Brontide butylene glycol

We’re conscious of the environmental impact we make, from the farmland growing our sugar feedstock to the water used in our purification process.

We carried out a life cycle assessment (ISO:14040:2006) to quantify our environmental impact compared to petroleum-based butylene glycol that was peer-reviewed by an independent panel.

The impacts of Brontide natural butylene glycol are vastly lower.
