What is Castile soap? What are its uses and benefits?

Castile soap is a multi-purpose cleaner made from vegetable oils and contains no animal fats. Its composition makes it safe for cleaning the body and home. It comes in liquid and bar form and is vegan.

What is Castile soap?

Castile soap originated in the Mediterranean region, where many cultures made soap from olive oil and other vegetable oils. Its name comes from the Castile region of Spain, which was a center of soap making for centuries. Castile soap contains only vegetable oils – no animal fats – making it vegan, non-toxic, and biodegradable. The soap molecules found in Castile soap have one end that binds to water and another that repels it. When combined with water, the result is that one end binds to dirt, soot, and grease, removing them from the surface where they are applied. Due to the plant-based ingredients in Castile soap, it is non-corrosive and can be effectively used for cleaning the body, home, pets, repelling insects, and much more.

What is Castile soap made of?

Castile soap can be made with a variety of vegetable oils. Dr. Bronner's formula includes coconut, palm, olive, hemp, and jojoba oils, which provide a soothing and moisturizing feel. Other oils, such as avocado or walnut, can also be used.

Castile soap tends to be alkaline, like most other soaps (approximately on the same level as baking soda). However, it is far from being as alkaline as bleach, which means it is not corrosive to the skin or most surfaces.

Why does Castile soap have so many uses and other soaps don't?

Many people consider Castile soap a "true soap" due to its combination of natural oils and fats with a base, such as potassium hydroxide or sodium hydroxide. Because of its composition, Castile soap can be safely used for cleaning in various circumstances. In contrast, a significant amount of so-called "soaps" on the market are composed of synthetic ingredients, making them more like detergents than soap itself. Many synthetic cleaning products contain potentially harmful ingredients that can be toxic to you and your family, including:

Parabens;
- Phthalates;
- BPAs;
Triclosan.

These harmful substances are linked to cancer, infertility, and physical and psychological disorders. Furthermore, synthetic "soaps" are not easily biodegradable, making their use detrimental to the environment.
