Overview

RADIUS has built a reputation as one of America's most innovative natural oral care companies, and their Natural Biodegradable Silk Floss exemplifies why. This isn't just silk floss—it's hand-spun silk sourced from the CORSEDA fair trade cooperative in the Colombian mountains, supporting over 80 families who practice traditional sericulture. Every spool connects your daily oral hygiene routine to sustainable livelihoods across continents. The floss is infused with organic virgin coconut oil and coated in organic carnauba wax, creating a smooth glide that effectively removes plaque without the synthetic coatings found in conventional flosses. Coconut oil provides natural antimicrobial properties, while carnauba wax—derived from Brazilian palm leaves—ensures the floss moves effortlessly between teeth without shredding. What makes RADIUS silk floss stand out is its 100% plastic-free design. The packaging isn't just recyclable—it IS the dispenser. The paperboard box features an integrated cutting edge, eliminating the need for any plastic components entirely. This is genuinely zero-plastic dental floss, from the compostable silk to the recyclable cardboard. The environmental credentials are impeccable: RADIUS silk floss is free from fluoride, PFAS, glutens, preservatives, artificial sweeteners, GMOs, unnatural coloring, phthalates, and parabens. The silk itself biodegrades in 60-90 days—compared to 50-80 years for nylon floss. When you dispose of RADIUS floss, you're not adding to the microplastic crisis that's contaminating oceans and human bloodstreams worldwide. At under $7 for 33 yards, RADIUS offers one of the most affordable entry points into truly plastic-free, silk-based dental floss. For anyone curious about natural floss but hesitant about premium pricing, RADIUS removes the barrier while maintaining uncompromising quality standards.

Frequently Asked Questions

What makes RADIUS silk different from other silk flosses?

RADIUS sources their silk from the CORSEDA fair trade cooperative in Colombia—not mass-produced Chinese silk. This supports over 80 farming families practicing traditional, sustainable sericulture. The silk is hand-spun rather than machine-processed, resulting in a softer, more natural fiber. The organic coconut oil infusion is also unique to RADIUS.

How is the packaging truly plastic-free?

The RADIUS floss box is made entirely from recyclable paperboard with an integrated metal cutting edge. The box itself serves as the dispenser—there's no separate plastic case. When empty, the entire package goes in paper recycling. No plastic film, no plastic window, no plastic anything.

Why is this floss unscented? Can I get mint flavor?

RADIUS offers their biodegradable silk floss unscented to minimize ingredients and avoid synthetic flavoring. The coconut oil provides a subtle, pleasant taste. If you prefer mint, RADIUS offers other floss products with natural mint flavoring, though the silk version prioritizes ingredient purity.

Is silk floss effective compared to nylon floss?

Yes—silk effectively removes plaque and debris between teeth. The smooth fiber glides well, especially with the carnauba wax coating. Some users actually prefer silk because it's gentler on gums. The key difference is environmental: silk biodegrades in weeks while nylon persists for decades and sheds microplastics.

Can I compost RADIUS silk floss?

Absolutely. Pure silk is a natural protein fiber that composts completely—home compost or municipal composting both work. The packaging is recyclable paperboard. Nothing in this product will persist in the environment like conventional plastic floss and dispensers.
