TABLE 5.
Applications of chitosan derivatives and chitosan-based nanocomposites in cosmetics.
| Systems | Main findings | References |
|---|---|---|
| Carboxymethyl chitosan | A remarkable moisturizing effect due to the polymer’s ability to form a hydrated layer on the skin’s surface, preventing water loss | Chaiwong et al. (2020) |
| Chitosan-lemongrass essential oil films | Application as antioxidant and antimicrobial care masks with high flexibility and permeability, without cytotoxic risks | Gaspar et al. (2022) |
| Methylcellulose-chitosan smart gels | Heat protection with chitosan that acts like a film on the hair, protecting it from heat damage. Applied like an ultra-hold hairspray on hair, it fixes the style for hours | Hartson et al. (2022) |
| Carboxymethyl chitosan | Safety and efficacy of injectable soft tissue devices for the intradermal treatment of age-related skin defects. Significant improvement in skin hydration, firmness, and elasticity | Philippart et al. (2021) |
| Thymoquinone-loaded chitosan nanoparticles | Superior antimicrobial activity over time and a natural, effective, and lasting preservative effect in cosmetic products | Mondéjar-López et al. (2022) |
| Pomegranate juice-loaded chitosan derivative nanoparticles | Improved antioxidant and antimicrobial properties of skin emulsions with good storage stability. Higher sun protection factor | Bikiaris et al. (2020) |
| Carboxymethyl chitosan-mangosteen extract | Good moisturizing power for the skin and good deodorizing property against trans-2-nonenal odor, with antioxidant and antibacterial properties | Chaiwong et al. (2022) |
| Chitosan nanoparticles | A significant anti-sebum characteristic on the T-zone of the face after 4 weeks, without significant disruption of the skin barrier | Theerawattanawit et al. (2022) |
| N-[(2-hydroxy-3-trimethyl-ammonium)-propyl] chitosan chloride | Excellent antibacterial and mechanical properties, with desirable cell attachment and proliferation | Khalaji et al. (2021) |
| Chitosan/vitamin C complex | Enhanced antioxidant, moisturizing, antibacterial, and film-forming properties. High moisture retention, hygroscopicity, ability to scavenge hydroxyl radicals, and high stability | Liping et al. (2020) |
