Ethylhexylglycerin is a kind of alkyl glyceryl ether. A colorless liquid, this synthetic compound is derived from vegetable glycerin (which often comes from palm or coconut oil).

Ethylhexylglycerin is a synthetic skin-softening agent. Ethylhexylglycerin can also be used as a preservative and carrier/suspending agent that boosts the efficacy of other preservatives such as phenoxyethanol. It has been shown to have mild humectant properties leading to improved skin hydration without a sticky feel.
