What Ethylhexylglycerin does

Boosts other preservatives
Helps keep products fresh
Conditions skin, helping it feel smooth

Ethylhexylglycerin is made in a lab. Chemists join a glycerin-based building block with 2-ethylhexanol, an eight-carbon alcohol, to make a clear liquid that blends easily into water-based formulas.

Formulators use it mainly as a preservative helper. It has some antimicrobial action of its own (it slows microbe growth), but its real value is boosting other preservatives, which helps a product stay fresh over time. It feels light on skin and leaves little stickiness, so it fits well in moisturizers, cleansers, sunscreens, and serums.

Good for

Suits most skin types, and is often used in lightweight formulas like moisturizers, cleansers and serums.

Be careful if

Nothing in particular for most skin types.
