PHA isn't new. Making it work at commercial scale in oral care accessories is. Here's what we built — and why it's genuinely different.
Polyhydroxyalkanoates (PHAs) are polyesters produced naturally by bacteria when they're fed a carbon source like sugars or plant oils. The bacteria store the polymer as energy — the same way our bodies store fat.
PHB (Polyhydroxybutyrate) is the most commercially viable PHA polymer. It's naturally synthesized and naturally degraded — by the same microbial processes that create it.
Magic Materials PHA/PHB currently blends PHB with Nylon-6 to achieve the mechanical performance required for daily oral care use. Nylon-6 provides the flex, rigidity, and tensile strength needed at commercial scale today. Our target long-term formulation replaces Nylon-6 with Nylon-4 — a biodegradable nylon — as we work with manufacturing partners to bring Nylon-4 to commercial-scale production.
Bacteria are fed a renewable carbon feedstock (sugars, plant oils) and produce PHB intracellularly as energy storage granules.
PHB granules are extracted from the bacterial cells, purified, and processed into resin pellets.
PHB resin is currently blended with Nylon-6 in a proprietary ratio to achieve target mechanical properties for injection molding. We are actively developing a Nylon-4 formulation — a biodegradable nylon alternative — for transition as commercial-scale supply matures.
The compound is injection-molded into finished tongue scrapers and floss picks to partner specifications.

Most biodegradability claims are technically true. Most are also misleading. Here's the distinction that matters.
Biodegrades in home compost, soil, fresh water, and open ocean marine environments — no special facility required. Degraded by naturally occurring microbial activity at ambient temperatures.
Biodegrades only in industrial composting facilities at temperatures above 140°F — which most municipal facilities don't accept and most consumers can't access. Not marine-safe.
Does not biodegrade. Period. Petroleum-based polymers persist in the environment for hundreds of years. "Recyclable" claims don't change this — plastic recycling rates are below 10% globally.
"Unlike PLA (polylactic acid), PHA doesn't require industrial composting to biodegrade. It breaks down in soil, fresh water, and — critically — marine environments. That's the distinction that actually matters."
The PHA resin in our products holds certifications from BPI, TÜV Austria, TÜV SÜD, and the U.S. FDA. Marine and freshwater biodegradability, home and industrial compostability, soil biodegradability, food contact, chemical safety, PFAS, and product carbon footprint.
None are self-declarations. Every certification was issued by an independent, accredited body. Documentation is available to qualified partners under NDA.
Independently certified by TÜV Austria. Covers biodegradation in marine water environments.
Certified by both BPI and TÜV Austria (OK compost HOME). Biodegrades at ambient home compost temperatures without industrial equipment.
Effective Food Contact Notification from the U.S. FDA. Required for oral care products used in the mouth.
Carbon footprint of the PHA resin independently verified by TÜV SÜD under ISO 14067.
