Preparation of Soap Using Different Types of Oils and Exploring its Properties

Mishra , Debesh (2013) Preparation of Soap Using Different Types of Oils and Exploring its Properties. BTech thesis.



Soaps are the sodium salts or potassium salts of stearic acids or any other fatty acids. They are prepared by the saponification process, which is, reacting the oil which contain triglycerides with caustic soda (NaOH) to give the soap. However different oils have different composition of fatty acids which are responsible for different properties of soaps made out of them. In the present work 5 different types of oils are taken. They are blended in various ratios to prepare 14 different samples of soap. Different properties of these samples were analyzed to see which soap is the best one. The cleansing and lathering properties of all samples were compared. The blend of coconut oil and castor oil at 3:1 ratio is found out to be the best with 76.8% of TFM and 89.46% of yield. The best blend is analyzed for various properties and they were compared with that given in the literature. The saponification values, iodine values of coconut oil and castor oil were found out and these values were also found for the blend. It was found that the blend was having SAP value of 230.4 and iodine value of 40 which are higher than the individual values. Thus soap prepared using blend of both these oils has better properties than the soaps prepared by individual oils.
