    Good evening to everyone
    I have a question to ask you.
    I formulated body creams based on cetaeryl glucoside, cetearyl alcohol and glyceryl stearate, thickened with polymer.
    As a preservative system I used phenoxyethanol and ethylhexylglycerin.
    the percentage of perfume is around 2%. After a few months, however, the emulsion loses consistency and becomes fluid.
    what may be due to the high percentage of perfume?
    what stability protocols usually follow for accelerated aging?
    thank you so much

    Yes, it could be due to the perfume.

    Thanks Perry, I read the very interesting link related stabilty protocols.Therefore, of each prototype I take 3 samples and place one at 40C, one at RT and one at 4C.Keep then for 3 months monitoring every 2 weeks.Is correct?
    And thermal cycles how is it better to set them?
    If my client want to keeo high quantity of perfume how can I stabilize the emulsion?
    Thank you very much
