    Hi, as I’m not familiar with the ingredients used, I’ve asked ChatGPT:

    Electrolyte Sensitivity of the Polymer

    Polymulse (Acrylates/C10-30 Alkyl Acrylate Crosspolymer) is sensitive to cationic surfactants like Quaternium-18. These can interfere with polymer hydration and gel network formation, leading to clumping or precipitation.

    Order of Addition

    These polymers must be fully dispersed and neutralized before introducing surfactants, oils, or actives—especially cationics or anything with cloud point behavior (like trideceth-6/12).

    pH and Neutralization

    While you’re keeping the final pH at 5.5, it’s crucial to neutralize the polymer at the right time and pH range (6–7) before adding other materials. If neutralization occurs in the presence of Silsoft, hydration fails.
