I have read many times that unsaturated fatty acids have conditioning effect when used in soap.
The reason quoted for this conditioning effect is that they are less potent cleaner.
Now I wonder what makes them less potent cleaner, some say it is because they are less soluble in water.
So i ask why are they less soluble in water, then answer comes because they are big in size (fatty acid molecule size).
Well could be, but all soap molecules have hydrophilic (water loving) and hydrophobic (water hating) end.
So does fatty acid size have any impact of hydrophilic end to make it less soluble. Well I don't know.
If anyone can enlighten me with chemistry/core reason with may be some reference to reliable source please do. I am ready for some technical explanation.
Note: when i say unsaturated fatty acids I mean the ones which have converted to soap. The free oil in soap will definitely condition no question on that.
