CHITOSAN ASCORBATE.

Valuable CAS 135322-32-6 / ANTIOXIDANT, FILM FORMING, SKIN CONDITIONING

A sophisticated biotechnological hybrid that fuses the structural, film-forming benefits of marine-derived chitosan with the antioxidant potency of Vitamin C. This polycationic complex creates a breathable, humectant shield while enhancing the delivery of active molecules into the deeper layers of the epidermis.

Science

Mechanism of Action

Chitosan Ascorbate utilizes its unique positive ionic charge to anchor to the naturally negative surface of the skin. Once applied, it performs four distinct actions: it forms a non-occlusive moisture barrier, destabilizes harmful bacterial membranes, neutralizes reactive oxygen species via its ascorbate moiety, and transiently modulates tight junctions in the skin to increase the bioavailability of co-formulated ingredients.

Key findings

  1. 01 Accelerates dermal repair and purulent wound closure by up to 5-7 days at therapeutic concentrations.
  2. 02 Demonstrated superior DPPH radical scavenging activity at 0.025 mg/mL compared to standard chitosan.
  3. 03 Effective as a mucoadhesive delivery system at 2% to significantly enhance the penetration of actives across skin barriers.

While effective as a nanoparticle stabilizer at 0.1%, functional film-forming and penetration-enhancing benefits typically require concentrations between 0.5% and 2.0%. Presence below 0.1% is likely for label claims rather than physiological impact.

Stability

Maintains peak stability in acidic aqueous environments below a pH of 6.3. It is prone to precipitation in alkaline conditions (pH > 7.0) and requires airless packaging to prevent the oxidation of the ascorbic acid component.

Synergies

  • Non-ionic antioxidants
  • Low-molecular weight actives
  • Acidic stabilizers

Conflicts

  • Anionic surfactants like Sodium Lauryl Sulfate
  • Anionic polymers such as Carbomer
  • High ratios of Hyaluronic Acid
  • Strong oxidizing agents
