Problem in Roll on
Hello experts I want to know the reason of what it happened to Roll on.
My first guess it is the bad storage but may it can others things.

Could you remove both Glyceryl laurate and your cellulose (HPMC)?

Actually for this lot it didn’t contain Piroctone Olamine, Glyceryl Laurate just sodium benzoate and texture will be worse also what I learned that viscosity enhancer improve stability not?
Why you want to delete Glyceryl Laurate and hpmc?

I’ve seen phase separation happening in emulsions with cellulosic thickeners, so ai recommend to make a test without it; in fact, I was checking similar formulas from Beiersdors and Unilever, and they don’t seem to have a thickener, since the film required for a roll-on is easily achievable through a proper mix of emulsifiers.

Is this your product? The ingredients on the label don’t match your ingredients list. Why are the ingredients listed by the the Trade Name on the label?
How was the sample stored? I have seen this sort of separation when samples are stored at elevated temperatures.

Yes you have right about ticket we correct it. The product was storaging by customer so I didn’t know exactly the conditions but my guess it was bad conditions actually the lot contains more then 6000 pieces and just less then 20 pieces lost stability….
