In response to the European Commission’s mandates M/430 and M/491, the European Committee for Standardization (CEN) developed the following standards:
European standard EN 16807 sets the requirements and criteria for bio-based lubricants. It specifies the term “bio-lubricant” and briefly describes relevant test method needs with respect to its characterization.
EU Ecolabel for Lubricants
The European Commission’s EU Ecolabel has specified a minimum bio-based carbon content of 25% for lubricants using the terms “bio-based” or “bio-lubricant”. The bio-based carbon content will be measured according to EN 16807, ASTM D6866, CEN/TS 16137 (SPEC 91236), EN 16640 or EN 16785-1. This criteria for lubricants remains valid until December 31, 2024.
The EU Ecolabel is a voluntary scheme valid throughout the European Union, Norway, Iceland and Liechtenstein.

The CEN first developed CEN/TS 16766 for bio-based solvents in 2015, which was eventually superseded by European standard EN 16766:2017. The standard sets requirements for bio-based solvents in terms of their bio-based content, their technical properties and test methods.
European standard EN 16766 also:
– specifies solvent classes based on the bio-based carbon content, which will be determined as described under standards EN 16640 or EN 16785-1; and
– sets requirements on information to be provided regarding the sustainability aspects of bio-based solvents.
For details, please purchase a copy of EN 16766:2017 – Bio-based solvents – Requirements and test methods.
Technical specification CEN/TS 17035:2017 sets requirements for bio-based surfactants in terms of properties, limits, application classes and test methods. It also recommends sub-sampling procedures for various forms of surfactants (e.g. dry solid, paste, gel, liquids).
A European standard based on the technical specification for bio-surfactants is currently under approval. Once published, the standard will supersede CEN/TS 17035.
What are Bio-based Surfactants?
CEN/TS 17035 describes a bio-based surfactant as a surfactant that is wholly or partly derived from biomass produced either by chemical or biotechnological processing.
The technical specification includes a classification system based on the bio-based carbon content of the surfactant to clarify naming used in the industry. The bio-based carbon content measurements will be done according to standards EN 16640, EN 16785-1 or EN 16785-2.
CEN/TS 17035 allows inclusion of the classification and bio-based carbon content percentage on product labels.
More details can be found in prEN 17035 – Surface Active Agents – Bio-based surfactants – Requirements and test methods (available online for a fee).
