    Hello Friends,
    I am trying to formulate acid thickener to thicken aqueous HCL solution wherein HCL concentration would be 15%. Purpose is to preapare an acidic toilet bowl cleaner. I am using the below formula to come up with a base thickener solution. Propylene glycol is used to disperse tallow amine ethoxylate when added to water or acidic solution
    Tallow amine ethoxylate 50%
    Propylene glycol 50% 
    When i add the above base thickener to aqeous HCL solution, it doesnt thicken it. I tried using Oleyl amine ethoxylate as well. Any suggestions on the formulae from your end please?

    Have you tried HEC?

    @amitvedakar: I am not inclined towards HEC or polymers to thicken acid solution. Looking for amine ethoxylate to use as i use the same material for other formulations and it will help me reduce inventory maintenance.

    Any suggestions from seniors in forum please.
    I tried using cetrimonium chloride and oleyl amine ethoxylate. But still no luck.

    @getmeraju not a senior, but I get a sense that the issue is the propylene glycol. I observed a thinning effect in a liquid detergent, and I remember reading somewhere that it usually reduces viscosity. Not sure in your system if this will be true. Have you used this same method to thicken other acidic solutions?

    @letsalcido is right avoid Propylene glycol. You get better result with Oleyl Amine Ethoxylate , Cetrimmonium Chloride, HCL (should be Fe free ie. Water white) & DM Water.

    You should remove PG in this formulation and you can use salt for dispersion
