Abstract

Soaps are the sodium salts or potassium salts of stearic acids. They are prepared by the saponification process, which is, reacting the oil which contains triglycerides with Caustic soda (NaOH) to give the soap. In the present work prepared total ten numbers of herbal soaps by using Guava and Neem leaves extract with 5 different types of oils (Coconut, Teel, Olive, Mustard and Sunflower). In this process used turmeric, indigo, milk powder, henna and coffee powder as a colouring agent and Lemon grass leaves extract as a flavouring agent. After preparation of soaps analyzed different properties of soap such as foaming capacity, yield percentage, lathering power, cleansing power, hardness and moisture content of samples. After analysis conclude that the soap prepared with Coconut oil is best among them and soap with Sunflower oil is poor quality. It has been also concluded that the soap prepared by guava leaf extract can be used for washing wounds.due to anti bacterial properties.
