An Indian Biodegradable Grease Patent: Ester Base, Lithium Complex, OECD 301B
IN 202411012294 (filed Feb 2024) cooks a lithium-complex soap in a synthetic ester claimed at 70–90 wt% with OECD 301B ready biodegradability >60%. It is a process patent, not a VGP ticket. Ester + LiX is the easy EAL start; oxidation and…
Direct answer
IN 202411012294 (filed Feb 2024) cooks a lithium-complex soap in a synthetic ester claimed at 70–90 wt% with OECD 301B ready biodegradability >60%. It is a process patent, not a VGP ticket. Ester + LiX is the easy EAL start; oxidation and hydrolytic stability are still the gates.
- IN 202411012294 (filed Feb 2024) cooks a lithium-complex soap in a synthetic ester claimed at 70–90 wt% with OECD 301B ready biodegradability >60%.
- IN 202411012294 is an Indian biodegradable lithium-complex ester grease filing. Cite it as domestic prior art. Biodegradability claims still need the method (OECD, ISO 15380 family) and the base-oil story, not the word ‘bio’ on a tin.
- Name the test method on any number that reaches a TDS.
- Patents and papers are prior art, not a product Lubechem sells.
- Written for Indian exporters building an EAL SKU.

Lubechem will not invent a client list or a certificate. If the next step is a trial, send the duty brief. If the next step is legal clearance of a filing, that sits with a patent attorney.

How to use this filing as prior art — not as a recipe
| Question | What to extract | What not to do |
|---|---|---|
| What problem is claimed? | An Indian Biodegradable Grease Patent: Ester Base, Lithium Complex, OECD 301B | Do not treat the abstract as a proven plant SOP |
| Thickener / additive families named | biodegradable grease formulation India | Do not copy claim language into a TDS |
| Examples vs claims | Worked oils, solids, treat ranges in examples | Examples are not a licence |
| Design-around | Unclaimed process windows, other thickeners | FTO is legal advice; Lubechem does not issue it |
| Citation in this article | IN 202411012294, pub. 37/2025, filed 21 Feb 2024 | Cite, do not reproduce claims |
People-first note: this is dated editorial for decision-making. It is not a scaled rewrite of the manufacturing pages, and it is not legal or certification advice.
Questions plants actually ask
Is biodegradable grease formulation India a drop-in for whatever we run today?
Almost never. Thickener family, base-oil viscosity, NLGI grade and additive response all have to be matched to the duty. A purge plan comes before a plant-wide switch. Compatibility charts are screens, not guarantees.
Can we put biodegradable grease formulation India on the TDS because a patent or paper mentioned it?
No. Patents are prior art. Papers are evidence under stated conditions. A TDS line has to be backed by a method you actually ran, on oil you actually stock, at a treat you can buy twice.
Who owns the formula if Lubechem develops it?
Ownership is the contract. The practice is independent formulation with IP transfer as scoped — not a branded additive package you can never leave. Ask for the assignment language before the first kettle.
What should Indian exporters building an EAL SKU send in the first brief?
Duty (load, speed, water, temperature, relube), the current TDS and fail mode, target specs (IS / ASTM / OEM), and whether the product is sold, used in-house, or exported. Photographs of the failed component help more than adjectives.
