Cosmetics Formulation Development

Hello, I would like to introduce members Try mixing it and see if it works best.

In fact, if on the web there is a claim that PEG-30 Dipolyhydroxystearate can It can be used in Glycol in Oil formula. The company should have tested it first, right? Otherwise, it would not be possible to specify that. So why did you throw it in to try and mix it yourself? Does it mean that you haven't tested it from the supplier first?

Hello, depending on the case Sometimes performance tests cover all forms. Sometimes only partially tested Or sometimes there is no test at all.
