    EGMS is also used for pearlizing, you may be able to get opacity from the fatty alcohols you have currently but not pearl.

    Wonder at Na benzoate by itself as adequate preservative for a shampoo.

    Benzoate by itself is not a good preservative - esp. in a shampoo.

    Na benzoate is not enough.  You could add chloromethylisothiazolinone as do many of the major marketers.
