Why Bio-Based Color Matters — Insights from Claessen Blue™ TÜV LCA Verification
TÜV Rheinland’s verified LCA shows how fermentation-based Claessen Blue™ can reduce toxicity and mineral-resource impacts while remaining ready for industrial adoption.
Color in fashion is beautiful on the surface and intensely chemical underneath. For decades, traditional dye chemistry has depended on intermediates and reactions that inherently carry human-health and supply-chain risks.
The newly verified TÜV Rheinland LCA (ISO 14040/14044) for Claessen Blue™ shows what a safer color path can look like.
A Different Kind of Color: Fermentation Instead of Synthesis
Claessen Blue™ is produced through microbial fermentation, not multi-step petrochemical synthesis. This eliminates the high-risk intermediates and reaction routes that have historically shaped dye chemistry.
The LCA highlights two standout performance areas:
- Extremely Low Human Toxicity (cancer & non-cancer). A direct signal of reduced exposure risk for manufacturing workers and cleaner chemical profiles for brands.
- Strong Performance in Resource Use (minerals & metals). Indicating lower dependency on critical, non-renewable mineral resources.
For material, chemistry, and ESG teams, these are the metrics that drive compliance confidence and safer-chemistry roadmaps.
Why This Matters for Brands
Regulation is converging around hazard and toxicity control, not just climate:
- ZDHC MRSL enforcement
- EU Chemicals Strategy for Sustainability
- Safer chemistry scoring systems
- Toxicity and hazard disclosure requirements
Bio-based color directly reduces chemical risk at the source, supported by third-party verification. It offers brands a scientifically credible upgrade to supply-chain safety without compromising scalability or performance.
This isn’t just greener color. It’s demonstrably safer color.
Toward a Cleaner Color Ecosystem
Our goal at Chloris is to rebuild color using biotechnology: high-performing, scalable, and fundamentally gentler on people and the planet.
The TÜV LCA verification is an early proof point — a data foundation enabling brands to adopt safer chemistry with confidence.
The future of color can be beautiful, scientific, and responsible. And this is only the beginning.
