Quiz Answer Key and Fun Facts

1. Let's start at the beginning. What are the essential ingredients in soap?

Answer: Oils/Fats and an alkali

Soap is made when you combine solid and sometimes liquid fats (from vegetable or animal sources) with a strong alkali such as caustic soda (sodium hydroxide).

2. When mixing the caustic with distilled water, I add the water to the caustic.

Answer: False

The caustic is added gradually to the water, not vice versa. Heat is generated by this process.

3. When I add my caustic solution to my melted oil mix, what is the temperature at which both mixes should be?

Answer: Approximately 45 C

The mix needs to be at between 40 & 50 C. Any hotter and the chemical reaction will occur too fast; any cooler and the oil will not melt.

4. What sort of oil would I probably not use in my soap?

Answer: Engine oil

Canola, coconut, palm, olive and safflower oils are all suitable for soap making, as well as others such as almond, avocado and castor oil.
Engine oil would be unlikely to make a nice product.

5. OK, I have stirred the mixture to the desired point. Which of the following would I be unlikely to add now?

Answer: Charcoal

At this stage, you can add colour, fragrant or essential oils, flower petals etc.
In my first batch, I added wheatgerm to a pale green colouring, which gave an interesting texture to the soap.

6. My soap is now ready to pour. What should I not use as a mould?

Answer: Anything aluminium

Aluminium should not be used anywhere in the soap making process, as the caustic may destroy it.

7. My soap is now poured into the mould. What should I do next?

Answer: Wrap the mould in a towel to retain heat and continue the chemical process

I need to keep the mould wrapped for 24 hours after pouring to continue the chemical process active.

8. After about a week, I can remove the soap from the mould. If I have made a block in a milk carton, what should I do next?

Answer: Slice the soap into bars

Using a cheese slicer is a great way to cut your bar evenly.

9. After unmoulding the soap, how long should I leave it before using it?

Answer: About 3 - 4 weeks

The longer you leave the soap, the harder it will be. When my mother was given a cake of expensive soap, she always stored it in her undies drawer for at least 6 months. This not only made the undies smell nice, but the soap lasted much longer when she used it because of the extra time it was allowed to harden.

10. One item that is produced whilst making soap is usually removed from commercial soap, but is left in hand made soap. What is this ingredient?

Answer: Glycerin

In the commercial soapmaking process, glycerin is usually extracted and used in other products. In the handmade soap process the glycerin remains in the soap, making it more moisturing than a commercial soap.
