Sodium Chondroitin Sulfate is a sulfated glycosaminoglycan and sodium salt of chondroitin sulfate used as a specialty cosmetic ingredient in skin-care and hair-care formulations. It is a naturally derived polysaccharide associated with connective tissue and is composed of repeating disaccharide units containing N-acetylgalactosamine and glucuronic acid, with sulfate groups attached to the polysaccharide chain.
In cosmetic applications, Sodium Chondroitin Sulfate is primarily associated with skin conditioning, hair conditioning and antistatic functions. Its polyanionic polysaccharide structure provides strong interaction with water and can contribute to the conditioning characteristics of aqueous cosmetic systems.
Commercial Sodium Chondroitin Sulfate can be obtained from animal-derived cartilage or produced through other controlled processes depending on the specific material. The source and manufacturing process should be clearly documented because they can influence composition, molecular weight, sulfate distribution and other quality characteristics.
The INCI name is SODIUM CHONDROITIN SULFATE. The commonly reported CAS identifiers are 9007-28-7 and 9082-07-9, with EC Number 232-696-9. Cosmetic ingredient references list both CAS numbers for this INCI identity.
CAS 9082-07-9 specifically identifies Sodium Chondroitin Sulfate / Chondroitin Sulfate Sodium, while 9007-28-7 is also used in records associated with chondroitin sulfate. For an SDP commercial product, the CAS shown on the final COA and regulatory documentation should match the actual grade being supplied.
Sodium Chondroitin Sulfate is a polymeric glycosaminoglycan rather than a conventional small molecule. Therefore, a single fixed molecular weight is not representative of commercial material. Its molecular-weight distribution, degree of sulfation and composition can vary according to source and manufacturing process.
Sodium Chondroitin Sulfate is used primarily as a skin-conditioning and hair-conditioning cosmetic ingredient. Cosmetic ingredient databases also identify an antistatic function.
Its highly functionalized polysaccharide structure enables interaction with water and other formulation components. This makes it relevant to conditioning-focused formulations where hydration, film characteristics and sensory properties are important.
Sodium Chondroitin Sulfate can be formulated alongside other glycosaminoglycan and moisturizing ingredients, including Hyaluronic Acid, Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Glycosaminoglycans, Beta-Glucan, Polyglutamic Acid and Sodium PCA.
The actual formulation performance depends on molecular weight, concentration, degree of sulfation, ionic environment, pH and compatibility with other polymers and surfactants.
Sodium Chondroitin Sulfate can be incorporated into a variety of skin-care, hair-care and personal-care formulations.
Potential applications include:
Because it is a charged polysaccharide, compatibility should be evaluated carefully when combining it with strongly cationic or anionic formulation components.
The selected grade should also be evaluated for molecular weight, active chondroitin sulfate content, sulfate content, moisture, ash, pH, viscosity, residual protein and microbiological quality.
Sodium Chondroitin Sulfate is generally suitable for water-containing cosmetic formulations. Its hydration, viscosity and solution characteristics depend on molecular weight, concentration, ionic strength and processing conditions.
The Assay (HPLC) should not be populated with an arbitrary value. Sodium Chondroitin Sulfate is a polymeric glycosaminoglycan and requires an appropriate validated method for quantitative determination. The USP-NF monograph defines Chondroitin Sulfate Sodium as a sodium salt of sulfated glycosaminoglycan and specifies 90.0–105.0% on a dried basis for the monographed material; this should not automatically be treated as the specification of every cosmetic grade.
Useful quality-control parameters can include:
For animal-derived grades, source and processing documentation should be maintained. Cosmetic manufacturers should use the specifications and regulatory documentation applicable to the exact commercial grade.
Sodium Chondroitin Sulfate is a specialty cosmetic ingredient suitable for skin-conditioning, hair-conditioning and antistatic applications.
For B2B sourcing, manufacturers should evaluate the source, chondroitin sulfate content, molecular-weight distribution, sulfate content, moisture, ash, pH, residual protein and microbiological characteristics.
