Picture of Natural Soap Bars Without Breaking the Bank | Cold Pressed Soap

I have been wanting to make my own soapbars for a while, but found it quite daunting to start with. The recipes I found online used loads of different, expensive oils. And the fact that you use lye scared me too. But I decided to just give it a try. If you don't try, you will never know...

I wanted to make a soap that is not expensive to make. So I didn't want to go to the grocery store and buy five different expensive oils. I wanted to make a soap with inexpensive oils, or oils I had already lying around. So here you have it: how to make natural cold pressed soapbars without breaking the bank.

Step 1: Tools and Materials

Picture of Tools and Materials

To make the soapbars you will need to following:




  1. It's important to not use aluminium tools like bowls or mixing spoons. Aluminium will react to the lye, which you definitely don't want to happen.
  2. I started by using a paint mixer on a drill (see step 10) but definitely use a hand blender! It works waaaay better! (Trust me, I was mixing for a loooong time)
  3. Make the soap in a well ventilated area. The lye-water mixture will produce some gasses you don't want staying in your house.

Over time still kept the same aroma? Or is it getting weaker over time?
I tried another recipe, but the scent of lavender essential oil became imperceptible over the months.
What should I do to maintain the aroma?

2 tips:

1) If you don't have a silicon mold, use ANY container except a metal one, and line it with an inside-out plastic shopping bag. It'll have wrinkles but the soap will be usable. I've used cardboard boxes, plastic baskets, even glass pie plates! Do NOT use waxed paper. It will stick to your soap and the moisture from the batter will seep through to the mold.
2) Your essential oil won't be very noticeable in your cured soap unless you use an ounce or more per pound of oils. The exception to this are the mint and tea tree essential oils. These will be noticeable for a few weeks but they WILL fade over time. If you use a synthetic fragrance, make sure it's made for soap making or you might create an irritating soap or the fragrance oil won't mix properly in the soap batter.
If you want to learn more about making soap watch teaching videos like those at, and join a soaper's forum, like and ask questions.

This is an excellent ‘ible- I am going to try it cause I’ve always been afraid of lye too. But your directions seem like they will be easy to follow. Thank you ever so, and I voted for you!

1) Eso no es Lejía. Es sosa cáustica.

2) Lo que usa es una batidora, no una licuadora.

Thank you for your comment! The soap should be good to go after 24 - 48 hours. I made it more clear in my Instructable now, thank you for pointing it out. As said in the Instructable it's better to wait for 3 to 6 weeks, but after 24-48 hours it is safe to use the soap.
