Heat-Stable Professional Whitening Gel (No Cold Shipping Required)
A U.S. in-office whitening brand needed a high-potency peroxide gel that could withstand freight temperatures up to 50 °C without potency loss or phase separation. We engineered a water-based system using peroxide-compatible polymers and a radical-scavenger matrix to slow autocatalytic breakdown. The near-neutral pH improved patient comfort and minimized sensitivity. The result: <15% peroxide loss after 30 days at 50 °C, zero leakage, smooth non-drip chairside handling, and successful U.S. commercialization with repeat orders and a post-launch complaint rate below 0.3%.

High-Load Sublingual Film with Bitter Actives
A brand required a fast-dissolving oral thin film (ODF) delivering >35% active load while effectively masking strong bitter notes. We developed a sublingual film using taste-masking microencapsulation, an optimized PEG plasticizer system, and moisture-protective pouch packaging to preserve stability. The result: disintegration ≤40 seconds (USP <2040>), content uniformity CV ≤5%, and pouch residual moisture ≤3% at 6-month accelerated conditions. The product successfully scaled to continuous roll-to-roll manufacturing with >95% yield post die-cut.
