Our production sites in Europe are ISCC PLUS certified and use advanced process systems to guarantee high traceability and quality. ISCC PLUS (International Sustainability and Carbon Certification) is an internationally recognized, voluntary certification scheme that verifies the sustainability and traceability of bio-based and circular raw materials throughout the supply chain. It relies on a mass balance approach: the quantity of renewable or recycled feedstock entering the production process is tracked and attributed to the finished products, so that customers can rely on documented claims about the bio-based or circular content of the solvents they purchase. Certification is based on independent third-party audits covering the whole chain of custody, from raw material sourcing to delivery, which gives customers transparency and confidence in their sustainability reporting.

Lactate solvents provide high solvency power, low toxicity, and excellent compatibility with polymers, resins, and water-based coatings. They offer a versatile bio solution for fine chemicals, industrial cleaning systems, and sensitive pharmaceutical manufacturing.
Choosing a solvent means balancing technical performance, safety, regulatory compliance, and sustainability. On the environmental and safety side, low-VOC or VOC-free solvents are increasingly preferred as regulations tighten, and the GHS hazard classification and life-cycle carbon footprint should be checked, with a safer substitute considered whenever possible. Physical properties also matter: evaporation rate and vapor pressure (a balanced rate prevents defects such as blushing in coatings and inks), viscosity, density, surface tension, and flash and boiling points, which determine handling safety and recovery options. Hansen Solubility Parameters help estimate how well a solvent will dissolve a given solute or polymer, and bio-based or circular solvents can deliver strong performance with a significantly lower carbon footprint. A decision matrix is a practical way to weigh all these factors transparently, and our technical team can help you select the best solvent for your application.

neo range is a line of green solvents that combines industrial performance with sustainability. It rests on five criteria, and a solvent can meet one or several of them.
Z (Towards Zero carbon) covers solvents that cut CO₂ emissions by 45% to 100% compared with fossil-based alternatives. This is verified by LCA or PCF data covering scopes 1, 2 and 3.
B (Biobased) covers solvents made from natural, bio-sourced or mass-balanced plant-based ingredients.
C (Circular economy) covers solvents that reuse co-products, by-products or recycled materials instead of virgin raw materials.
S (Safer substitute) covers low-risk alternatives to hazardous chemicals, with no CMR substances and lower labeling requirements, without loss of performance.
D (Biodegradable) covers solvents that break down naturally, as shown by tests such as OECD 301. They suit sensitive applications like cosmetics, pharmaceuticals and food processing.
For example, neo Isopropanol is inherently low-carbon (Z). It is also available in a circular version (neo-ZC Isopropanol) and a renewable version (neo-ZB Isopropanol).
