Citrullus Lanatus (Watermelon) Seed Oil

CIT

9/10

Concern level

High concern

A lightweight plant-derived fixed oil expressed from watermelon seeds, composed mainly of triglycerides rich in linoleic and oleic fatty acids. In cosmetics it functions primarily as an emollient and skin-conditioning oil, helping reduce transepidermal water loss and improve softness without the heavy feel of many richer oils. CIR lists it as safe in the present practices of use and concentration, and supplier SDS documents describe it as non-irritating in typical cosmetic use.

Risks & Warnings

As with any oxidizable unsaturated oil, aged or poorly stored material may become rancid and more irritating. Avoid if you have a known allergy to melon or related seed oils.
