Sodium Laureth Sulfate 70% Lot Differences
I had a question regarding SLES 70% Active and different lots giving widely different results in my final formulations (shampoos). While I know you would naturally see differences from different manufacturers of SLES, I’m seeing wide differences in final viscosity in finished formula between different lots of SLES from the same manufacturer? Is there a good way to control for this variance lot to lot and is it possible to build an Excel model based on COA Lot data to account for differences? My formulas are very basic shampoo formulations with SLES, Cocamidopropyl Betaine and NaCl thickened.
