Independent R&D for the food, beverage, dairy, pharma and personal-care industries — every raw material drawn from the NSF HX-1 whitelist, formulated specifically for the temperature, water-load and contamination realities of an Indian food-processing plant, and delivered with the documentation and registration support needed for a clean FSSAI audit.
NSF H1 is a registration administered by NSF International (Ann Arbor, USA) for lubricants used in food, beverage and pharmaceutical processing equipment where incidental contact with the product is possible. The technical basis is the US Code of Federal Regulations Title 21, Part 178.3570 — which lists the substances permitted for use in lubricants with incidental food contact and the maximum migration limit of 10 parts per million (10 mg/kg) of finished food.
In practical terms: every raw material in an H1 lubricant must appear on the NSF HX-1 whitelist (NSF's own audited listing of substances that comply with 21 CFR 178.3570). Conventional lubricant chemistry such as ZDDP anti-wear, sulphurised olefins, chlorinated paraffins and most calcium and magnesium detergents do not appear on HX-1 — which is why an H1 grease cannot simply be a conventional grease with the label changed. It is a fundamentally different formulation.
NSF maintains four food-contact-related lubricant categories. Choosing the right one defines the formulation chemistry, the raw-material restrictions, and the price-point of the finished product. Most enquiries we receive should be H1 — but a meaningful minority should actually be H2 or 3H, and the cost difference is significant.
| Component | Chemistry / Grade | Treat Rate | Function |
|---|---|---|---|
| Base oil | USP technical white oil, KV40 = 100 cSt | 80 – 84% | Primary fluid phase; carries the additive system; lubricates the contact |
| Aluminium-complex thickener | In-situ from stearic + benzoic acid + aluminium isopropoxide | 10 – 14% | Soap matrix that holds the oil; gives NLGI 2 penetration of 265 – 295 dmm |
| Antioxidant package | Aryl-amine + hindered phenol (HX-1 listed) | 0.5 – 1.0% | Oxidation resistance; extends service life at 80 to 120°C continuous |
| Rust & corrosion inhibitor | Sorbitan monooleate + amine sulfonate (HX-1) | 0.5 – 1.0% | Protects steel bearings against acid water spray-off in washdown environments |
| Anti-wear | Ashless amine phosphate (HX-1, no ZDDP) | 0.5 – 1.5% | Wear protection at boundary contact — replaces the role ZDDP plays in conventional grease |
| Metal deactivator | Tolyl-triazole derivative (HX-1) | 0.05 – 0.15% | Passivates copper, brass and bronze components against trace acidity |
| Solid lubricant (optional) | Food-grade PTFE 1 – 5 µm | 1 – 5% | Boundary-film stability at elevated temperatures; used in oven-chain variants |
| Pigment (optional) | Titanium dioxide (food-grade) | 0.1 – 0.3% | White appearance — preferred for visual identification in food plants |
A polyurea variant uses the same overall structure with the aluminium-complex replaced by 8 to 12% di- or tetra-urea thickener prepared in-situ. The polyurea grade trades a slightly higher raw-material cost for a 30 to 50°C dropping-point gain — preferred wherever oven-chain or high-temperature bearing duty is the application.
NSF H1 is a product registration — it confirms the formula uses HX-1 listed raw materials only. ISO 21469 is a facility-level certification that audits the hygienic design of the lubricant manufacturing operation: dedicated production lines or thorough segregation, clean-room blending, food-contact-grade packaging, contamination risk assessments, batch traceability, and an annual third-party audit. ISO 21469 is mandatory for the largest food-processing customers in Europe and increasingly requested in India by FMCG audit programmes.
Our work covers H1 product formulation and registration. For ISO 21469 we work alongside the client's manufacturing partner on the facility readiness — specifying the dedicated H1 blender, the cleaning protocol, the segregation drawing, the packaging procedure and the batch-record format. The combination of NSF H1 (product) + ISO 21469 (plant) is the gold-standard answer to an FSSAI or BRC food-safety audit asking about lubricant risk in the food zone.
India's food-processing sector has matured significantly. Ten years ago, food-grade lubricant demand in India was small, niche and largely export-driven. Today, every major FMCG plant in India is audited annually against international food-safety codes — FSSAI of course, but also BRC (British Retail Consortium) for UK / Europe exports, SQF (Safe Quality Food) for North-American exports, IFS Food, FSSC 22000 and the FMCG's own corporate audit programme. Every one of these audits asks the same question: what lubricant is used in the food zone, and what is its NSF H1 status?
The customer base now insisting on NSF H1 in India includes Mondelez (Cadbury), Britannia, ITC Foods, Nestlé India, Hindustan Unilever, Amul, Mother Dairy, Hatsun Agro, Parle, Haldiram's, Bikaji, Vadilal, Patanjali, Dabur, Pepsi-Frito Lay, Coca-Cola and the major pharmaceutical formulation houses (Sun Pharma, Cipla, Dr Reddy's, Lupin). Demand is also strong from the personal-care segment (cosmetics, soaps, toothpaste) where the same 21 CFR 178.3570 framework applies through the FDA's parallel personal-care provisions. The combined Indian addressable market for NSF H1 grease has grown by roughly 4x over the last decade and continues to expand at double-digit CAGR.
No — the two are complementary and address different layers of food-safety risk. NSF H1 is a product-level registration confirming the formulation uses only HX-1 listed raw materials. ISO 21469 is a facility-level certification covering the hygienic design of the manufacturing operation, segregation, packaging, batch traceability and risk assessment.
The two together give the highest assurance level and are typically requested by global FMCG corporate audit teams. Smaller Indian food customers will often accept NSF H1 alone; multinationals frequently insist on both.
Yes — provided the chosen H1 grease has the right dropping point and oxidation stability for the chain temperature. For oven chains running above 200°C continuously (bread, biscuit and tunnel-oven applications), a PTFE-thickened H1 grease or a polymer-fortified aluminium-complex H1 grease is preferred over a standard aluminium-complex.
We routinely formulate H1 oven-chain greases with dropping points above 260°C and proven service at 220 to 240°C continuous chain-temperature. The cost-per-kg is higher than a standard food-grade NLGI 2 grease, but the cost-per-service-hour is far lower because of the dramatically reduced re-greasing interval.
FSSAI itself does not maintain a parallel lubricant registry or testing programme — FSSAI is the food-product regulator, not the lubricant regulator. The FSSAI compliance angle for an Indian food-processing customer is the assurance that any incidental-contact lubricant used in the plant is NSF H1 registered.
We provide the supporting documentation that a food-processing FSSAI auditor or an internal HACCP audit will ask for: the NSF H1 registration number, the NSF White-Book listing, the H1-compliant TDS, the GHS-aligned SDS and the change-control history of the formulation.
