Is it weight percentage or mole percentage in a formula that matters most?
I am trying to make a Shampoo formula from a patent.
The formula in patent has
Active surfactants
SLE3S 12.5%
SLS 1.5%
CAPB 1.5 %
As I don’t have SLE3S i want to use SLE2S instead of it.
I want my formula to be as close to that original as possible.
Now when i replace SLE3S by SLE2S, should i replace it by equal weight percentage and use 12.5% SLE2S or with equal mole percentage which is 11.19% SLE2S by weight?
Or should i ask, is it the weight percentage or mole percentage that matters most?
Molecular weight of SLE2S 376.4861
Molecular weight of SLE3S 420.54
