Production and Analysis of Laundry Soaps from Blended Oils

Abstract

Stearic acids or any other fatty acids' sodium or potassium salts are what soaps are. The saponification method, which involves reacting triglyceride-containing oil with caustic soda (NaOH) to produce soap, is how they are made. However, the fatty acid makeup of various oils varies, which accounts for the various qualities of the soaps that are created from them. The aim of this study is to produce and analyze laundry soaps made from blended oils. Four different kinds of oils were used in this study. Four distinct soap samples were created by blending them in varying proportions. To determine which soap was the best, all soap samples were compared for their cleansing and lathering qualities, and the blend of palm kernel oil, palm stearin, beef tallow, and cotton seed oil at 3:1:3:3 ratio was determined to be the best with 76.4% total fatty matter (TFM) and 98.30% yield. The blends were examined for a variety of properties and compared with those found in the literature. The saponification and iodine values of the individual oils were also examined, and the results showed that soap made with the four oils in the 3:1:3:3:3 ratio had superior qualities to soaps made with other blends, was most cost-effective and ideal for laundry. Various characteristics of these samples were examined.
