Introduction
Hand hygiene is universally recognized as one of the most effective public health interventions for preventing the spread of infectious diseases. In situations where soap and water are unavailable, hand sanitizers provide a rapid and practical hygiene solution.
Conventional alcohol-based sanitizers may cause skin dryness, irritation, and barrier disruption with repeated use. Herbal formulations incorporating medicinal plant extracts offer a potentially safer and more skin-compatible alternative.
Materials and Methods
The polyherbal sanitizer was formulated using neem, tulsi, aloe vera, and mint extracts combined with isopropyl alcohol, glycerin, and distilled water.
Herbal extracts were prepared through ethanolic extraction and fresh aloe vera gel processing. The final sanitizer was prepared as a hydroalcoholic formulation with uniform mixing and pH adjustment.
Evaluation Parameters
- Organoleptic assessment
- pH determination
- Bulk density
- Tapped density
- Skin irritation testing
- Stability studies
Results and Discussion
The developed formulation showed acceptable cosmetic and practical characteristics suitable for hand hygiene applications.
- Appearance: Green
- Odor: Pleasant herbal
- Texture: Smooth and homogeneous
- pH: 5.5–7.0
- Bulk Density: 0.75 g/mL
- Tapped Density: 0.857 g/mL
- Skin Irritation: None observed
- Stability: No significant changes observed
Neem contributed antimicrobial and anti-inflammatory properties. Tulsi enhanced antimicrobial and antiviral activity. Aloe vera improved moisturization and reduced alcohol-induced dryness. Mint added cooling, antimicrobial, and sensory benefits.
Conclusion
The polyherbal hand sanitizer demonstrated acceptable physicochemical properties, favorable skin compatibility, and short-term stability, suggesting potential as a safe and cosmetically acceptable hygiene formulation.
Further antimicrobial efficacy testing, long-term stability evaluation, and expanded dermatological studies are recommended before commercial application.
