    @bayo1214 Did you check pH drift in your product? Usually when you neutralize LABSA with NaOH, there’s an equilibrium formed rather than a complete neutralization, and unless you’re high on pH (over 10), the pH will go down affectin dyes (that are usually pH sensitive). This is for the color issue.

    Regarding separation, maybe you’re too high on LABSA, or actually, too low on pH so that your sulfonate is converting again into its acid form (LABSA), which is not as soluble in water as the salt.
