Lemon Lime Soap

Why is homemade soap better?

I’m not going to preach that I know all about commercial soap because I don’t – but with most things in this world, homemade is pretty much always the better choice because we know what has gone into making that product.

These lemon lime soap bars are made with a goats milk base which is naturally high in vitamins and minerals and rich in butterfats making it a great moisturiser. Using homemade soap helps to ensure you are using ingredients that are as natural as possible on your body. Plus it’s a great hobby and fun to do!

Soap Making Supplies

To make these lemon and lime scented soaps you will need:

Lemon Lime soap making ingredients - bowls of lemon and lime zest, soap base, essential oil and mold.

Soap Making Tools

You will need a Pyrex measuring cup/jug or bowl to melt your soap base in, as well as a grater to remove the zest from the fresh lemons and limes used in these soap bars.

Additionally, you will need a silicone mold to shape your soap. This rectangular soap mold comes with a wooden box so that the bar holds its shape as it cools. It also has a wavy, and a straight edge scraper to cut the soap into bars.

A wooden stick is helpful for stirring the soap as it melts, and for mixing in other ingredients – a popsicle or lolly stick would work.

How do I make lemon lime soap?

Step 1: Zest fresh lemons and limes until you have half a tablespoon of each zest. Pat dry with a paper towel.

Step 2: Cut the soap base into 1-inch chunks and transfer to a glass measuring cup/jug or a bowl to melt in the microwave for 30 seconds (or according to the package instructions) and stir with a wooden stick.

If the soap isn’t completely melted, stir and put back in the microwave for 10-second increments, stirring each time.

Step 3: Add the lime zest, lemon zest, and lemon essential oil to the soap base, and mix well before pouring into the silicone mold. You can sprinkle over more citrus zest if you wish.

Mist spray with some rubbing alcohol to help disperse any air bubbles, then leave to set for 3-4 hours.

Step 4: Remove from mold and use a wavy edge scraper to cut into 2-inch bars. If you don’t have a scraper, use a large sharp knife instead.
