How to Make Your Own Liquid Soap



  1. Add the soap flakes and the herb infused oil into a small saucepan with about ¾ cup of the water. Turn heat to low.
  2. Stir until the soap flakes start to dissolve into the water. This process may take some time.
  3. Add a little more water until you achieve the desired consistency. Handmade soap bars can differ in size so you may not need to use up all the water.
  4. Scoop off any foamy bubbles that start to form on the top.
  5. Once the soap flakes have fully dissolved, remove from the heat and add the essential oils if using. Let cool slightly. The mixture may thicken slightly but still remain a liquid. If it doesn't, return to the heat and add a dash more water and stir. If it's too liquid, add some more grated soap.
  6. Once cooled, pour your liquid soap into a soap dispenser.

How to Use

Shake gently before use. Use like any other liquid soap. Keep out of direct sunlight and use within 3-4 weeks. As this liquid soap recipe contains water, the use by date is relatively short. This recipe makes approximately 250ml. Tips:
  • For best results we recommend using a natural handmade soap bar rather than a soap that contains petrochemicals and synthetic ingredients. The Biome 100% true castile soap is the best option.
  • Infuse your fresh, clean and dry herbs in about 500ml of your favourite carrier oil. Then you can use what you need for this recipe and keep the remainder infusing until needed later.

As with all our DIY recipes, you can experiment to suit your preferences. Many factors can change the end result, including temperature, humidity, light, ingredient quality. Some DIYs can be amended by remelting or adding ingredients, but some cannot. Please read the whole recipe before beginning and remember to have fun!

Biome cannot issue a refund if the DIY skin care product, DIY hair care product or DIY body care product you make using our raw DIY ingredients do not perform as you'd hoped. We will, however, offer a refund if the raw DIY ingredient packaging is broken or leaking, or the ingredient itself appears to be ‘off'.

Before using any raw DIY ingredient for the first time, please first research that ingredient's potential benefits as well as safety precautions and possible side effects. Check with your medical professional if you have any concerns.

If you have severe acne, very sensitive skin, or another skin concern or health condition, we recommend seeking medical advice before using any new product on your skin, whether that be a raw ingredient, a DIY product you've made yourself, or commercially formulated product.

Please exercise caution when using essential oils. If you are pregnant or have any kind of health or skin condition, we recommend you speak to your doctor before use. Essential oils are highly concentrated liquids, so use in moderation. Pure essential oils should never be used directly on the skin and should never be ingested. When using an essential oil for the first time, do a skin patch test. Each essential oil is unique and may not be suited to everyone. Please research potential benefits as well as safety precautions before using any essential oil. Some essential oils may interfere with medication. Check with your medical professional if you have any concerns.
