In conclusion we were successful in production of our companies soap. Our trials were mostly successful with minor failures, but with each failure brought us closer to our final product and as a group. We found that when producing the hard soap that we had to stir the mixture of melted Crisco with the lye water until the mixture turned a bright soft pink like a strawberry smoothie. Also that if more Crisco was added the more oily the soap became. When producing the 1 lb of the soap, we followed the recipe above that was made with our calculations. Then when producing the liquid soap we made 3 different samples. We found out that the more glycerin and less water we put the more thicker the soap became, but with more water and less glycerin the smell came out more. Altogether we found that our soap we produced was a success and that if the soap recipe above is replicated the soap produced will be efficient and will "Refresh your soul and cleanse your mind with Island Daze all the time!"

- When making liquid soap, hard solid bar soap must be made in order to make liquid soap. We first need to make the bar soap. We are going to use a basic soap recipe that produces 21g of unscented soap. Once produced we are going use stoichiometry and percent composition to figure out how much of each ingredient makes the soap and then convert those numbers using stoiciometry to find how much can make one pound of the hard soap with also keeping the percent composition the same of the basic recipe. Next when making the liquid soap we have to boil water and shred the bar soap, then add other oils and scents. We also have to add a certain chemical compound to keep the soap liquid and convert back to a solid, as for our hard base soap it started as a liquid but when energy energy is taken away from the soap it hardens.

Lab Apparatus Designs
- Beakers
- Balance Scale
- Graduated Cylinders
- Hot Plate
- Cheese Grater (one in mid condition you want to get rid of, suggestion after use to make soap: do not use to grate cheese)
- To make 1 pound of liquid soap
- Lye
- water
- Crisco
- Glycerin
- Assorted aroma oils
- 1 lb of Hard soap(unscented):
- Grab materials
- Tare scale with medium sized beaker
- Measure 55 g of lye
- Reset scale
- Tare scale with another medium sized scale
- Measure 77 g of water
- Tare scale again(beaker size depends on how much the mass scale can withstand.)
- Measure 317 g of Crisco in beaker(you might have to measure a certain amount of Crisco in a smaller beaker as the scale might not be able to handle that much mass and then put Crisco into a big beaker and then repeat but measure the difference needed.)
- Melt Crisco about 3/4
- Mix water and lye, lye to water not water to lye. Let lye water mixture cool to 85 degrees Celsius
- Melt Crisco completely
- Pour melted Crisco into another large beaker
- Pour lye water mixture into beaker with Crisco and mix until a soft pink color is established
- Let soap harden over night, if not harden within one night leave it for another night.
- After soap is hardened, it is turned into a liquid soap.
- 1 lb of liquid soap
- Measure 450 milliters of water
- Heat water on medium/high heat
- Tare beaker and measure 35 grams of hardened soap
- Use cheese grater to shred soap
- Put shredded soap into heated water and stir until no soap residue is floating in water.
- Measure 6 milliliters of glycerin.
- Pour and mix into the soap mixture.
- Pour 2-3 drops of each assorted aroma oil.
- Mix until foam starts to form on top.
- Remove mixture from heat and let mixture sit for 12 hours or overnight.
- After waiting give mixture a good mix, and let it sit for 3-4 hours.
- If scents are not strong enough to your liking feel free to add more, just be careful assorted oil aromas have a really strong smell in large amounts
