Glycerol ACS (also called glycerin) is a clear, colorless, viscous liquid used as a humectant, solvent, and sweetener in pharmaceuticals, cosmetics, and food industries. It’s also a key ingredient in inks, tobacco, and personal care products due to its hygroscopic and non-toxic properties. This reagent-grade glycerol meets ACS specifications with a CAS number of 56-81-5, molecular formula C3H8O3, and molecular weight of 92.05. It is stored at ambient conditions, requires no signal word, and is fully documented for compliance. Molekula supplies Glycerol ACS from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
