Sodium Hyaluronate (Hyaluronic Acid) Cosmetic Grade
Número CAS: 9067-32-7
Sodium Hyaluronate Cosmetic Grade is the gold-standard humectant in skincare, capable of holding up to 1000 times its own weight in water to deliver immediate plumping and long-lasting hydration. Available in high molecular weight (1–1.8 MDa, forms a surface moisture-retention film) and low molecular weight (5–200 kDa, penetrates deeper for structural hydration), enabling layered hydration strategies. Used at 0.01–2% across toners, serums, sheet masks, and moisturizers.
