Phenoxyethanol, Ethylhexylglycerin

This synergistic preservative blend combines phenoxyethanol, a glycol ether with broad-spectrum antimicrobial activity, with ethylhexylglycerin, a multifunctional ingredient derived from glycerin that enhances preservative efficacy while providing skin conditioning benefits. The combination allows formulators to use lower concentrations of phenoxyethanol (typically 0.5-1.0% instead of 1.0% alone) while maintaining effective preservation, making it a popular choice for natural and sensitive skin formulations. Ethylhexylglycerin also acts as a deodorizing agent and improves the skin feel of the final product, addressing common concerns about phenoxyethanol's sometimes drying effect when used at higher concentrations.
