pH changed by Dimethicone?
Has anyone else had an issue with this? I can’t figure out why, but the only thing that changed was the lot of Xiameter PMX 200, 100cst and my pH in one batch is 5.1 and the other 5.6 which is much higher than trend.
Any information on this happening to others is greatly appreciated!

It’s not likely the dimethicone. What else is in your formula?
Did you use all the same raw materials (from the same lot)? -
personally, I wouldn’t call that a significant change; depending on the product, it’s quite possible to have that sort of variation from batch to batch, even when it’s been made in an identical fashion from the same lots each time

@Bill_Toge - great point!

You all were correct… We didn’t notice.. Our edta got switched from disodium to tetrasodium… crap.
