  • Formulating a cleansing gel +allergic reaction on the cheek

    Posted by Ghita37 on April 13, 2023 at 7:24 am

    Hi everyone.

    I formulated an extra rich cleansing gel that i have been testing for the past week twice a week and today to my surprise i saw like an allergic reaction/ like some kind of pigmentation on my face after using it

    Here are the ingredients i have used

    Aqua, Cocamidopropyl Betaine, Sodium Laureth Sulfate, Coco-Glucoside, Glycerin, Glyceryl Oleate, Polyquaternium-7, PEG-7 Glyceryl Cocoate, PEG-40 Hydrogenated Castor Oil, PEG/PPG-120/10 Trimethylolpropane Trioleate, Saccharide Isomerate, Propylene Glycol, Phenoxyethanol, Polyglyceryl-2 Dipolyhydroxystearate, Sodium Citrate, Disodium EDTA, Citric Acid, CI 42090.

    Can someone please tell me which of these ingredients might be the culprit?Also is it possible for a product to cause an allergy after two weeks and not before?

    Thanks a lot for your feedback

    How many time had you used it in two weeks?

    What is the pH and how much phenoxyethanol is there?

    It might be contaminated.
