Answer
Usage Rate for Propanediol (1,3-Propanediol)
Based on the product information for Propanediol (1,3-Propanediol) (e.q. Zemea), the recommended usage rate for cosmetic formulations such as serums, lotions, or creams is 1-20%.
While 1,3-Propanediol can technically be used at higher concentrations, even up to 100% as a pure solvent, the 1-20% range is the typical and recommended concentration when used in cosmetic products for its functions as a humectant, solvent, or preservative booster.
