  • Q

    We blended SOFTAZOLINE CPB into a shampoo formula. However, the shampoo turned cloudy. How do we make it a transparent shampoo.

    • A

      Cationic polymer with sodium chloride in SOFTAZOLINE CPB form some complex. Then, the shampoo is cloudy due to the effect of the complex. In such a case, we recommend SOFTAZOLINE CPB-R is desalination types.

  • Q
