In a true superfatted soap, a portion of the fats remains untransformed into soap. The stated percentage informs the formulation, not a guarantee of comfort.
1. Understanding the principle
The recipe is designed to retain a portion of fats. This choice is distinct from the glycerin produced during manufacturing. The two terms do not refer to the same thing.
2. Distinguishing the methods
The manufacturer may reduce the calculated amount of lye or add fats depending on their process. The interpretation of the percentage depends on the method. Therefore, two stated figures are not always directly comparable.
3. Reading a rate with caution
A higher rate is not automatically preferable. It does not allow for ranking all soaps from most gentle to least gentle. The complete recipe and conditions of use matter.
4. Asking what the figure measures
If the percentage is important to you, ask the brand how it is calculated. The INCI list alone does not allow for reconstructing this calculation. Do not attribute an uncommunicated rate to a product.
5. Not to be confused with a skincare product
Superfatted soap is rinsed off. It does not automatically replace the skincare product applied after washing. If the skin feels tight after a shower, consult the guide to useful adjustments.
Key takeaway. Keep the meaning of the term in mind without buying based on the figure alone. The manufacturing stages explain the entire process.
