Salmon polynucleotide, commonly shortened to Salmon PN, is a DNA-derived polymeric raw material purified from salmon milt. On the product documentation this cosmetic grade is identified as Sodium DNA (CAS 9007-49-2). It is supplied as a white to off-white powder specified at an average molecular weight of at least 1,000 kDa and an assay of at least 90.0%.
That high-molecular-weight specification is what distinguishes this grade from lower-molecular-weight PDRN (polydeoxyribonucleotide) materials. PN and PDRN are used inconsistently across supplier listings, so we recommend comparing the supplied grade, average molecular weight, assay, solubility and batch COA rather than selecting a material by abbreviation alone.
This grade is a cosmetic raw material for topical formulation use. For injectable or medical-device applications, see our separate Pharmaceutical Grade Salmon PN (NewPN-P®).

At its specified molecular weight, this Salmon PN grade keeps the physical structure that matters for topical regenerative and conditioning formulations.
At ≥1000 kDa average molecular weight, the polymer forms an interconnected structure rather than remaining a simple linear chain.
The structure creates space that can support cell migration and material exchange in a formulation matrix.
The physical structure is compatible with fibroblast attachment, relevant for post-treatment and conditioning formulations.
Breaks down through normal physiological pathways; pH 6.0–10.0 supports compatibility with topical use.
A sample Certificate of Analysis is available on request, and current-batch COA data is supplied with quotations.
| Cosmetic Grade Sodium DNA / Salmon PN (this page) | Pharmaceutical Grade Salmon PN (NewPN-P®) | |
|---|---|---|
| Intended use | Topical skincare formulations | Injectable and medical-device applications |
| Typical formats | Serums, creams, post-treatment gels and masks | Sterile solutions, medical devices |
| Testing scope | Heavy metals, microbial limits, assay (this COA) | Additional sterility/endotoxin-relevant testing per pharmaceutical specification |
If your finished product is injected or classified as a medical device, contact us about NewPN-P® instead — the two grades are tested and documented differently and are not interchangeable.
Used in serums and creams aimed at conditioning, moisturizing, and softening the skin’s surface.
Included in soothing masks and repair gels marketed for use after microneedling, laser resurfacing, or chemical peels — as a topical conditioning ingredient, not a substitute for medical aftercare products.
Frequently paired with high molecular weight 透明质酸钠, where the hyaluronate contributes immediate surface hydration and film formation alongside PN’s structural properties.
Every batch is issued with a COA covering identity, heavy metals, microbial limits, and assay — available for download or on request for the current batch.
Average MW ≥1000 kDa, confirmed per batch, supporting the polymer’s structural properties in formulation.
50 g, 100 g, or 1 kg packaging, with custom packaging available on request.
Samples available for formulation testing before committing to bulk volume.
Cosmetic and pharmaceutical grade Salmon PN are manufactured and tested to different specifications so you can match the grade to your product type — see the comparison above.
Compare Salmon PN with other DNA polymer grades by molecular weight, source and purity level, and choose the grade that fits your formulation and product type.
Sodium DNA is the ingredient family name for DNA polymers purified from salmon milt, including both PDRN and PN. Salmon PN is the higher molecular weight fraction within that family (average MW ≥1000 kDa in this product), distinguished from PDRN’s shorter chains.
Both are purified from salmon milt DNA, but PN consists of longer, higher molecular weight chains (this product: average MW ≥1000 kDa) while PDRN is processed into shorter fragments. The longer PN chains form a network structure relevant to physical scaffolding, while PDRN’s shorter fragments are associated with faster cellular activity. See our Salmon PDRN page for the shorter-chain version.
No — this is our cosmetic grade material, tested and documented for topical formulations. For injectable or medical-device use, see our separate Pharmaceutical Grade Salmon PN (NewPN-P®), which is tested to a different specification.
No. This product is purified from salmon milt (fish-derived). If you need a plant-derived alternative, see our 植物源PDRN product.
523.37 is the molecular weight of the repeating nucleotide unit (the chemical building block), not the assembled polymer. The finished polymer’s average molecular weight — the figure relevant to its structural properties — is ≥1000 kDa, confirmed per batch COA.
A Certificate of Analysis is available on request, and current-batch COAs can be supplied with quotations. Contact us for TDS or additional documentation.
Standard packaging is 50 g, 100 g, or 1 kg. Contact our sales team for current MOQ, lead time, and sample availability.
Tell us your intended application, estimated quantity, destination country and packaging requirements. Include the document set you need (COA, TDS or SDS) and Renew will prepare the relevant product information and quotation.
