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.
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.

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.
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.
