Lubricant & Grease Formulation
for Pharma & Cleanrooms

Independent R&D for the lubricant basket a regulated pharmaceutical plant actually consumes — USP and BP grade white mineral oil in light, medium and heavy viscosity; medical-grade polydimethylsiloxane silicone fluid and silicone grease; tablet-press die lubricant for direct compression; cleanroom-friendly NSF H1 / ISO 10993 grease for tablet-coating, granulation, capsule-filling and packaging machinery; dust-free synthetic lubricants for dry-zone equipment; and the support-utility oils (compressor, chiller, hydraulic) where contamination must not reach the product. Built around US FDA 21 CFR, USP and BP monograph requirements, EU EMA standards, WHO GMP, and the technical specifications used by Sun Pharma, Cipla, Dr Reddy’s, Lupin, Cadila, Aurobindo, Biocon and Serum Institute.

What This Industry Specifically Demands

The Chemistry Constraints
Unique to Pharma

Pharmacopoeia-grade base oil is the starting point. Pharma plants do not use Group I or II mineral base oil. The base is USP-grade white mineral oil meeting the USP <<Liquid Paraffin>> monograph — or BP-grade meeting BP Paraffinum Liquidum — or polydimethylsiloxane silicone meeting FDA 21 CFR 175.300 — or food-grade PAO. The choice of monograph compliance is dictated by which markets the finished pharmaceutical will be exported to: USP for US ANDA, BP for UK/EU, JP for Japan PMDA. We carry parallel USP/BP-compliant formulations for clients with global supply.

Cross-contamination risk drives separation. A pharma plant blending a steroid line and a non-steroid line keeps the lubrication for each line strictly separate, with colour-coded grease cartridges and dedicated grease guns. The lubricant supplier must provide product in tamper-evident sealed packaging with clear batch identification — not bulk drums. We design our pharma supply to come in NSF-grade cartridges (400g standard) with QR-coded batch traceability that integrates with the customer’s GMP batch record.

ISO 10993 is the new entry standard for medical-device-adjacent applications. Lubricant used in syringe siliconisation, catheter assembly, implant component machining and the medical-device side of pharma operations increasingly requires cytotoxicity data (ISO 10993-5), sensitisation data (ISO 10993-10) and irritation data (ISO 10993-23). We commission these biological evaluations through accredited labs as part of our regulatory documentation.

Dust pickup must be designed against. A granulation room or tablet compression room has fine powder airborne. Lubricant on the exposed surface of a tablet press, a fluid-bed dryer, a granulator agitator must not act as a fly-paper for that powder — the resulting dust-mass causes powder cross-contamination between batches. The formulator designs with low-surface-energy synthetic ester base, ash-free additives, and (where consistency permits) a slightly drier feel that does not actively pick up loose powder.

Case Study

Tablet-Press Die Lubricant
for a High-Speed Coated Tablet Line

Completed Engagement · Tablet Press Lubrication
Hyderabad-Based Generic Pharma Major — PDMS Die Lubricant Replacing Imported Brand
A Hyderabad-based generic pharmaceutical company operating high-speed Korsch XL-400 tablet presses on a coated antibiotic product was importing PDMS die lubricant aerosol from a US supplier at roughly Rs 1,400 per 400-ml can. Annual consumption across three formulation blocks was around 24,000 cans. The product was used to lubricate die walls during compression to avoid sticking of the coated tablet, and the imported supplier had been the validated vendor for over a decade.
We reformulated using Indian-sourced medical-grade PDMS at 1000 cSt with a USP-grade propellant blend (DME and isobutane). The finished aerosol was bench-tested for spray pattern, valve performance, residual solvent and compatibility with the antibiotic formulation. ISO 10993-5 cytotoxicity testing was commissioned through a Bengaluru NABL lab. The product was qualified through the client’s standard vendor-change procedure (formulation comparability, batch records, full QC release) over a 5-month validation cycle. Delivered cost was Rs 520 per can — a 63% reduction.

Questions & Answers

Frequently Asked About
Pharma Lubricant R&D

What grade of white mineral oil is used in pharma?

USP-grade and BP-grade white mineral oil are the dominant choices, with viscosity from light (15 cSt at 40C) to heavy (70 cSt at 40C). USP grade meets the United States Pharmacopeia liquid paraffin monograph; BP grade meets the British Pharmacopoeia Paraffinum Liquidum monograph. Both have PAH below 5 mg/kg.

White oil is used as an excipient in topical formulations and capsule processing, as a tablet processing aid, and as the base oil for pharma-machinery lubricant. The exact USP / BP / JP / IP grade is selected based on the export markets for the finished pharmaceutical.

Why is silicone fluid used in tablet press dies?
Polydimethylsiloxane silicone fluid is chemically inert, FDA 21 CFR 175.300 compliant, and does not react with API or excipient. It provides a non-stick boundary layer between tablet powder and die wall, allowing clean ejection of compressed tablets — particularly for sticky formulations (coated tablets, effervescent, sustained-release matrices) where dry magnesium stearate alone is insufficient. The silicone film is sub-microscopic, does not appear in the finished tablet, and does not affect dissolution.
What is ISO 10993 and does my lubricant need it?

ISO 10993 is the international standard series for biological evaluation of medical devices and the materials that contact them. ISO 10993-5 covers cytotoxicity, 10993-10 covers sensitisation, and 10993-23 covers irritation. Together these are the entry-level biological evaluation requirements.

Lubricants used in medical-device manufacturing — syringe siliconisation, catheter assembly, implant component machining — increasingly require ISO 10993-5 and 10993-10 data as part of supplier qualification. Pure pharma-machinery lubricant (above the product line) typically does not need ISO 10993, but the medical-device side of pharma operations does.

Can NSF H1 grease be used in pharma plants?
Yes — NSF H1 is the practical default for pharma machinery above the product line. Aluminium-complex and polyurea greases on USP white-oil base are the dominant choices. They are NSF H1 registered, conform to FDA 21 CFR 178.3570, and are appropriate for the bearings, gear cases and packaging machinery typical of a pharma plant. Some sterile and aseptic environments additionally require WHO GMP / cGMP-aligned documentation, which we provide.
Do you formulate dust-free lubricant for dry granulation areas?
Yes. The challenge is avoiding powder pickup by the lubricant film — airborne API and excipient powder must not adhere to the exposed surface of the machinery lubricant. We design with non-tacky synthetic ester base and ash-free additive systems that minimise particle attraction. For high-potency API granulation, the lubrication points are also engineered for sealed cartridge supply to eliminate any exposed grease surface.
Can you supply lubricant for Sun Pharma, Cipla, Dr Reddy approved vendor lists?
We formulate to the technical specifications required by Sun Pharma, Cipla, Dr Reddy’s, Lupin, Cadila, Aurobindo, Biocon and Serum Institute. Direct commercial supply requires the manufacturer to qualify on the relevant approved vendor list (AVL) — a process that typically involves site audit, document review and a qualification batch. We support that qualification documentation but the AVL relationship is between the manufacturer and the pharma company.
How is pharma lubricant packaged for cleanroom use?
Pharma lubricant supply is in sealed cartridges (400g standard for grease, 1L sealed bottles for oil) with tamper-evident closures and lot-coded labels that integrate with the customer’s batch records. Aerosols are supplied in pharma-grade cans with no contamination from prior-use packaging. Bulk supply (drums) is rare and limited to non-cleanroom support utilities.
