To make rebatched soap, first you will want to grate your soap base into a large bowl using a cheese grater. Make sure that you set aside a special grater just for making your soaps, as you wouldn’t want to use the same grater for your foods.
Once you have grated your base, measure your soap flakes and water, and add your flakes and water to your crock-pot or double boiler to melt.
Make sure that you use distilled water also when rebatching. Tap water can have minerals in it that will result in your soap not turning out properly. You can purchase distilled water the gallon for around a dollar at your local grocery store.
You need to make sure when you are cooking your rebatch soap that you use VERY LOW HEAT. If the heat is too high you will burn the soap resulting in it being ruined and burnt soap can also really stink up your kitchen.
Combine your soap and liquid in your pot and cook on a very low heat for 1 to 2 hours or until melted. Make sure you stir the mixture completely when you start cooking, and continuously scrape the soap off the sides of the pot. Then cover your mixture. You will need to stir it every 10 or 15 minutes to prevent burning.
Once the soap has melted completely then you can mix your scent, herbs, vitamin E, colorant etc. You want your soap to be about the consistency of bread dough when melted completely. If the mixture is too thick, add a little more liquid, if it seems to be too thin just cook a little longer.
Once your base is melted, then you will want to add your ingredients and mix thoroughly, then cook a while longer while stirring every 10 minutes until your soap is thick enough to mold by hand (don’t forget to scrape the sides again).
Let the mixture cool a bit before you mold it into soap balls, or press it into your molds. If making soap balls, just lay your balls on waxed paper until set, then cover it with more waxed paper and a clean towel and let it sit for 48 hours to harden.
If you used a soap mold, then freeze your soap before you un-mold, so that it will pop out of the mold easier.
Once your soap has set for 48 hours, it should be completely cool and fairly hard. You can use your soap immediately, or you can allow it to sit for several more weeks so that it becomes harder. The longer your soap sits, the more the liquid will evaporate from it, and the harder it will become.
Make sure your soap has cooled a lot before molding. Wear your heavy gloves to prevent burns.
Do not let your soap cook unattended. Do not let your soap cook overnight while you sleep. This could cause a fire and is extremely dangerous.
If children help you make your soap, make sure that you wash their hands very well afterwards. Some of the ingredients can be irritating to the skin if left on the skin for long periods of time, and can irritate the eyes if the eyes are rubbed while ingredients are still on the hands.
Before allowing others to use your soaps, or before selling, please test on a small area of your skin first. Also please test your soaps before allowing small children to use them.
Please follow all safety precautions that came with your crock-pot or double boiler.
Essential oils and fragrances need to be treated like you would any drug. Keep out of reach of children. As if ingested they can do serious harm. Some oils and fragrances can cause a rash if someone is allergic to them, so if you get some on your skin and find that you’re allergic, rinse the area well and make sure to wear gloves from then on when using that particular fragrant or oil.
Some essential oils are not intended for bath products, so before you order any make sure that they are safe for cosmetics.
Above all: PLEASE KEEP YOUR SOAP MAKING SUPPLIES OUT OF REACH OF CHILDREN AND FOR THE PROJECTS CHILDREN CAN HELP WITH MAKE SURE TO KEEP A WATCHFUL EYE ON THEM AT ALL TIMES.
