Seprify's SilvaLuma Delivers a Green UV Boost

“With SilvaLuma, we’re proving that formulators no longer have to choose between performance and principles,” said Lukas Schertel, Ph.D., CEO and co-founder of Seprify. SeprifySwiss-based bio-materials firm Seprify has launched the cellulose-based SilvaLuma, which can reportedly double SPF values at just 3% dosage levels, per in vitro studies, which can lower UV filter loads without sacrificing protection.

• Trend watch: SPF Everything

The ingredient technology is derived from the company's prototype SkyWhite pigment and allows for reef-safe claims, while supporting non-greasy, non-sticky, matte finishes with no white cast.

SilvaLuma disperses in both oil and water phases, functions at 1-5% use levels, and can act as a stabilizer or co-emulsifier, making it highly versatile across formats, including:

• creams
• gels
• serums
• powders
• sticks

(Per the company, the ingredient technology can also act as a TiO₂ replacement in oral care.)

SilvaLuma is fully biodegradable, microplastic-free and compliant with EC 1223/2009 as a non-nano material.

The ingredient is produced using Seprify’s proprietary process, which reportedly achieves up to 70% lower greenhouse gas emissions compared to conventional pulp-based materials by leveraging low-energy processed, recycling all chemicals involved and sustainable sourcing from nearby pulp mills. 

Seprify’s process also eliminates chemical-intensive wastewater treatment and reduces energy demand by more than 50%.

“With SilvaLuma, we’re proving that formulators no longer have to choose between performance and principles,” said Lukas Schertel, Ph.D., CEO and co-founder of Seprify. “Building on the foundation of SkyWhite, SilvaLuma delivers targeted SPF-boosting power with refined validation and commercial focus. By controlling how cellulose structures interact with light, we provide mattifying solutions and meaningful SPF enhancement in a cleaner, simpler way—exactly what consumers expect from modern beauty.”
