How do I make soap from lye and vegetable oil?

There must be some kind of easy little recipe right?





Like add the lye first to some water or something like that?How do I make soap from lye and vegetable oil?
That's a start but soap making requires a fair amount of research before you begin mixing up a batch.





Generally it goes like this:





1. Weigh out your liquid and lye. Add the lye to the water and stir until combined.





2. Weigh out the oils, place in a stainless steel pot and melt.





3. When the oils reach about 90 - 95 degrees F. and the lye cools to about the same temperature they can be combined.





4. Pour the lye solution slowly into the oils and stir with a whisk to combine.





5. When the mixture become thick and opaque, it will be ready to mold. This thickening is called tracing and can be anywhere from 5 minutes to days depending on your ingredients.





6. Once the mixture is traced, pour it into the mold and cover with a blanket.





7. Leave it to rest for the next 24 hours. It will heat up and then cool down. Once it is cool, you can unmold the soap.





8. Cut the soap into bars and let the bars cure for 4 to 6 weeks. Until the cure time is over, the soap will be very harsh. The longer you let the soap cure, the gentler the soap will be.





These instructions should not be used to make soap but are just a general description of the process.





The following web site has recipes and step-by-step soap making instructions as well as information about the equipment and supplies you need to make soap successfully.

Have fun and good luck.How do I make soap from lye and vegetable oil?
Soap is basically a non-polar fatty acid with a polar cation (like Na+) on the ionizable oxygen on the fatty acid. The reaction folllows this equation:


Acid(Fatty Acid) + Strong Base --%26gt; Salt(Soap) + water


For example a reaction producing soap from stearic acid and sodium hydroxide is:


C17H35COOH(s) + NaOH(aq)--%26gt; C17H35COONa(aq) +H2O
You need to boil the vegetable oil with the lye. No water. Be careful of the lye and the hot oil. 90oC is not the correct temperature. Oil will not boil at that temp. The soap will clump at the top and can be skimmed off.
