Tackling Inventory Pain Points: How Bio-based Dyes Solve Denim Yellowing for Long-Term Value
At Intertextile Shanghai, Chloris demonstrated how Claessen Blue™ combines clean fading, verified fastness and drop-in compatibility to reduce denim yellowing across the value chain.
At Intertextile Shanghai, Chloris demonstrated how bio-based color addresses real business pain points through anti-yellowing innovation.
The culprit? Conventional indigo degrades into Isatin — yellow by nature. Claessen Blue™ changes that.
Its pyridone structure has strong intermolecular hydrogen bonding, which makes it more stable than indigo. Even degradation produces colorless byproducts. Clean fading, less yellowing.
Drop-in compatible. No equipment changes. Chlorine-free washing.
Third-party verified:
- Light fastness: 4+ (industry: 2–3)
- Ozone fastness: 4+ (industry: 2–3)
One solution across the chain: Retail | Warehouse | Consumer | Production — extended life, less waste, fewer returns.
