Learn how to customize melt and pour soap with various additives. This is your guide to melt and pour additives and what's safe and what isn't to add to your soap.
Melt and pour soap is a fun craft to make for yourself, for sale, or for gifts. It's inexpensive, especially compared to making cold process or hot process soap, and you don't have to use lye.
Lye can cause serious injuries if not used properly. I didn't use it or keep it in the house until my kids were older because I was worried about an accident or getting distracted.
Melt and pour soap, by contrast, is easy to make. You just need a microwave and a knife to cut the soap, and you can make a custom bar of soap in about 10 minutes. Older kids can even help with adult supervision.
With so many melt and pour additives, you can customize your bar of soap, too.
With traditional soap recipes, you have to be very careful about the amount of oils and other additives that you use or your soap may be a fail. You don't have to be nearly as careful about adding things to melt and pour soap.
But you can't add just anything to melt and pour because it can irritate your skin - and some natural herbs are even poisonous. After you've made a few tried and true recipes, you might want to start experimenting with different additives.
Here is a list of safe melt and pour additives. You'll want to make small batches the first time and test them to make sure they work well so you don't waste a lot of product.

WHAT IS MELT AND POUR SOAP?
Melt and pour soap is a premade soap base that is ready to use, or you can customize it. You can cut a chunk off of the block and use it right away if you want!
While it's a decent soap to use on its own, that's no fun. It's more fun to melt it and add things to it to make a pretty bar or a functional bar for a specific need. You can create a custom bar of soap by adding melt and pour additives.
Melt and pour soap, sometimes called glycerin soap, is made of fats, glycerin, and lye. The saponification process has already be done, so you don't have to add lye to make a true soap.
MELT AND POUR SOAP BASES
When you're shopping for a melt and pour base, you'll find several options. Here are some of the varieties that you may find:
- White melt and pour
- Clear melt and pour
- Shea butter melt and pour
- Suspension melt and pour
- Goat's milk melt and pour
- Oatmeal melt and pour
- Castile melt and pour
- Cocoa butter melt and pour
- Honey melt and pour
And more!
Which melt and pour base should you use? That just depends on what you want the bar of soap for. I generally just buy white and clear melt and pour soap. I get mine from Crafty Bubbles.
If you want to have a scrubbing bar, you might want a suspension base to suspend whatever you add for scrubbing. Castile or oatmeal would be good for a gentle bar.
I don't buy the shea butter, cocoa butter, or honey varieties because I can just add the ingredient myself.

HOW MUCH TO ADD TO MELT AND POUR SOAP
Generally, you should add a tablespoon of melt and pour additives for each pound of soap. You may need more or less for different recipes, so you will have to experiment. If you want to add two things, use a half of a tablespoon for each one. Adding too much can prevent your soap from setting up.
Other Tips
Do not add fresh fruits or vegetables to melt and pour base because the soap can become rancid. You also want to avoid using fruit powders because they can grow moldy.
Not everything that can be added to traditional soap can be used in melt and pour because of the risk of mold. Make sure that you don't add any melt and pour additives that aren't completely dried.
Avoid using large pieces of herbs or flowers because they can clog your drain and make an uncomfortable bar of soap.
