What is TFM?

TFM or the Total Fatty Matter is one of the most important parameters that determine the quality of soaps. TFM refers to the total amount of fatty matter that separates out of the soap sample when mineral acid like hydrochloric acid is used. The fatty amount in soaps generally comes from fatty acids like palmitic acid, stearic acid, oleic acid, and sodium oleate which causes the TFM levels of the soap to be around 92.8%. Now, the small and medium-sized factories have started using soap tablets for manufacturing soaps which brings down the TFM value to 78% having 14% moisture. If fillers and preservatives are added to the soap, the TFM value can drop down to 50% as well.

The total fatty matter in soap is the key ingredient determining the quality of the soaps. The higher the TFM value, the less harmful it is to your skin. The inference drawn from TFM are:

  • A higher value of TFM indicates that the soap is highly hydrating, therefore would not cause any dryness to your skin. Such soaps are considered to be the least harmful to your skin.
  • A lower value of TFM indicates that the soap may cause damage to your skin. Such soaps extract all the moisture present in your skin, making your skin feel dry. Skin dryness leads to sensitivity that can ultimately cause skin infections, breakdown, and rashes.
