Palmitic Acid
Saturated fatty acid with 16 carbons. One of the baseline components of the skin's lipid mantle (approximately 20% of stratum corneum fatty acids). In cosmetics it is used as an emulsifier component and emollient. Also found in palm-oil-based soaps. At excess concentration it can leave a heavy film feel.
