I would suggest you not mix things, especially when you're dealing with CS products which contain ions.
Things you add to a pure colloidal medium may cause the silver colloidals to bind to that product, in effect neutralizing the silver ions, possibly diluting the quantity of CS that would otherwise be available for the intended use.
If there is another product you wish to use, I'd simply suggest you wait for a few minutes to a few hours after using the CS.
