Who we are, how we got here, and what we build.

Production heritage

Our facility runs six dedicated production lines, each specialized to a single product category - gels, strips, powders, pastes, devices and applicator pens. This structure keeps cross-contamination risk low and tooling utilization high. We work direct with brand owners; there are no intermediary trading companies in the supply chain.

What sets the operation apart

  1. Single-category specialization

    We manufacture oral care exclusively. No personal care, no general consumer goods. Tooling, supplier relationships and SOPs are all optimized for one product family.

  2. Active-system breadth

    PAP, carbamide peroxide, hydrogen peroxide, and peroxide-free formulations available within the same facility. Customers can select the active system that fits their destination market's regulations.

  3. Turnkey OEM & ODM

    Packaging design, regulatory artwork, barcoding and inserts are scoped into every production order. There are no separate per-order design fees on confirmed runs.

  4. No fixed MOQ

    No rigid minimum order — pilot runs are flexible and quantities are negotiated around your formula and packaging. Pilot tooling carries over to production runs.

  5. Documented traceability

    Every batch carries lot identifiers, Certificate of Analysis, and supplier traceability for active ingredients. Full documentation suite (ISO 13485, FDA, CE, GMP, BSCI, RoHS, MSDS) available on request.
