Castile Soap for the Home & Body

Castile soap has been around for centuries and is considered one of the purest soaps on the market. It’s also cost-effective and perfect for tackling common skin issues like acne or eczema. Castile soap can be used in a variety of ways, from washing hands to bathing your face.

Castile soap is a type of soap made with vegetable oils, typically olive oil. It’s often used for washing the body and hair but can also be used in other ways like cooking or cleaning.


Are you looking for a soap that is manufactured with all-natural, chemical-free components that you can trust? Then, the use of castile soap should be prioritized. This soap is one of the most natural and biodegradable that can be made by hand.

Castile soap has a plethora of applications. It’s not only fantastic for washing your body and hair as part of a natural skincare regimen but it can also be used to clean laundry – and it’s safe for kids to use. In addition, because they are plant-based, Castile soaps are highly popular among vegans and vegetarians. It’s also available in liquid or bar form and doesn’t lose efficacy over time.

A research investigation found that using Castile to irrigate and finally wash polluted orthopedic wounds had a favorable effect in terms of potency. Normal saline, Castile soap, benzalkonium chloride, bacitracin, or sequential irrigation with all of the above were used to compare. When used in conjunction with progressive irrigation, Castile soap alone significantly reduced the risk of wound problems.

What Is Castile Soap?

Castile soaps have been around for a long time, and they were developed shortly after the famed Aleppo soap. Aleppo is a chemical-free, all-natural soap that combines oil from laurel (bay) trees with olive oil and soda. This is where the idea for Castile came from.

What is the composition of soap? In general, animal products such as tallow or lard are used to make soap. What precisely is Castile soap? It’s an oil-based soap available in bar or liquid form and doesn’t include any animal fats or synthetic components. Castile soap is regarded to be completely natural and non-toxic.

Castile soaps are made in the Castile area of Spain. While the original Aleppo soap recipe called for laurel oil, this was in poor supply, while olive oil was readily available in Castile. As a result, a pure white soap that was both gentle and effective was created. The whiteness was associated with purity, making it popular among the Spanish monarchy. Castile soaps started to spread over Europe as the years passed.

Castile is still one of the most popular European soaps in the current day. It has also become quite popular in the United States. Today, it’s widely available at health food shops and supermarkets. Castile soap may be produced using coconut, hemp, avocado, almond, or castor oils in addition to olive oil. All of these natural oils contribute to the soap’s hydrating characteristics.

Dr. Bronner’s Castile soap is perhaps the most well-known. Dr. Bronner’s parents started their profitable soap-making company in the basement of the Heilbronner house in Laupheim’s Jewish district. The Heilbronners invented the first Castile liquid soap in the 1880s, providing public washrooms throughout Germany.

As we know him today, he made his way to the United States, where he continued the family company, eventually forming Dr. Bronner in the 1940s. Dr. Bronner died in 1997, but his firm, Dr. Bronner’s, became the biggest personal care brand to be recognized under the USDA National Organic Program, with bar and liquid soaps certified by Oregon Tilth, a renowned certifier.

The Top 13 Castile Soap Applications

Castile soap may be used for a variety of purposes. For example, Castile soap may be used to wash your face, body, and hair, as well as to rinse produce, do laundry, and clean windows. Here are a few of my favorite Castile soap applications, as well as some ideas on how to make your products using this great soap.

For the Residence

1. Make Your Dish Soap

Castile soap is an excellent way to produce your own dish soap. There are no chemicals on your hands or dishes since it’s all-natural. Use Castile liquid soap for your typical store-bought dish soap, and a few drops will quickly clean your dirty plates.

2. Laundry Detergent Made at Home

What’s nice about using Castile soap to clean your clothing is that it won’t expose your garments to harsh chemicals, which means they’ll last longer.

You may also prevent skin irritation by eliminating additives like solid colors and fragrances, often included in store-bought versions.

3. Homemade Dishwasher Soap

You may use it to hand-wash dishes, but you can also manufacture your dishwasher soap with it. Try a citrus version, which not only smells great but has been proved to have anti-fungal properties against food-borne molds.

Shake together 8 ounces of Castile liquid soap, 1 cup water, 3 tablespoons lemon juice, and 10 drops of lemon essential oil to make your dishwashing soap.

To use, pour 1 tablespoon of the combination mentioned above into the dishwasher’s “open” section and 1 cup of white vinegar into the “closed” compartment. Add a bit of additional vinegar if your water is hard.

4. Homemade All-Purpose Cleaner

Fill a spray bottle halfway with white vinegar, then top it up with water. Finally, add a squirt of Castile liquid soap, a few drops of tea tree essential oil, and a few drops of citrus or lemon essential oil to finish. This combination creates a safe, natural, and effective home cleanser.

5. Homemade Glass Cleaner

In a spray bottle, combine half a cup white vinegar, 2 teaspoons Castile liquid soap, and 2 cups distilled warm water. Add a few drops of tea tree and lemon essential oil to the mixture to make it more effective. Please give it a thorough shake to combine everything and then spray it on your windows. Clean it with newspaper to keep it streak-free.

6. Homemade Tub Scrub

13 Castile liquid soap and 23% water in a spray bottle Spray the Castile mixture on top of the baking soda and let it sit for a few minutes. For a squeaky clean tub, use a scouring pad or scrub brush.

For the Human Body

7. Make Your Own Face Wash

Fill a foaming dispenser halfway with purified water and add 14 cups Castile liquid soap. Tea tree and frankincense essential oils, 5 drops each. Both oils are recognized for their antibacterial properties and their ability to treat acne.

8. Make Your Shampoo

It’s pretty simple to make your own Castile soap shampoo. Plus, you’ll be able to stay away from those pricy, unexpectedly poisonous shampoos (most of which are filled with chemicals that can cause lots of problems for your hair long-term).

Combine 7 tablespoons of Castile liquid soap, 6 teaspoons coconut milk, and 12 teaspoons coconut oil in a mixing bowl. This will result in around seven applications. It will keep for approximately a week in the fridge.

9. Make Your Own Hand Soap

34% boiling or distilled water with 14% Castile liquid soap in a foaming soap dispenser 5 drops of tea tree essential oil for antimicrobial capabilities and 5 drops of lavender essential oil for a beautiful and calming aroma

10. Castile for Shaving

Use around 10 drops for your face, 3 drops for your underarms, and 12 teaspoons for your legs. Work into a lather with damp hands before applying to the affected region.

If you want to add some moisture to your shave, you may add some olive oil to the mix.

11. Castile is good for your teeth

Would you imagine that one of the possible Castile soap advantages is natural teeth cleaning? That’s correct!

Brush as usual with a drop of Castile liquid soap, a decrease of peppermint essential oil, and a little dab of coconut oil on your toothbrush. Do not swallow, just as you would with toothpaste.

This is a fantastic method to benefit from the remarkable cleaning and disinfecting capabilities of Castile soap! (As a side note, although castile soaps are normally thought of as disinfectants rather than antibacterial agents, peppermint oil and tea tree oil both have natural antibacterial properties, so when these oils are added, the soap’s cleaning and bacteria-fighting qualities are enhanced!)

12. Foot Bath

In a small tub of hot water, dissolve around 1 teaspoon of Castile liquid soap and soak the feet for 10–20 minutes. Add a few drops of tea tree and lavender essential oils for extra benefits. Alternatively, you may use a Castile liquid soap that already contains these essential oils.

13. Congestion Elimination

Nasal congestion caused by the common cold or allergies may be relieved with a Castile liquid soap with essential oils such as eucalyptus or peppermint.

To make the liquid soap with essential oil, just put a few drops into a bowl of steaming hot water. Then, breathe in the mist while wearing a towel over your head. Of course, be cautious since steam might cause skin irritation.

Dangers and Precautions

A few words of caution:

  • It’s not suggested for color-treated hair since it may remove the color from the hair follicles.
  • It may be used as a shampoo on non-color-treated hair, but to prevent tangled or matted hair, it’s best to follow up with an acidic conditioning rinse containing natural acidic substances like lemon juice. Another option is to wash with Castile liquid soap and then apply diluted apple cider vinegar.
  • Castile soaps are considered bases; thus, mixing them with acids like vinegar or lemon juice is not suggested (because the resulting mixture will be a curdled solution that will leave behind a film rather than clean surfaces well).
  • When Castile liquid soap is coupled with hard water, a white film may be left behind on surfaces.
