Description

Isopropyl alcohol (CAS 67-63-0), commonly known as IPA, is a fast-evaporating solvent used across cleaning, pharmaceutical, and personal care manufacturing. It dissolves a broad range of oils, resins, and active ingredients without leaving residue. This is a critical factor for processes where surface cleanliness or formulation clarity is required. In electronics manufacturing, IPA removes flux residues, fingerprints, and particulate contamination from PCBs and precision components.

It performs these tasks without damaging sensitive substrates. Pharmaceutical and healthcare manufacturers rely on it as a disinfectant and process solvent in tablet coatings, topical formulations, and cleanroom surface sanitation. In personal care, IPA functions as a solvent and preservative in antiperspirants, hand sanitizers, and skin toners. Its rapid evaporation supports consumer-acceptable dry-down in these various cosmetic applications.

Printing and packaging operations use it as a fountain solution additive and ink solvent to control viscosity and improve plate wetting. IPA is supplied as a liquid in concentrations typically ranging from 70% to 99%+ anhydrous grades. Standard specifications include USP, BP, and Ph.Eur. for pharmaceutical and cosmetic applications. It is also available in technical grade for industrial cleaning and general solvent use.

Bulk supply is available in drums, IBCs, and ISO tank quantities to meet large-scale industrial requirements. Our logistics network ensures consistent delivery of high-purity solvents for your manufacturing needs.
