        abstract = {The increasing concern over the adverse effects of synthetic chemical repellents has created a need for safe, eco-friendly alternatives. The present research aims to develop and evaluate a herbal lizard repellent formulation using custard apple (Annona squamosa) seeds and neem (Azadirachta indica) leaves, which are rich in bioactive phytoconstituents with repellent potential. The extracts were prepared by aqueous extraction and formulated into a liquid dosage form with a suitable preservative to enhance stability.

The formulated repellent was subjected to physicochemical and stability evaluation, including organoleptic characteristics, pH determination, viscosity measurement, and accelerated testing as per standard guidelines. Stability studies were conducted at room temperature, 4°C(±2) and accelerated conditions (40°C ± 2°C) over a defined study period. The formulation exhibited a slightly acidic and stable pH, while viscosity showed a marginal decrease under accelerated conditions, attributable to temperature-induced molecular mobility. No significant changes appearance, odor, or phase separation were observed during the study.

The findings indicate that the developed herbal formulation demonstrates good physical stability, safety, and environmental compatibility, supporting its potential use as a natural alternative to synthetic lizard repellents. Further studies on repellency efficacy and long-term stability are recommended to establish its practical applicability.},
