In a mason jar or recycled soap dispenser, add the water first (to prevent bubbles) then the liquid castile soap, followed by the oils. Shake the ingredients together.
Shake the soap dispenser before using, then squirt a small amount on your hands as needed, rinsing with water.

Notes
You don't have to use the essential oils. You're welcome to skip the essential oils or experiment with other options (lemon, grapefruit, peppermint, etc.). The oil and vitamin E are added to moisturize the skin. You're welcome to skip these ingredients. Any oil will work: olive oil, avocado oil, skincare oils, etc. The oil won't blend with the water, so you'll need to gently shake the soap before use. Castile soap is a plant-based soap made from vegetable oils (olive, coconut, palm) and plant oils. There are several reasons why castile soap is awesome…
Super Versatile: You can make cleaning and body products with the same soap.
Inexpensive: A 32-ounce bottle of castile soap will cost $17. Yes, this is more expensive than a bottle of all-purpose cleaner, but it will last you for months! Castile soap is highly concentrated so a little bit goes a long way.
Non-Toxic: Castile soap is made with easy to recognize, simple, non-toxic ingredients. This is why you can use it on your skin and the surfaces in your home.
When you introduce water into a product without a preservative you always run the risk of introducing bacteria, so use water-based products quickly. If you don't have distilled water, use filtered water and use the soap quickly.
