Seprify Secures €13.4M to Replace Titanium Dioxide with Cellulose
▼ Summary
– Swiss startup Seprify has raised €13.4 million to scale its cellulose-based alternative to the industrial whitener titanium dioxide, with IKEA as a strategic backer.
– The company’s technology was inspired by the natural, structure-based whiteness of the Cyphochilus beetle and engineers cellulose particles to scatter light effectively.
– Titanium dioxide (E171) is a major global market but is now banned in food in the EU and Switzerland due to safety concerns, creating demand for alternatives.
– Seprify’s cellulose-based products offer comparable whitening and UV-blocking performance with an estimated 80% lower CO₂ footprint and are already at an advanced stage of industrial validation.
– The company has secured a significant commercial partnership with IKEA and is engaging with over 100 customer organizations, positioning it strongly in the competitive market.
A Swiss startup has secured significant funding to commercialize a natural, cellulose-based replacement for titanium dioxide, a common but controversial whitening agent. Seprify recently raised €13.4 million in a Series A round to scale its platform, which engineers cellulose to mimic the light-scattering properties of the industrial pigment. The investment round features strategic backing from Inter IKEA Group, highlighting the material’s potential for broad industrial application.
The company’s foundational insight came from an unlikely source: a Southeast Asian beetle. Researchers observed that the Cyphochilus beetle achieves a brilliant white appearance not through pigments, but through the intricate microscopic structure of its scales, which efficiently scatter light. This natural engineering inspired Seprify’s founders to explore whether cellulose, the planet’s most abundant biopolymer, could be structured to produce a similar optical effect.
For decades, titanium dioxide (TiO₂ or E171) has been the global standard for creating whiteness and opacity in countless products, from candies and sauces to sunscreens and paints. Valued as a $16 billion market, it was long assumed to be inert. However, growing regulatory scrutiny has upended this assumption. The European Union banned its use in food in 2022 after safety authorities raised concerns about particle accumulation in the body, with Switzerland and other regulators following suit.
This regulatory shift left manufacturers scrambling for alternatives. Many existing options, such as calcium carbonate or rice starch, often compromise on performance, present their own regulatory questions, or force costly product reformulations. Seprify positions its cellulose-based solution as a high-performance, sustainable answer to this problem.
The core of the technology lies in precise control over cellulose microstructure. By engineering particles to scatter light in a specific way, the company can replicate the whitening, opacifying, and UV-blocking functions of TiO₂ through physical structure alone, eliminating the need for synthetic pigments. Seprify has developed three product lines from this platform: SilvaAlba for food-grade whitening, SilvaLuma as a natural SPF booster in suncare, and SilvaFilla for coatings and inks. All are derived from certified wood pulp and claim to generate roughly 80% fewer carbon emissions than traditional titanium dioxide production.
Having progressed to advanced technology readiness levels, Seprify’s materials are now being tested in real-world industrial settings. The company has established a commercial partnership with Danish color firm Oterra and is engaged with over 100 potential customers, moving from initial evaluations toward early commercial supply.
The participation of Inter IKEA Group is a strategic endorsement that extends beyond capital. IKEA has been actively investing in sustainable material innovations that can integrate seamlessly into existing manufacturing and recycling systems. Coatings and surface treatments are a logical area of interest for the furniture giant, suggesting a clear pathway for Seprify’s technology into consumer goods.
While the market for alternatives is competitive, Seprify differentiates itself with a compelling combination: a bio-inspired design principle, rigorous product validation, and a powerful commercial partner in IKEA. The company’s total funding now surpasses €22 million as it aims to transform a massive global market by proving that nature’s own structures can out-engineer a century-old chemical staple.
