Formulation and Quality Evaluation of Herbal Soap Cosmeceutical using Essential Oils & Natural Ingredients by Saponification Reaction

Abstract

Herbal soap was formulated using the leaf and bark extract of Azadirachta indica (Neem), Ocimum tenuiflorum (Tulsi), Sapindus mukorussi (Indian soapberry/Reetha) and Acacia concinna (Shikakai) powder. Ayurvedic cosmetics are also known as herbal cosmetics. The natural content in the herbs does not have any side effect on the human body (Joshi & Pawar, 2015). Most herbal supplements are based on several botanical ingredients with long histories of traditional or folk medicine usage. Among the numerous botanical ingredients available in the market today (Saikia et al., 2006). Numerous chemical toxins and microorganisms present in the atmosphere may cause chemical infection and damage to skin. Cosmetics alone are not sufficient to take care of skin and body parts. Neem (Azadirachta indica) tree has attracted worldwide prominence owing to its wide range of medicinal properties. Neem leaves and its constituents have been demonstrated to exhibit anti-inflammatory, antihyperglycemic, antiulcer (Subapriya & Nagini, 2005), antimalarial, antifungal, antibacterial, antimutagenic and anticarcinogenic properties. Herbal soap ingredients were used reetha, neem, shikekai and tulsi., in which neem leaf and seed were found effective against some dermatophytes. Shikakai and Reetha act as a detergent and have cleaning and foaming activity and Tulsi shows antiviral activity (Amrutkar, 2022). This study focuses on the development and assessment of a herbal soap that includes glycerin, coconut oil and ajwain oil (Trachyspermum ammi), which is recognized for its antibacterial and antifungal qualities. The soap was made using the conventional saponification method, and its moisture content, foam retention, and physical attractiveness were evaluated. The finished soap had a good look, a pleasing smell, and a yellowish-brown tint and also had different colours because of using food grade colours. It retained a 12 cm foam height and 31% moisture content. These results imply that herbal soap containing ajwain oil and other organic components can successfully improve skin health and offer antibacterial defense. The growing consumer preference for natural and environmentally friendly personal care products is in line with this, underscoring the potential applications of herbal formulations in the cosmetics and pharmaceutical industries.
