Propanediol is a naturally derived, skin-friendly glycol used to enhance the performance of cosmetic formulations. It serves as a gentle humectant, improves ingredient solubility, and can boost the efficacy of preservatives. Derived from corn sugar fermentation, it is an excellent alternative to petroleum-based glycols like propylene glycol.
Propanediol is a versatile ingredient suitable for nearly every type of cosmetic formulation. It hydrates the skin, helps solubilize active ingredients, and contributes to a pleasant skin feel. It is ideal for replacing traditional glycols with a naturally sourced, non-irritating alternative that aligns with clean beauty principles.
