived fatty acid chains. Primarily used in cosmetic formulations like moisturizers, lotions, and serums within the emollient category, it functions by spreading evenly on the skin to mimic natural sebum. This creates a lightweight barrier that enhances product slip, fills minor surface imperfections for a smoother feel, and supports the skin's lipid matrix to minimize water evaporation without heaviness. Its compatibility with other ingredients improves overall formula stability and sensory appeal, making it suitable for daily skincare routines focused on hydration and texture refinement.
