Formulation & Evaluation of Hand Sanitizer Gel containing Infusion of Butterfly Pea Flower (Clitoria Ternatea) as Antibacterial Agent

Abstract

The increasing awareness regarding hand hygiene and the growing demand for herbal-based personal care products have encouraged the development of natural and effective hand sanitizing formulations. The present research work focuses on the formulation and evaluation of a herbal hand sanitizer gel containing an infusion of Butterfly Pea Flower (Clitoria ternatea) as a natural antibacterial agent. Butterfly pea flower is well known for its rich phytochemical constituents such as flavonoids, anthocyanins, tannins, and phenolic compounds, which possess significant antimicrobial and antioxidant properties. The primary objective of this study was to formulate a stable, safe, and effective herbal hand sanitizer gel using the infusion of butterfly pea flower and to evaluate its physicochemical as well as antibacterial characteristics.
The hand sanitizer gel was prepared using suitable gelling agents, humectants, preservatives, and other excipients along with the herbal infusion. Antibacterial activity of the formulation was assessed against common pathogenic microorganisms using standard microbiological methods. The prepared formulation exhibited satisfactory physical properties with good consistency, smooth texture, acceptable pH, and enhanced spreadability. The antibacterial studies demonstrated effective inhibitory action against selected bacterial strains, indicating the potential of butterfly pea flower infusion as a natural antibacterial ingredient in hand sanitizer formulations. The study concludes that the formulated herbal hand sanitizer gel containing butterfly pea flower infusion can serve as a promising alternative to conventional chemical-based sanitizers due to its antibacterial efficacy, natural origin, skin-friendly nature, and aesthetic appeal. The developed formulation may contribute to the advancement of herbal healthcare products with improved consumer acceptance and reduced side effects.
