Methylheptyl Laurate

Methylheptyl Laurate is a lightweight ester of lauric acid (usually coconut-derived) and methylheptanol. It works as an emollient - it softens skin, spreads easily, and leaves a silky, non-greasy finish.

Formulators often use it as a plant-based alternative to silicones and heavier esters like isopropyl myristate. You'll spot it most often in sunscreens, primers, and lightweight moisturizers where a clean, dry-feeling texture matters. It's also good at dispersing mineral UV filters and pigments, which is why it turns up in a lot of makeup.

Low irritation risk and generally fine for most skin types. One heads-up: it's an ester of lauric acid (C12), which falls in the range of fatty acids that Malassezia yeast feeds on - so it isn't fungal acne-safe.
