For the second part of the soap lab me and my partner Lily created a bar soap to compare to the liquid soap we have previously made. The bar soap was a much more complicated process than the liquid soap lab and required much more work with chemicals and natural oils and fats. For the previous liquid soap lab we used a store bought castile soap and just added oils, the bar soap we made was completely home made from start to finish and required us to make the lye.
The bar soap we were making consisted of lye and natural fats and oils. The lye was a mixture of sodium hydroxide and water, this solution is what gave the bar soap its cleaning properties. The purpose of the fats in the bar soap were to balance the effects of the lye, which on its own would be an irritant to the skin. The fats and oils hydrate and sooth the skin. The oils and fats we used were Olive oil, and coconut oil.
To make the bar soap we used a lye solution of 64.7 grams and 180 grams of olive oil and 135 grams of coconut oil and lemon oil . All of the oils were mixed together in one container except for the lemon oil, fragrances are added last. The lye was mixed in a separated container with the 171 grams of distilled water. When each of the separate mixtures were well mixed we put them together to start making the soap. Once the oils and lye were mixed together we noticed an immediate reaction. The mixture began to get hotter and harder and we noticed this was an exothermic reaction. For the lye and oils to react well to create the soap me and my partner Lily began mixing it rigorously. The mixing after time made the mixture thicker and that is exactly what we wanted. The soap needed to be mixed well so the fats and oils balance out with the sodium hydroxide. After our mixture was thick enough we added our lemon oil for scent and green coloring. We poured the soap into paper cups that we used as molds and allowed them to sit for about two weeks to become the solid bar soap we intended it to be.
After making and testing both of our soaps me and my agreed that they both worked about equally the same. The bar soap we made did seem to have a deeper clean than the bar soap, probably because of the lye solution used. The bar soap and the liquid soap were definitely similar in the aspect that they both used sodium hydroxide and oils to cleanse but the bar soap had more fats to make it solid .
The results of our experiment were really good, we saw what soap contains and how its made and got to do it first hand. We also learned that sodium hydroxide was the cleaning chemical used in soaps and the oils were to sooth the skin and hydrate it as well. Our soaps worked very well and cleaned very nicely.
I think our results were very desirable and we learned a lot . Us consistently working to gather our materials and keeping focused when we had them all helped us get a desirable product. I think I personally worked well during this project and remained focused. I also kept busy when we had down time with worksheets and another experiment.
For this project i worked with lily, she was really organized and reminded me constantly to get the materials. I think we did a good job on this project .
I were to do this project again I would try using different fats and oils and scents. I would also experiment with making it different colors. To make this project better I would change the molds we used and add more scent. If i were to organize another group I would not mind working with lily again but would also want to try working with new people. I personally would not want to continue this experiment.
Something I took away from this experiment was that I learned how different soaps are made and learned what is put in them to make them clean and smell well.
