Thioglycerol

Thioglycerol (CAS 96-27-5), also known as MTG, is a sulfur-containing diol used across pharmaceutical, cosmetic, and specialty chemical manufacturing. It functions primarily as a reducing agent and stabilizer. This chemical protects sensitive compounds from oxidative degradation during formulation and processing. In pharmaceutical manufacturing, it stabilizes active ingredients prone to oxidation, extending shelf life in injectable and topical formulations.

Personal care formulators incorporate it into hair treatment products, where its thiol group participates in breaking and reforming disulfide bonds to reshape hair structure. It also acts as a humectant in cosmetic preparations. This helps finished products retain moisture and maintain texture over time. In specialty chemical synthesis, MTG serves as a cross-linking agent and intermediate for producing thioether compounds used in polymer and resin systems.

Thioglycerol is supplied as a clear to pale yellow viscous liquid. Pharmaceutical-grade material is available to meet USP and BP specifications, while technical-grade material serves industrial synthesis applications. Packaging typically ranges from small laboratory quantities up to bulk drum supply for commercial-scale production. This ensures that manufacturers can source the exact volume required for their specific industrial or laboratory needs.
