In the fields of medical aesthetics and regenerative medicine, polydeoxyribonucleotide (PDRN) has become a highly regarded core active ingredient. As a leading supplier of biological raw materials, SINOWAY leverages its technological expertise and strict quality control to offer a highly competitive high-purity natural PDRN, providing downstream customers with reliable and efficient solutions.

1. Ultra-High Purity — Setting Industry Standards

    SINOWAY's PDRN is tested with a purity exceeding 98.5% by HPLC, far surpassing typical market levels. High purity ensures more consistent biological effects, lower immunogenicity, and enhanced safety, laying a solid foundation for pharmaceutical and high-end cosmetic applications.

2. Dual-Quality Grades: Injectable & Cosmetic

    The product meets both injectable-grade and cosmetic-grade standards, making it suitable for a wide range of applications such as hydro-facials, micro-needling, and regenerative skincare products. This flexibility enables clients to develop diverse product portfolios based on a single high-quality raw material.

3. Strict Heavy Metal and Microbial Controls

    SINOWAY places utmost importance on product safety. Every batch complies with the following stringent limits:

• (1) Heavy metals: Cadmium (Cd) ≤5 mg/kg, Lead (Pb) ≤10 mg/kg, Mercury (Hg) ≤1 mg/kg, Arsenic (As) ≤2 mg/kg

• (2) Microbial limits: Total bacterial count <50 CFU/g; Mold and Yeast <50 CFU/g

• (3) Pathogens: Pseudomonas aeruginosa, E. coli, and Staphylococcus aureuswere not detected.

    These specifications significantly exceed general industry requirements, ensuring safety and compliance for end products.

4. Optimal Molecular Weight and Reliable Sourcing

    The average molecular weight of the product is controlled under 650 kDa (approx. 1050 bp), optimizing cellular absorption efficiency and bioactivity. While currently sourced mainly from salmon, the company is actively developing plant-based PDRN to meet diverse market demands and sustainability trends.

5. USDMF Filing: International Compliance Passport

    SINOWAY's PDRN has completed filing with the  USDMF. This provides a solid regulatory foundation for clients seeking to enter international markets.

6. Large-Scale Production and Cost Efficiency

    With an annual production capacity of over 5 metric tons, SINOWAY can stably supply global markets. While maintaining extremely high quality, the company offers competitive pricing, delivering comprehensive value described as “high quality at optimal cost.”

    Thanks to its advanced purification technology, strict quality control, application flexibility, and international compliance, SINOWAY''s PDRN stands out as one of the few raw materials in the industry that simultaneously offers high purity, safety, production capacity, and cost-effectiveness. It provides downstream companies not only with a superior raw material but also with powerful biotechnological support to accelerate product innovation and enhance brand differentiation.
