Using two anionics in the same formula….Why?
As I was looking at INCI’s on incidecoder dot com the other day…I came across a brand that was pretty consistently using a pair of anionics as co-emulsifiers. They were using both SSG and GSC in the same formula, and based on INCI order, these were not even the primary emulsifier.
What is some of the logic, behind using a pair of anionics as co-emulsifiers.
I should state…I always use one or the other…but it had never occurred to me….to use both as a ‘co’.
Let me hear why you may have used two supporting anionics….in the same formula.
