What is Castile Soap?

Castile Soap is a natural liquid soap made from vegetable oils, named after the Spanish region of Castilla where it was first produced in Europe centuries ago. At a time when most soap was made from animal fats, Castile soap was an exception: made from olive oil and vegetable oils, mild and pure. The recipe has been preserved through the centuries and is still valued today for its simplicity and versatility.

Our Castile Soap is organically certified and made from saponified coconut oil and sunflower oil. A completely plant-based product, without animal fats and without palm oil. The soap is biodegradable.

What's in it?

Water, organic saponified sunflower oil, organic saponified coconut oil, glycerin, potassium citrate and citric acid. Nothing else. No synthetic surfactants such as SLS or SLES, no parabens, no phenoxyethanol, no PEG, no propylene glycol and no synthetic fragrances or colorants.

The glycerin in our Castile Soap is created naturally during the saponification process and is not removed from the final product, as is the case with many commercial soaps. This makes the soap gentle on the skin.

Benefits of Castile Soap

Versatile in use
One product for countless applications: hand soap, shower gel, shaving soap, dish soap, floor cleaner, laundry detergent and all-purpose cleaner. This means you need far fewer different products at home.

Gentle on the skin
Due to the vegetable oils and the naturally present glycerin, Castile Soap is gentle and suitable for virtually every skin type.

Completely natural and plant-based
No synthetic ingredients, no animal fats, no palm oil. Our Castile Soap is organically certified.

Biodegradable
Castile Soap is biodegradable and thus an environmentally friendly alternative to synthetic cleaning and care products.

Can be combined with essential oils
Customize the soap to your preference or purpose by adding essential oil.

How to use Castile Soap?

As hand soap
Dilute the soap with water in a ratio of 1 to 3 (for example 100 ml soap with 300 ml water) and pour into a pump or foam bottle. Add a few drops of lavender or tea tree for a nice scent.

As shower gel
Dilute in the same ratio as hand soap and optionally add a teaspoon of glycerin for extra hydration.

As dish soap
A teaspoon of Castile Soap in a wash basin with warm water is enough for hand washing. Optionally add a few drops of lemon oil for a fresh scent and extra degreasing action.

As all-purpose cleaner
Mix 3 tablespoons of Castile Soap with 500 ml water and optionally 10 drops of Tea Tree or lemon essential oil. Pour into a spray bottle for a simple natural all-purpose cleaner.

As laundry detergent
Use 50 to 100 ml of Castile Soap per wash, depending on water hardness and how dirty the laundry is. Do not combine with vinegar in the same wash cycle, as this will deactivate the soap.

Not recommended as shampoo

Although Castile Soap is often recommended online as a hair shampoo, we advise against it. The pH of Castile Soap is around 9 to 10, while hair and scalp need a much lower pH to stay in balance. When used on hair, the high pH causes the cuticles of the hair shaft to swell and open, resulting in dull, dry and frizzy hair. For washing your hair, it is therefore better to choose a real shampoo with a skin-friendly pH.

Tips for using Castile Soap

• Castile Soap is alkaline (pH around 9 to 10) and therefore does not react well with acidic ingredients or products such as lemon juice or vinegar. That combination makes the soap ineffective. Use them in separate steps or products.
• Always dilute before use. A higher concentration than necessary only wastes product and is not milder on the skin.
• Store in a well-sealed bottle at room temperature. Shelf life up to 12 months after opening.

Precautions

Castile Soap is a mild product and is generally well tolerated. If in doubt or with sensitive skin, test on a small area first. Avoid contact with eyes. Keep out of reach of children.
