- It’s Time for a Better Glycol
- Good For People - Safe + pure. Brontide contains no heavy metals at detectable levels and has been shown in clinical studies to be nonirritating at levels of up to 40% in formulation.
- Good For Our Planet - Brontide is a natural butylene glycol. Made from renewable, non-GMO plant sugars, Brontide reduces global warming potential by over 50% compared to petroleum-based butylene glycol.
- Good For Formulators - Brontide integrates into current formulations without sacrificing quality or needing reformulation.
- Product Highlights
- Brontide is safe for skin
- Brontide was tested at levels of 10%, 20%, 40%
- Clinical Test (HRIPT) showed : no fatigue, no skin irritation, no sensitization.
- Brontide is shown to enhance clarity and expression of aroma ingredients - lower formulation costs increased performance.
- Brontide was noted to have a better skin feel after alcohol portion was evaporated - Combined with skin safe benefits, Brontide is great for skincare applications.
- Brontide has a similar solubility profile to DPG in formulation - Brontide can play a role as co-diluent, easy to increase natural content and lowered carbon footprint.

Technical Details & Test Data
- The Innovative Process
Brontide is made in Europe from an innovative fermentation process which converts non-GMO plant sugars into an ultra high purity butylene glycol, eliminating the need to use crude oil as a feedstock.
- Good for our Planet
Genomatica completed a third-party, peer-reviewed life cycle assessment (LCA) based on ISO 14040:2006 that substantiates and measures Brontide natural butylene glycol’s sustainability story.
- 50% reduction in greenhouse gasses.
- Life cycle assessment peer - reviewed

Brontide natural butylene glycol can provide a more predictable outcome from formulation to compounding when adding new materials to fragrance.
Solubility of 105 common fragrance ingredients diluted in Brontide was visually inspected, given rating of (1) poor, (2) moderate, (3) good, (4) excellent. Organoleptic performance was given a rating of (1) poor to (10) excellent.
- Brontide Solubility Performance 96 Fragrance Ingredients
- Brontide performs best where ingredients have lower molecular weight and lower logP values.
- Stronger solubility performance with more polar synthetic category of ingredients, inconsistent performance in less polar natural category.
- Results exclude ingredients without clear MW and logP, primarily non-polar, oil-based ingredients.
- Carbon Footprint of Comparable Glycols
Compared to its petroleum-based counterpart, Brontide results in the largest reduction in greenhouse gas emissions and the lowest carbon footprint overall.
- PG->PDO GHG reduction: 42%
- BG->Brontide GHG reduction: 51%
