Castile soap is traditionally made with a base of olive oil and water and comes from Castile region of Spain.
Although olive oil is the traditional base oil, the soap can be made with coconut, hemp, avocado, almond, walnut, and many other vegetable oils.
Here’s why you should always opt for the ‘real deal’ castile variety:
7 Reasons To Start Using Castile Soap
1. Natural and Free of Toxins
Most of the soaps we purchase today contain a myriad of toxic chemicals which wreak havoc on our health.
According to Dr. Mercola, putting chemicals on the skin may actually be worse than eating them! That’s because chemicals on the skin are absorbed into the bloodstream without any of the filtering that would happen if the toxins went through the digestive system. With unprecedented levels of exposure to such toxins, we don’t yet know the cumulative effects of long-term use.
Castile soap contains only vegetable-based ingredients such as coconut oil, olive oil, hemp oil and jojoba oil, along with water and essential oils.
Be aware that the term ‘castile’ is often used loosely so purchase from a reputable brand or check labels closely for chemical additives.
2. Often Organic, Vegan and Fair Trade
In terms of the quality of their ingredients and their ethical and environmental impact, castile soaps are generally far superior to their conventional counterparts in terms of the quality of their ingredients and their ethical and environmental impact.
As they are based on vegetable oils – as opposed to animal (tallow) fat-based soaps – pure castile soaps are suitable for vegans, although before purchasing you should always check the label.
The most popular brand on the market, Dr. Bronner’s, offers a certified vegan and cruelty-free liquid and solid castile soap. In addition, most of the ingredients are certified organic and GMO free, and have been sourced using Fair Trade principles.
3. Doesn’t Encourage Super Bacteria
Shockingly, liquid soaps which are marked as ‘anti-bacterial’ may actually encourage hard-to-kill super bugs. Many of them contain a synthetic antibacterial ingredient called triclosan – a chemical registered as a pesticide with the EPA.
In addition to animal studies showing that triclosan contributes to antibiotic resistant bacteria, it may also alter hormone regulation, interfere with fetal development in pregnant women, and cause allergies, weight gain, inflammatory responses and thyroid dysfunction.
Even the FDA has stated that ‘there is currently no evidence that antibacterial soaps are any more effective at preventing illness than washing with plain soap and water’!
It looks like it’s best to stick with castile soap to keep your hands and home clean and germ free.
4. Lathers Easily
Many natural soaps don’t lather wellm, and thus making for a decidedly bubble-free bubble bath. This is because these products usually shun the use of Sodium Lauryl Sulfate (SLS), a chemical whose primary function is to foam up.
In the PubMed science library, there are nearly 16,000 studies relating to the toxicity of SLS. Animals exposed to this common soap ingredient – found in 90% of personal care products – experience eye damage, depression, labored breathing, diarrhea, severe skin irritation and even death.
Namely, castile soap can produce a high-foaming lather without the health risks, thanks to its rich oil content. The potassium hydroxide converts the vegetable oils into soap and glycerin, meaning you’ll require less water for a lather than with traditional liquid soap. Castile soap will also foam up in either hard or soft water.
5. Safe for Babies and Pets
Natural castile soaps without the addition of essential oils are exceptionally mild and safe for babies, due to their natural ingredients and chemical-free formulation, although you should know that they should be kept away from the eye area as they are not ‘tear-free’. (Most tear-free formulations use a synthetic numbing agent – yet another chemical additive).
Both dogs and cats can also be washed in many of these unscented varieties which won’t irritate their skin or build up on their coats.
Note: Always read the label before using castile soap on your pets, as the most essential oils can be toxic to cats.
6. Environmentally Friendly
Castile soap is gentle on you and the environment because it’s free of artificial foaming agents, harsh cleansers, deconstructed fatty acids from vegetable oils or fats (aka oleochemicals), petrochemicals and/or chemical anti-bacterial agents.
It’s also biodegradable.

A Note on Using Castile Soap and Vinegar
Castile soap is amazing for most cleansing needs; however, it’s only effective if you know how to use it correctly – and that means avoiding mixing it with vinegar.
In great part it’s due to the fact that vinegar is an acid and the castile soap is a base. They will directly react with each other and cancel each other out. So, instead of getting the best of both you’ll be getting the worst of something entirely new. The vinegar “unsaponifies” the soap, by which I mean that the vinegar takes the soap and reduces it back out to its original oils. So you end up with an oily, curdled, whitish mess. And this would be all over whatever it was you were trying to clean – your laundry or counters or dishes or whatever.
