    November 27, 2024 at 3:51 pm in reply to: Stability of GMS SE in acidic ph

    I guess that gms se contains basically non ionic emulsifier which is glyceryl stearate and very low level of stearate soap the other ingredients are : Ppg15 Stearyl Ether, Isopropyl Myristate, Aluminum chlorohydrate, parfum, Phenoxyethanol, Sodium benzoate.

    I already made sample and it looks great: very smooth texture with ordinary viscosity.

    So my guess, scientifically even with low pH just the stearate will decompose to stearic acid and base then because the low level of soap in gms se the stability will be fine, not?

    Thanks a lot, for

    2) do you think it is ratio between cationic active surfactants and fatty alcohol not between level of use of cationic surfactants and fatty alcohol?

    Because it is not really clear.

    4) Thanks for sharing however in practise if I use 5% ceteareth I have to use 20% fatty alcohol? It will not too much fatty alcohol?

    Nice guess. Just I guess even not Neutralised the carbomer is anionc not?

    So if it in both case there is anionc and cationic charges.

    Awsome as always @chemicalmatt actually the colour is a combination between green and yellow. Is benzephenon-4 is a solution for other colours? And what about Benzyl salycilate?

    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….

    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?

    For sure you must search about pH compatibility and also ingredients compatibility then the answer almost you can’t.
