This action research explores the chemical interaction between organic botanical extracts and a
transparent soap base within an undergraduate laboratory setting. Conducted as a student-led
practical intervention aligned with the Applied Chemistry curriculum, the study investigates the
spontaneous behavior of raw rose extract without synthetic stabilizers. The experiment utilized a
controlled ratio of 200g transparent glycerin base to 15 mL fresh Rosa indica juice. The entire
formulation process and its immediate transitions were fully observed and validated live by the
subject teacher and a peer cohort. Upon formulation, a two-stage color shift was observed: an
immediate deep green coloration due to the structural transition of natural anthocyanins
interacting with co-existing yellow flavonoids in an alkaline matrix (estimated pH 9.0–9.5). This
intermediate phase stabilized into a translucent light brown with a distinct brownish-orange hue
after a 24-hour curing period. To complete the action-research cycle, the resulting disc-shaped
soaps were evaluated via a direct hand-washing trial by a student peer cohort (N=5) immediately
upon unmolding. The findings document the natural oxidation pathway of botanical pigments,
offering a reproducible, synthetic additive-free alternative for personal care while demonstrating
the reflective learning value of faculty-supervised, classroom-based product synthesis.
