Recipe and tutorial to make a natural melt and pour (glycerin) soap base with home ingredients: coconut oil, sunflower oil, vegetable glycerin, etilic alcohol and sugar syrup! Gather these ingredients and transform them into glycerin soap!

You already know by now that melt and pour soap can be made with a pre-made soap base that you can purchase (see this post if you don’t). These are nothing more, nothing less than glycerin soap bars.

You can easily make these soap bars yourself at home!! This is what this post is all about: teaching you how to make a “melt and pour” glycerin soap base from scratch.

There are some good reasons why you should try to make your own soap base:

  1. You can say: “I’ve made it”. There’s nothing like knowing and acknowledging before others that you’ve made the pretty glycerin soap in the bathroom all by yourself. From scratch! It’s a matter of personal realization and satisfaction.
  2. You control the ingredients. You want to avoid synthetic chemicals or allergens? Don’t use them. Petroleum or animal-based products? Don’t add them to your base. Just find out the recipe that best fits your needs. Besides, you don’t need a soap base that lasts 5 years, foams like a foam party, or keeps the scent everywhere you go… right? That is called commercial soaps and they may be harmful to your health…
  3. It can be more economical than purchasing the base itself. Ok, soap bases manufacturers have it all optimized for maximum profit, and you are wondering if you can actually make it cheaper at home. It all comes down to how much the ingredients cost in your local area. For me, in Portugal, soap bases cost from 8€/kg to 10€/kg. As I source an affordable coconut oil and vegetable glycerin and the rest of the ingredients are cheap in supermarkets, I managed to make it by a materials cost of 4,7€. Quite cool, huh?

This recipe and tutorial are from Silvana Liviero, a brazilian cosmetologist who was kind enough to allow me to publish her recipe on my blog. She manages a facebook group called saboaria artesanal para iniciantes , where she guides beginners in soap making with tips, answering questions and doubts, and sharing lots of cosmetic recipes (not just soaps). She also owns a YouTube channel.

This recipe uses coconut and sunflower oil, making it a conditioning and foamy glycerin base (without the usage of synthetic lauryl). All other ingredients are natural and, apart from the vegetable glycerin and lye, you should have them already at home.

Method Melt and Pour Soap Base


  • 3 Pitchers or cups
  • Heat resistant bowl
  • Digital scale
  • Spatula and whisker
  • Large soap mold


Lye Water

  • 67 g lye (100% sodium hydroxide)
  • 123 g distilled water
  • 200 g alcohol (ethanol)


  • 300 g refined or organic coconut oil
  • 100 g sunflower oil

Other Ingredients

  • 100 g vegetable glycerin
  • 120 g sugar syrup

Sugar Syrup

  • 110 g white sugar
  • 40 g water


Get Ready!

  • Wear goggles, gloves and mask! Look at “Safety Recommendations” in the video above or in How to Make Soap From Scratch
  • Assemble everything: ingredients, equipment, safety equipment. Prepare your workstation, including a well ventilated area to make the lye water. Measure all the ingredients. Don’t start the recipe without having everything ready!
  • Learn how to make sugar syrup in this video, but make sure you use the quantities indicated above: 110 g of sugar and 40 g of water. Do not let it turn into caramel – keep it thin.

Heat the Oils

  • Heat the oils until the coconut oil is fully melted. You will benefit from heating the oils up to 65ºC but it is not mandatory

Make the Lye Water

Make the Soap

  • Add the alcohol to the lye water and mix well
  • Pour the lye water with alcohol into the oils. Mix well for around ten minutes. The mixture will start to create a bit of foam, and then will make a small "parafin-like" film at the surface
  • Add the glycerin and the sugar syrup and continue to mix well
  • By now your soap should look like in the picture or in the video (3:41)

Molding and Curing

  • Pour the soap into your mold. Your mold can be pretty much anything, but I've used a silicone cake mold. Sprinkle with alcohol to remove any bubbles.
  • Let your soap set for 24 h, preferably in the fridge. It might take longer than 24 h to fully solidify outside the fridge.
  • Let it cure for 15 days, to dry out the alcohol and water.
