Shell PANOLIN Biodegradable Products for Marine Applications
“Biodegradable lubricant” refers to products that can degrade more than 60% within 28 days according to the OECD 301B test. However, an “Environmentally Acceptable Lubricant (EAL)” represents more than just high biodegradability: it also includes low ecotoxicity, non-bioaccumulation, and compliance with technical performance requirements such as filterability, water separation, rust/corrosion protection, and resistance to washout. Therefore, the Shell PANOLIN series offers next-generation environmentally responsible solutions that combine sustainability with long-lasting performance.
'Biodegradable' and 'Environmentally Acceptable' Lubricants – What is the difference?
An “environmentally acceptable lubricant” is not only highly biodegradable, but also has low toxicity to plants and animals in the environment, does not bioaccumulate, and still meets minimum technical performance requirements.
What does “environmentally acceptable” mean?
The term refers to Shell PANOLIN EAL products, which are highly biodegradable, do not accumulate in the environment, and have low toxicity to plants and animals. These claims are supported by independent laboratory tests conducted in accordance with international standards such as ISO 17025.
How is biodegradability measured?
Biodegradability is measured using internationally recognized test methods. Shell uses the OECD 301B CO₂ Evolution Test, which is also recognized by the EU Ecolabel and other certification bodies.
What is the pass level for “readily biodegradable”?
In the OECD 301B test, a product is classified as “readily biodegradable” if it achieves more than 60% biodegradation within 28 days.
What is meant by low ecotoxicity?
Ecotoxicity refers to the potential harmful effect of a substance on the environment. It is assessed through short-term toxicity tests on organisms representing different levels of the food chain. Shell PANOLIN products are evaluated to ensure low toxicity in aquatic environments.
What does the EU Ecolabel for lubricants mean?
The EU Ecolabel confirms that products demonstrate reduced environmental impact throughout their life cycle. It considers biodegradability, aquatic toxicity, use of renewable raw materials, and restrictions on hazardous substances. Hydraulic fluids must also meet performance standards defined in ISO 15380.
How do environmentally acceptable lubricants differ from mineral oil hydraulic fluids?
The main difference lies in their base formulation. Shell PANOLIN (EAL) products are made from biodegradable synthetic esters and ashless additives with proven low ecotoxicity. Both product types are designed to deliver high hydraulic performance.
Do environmentally acceptable lubricants have performance issues or shorter service life?
No. This is a misconception based on older first-generation vegetable oil products. Shell PANOLIN uses modern synthetic ester technology, offering high oxidation stability and excellent performance under high operating temperatures.
