Chemical Structure & Core Properties
Source → Chitosan Conversion
| Source: Chitin | Process | Result: Chitosan | Key Mechanism |
|---|---|---|---|
| Found in crustacean shells & fungal cell walls. | Alkaline Deacetylation (NaOH) | Primary Cationic Polysaccharide | Removal of acetyl group exposes positive charge, enabling binding to skin/hair. |
Source Group: N-acetyl group (-NHCOCH₃)
Result Group: Free Amine Group (-NH₂)
Degree of Deacetylation (DD)
| Grade | Value |
|---|---|
| Standard Grade | 70–85% |
| Cosmetic Grade | ≥90% |
Higher DD (>95%) increases antimicrobial efficacy and bioactivity.
Molecular Weight (MW)
| Type | Range | Primary Function |
|---|---|---|
| High MW | 50–500 kDa | Film Forming |
| Low MW (COS) | 2–5 kDa | Penetrating |
Viscosity Impact: High MW creates thicker gels; Low MW allows lightweight serums and deeper absorption.
Solubility Profile
pH Sensitivity: (pKa ~6.5)
Effective Solubility: pKa ~6.3
| Condition | Solubility |
|---|---|
| Water (Neutral) | Insoluble |
| Dilute Acids | Soluble |
