Abstract

The goal of this project is to make soap from the glycerol produced from biodiesel. During this process 20mL-30mL of glycerin from three different funnels are being recorded from the process of transesterification. Once the glycerin is collected the process of making the soap is begun. For the first portion a beaker is placed on a digital scale to record grams. First 152g is put into a beaker and 58.85g of lye NaOH is added. After 220g of tallow, 100g of caster oil, and 80g of coconut oil is added into a pot, all oils are melted. Then the mixture is blended with a hand blender until trace. Next in a separate beaker 60g of glycerin is added to 150g of alcohol. Once mixed together it will be added to the soap mixture and mixed with a hand blender once more and quickly covering it. While the soap mixture is cooking add 45g of sugar into 90g of distilled water after warming it up. Once the solution has hardened in the mold completely it is tested for pH. The soap trials so far have been around 10.2-10.3 while the soap itself is at the level of hardness that is expected and completely opaque. While the pH is higher than the average pH for soap, the consistency is accurate. In the future tests for cleansing and condition will be taken.
