All Natural Castile Liquid Soap Base - This old world castile soap base is exclusively made from olive oil and is known for its gentle cleansing and light lather. This soap is also suitable for babies and those with sensitive skin. Use it as is or thicken it up with a simple table salt water solution.

Special Tip:  You can also use .5 oz. table salt (very important it be plain table salt, just the cheap stuff) dissolved in 1.5 oz. distilled (warm) water to naturally thicken the soap prior to adding fragrance. We use about 12 ml of the salt solution in 16 oz. to get a very thick soap. Give it a try!

Nice soap, but smells bad...
Brambleberry has consistently provided good products, but this liquid soap smells like rancid olive oil. I bought this to use in my emulsified scrub. The yucky smell completely overpowered the essential oils. Plus, after rinsing hands clean, my skin smelled like rancid oil. Bummer.

Hi Melissa! I'm sorry you were disappointed in this base. I can assure you that it is not rancid! While castile soaps do have a distinctive smell because of all that olive oil we found it was easily covered by fragrance or essential oils.

I am thinking about selling this base, how would you go about labeling it? Does it fall under the Soap label?

Terah from Bramble Berry replies...
Hi Maria! For liquid soap you would generally follow the rules as you would for Cold Process soap. You can see how to do that in our How to Label Cold Process Soap blog post. There are 2 ways to label your soap, one is the final soap, which is the saponfied, unsaponfied oils and any additives. This is what we chose to use for our liquid soap. This means that you could label yours just as ours is on the product page, with the addition to any color or fragrance you use!

Interesting but.......
Great products always. Just wondering if I can make "Goat Milk Liquid Soap" from this base?

Reply from Bramble Berry
Hi Sarah!  I would not recommend adding goat milk to our Natural Castile Liquid Soap Base.  Normally when making a goat milk soap it would be part of the saponification process, rather than being added after the soap is made.  Adding goat milk to a soap base or paste would be like adding the milk to a partially made soap. It would most likely go rancid in your product.  I will email you personally to discuss this further!

great basic liquid soap
I use this in my handpumps in the guest bathroom and kid's bathroom. I make CP soap, but since my kids are little, it's much easier for them to use this to wash their hands than a bar of soap. Wish it came with castor oil in it, but castille is great too. I've thickened it with extra glycerin and the salt-water solution. Although it's not mentioned in the directions, the salt water will incorporate better if you also warm the soap otherwise, you can shake the salt water & soap mixture to incorporate it. Also, it doesn't work well with citrus EO's since citrus dissolves oils, it basically dissolves the soap. If you are adding eucalyptus EO, don't thicken it with the salt water solution since eucalyptus will naturally thicken it on it's own. Don't really care for the scent of the soap, but it's easy to cover with EO's.
