What is Cyclohexanol?
Cyclohexanol (CAS 108-93-0), also known commercially as Hexalin or Hydralin, is a cyclic alcohol used primarily as a solvent and chemical intermediate in pharmaceutical and personal care manufacturing.
Where is Cyclohexanol used?
- Pharmaceutical manufacturing: process solvent for synthesizing active pharmaceutical ingredients
- Personal care: humectant in skin-conditioning creams and lotions, supporting moisture retention
- Fragrance compounding: carrier solvent for aromatic compounds
- Industrial cleaning and surface treatment: cuts through greases and resins where water-miscible solvents underperform
- It dissolves active ingredients and excipients that resist conventional solvents.
Good to know: Buyers sourcing for pharmaceutical or cosmetic use should confirm compliance with pharmacopeial standards such as USP, Ph. Eur., BP, or EP prior to procurement.
Commercial specifications
- Purity typically 99% or higher for regulated applications
- Clear liquid in drum and IBC quantities; bulk tanker options for larger volumes
