The purpose of this project is to analyze the composition of fatty matter in cold process soap by extracting excess oil from soap and performing 13CNMR. The three oils which were used in the soap making process were olive oil for which oleic acid is the main fatty acid, castor oil for which ricinoleic acid is the main fatty acid, and grapeseed oil for which linoleic acid is the main fatty acid. Each soap contained 90% palm oil and 10% of the respective oil. It was found that composition of fatty matter in cold process soap does not differ depending on whether or not the minor oil was added early or late in the saponification process. In all three cases, the percent of unsaturated fatty acid is higher in the original oil from which each soap was made.
