Glycerol formal

Glycerol formal (CAS 4740-78-7), also known as 1,3-Dioxan-5-ol, is a cyclic acetal solvent derived from glycerol that combines low volatility with strong solvency across polar and non-polar systems.

It functions as a solvent, humectant, and plasticizer in formulations where conventional glycols or standard solvents fall short on performance or regulatory fit. In coatings and adhesives, it improves resin compatibility.

This versatile chemical enhances film formation while reducing the need for more aggressive solvents. Personal care formulators use it as a humectant and carrier in skin and hair products for better results.

Its glycerol origin supports mild, skin-compatible positioning in various cosmetic applications. In industrial and household cleaning concentrates, it acts as a co-solvent that boosts active ingredient solubility.

This material ensures stability without compromising the integrity of the final formulation. Polymer and elastomer compounders incorporate it as a plasticizer to improve flexibility and processability in finished materials.

Glycerol formal is supplied as a clear liquid, typically at high purity levels suited for both industrial and cosmetic-grade applications. Technical and cosmetic grades are the most commonly available options.

Specifications vary by supplier based on purity, water content, and residual acetal profile. Packaging ranges from drums to IBC containers depending on order volume and specific logistical requirements for the client.
