  • Alpha Olefin Sulfonate - HIGH pH

    Posted by RedPill on September 9, 2020 at 6:47 am

    Hello,

    AOS (40% solution) I source from always having a very high pH grater than 11.

    > What should be the normal pH of AOS 40% liquid?

    Our preparation contains very less amount of water, so Its very hard to bring pH down to 7 with citric acid.

    Thank you.

    You have ask supplier if they have AOS preserved with alternative preservative rather than NaOH(pH Preservation), check with multiple suppliers
