Product Name: Cosmetic Grade PDRN (Polydeoxyribonucleotide)
CAS No.: 100403-24-5Molecular Formula: (C??H??N?O?P)?
Molecular Weight: 1000–5000 Da (customizable according to requirements)
Product Grade: Cosmetic Grade (complies with international cosmetic raw material safety standards)
Source: Salmon milt extraction (biological enzymatic hydrolysis & purification)
PDRN (Polydeoxyribonucleotide) is a natural biomacromolecule extracted from high-quality salmon milt. It is a polymer composed of deoxyribonucleotide monomers linked by phosphodiester bonds. As a functional cosmetic raw material, it has excellent biocompatibility and skin-friendly properties. It can effectively promote skin cell proliferation and repair, regulate skin microcirculation, and exert anti-inflammatory, moisturizing and anti-aging effects. It is widely used in high-end skincare products such as repair serums, anti-wrinkle creams, and post-sun repair products.
