This product contains 2,4,D and Dicambra as well as Penoxsulam. Since 2,4,D and Dicambra eliminate White Dutch Clover quite well by themselves adding Penoxsulam really does little except add to the cost of a plant poison.
While by themselves research indicates none of these products are very harmful, in small doses, to our environment there is no research I have found that indicates what a mixture does.
