    I am making LGN lotion emulsion with GMS, cetearyl alcohol and sodium lauryl sulfate as emulsifiers. <div>

    It has 0.322% active SLS in formula and pH of Product is 5. It has 0.2% xanthan gum as stabilizer. The Product is stable in freeze thaw and 45°c.

    I saw somewhere in a supplier data that SLS is stable above pH 6.

    My question is: what the lowest pH at which SLS and SLES are completely stable?
