What it is
Cyclohexylglycerin is a synthetic glyceryl ether structurally related to ethylhexylglycerin and similar multifunctional glycols. It is used mainly to enhance the antimicrobial efficacy of a formula, allowing reduced reliance on conventional preservatives, and it also contributes mild skin-conditioning and humectant effects. It is typically added at low concentrations as part of a broader preservation system.
Safety & warnings
It is generally well tolerated at the low use levels typical for preservative-boosting ingredients and is not a recognized fragrance allergen or notably comedogenic material. As with related glyceryl ethers, sensitivity is uncommon but possible in reactive skin.
Origin & sourcing
Synthetic; produced industrially as a glyceryl ether.

Is cyclohexylglycerin a preservative?
It is best described as a preservative booster and conditioning agent rather than a standalone preservative; it works alongside other preservatives in the formula.
