For many people, pH value is an important criterion when choosing a personal care product. Therefore, the question often arises: what is the pH value of Aleppo soap, and what does this value actually mean?
This article explains the pH value of traditional Aleppo soap and why this is quite normal for classic soaps.
What does the pH value mean?
The pH value describes whether a solution is acidic, neutral, or basic.
- pH 7 = neutral
- pH below 7 = acidic
- pH above 7 = alkaline
Classic bar soaps are produced through a saponification process and therefore generally have a basic pH value.

What is the pH value of Aleppo soap?
Traditional solid Aleppo soap typically has a pH value of about 8,5–9.
This slightly alkaline pH value is a typical characteristic of traditional, saponified bar soaps.
The pH value of Aleppo soap is therefore not a quality defect, but a natural property of classic soaps.
Why is Aleppo soap alkaline?
Aleppo soap is made by saponifying olive oil and laurel oil with water and sodium hydroxide.
During this traditional manufacturing process, the solid soap is produced, which then matures for several months.
The alkaline pH value is a natural consequence of this saponification process and is one of the typical properties of every classic bar soap.
Frequently asked questions
Is a pH value of 8,5–9 normal for traditional Aleppo bar soap?
Yes. A pH value of approximately 8,5–9 is typical for traditional, saponified Aleppo bar soaps. Slight variations may occur depending on the recipe, manufacturing process, and measurement method.
Does all Aleppo soap have the same pH value?
Slight variations may occur depending on the manufacturing process. However, traditional Aleppo soaps are generally alkaline.
Does a higher pH value mean better cleaning?
The pH value alone says nothing about the quality of a soap. Crucial factors include the recipe, the ingredients used, and the traditional manufacturing process.
Conclusion
Traditional solid Aleppo soap typically has a pH value of around 8,5–9, making it one of the classic alkaline natural soaps. This value results from the natural saponification process and is typical for handmade bar soaps.
Those who choose Aleppo soap receive a traditional natural product with a simple recipe of olive oil, laurel oil, water and sodium hydroxide, which has been used for daily cleaning for centuries.
