This project explores the saponification process involved in soap making. By combining oils with a lye solution, discover how chemical reactions create soap, illustrating chemistry in action.
The type of oil used will affect the texture and hardness of the final soap product.

Gather all materials and wear safety equipment.
Measure the lye and water separately, then mix them carefully in a well-ventilated area.
Allow the lye solution to cool to room temperature.
Measure the oils and heat them slightly if necessary.
Combine the lye solution with the oils and mix until trace is achieved.
Pour the mixture into soap molds.
Cover the molds and let them sit for 24-48 hours.
Remove the soap from molds and allow curing for 4-6 weeks.
The soap should harden and develop distinct properties based on the oils used. This will demonstrate the impact of different fats in the saponification process.

Use gloves and goggles when handling lye, as it is caustic. Work in a well-ventilated area to avoid inhaling fumes.
Show before and after images of your soap.
Include samples of different soaps made.
Explain the chemical reaction with diagrams.
Be prepared to discuss safety precautions taken.
Engage your audience with questions about soap chemistry.
Saponification is the chemical reaction that occurs when fats or oils react with an alkali to produce soap.
Yes, you can add essential oils or fragrances, but do so after achieving trace.
Lye can cause chemical burns, so it's essential to handle it with care and wear protective gear.
