| What it is | An emulsifier built from glycerin and a fatty acid, and one of the most common ways a Korean emulsion gets its texture. It is structural rather than active: no emulsifier, no lotion, just an oily layer floating on water. It also happens to feel softening on skin, which is a useful bonus. | Coconut-derived, fractionated, and nothing like coconut oil in behaviour. It is one of the most-used emollients in cosmetics because it is light, spreads beautifully and stays fresh for years. If a Korean cleansing oil or ampoule feels silky rather than greasy, this ester is often the quiet reason. |
