Petrochemical
Acetone, MEK, NMP, DMF, toluene, xylene, paraffins: most industrial solvents are still made from oil.
Replace the solvent.
Keep the performance.
Go carbon neutral.
Italy's leading developer of bio-based solvents, since 2006.
Proprietary blends that mimic the petrochemical solvent you use today, so your process can stay as it is.
Same process. Different carbon.
Each ASTROBIO™ grade blends esters, alcohols, glycols and amides from renewable resources to match the physicochemical properties of one petrochemical solvent. When your application needs it, we adapt the blend.
Some grades include a variable share of fossil co-solvents.
Bio-based
Their ASTROBIO™ twins: blends built to do the same job, from renewable carbon.
Twenty-four petrochemical solvents already have their twin.
Each green code is the ASTROBIO™ grade designed to replace the solvent beside it. Not on the list?

Bio-based is the reason to try.
Performance is the reason to stay.
20-30%
more efficient than the related fossil solvents at reducing viscosity.
Strong solvency power
For many resins, polymer grades and soils, with a high loading capacity: less solvent for the same result.
Lower evaporation losses
In cleaning applications they stay on the job longer.
Easy to distill and recycle
Recovering spent solvent is simple and inexpensive.
Fewer surface defects
In formulations they help avoid craters, fisheyes and orange peel.
Follow the carbon.
Our raw materials come from renewable resources: corn, wheat, sugar beet and wastes of the paper and wood industry.
1
Photosynthesis
Plants take CO₂ from the air and build it into starches, sugars and cellulose.
2
Conversion
Renewable raw materials become esters and derivatives of natural acids, bio-based alcohols, glycols and amides.
3
Blending
We blend them in the right amounts to mimic the solvent you need to replace.
4
Back to nature
Every component is readily or inherently biodegradable according to OECD guidelines.
1 g out, 1 g in.
For every gram of CO₂ a biosolvent releases, one gram was removed from the atmosphere by photosynthesis. This balance is what carbon neutral means.

What you won't find in an Astrobio blend:
Irritant, nothing more
Our replacements for NMP and DMF are labelled just as irritant.
Non-flammable options
Non-flammable replacements are available for flammable solvents.
Back to nature in under 67 days
All components are readily or inherently biodegradable according to OECD guidelines, with complete mineralization in less than 67 days.
