    Stearyl Alcohol would be my guess

    I’d guess either before or after the Cetyl Alcohol. Probably after. I highly doubt they have fragrance at a level above 1%

    I also vote Cetyl Alcohol is the line.

    @Perry44 @Paprik @richard thanks.

    So it may have more than 1% sodium xylenesulfonate. What would be the function if it in this formula?

    That formula I know almost by heart (why didn’t you ever want to hire me, P&G? hehehe). From the patents I’ve seen, they use Stearyl at 0.64% and Cetyl at 0.36%. Percentages could vary a bit, but in any case, I’d bet Stearyl is lower than 1%. For the SXS, keep in mind you have quite some electrolytes in that formula (your Na citrate-citric acid buffer, added NaCl, surfactant’s NaCl, Na benzoate, Na4 EDTA, etc.), so you need to prevent precipitation/solubility issues, and that’s where SXS comes in handy. They use a lot of it in their dishwashers as well.

      Can you mention the patent!

      I have seen two patents with 1% sodium citrate but non of them like this.

      By the way, does SXS suspend silicone too like EGDS does or no effect on that?
