Castile Soap Liquid Base Biodegradable

Choose Size

This liquid soap base contains no surfactants or thickening agents and tends to have a runny consistency. It is ready to use as a liquid soap, hand soap & body wash. We do not recommend using 100% liquid soap on your hair due to the naturally high ph.

It is very mild, which makes it a great choice for those with sensitive skin. Some essential oils may not mix in perfectly with this all natural soap. We recommend mixing a small amount as a test batch prior to mixing up a large batch. You can add colour and fragrance to liquid Castile.

Safe for children and animals.

Great Ideas


Face: 2-3 drops on wet hands, applied to wet face

Body: one small squirt on a wet washcloth, applied to a wet body

Bath: Completely depends upon water amount, but roughly 2 Tbsp. soap in an average sized tub. (Doesn’t bubble, but still, cleans)

Shaving: Face – 10 drops; Underarms – 3 drops; Legs – ½ tsp; Work into a lather in wet hands and then apply to the area.

Teeth: 1 drop on a toothbrush. (Yes, it tastes like soap.)

Foot Bath: 1 ½ tsp. in a small tub of hot water.

Clearing Congestion: 1 Tbsp. in a bowl of steamy hot water. Breathe in mist with a towel draped over the head.

Household uses:

Dishes (hand washing): Pre-dilute 1:10 with water. Apply with a scrub brush and scrub dishes.

Laundry: 1/3-1/2 c. of soap for a large load in a normal washer. Add ½ c. vinegar to the rinse cycle. Use half of these amounts for front loader

Mopping: ½ c. of soap in 3 gallons (13.64 litres) of hot water

All-purpose cleaning: ¼ c. soap in a quart of water in a spray bottle. Add ¼ Tsp. tea tree essential oil if desired.

Windows: 1 Tbsp. soap in a quart of water in a spray bottle. Follow up with pure club soda, or half vinegar/ half water.

Toilet: Predilute 1:4 with water in a squirt bottle. Add ¼ Tsp. tea tree oil. Empty toilet, squirt bowl thoroughly, sprinkle baking soda on the brush, scrub bowl, let sit 10 minutes, turn the water on, flush.

Other Uses:

Fruit and Veggie Rinse: 1 dash (approx.. ¼ tsp.) in a bowl of water. Dunk produce and swish. Then rinse in clear water.

Dog washing: Amount varies widely depending on size, hair type and length, and overall dirtiness. I wet my dog thoroughly, then start to work in castile soap up and down their body until I have a good lather. Really massage it in down to the skin. Your dog will thank you for it.

Plant spray for bugs: 1 Tbsp. in a quart of water. Add ½ Tsp. cayenne pepper or cinnamon, if desired.

Ant spray (not on plants): ¼ c. tea tree soap in a quart of water. (This concentration will burn plants)

Castile is my GO TO Soap

This such a great soap base. I'm not horribly inventive but have found some great recipes using this soap and I continues to find new uses.

I was just thinking that very thing, Lori. Great for cosmetic and cleaning uses. Thanks for your great feedback!

I love the fact that I can get this product in different size containers.
Personally I use it in everything from basic cleaning products to insecticidal plant mixtures. Works perfectly.
