    When I worked on small batches, I always mixed the PQ7 with about the same amount of water or surfactant before adding it in my product.

    For production, we used to add it very slowly on one side af the tank (far from the mixing point) with rapid mixing and we never had any problems.

    Don’t know if this help.

    That’s good to know - thanks so much Ayla.
