Is there some Zeolite (zeolite, man-made silicate) in the laundry ball you produced?
Washing balls inside our laundry ball, type A, type B and type C, and our stain stick absolutely dont contain Zeolite. But in order to enhance the dirt removing power of washing, the ceramic washing balls inside laundry ball type D, the first of our factory developed certainly contains Zeolite about 5g. We imitate type D laundry ball according to laundry ball made in other country. If you think its better to not use Zeolite according to the stipulation of environmental protection, we can fully change the formula of ceramic washing ball inside laundry ball, type D immediately. Not use Zeolite and not change the efficacy of the dirt removing power.
