Private Label Iontophoresis Electrodes | Ag/AgCl OEM | TOP-RANK
Technical manufacturing of iontophoretic electrodes for transdermal drug delivery. Features Ag/AgCl redox stability and pH-buffered reservoirs to prevent chemical burns during DC therapy.
Product Overview
These are active transdermal components designed for private label integration into iontophoretic drug delivery systems. Unlike AC-based TENS pads, these utilize a Silver/Silver-Chloride (Ag/AgCl) interface to manage constant Direct Current (DC). We provide these as white-label components for pharmaceutical R&D and clinical brands requiring a stable ionic bridge for localized medication delivery.
Key Features
Chemical Burn Prevention (pH Buffering)
Constant DC therapy generates hydroxyl ions (OH-) at the cathode, leading to NaOH buildup. If the interface is not buffered, it results in high-pH chemical burns. We integrate a proprietary pH-balancing layer within the fiber reservoir to lock the skin-contact pH between 4.5 and 6.5 for the duration of the 20-40 minute delivery cycle.
Ag/AgCl Redox Stability
Carbon-only electrodes polarize under DC, causing a rapid spike in resistance and an immediate drop in drug delivery rate. By controlling the Silver-to-Silver-Chloride ratio, we ensure the impedance stays flat. This is critical for pharmaceutical protocols requiring a linear dosage curve.
Peripheral Fluid Isolation
Leakage of the drug solution to the adhesive border creates a low-resistance "short circuit" at the patch edge. Our private label pads use a high-density isolation ring to contain the medication within the reservoir, preventing edge-effect burns and ensuring 100% current density through the drug-saturated zone.
Applications
- Dermatology: Hyperhidrosis treatment (anticholinergics) and needle-free anesthesia (Lidocaine).
- Orthopedics: Active delivery of Dexamethasone Sodium Phosphate for localized inflammation.
- Aesthetic Medicine: Iontophoretic delivery of ionized serums and collagen precursors.
OEM & Private Label
We operate specialized production nodes in China and Vietnam to provide supply chain redundancy and logistics flexibility for global B2B clients.
- Custom Die-Cutting: Electrodes can be shaped to fit specific anatomical sites (e.g., joints, face, or underarms).
- Branding: Private label printing on the backing material and the multi-layer foil pouch.
- Reservoir Tuning: Modification of the fiber matrix to accommodate different drug viscosities and polarities.
Certifications
- Regulatory: FDA 510(k), CE (MDR), and UKCA.
- Systems: ISO 13485 and MDSAP.
- QC Protocols: Every production batch is tested for pH drift under a 4.0mA DC load and Ag/AgCl coating thickness (measured in microns) to ensure performance consistency across all lots.
FAQ
Q: Can these electrodes be reused for the same patient?
A: No. After one session, the Ag/AgCl layer is partially depleted and the pH buffer is consumed. Re-using the patch will result in non-linear drug delivery and an increased risk of pH-induced skin damage.
Q: How do you prevent drug-material interaction?
A: We use inert fiber matrices that do not bind to the ionized drug molecules. For new pharmaceutical compounds, we recommend compatibility testing to ensure the drug's potency is not compromised by the electrode substrate.
CTA
B2B project managers can request pH-drift stability reports and Ag/AgCl impedance data for regulatory filing support.
