    Hi. What’s the pH of your product? Peróxido usually descompose faster the higher the pH. Just as a reference, a peroxide based stain remover has a pH of no more than 4.

    Yes, but that pH would compromise the stability of your peroxide.

    As for the viscosity, chances are you’re not using the right rheology modifiers, and the peroxide is attacking it. There are some grades made for oxidizing bases.

      Can HEC work? or XAnthan Gum or SOD. CMC? MArket product ingredients list shows carbomer.

    They might be using Carbopol 674 (https://www.ulprospector.com/es/la/Cleaners/Detail/11384/35242/Carbopol-674-Polymer). I don’t think gums you mentioned could resist an oxidizing agent.
