The soap has a high pH number and can be harsh on the skin
Kirk's Castile Soap is a coconut-based product that has been in the market since 1839. The company offers a range of soaps, including an original fresh scent, a fragrance-free option, and a liquid soap. The soap is marketed as a natural, gentle, and safe product for the entire family. However, it is important to note that the soap has a high pH, which can be harsh on the skin.
The skin's pH, also known as the acid mantle, typically ranges from 4.5 to 5.5 and is slightly acidic. This acidic nature of the skin helps protect it by creating a barrier against irritants and harmful substances. However, when we use products with a higher pH, such as Kirk's Castile Soap, it can disrupt the skin's natural pH balance, leading to potential skin issues.
Studies have shown that using high-pH soaps can cause an increase in the skin's pH, resulting in a range of negative effects. These effects include an increase in dehydration, irritability, and alterations in the bacterial flora of the skin. In addition, high-pH soaps can interfere with the skin's ability to repair itself, leading to long-term damage and an increased risk of skin diseases.
The majority of soaps available on the market have a pH ranging from 9 to 10, which is significantly higher than the skin's natural pH. This includes Kirk's Castile Soap, which, due to its high pH, can be too harsh and drying for individuals with sensitive or dry skin. The high pH of the soap can strip the natural oils from the skin, leaving it feeling dry and tight.
To mitigate the potential harshness of Kirk's Castile Soap, it is recommended to moisturize the skin after use. Additionally, individuals with sensitive skin should opt for the fragrance-free option, as fragrances can further irritate the skin. It is important for consumers to be aware of the potential risks associated with high-pH soaps and make informed decisions when choosing personal care products.

It is also fragrance-free, which is ideal for those with sensitive skin or fragrance allergies.

However, some users have reported that the soap was harsh and drying on their skin, with one user with eczema stating that it did not work for them.
It is important to note that Castile soap has a very high pH, which can be too harsh for the delicate skin on the face. Some users have reported a burning sensation when using the soap on their face. Therefore, it is recommended to avoid using Kirk's Castile soap on the face, especially if you have sensitive skin.
