How to Make Sudsy Liquid Soap

Sudsy liquid soap produces a lather that is attributed to the type and amount of oil you use in the recipe. Homemade liquid soap recipes that do not call for oils will not, however, become sudsy when washing hands, dishes or clothing with the soap.

1. Prepare the 8-ounce plastic bottle. Wash the inside and outside of the bottle with warm water so that the bottle is free from residue and any dirt that can contaminate the soap you are making inside of it.

2. Measure 2 tablespoons of liquid castile soap with a measuring spoon, and pour it into the plastic bottle. Liquid castile soap is a gentle and mild soap base that is often used as the foundation for other types of soaps. It can be purchased from organic or health stores, farmers markets and from online manufacturers.

3. Pour 1 1/2 cups of warm water into the bottle, followed by 3 teaspoons of vegetable glycerin. The warm water acts as a soluble agent and the vegetable glycerin gives the natural homemade soap its thick and slippery qualities.

4. Combine 2 tablespoons of coconut oil into the bottle. The coconut oil is what gives this homemade liquid soap recipe its sudsy nature. The more coconut oil you use, the more suds the liquid will form during use. You can add more tablespoons or less of the coconut oil, depending on your personal preference for lather. Additionally, olive oil can be substituted for coconut oil, but keep in mind that olive oil will produce a more oily residue on the skin after it is washed away.

5. Add 8 drops of an essential oil of your choice, such as lavender or rose, to give your homemade liquid soap a mild fragrance. Add more drops of the oil to make the scent stronger.

6. Secure the lid of the 8-ounce bottle and shake the bottle vigorously to combine all of the ingredients. Shake the bottle for 30 seconds and assess the soap to make sure it is well mixed. Test the soap out by pouring some into your hands and washing your hands in the sink with the soap. Adjust the recipe as you deem necessary.
