Isopropyl alcohol, commonly called IPA or 2-propanol, is a high-demand solvent used across pharmaceuticals, electronics, cosmetics, printing, coatings, laboratories, cleaning products, and surface sanitation. For Indian manufacturers, the key sourcing question is not only price or availability; it is whether the grade, purity, documentation, and packing match the application.
Supreme Petro Chemicals supplies IPA from Chennai to industrial buyers across South India. This guide explains how to specify IPA correctly and what to verify before placing a bulk order.
What Is IPA?
IPA has CAS number 67-63-0. It is a clear, volatile, flammable alcohol solvent that evaporates quickly and mixes with water and many organic solvents. Its balance of solvency and evaporation speed makes it useful for both manufacturing and cleaning applications.
Common IPA Grades
IPA 99%
IPA 99% is used where low water content is important, such as electronics cleaning, printing, coatings, pharmaceutical cleaning, and solvent blending. Buyers should request a CoA that confirms assay and water content.
IPA 70%
IPA 70% is commonly used for surface sanitation because water improves wetting and contact time. If buying IPA 70%, confirm whether it is ready-to-use material or diluted from 99% grade at the buyer's site.
IP, BP, USP, and Pharma Grades
Pharmaceutical buyers should specify the required pharmacopoeial standard: IP, BP, USP, or another approved standard. The term "pharma grade" alone is not enough for GMP procurement. Batch-specific CoA and manufacturer-origin documentation may be required.
Applications Across Indian Industry
- Pharmaceuticals: Equipment cleaning, topical formulations, extraction, and excipient use where the correct grade is approved.
- Electronics: Circuit board cleaning, surface preparation, and removal of flux residues.
- Printing and inks: Solvent and viscosity adjustment in selected ink systems.
- Cosmetics and personal care: Solvent and carrier in specific formulations.
- Laboratories: Cleaning, reagent preparation, and general solvent use.
- Industrial cleaning: Fast-evaporating cleaner for oils, residues, and light contaminants.
Packaging Options
IPA is commonly supplied in carboys, 200-litre drums, IBC tanks, or larger bulk arrangements depending on volume and destination. Packaging must be compatible with flammable solvent handling and storage rules at the buyer's site.
Documentation and Quality Checks
For industrial use, ask for MSDS/SDS and CoA. For pharmaceutical or audited use, confirm batch number, manufacturer name, country of origin, pharmacopoeial reference, assay, water content, acidity, non-volatile residue, and impurity profile as required by your quality team.
Storage and Safety
IPA is flammable. Store it in approved, ventilated areas away from heat, sparks, open flames, oxidisers, and incompatible materials. During transfer, follow earthing and bonding practices. Workers should use appropriate PPE and follow the SDS.
FAQ
What is the CAS number of IPA?
The CAS number of isopropyl alcohol is 67-63-0.
Can IPA 99% be diluted to IPA 70%?
Yes, but dilution should be controlled with suitable water quality, mixing procedure, and documentation where required by the application.
