Meets Q/RXSW 0044H cosmetic raw material standard with stricter microbial controls (≤500 CFU/g vs ≤1,000 for food grade) and full 4-metal heavy metal panel.
Additional testing for Pseudomonas aeruginosa and Thermotolerant Coliform Bacteria beyond food-grade requirements — essential for cosmetic safety compliance.
Four-metal ICP testing (Hg/Pb/As/Cd) to cosmetic-grade limits — meeting EU Cosmetics Regulation and major international cosmetic ingredient standards.
High water solubility with clear, low-turbidity aqueous solutions — ideal for serum, essence, and gel-type topical formulations requiring visual clarity.
CS is a native component of the extracellular matrix and skin dermis — making it a well-tolerated, low-sensitization cosmetic active ingredient.
INCI name: Sodium Chondroitin Sulfate. Fully documented for EU CPNP notification and global cosmetic product registrations.
Cosmetic grade Chondroitin Sulfate provides structural support and hydration in topical formulations.
Chondroitin sulfate supports skin hydration, elasticity, and extracellular matrix integrity — increasingly used in premium anti-aging serums and face creams.
High water-binding capacity makes CS effective as a humectant in moisturizers, toners, and hydrating masks — often combined with hyaluronic acid.
Used in professional skincare targeting dermal matrix support, skin firmness, and post-procedure recovery formulations.
CS can improve hair moisturization and surface smoothness in conditioners and hair masks — particularly for damaged or chemically treated hair.
EP compliant grade for drug products and medical device applications.
