Humectant

Vegetable Glycerin USP/EP

CAS 56-81-5

Pharmaceutical-grade glycerol from vegetable feedstocks. Identity and limits aligned to USP and European Pharmacopoeia monographs with batch CoA documentation.

Plant-derived glycerol with batch-level identity traced to compendia limits. Chloride and sulfate testing is harmonized so dual USP / EP wording stays honest on specs — EU and US formulation teams read the same CoA semantics.

Specifications

Representative release criteria; lot-specific limits on CoA prevail.
