Soaps and detergents are essential to personal and public health. They safely remove germs, soils and other contaminants and help us to stay healthy and make our surroundings more pleasant.   Soaps are made from fats and oils or their fatty acids. In this experiment, the lobsters will understand the terms: soap and saponification. In this experiment, each individual will identify the materials which are required for the preparation of soap, understand the use of common salt in saponification process, understand the alkalies required for the preparation of hard and soft soaps, understand the procedure of saponification process, and acquire the skill to perform the preparation of soap in lab

In this experiment , we used plant oils and sodium hydroxide to create four soaps via saponification reactions. Saponification is the process in which triglycerides are combined with a strong base to form fatty acid metal salts during the soap-making process. The distribution of unsaturated and saturated fatty acid determines the hardness, aroma, cleansing, lather, and moisturizing abilities of soaps. we first created labeled flags for each of the stirring straws by affixing a small square of tape to the straw. With the marker, label the flag with the corresponding test tube number. Then For 15 minutes of stirring the contents of each test tube in hot water we started to see clumps of soap form. Finally , we compared the suds production and precipitation of the soaps in the presence of distilled water and hard water.

In conclusion we made four soaps out of plant oils which were: canola oil, corn oil, coconut oil, and vegetable oil. We examined the efficacy of soaps in both distilled and hard water, and under experimental conditions we compared the performance of soaps and detergents. Since 2020 we have all been impacted by covid - 19 and one of the main defenses towards covid is washing your hands with soap. Washing your hands properly with soap and water can help prevent the spread of the germs like viruses and bacteria. It was overall a great experience to make soap from scratch.
