Let us now see the difference between soap and detergent:
|The sodium salt of long-chain fatty acids makes up the soap.||Sodium salts of sulphonic acids make up the detergent.|
|\(-COO^-Na^+\) is the ionic part of the soap.||\(-SO_3^-Na^+\) is the ionic part of detergent.|
|Soap is manufactured from animal fats or vegetable oils.||Detergents are obtained from hydrocarbons extracted from crude oil.|
|The effectiveness of soap reduces in hard water.||Detergents are effective in hard water.|
|Soap forms a scum in hard water.||Detergents do not form scum in hard water.|
|Soap has a poor foaming capacity.||Detergents have a rich foaming capacity.|
|They are biodegradable.||They are mostly non-biodegradable.|
Have you ever noticed the term "TFM" mentioned on the soap cover?:
Total Fatty Matter (TFM):
The Bureau of Indian requirements stipulates that the total fatty rely (TFM) on in a bathing bar must be much less than \(60%\), however, not less than \(40%\), while that in a cleaning soap has to be over \(60%\) but less than \(76%\).
The TFM quantity describes the pleasantness of a soap. It provides moisturizing residences to the product, leaving your skin deeply cleansed but gentle and supple. Higher the TFM, the better the soap is.
