A Brand new opportunity in Butyl glycol replacement: Astrobio™ BC

Tabella dei Contenuti

Butyl glycol replacement? Now it’s possible!

We would like to highlight and updating ruling and labeling perspectives of a very widespread solvent, butyl glycol (CAS  111-76-2).

This solvent, with an estimated EU consumption of several hundred thousand MT per year, has a huge number of applications, as the following ones:

  • Butyl glycol solvent for paints and coatings,
  • Butyl glycol as cleaning for inks,
  • Butyl glycol based lacquers, varnishes and enamels formulation,
  • Butyl glycol varnish removers
  • Butyl glycol acrylic resins formulations,
  • asphalt release agents,
  • firefighting foams,
  • leather protectors,
  • liquid soaps,
  • cosmetics,
  • dry cleaning solutions,
  • herbicides,
  • silicone caulks,
  • oil spill dispersant,
  • formulation of fracturing fluids for oil drilling,
  • drilling stabilizers,
Global Butyl Glycol Market Snapshot
Butyl Glycol Market trends for the future

There is a written proposal of modification of  buthyl glycol’s harmonized classification, based on the revision of the most recent scientific literature regarding buthyl glycol toxicity. The document was issued by the German Federal Institute for Occupational Safety and Health (BauA), based in Dortmund, on 2017.

Here we would like to report and highlight the opinion written and adopted, the 14th September 2018, by the RAC (Risk Assessment Commission) regarding the matter.

In all likelihood, the RAC opinion will be officially adopted by the European Commission, upsetting the classification of butyl glycol and definitively identifying it as a dangerous substance, capable of causing acute toxic effects on humans

The following risk phrases will go to be mandatory for this solvent, starting from 2021 or 2022 (deadline still to be decided):

  • Acute Tox. 4, H302
  • Acute Tox. 3, H331
  • Skin Irrit. 2, H315
  • Eye Irrit. 2, H319

As a first consequence, this solvent will be included in ADR regulations too, due to the phrase H331.

As a second, heavy consequence, it will be labelled with the following pictogram:

GHS06 – Skull and cross-bones,
that will be followed by the statement: “Danger”

The following new ATE (Acute Toxicity Estimate) will be also introduced:

  • inhalation: ATE = 3 mg/L
  • oral: ATE = 1200 mg/kg bw
The old classificafication of butyl glycol required only the labelling with the “exclamation mark” pictogram followed by the statement “Warning”.

For all details about this matter, available to the public, let inform yourself by clicking on the following link (in English).


It is obvious that all companies, using this chemical, have to be aware as soon as possible of these future, but unavoidable, short-term and heavy, variations related to this solvent.

As a confirmation, we have already received, by our website, a great number of enquiries about possible replacements of it.

We are very glad to announce you that our ASTROBIO™ BC specialty, a bio-based solvent has been proven to be very efficient in replacing the above mentioned butyl glycol and, for this reason, is already distributed all around Europe.

Its MSDS shows just a GHS07 pictogram (Irritant).
