  • How to reduce viscosity of this detergent liquid?

    Posted by RedPill on January 7, 2020 at 5:07 am

    My detergent formula contains sles, capb, aos all item nearly @ 10-20% I want to make very thin.  I have tried propylene glycol. I also found sodium toluene sulfonate can reduce viscosity, but not easily available. If there is any other substance which is easily available and does the job please comment.

    Depending where you are on the salt curve, NaCl could reduce viscosity. I’d imagine a silicone could too.

    @RedPill a lot of options can be done so i think the easiest as @Perry said adding NaCl  but also adding AOS or by playing in pH you can do it . I think that  the best way is taking one kilograms of your product add gram by gram NaCl untill you reach the desired viscosity , then you will find the best level of NaCl  for you product , finally do correction to your batch refering to sample correction.

    Ethanol or isopropanol might help…

    Try introducing polysorbate 20 if it can fit the cost, or SCS/SXS if those are available.

    Reduce CAPB to begin with.

    But Sodium chloride is not so safe above 2 3 percent making your hair dry rough work outs.
    So keep in mind while adjusting .
    Reduce cocbetaine and add citric acid minor and add benzyl alchol works better for dissolving fatty acid .drops viscosity also. Mostly used from 0.5 to 1 percent maximum safe side.
