Here's the rest of my long post, lol!
5)Become familiar with a
lye calculator. I like soapcalc but there are other good ones as well. I can't stress this enough. Unless you love math and are a wiz at it, run all your recipes through a
lye calculator. Also become familiar with all the carrier oils you will be using as well as the properties they impart to your finished soap.
6) As others have mentioned, place a great importance on safety. Lye is caustic and can cause grave injury if handled improperly. Also, an improperly made soap could harm the person using it. Never give or sell a soap to somebody without thoroughly testing it and fully curing it.
7) If you plan to sell your soap, do not do so until you have quite a few batches under your belt and are completely comfortable with the process. If you do venture into sales make sure you are abreast of all federal, state, and local laws. You may think that the authorities won't waste their time with a small time soap maker who is producing from their home but a quick google search will tell you otherwise. Invest in liability insurance. This will protect you from lawsuits in the event that one of your products harms somebody. Low cost liability insurance can be obtained from the Handcrafted Soap & Cosmetics Guikd as part of the membership and is a great idea if you plan to sell.
8) when you are first starting keep it simple until you are comfortable with the process. Use basic recipes that only incorporate a few oils and no color of fragrance. Once you are comfortable with the process start experimenting with colors and scents.
9) Learn to make your own equipment whenever possible. Molds, soap cutters, and soap stamps can be quite costly. Soap making can be a very expensive hobby so anywhere you can save money is a blessing. This obviously doesn't apply to your digital scale. Splurge on that. I make my own molds from wood and silicone and make my own soap stamps from casting resin. I am always wanting to try new things so this saves me a ton of money in the long run.
10) Welcome to the addiction. All this info may seem daunting, and I'm sure there are quite a few things I've neglected to point out, but soap making, in its essence, is incredibly fun. Of course you want to observe proper safety protocol but above all enjoy yourself. There's something incredibly gratifying about making soap from scratch in very much the same way that people have been doing for thousands of years. And you'll never again have to buy a bar of crappy chemical-laden "soap" from the store. Have fun and welcome.
