Faqs
Q: Is this a finished liquid soap?
A: Yes. It can be used as supplied or carefully customised for a particular application.
Q: Why does the lather differ from a commercial shower gel?
A: It is made from saponified vegetable oils rather than a synthetic surfactant system.
Q: Can it be diluted with water?
A: Yes, but dilution changes the concentration and microbial stability. Prepare small quantities or use a properly preserved and tested formula.
Q: Can it be used for hair?
A: It can be used as a traditional soap-based cleanser, although its alkaline nature may not suit every hair type.

I use the Castile liquid soap as is and find it very moisturizing than most store bought hand washes.Will buy again
Love this as a soap free and fragrance free cleanser. I use it on my toddlers too.
Firstly, I loved how everything was packaged. I got a few other things and everything was packed with paper to secure it and because we love Gaia, I reused the papers to make sewing patterns, so thank you for that.
Now the soap, I love it.i use it for a lot of things, and the 5l lasts me a few months so it’s great deal for your money
If you are looking for a good, natural soap base- this is it!
I would definitely recommend this to anyone looking for a safe and natural alternative to commercial products.
Made some shampoo with it and it worked amazing for my formula. Will make some soap for my kids with it
I've been embarking on a project every month in making my own beauty & personal products to get rid of as many harmful chemicals as possible. This month is shower gel & shampoo. The shower gel has worked so well - I can't go back to the commercial stuff! the shampoo is still a work in progress... Thank you to Essentially Natural for an amazing range of products as well as a wealth of information on your website to help in making your own products.
This soup is the answer to sensitive and aging skin. The effect of the soup after use is a silky soft and moist skin. I am thrilled that I made the switch to this product and a little goes a long way.
Love how soft this makes my hair. I made the essential natural recipe to create my shampoo. I'm looking forward to trying out new recipes like a face wash.
The best soap I've ever used so far. It just works for everything and it's very friendly on the skin.
I'd recommend it for everyday use. I'm never going to stop using it. I might as well get myself more As soon as my 1.5l gets finished
I bought the pure Castile soap liquid, macadamia nut oil and rosewater to make my own face wash, using your recipe on the essential natural blog, and I've got such a surprise, wonderful products and wonderful recipe, leaves my face so smooth after every wash, Wil never use another face wash
Thanks

I love how many uses this product has - cannot wait to test it out.
I was expecting a gold thick liquid and I found this to be light in colour. I wanted to make baby body wash with it and I am struggling but the product itself is great on it’s own but I will keep trying. In fact I will try your shampoo formula and give feedback
Great product!!!!! Was searching high and low for a good quality Castile Soap and i found it!!!!!!!
Thank you for great product and great service!!!!!
This Castile liquid soap is perfect for making my own liquid hand soap which is free of parabens and petro chemicals.
I was born with an immensely sensitive skin and developed Eczema during my growing years. I have spent large sums of monies purchasing both bar and liquid soaps, some of which, intensified my skin problems!
In sheer desperation, I ordered the Essentially Natural Liquid Castile Soap Base.
Within 4 weeks after using the Essentially Natural Liquid Castile Soap Base, what a magical transformation took place!
I was overwhelmed with joy as my skin had started improving and within 6 weeks to date I no longer suffer from irritated, itchy, dry skin skin since using the Essentially Natural Liquid Castile Soap Base.
Decanting the Essentially Natural Liquid Castile Soap Base into Pump Bottles is so convenient, and, to which I add a few drops of my aromatic Essential Oils of choice!
Loved the products but môre the service
i run a small business called Cosmic Fairy .
i used this line to my own bubble bath and you wouldnt believe the results.
cant wait to make more bubbles to my range
I am in love with the product, although I wish I bought a bigger bottle. This product has allowed me to create body wash samples which already my customers are waiting for more.
I am honestly pleased with this platform as they have products to help boost small businesses
can liquid Castile soap be whipped ?
Hi Renika, I have only seen the castile soap bar be whipped up, not the liquid soap. But I think it may work if you also melt some butters in with it to give it some viscosity :)
It's my second time buying this soap and I love it. It's very gentle for my face and doesn't give me any breakouts or leave the skin feeling dry.
Happy with product and service
it works well on the hair, not so much for the face.
Absolutely love this gentle soap!
I love how gentle this castile soap is compared to others. Absolute fave!
Used to make liquid handwash and other household cleaning products
I absolutely love this soap, I use it in my DIY facial cleanser recipe, and it does not dry my skin out like other castile soaps I have tried. I absolutely love, love, love it and will continue to use and but this brand.

Good product to make shampoo and body wash with. My hair adjusted to the pure castille readily and personally i much prefer to use nice, simple ingredients than the big list of things in shop toiletries. 5stars
I'm using this as a shampoo, and it's amaaazing. My hair isn't dry anymore, and feels soft and moisturised. I'll definitely be buying more.
Good product
This stuff works wonders, but I do not like the smell of it at all. Even after adding essential oils, I could not completely mask the strong soapy smell.
