widely used in herbal remedies for the treatment of various diseases in India. In Arunachal Pradesh, India, these plants are combined by traditional healers to treat.

Aim of the study:

The study aimed to formulate and evaluate a herbal soap containing Citrus maxima extract. The plant material was collected, authenticated, and extracted using suitable methods.

Materials and methods:

Fresh peels of Citrus maxima were collected, dried, powdered, and used for the preparation of herbal soap using natural ingredients. The formulated soap was evaluated for physicochemical parameters, including pH, foam height, foam retention, moisture content, free alkali, alcohol insoluble matter, total fatty matter (TFM), hardness, and washability using standard methods. Organoleptic properties such as colour, odour, texture, shape, and appearance were also assessed. Skin irritation studies were performed to evaluate the safety of the formulation.

Results:

The formulated Citrus maxima herbal soap showed satisfactory physicochemical properties with a pH of 8.5, good foamability and foam stability, 72% total fatty matter, low free alkali content (0.18%), and acceptable moisture content (10.40%). The soap exhibited moderate hardness, easy washability, and no signs of skin irritation. Organoleptic evaluation revealed an attractive orange colour, pleasant citrus odour, soft, glossy texture, and translucent appearance, indicating good quality and consumer acceptability.

Conclusion:

The study successfully formulated a Citrus maxima herbal soap with good physicochemical properties, acceptable organoleptic characteristics, and no skin irritation. The findings suggest that the formulated herbal soap is safe, effective, and suitable for skin care applications.
