The other week I was made aware of a new ‘rule’ that’s making its way around the virtual hallways of cosmetic school (which one, who said what and why doesn’t matter), the rule being that you should not homogenise Carbomers. Now I’m not sure of the wider context of this truth or how it was originally meant to be taken but it was clear that in this case the statement had been taken as literal truth and that was causing a problem which I just couldn't help but investigate.
