The best choice between toilet soap and bathing bar comes down to quality and cleansing efficiency, and this is primarily determined by the Total Fatty Matter (TFM) content.
Understanding TFM in Soap
- What is TFM? TFM stands for Total Fatty Matter. It's the measure of the amount of fatty acids that contribute to the cleaning power of soap.
- Why is it important? Higher TFM indicates better quality soap because it means more fatty acids are available for effective cleansing. Lower TFM content generally leads to a harder soap that may not clean as efficiently.
Comparing Toilet Soap and Bathing Bars
| Feature | Toilet Soap | Bathing Bar |
|---|---|---|
| TFM Content | Generally high; often meets Grade I standards (76% TFM or above in many regions) | Typically lower; less than 50% TFM, often lower quality |
| Cleansing | High efficiency due to high TFM, removing dirt effectively | Less effective due to lower TFM, may not cleanse as thoroughly |
| Quality | Usually of higher quality due to higher TFM content | Often considered lower quality due to lower TFM content |
| Recommendation | Grade I toilet soap is recommended for best cleansing | Less effective for thorough cleansing. |
Reference Information
According to the information provided on September 16, 2024, bathing bars typically have a TFM value of less than 50%. The reference indicates that choosing Grade I toilet soap, which has a high TFM, is recommended for achieving better cleansing and quality.
Key Takeaway
- Prioritize TFM: Always check the TFM of a soap. Opt for higher TFM for better cleaning and overall quality.
- Look for Grade I: Specifically, look for the "Grade I" label on toilet soap, as it ensures high TFM content and superior cleaning effectiveness.
Therefore, while both can be used for cleaning, Grade I toilet soap is generally better than bathing bars due to its higher TFM and more effective cleansing properties.
