The water we use in our products come from 100m water well. We filter the water with reverse osmosis filter that are for home use. This system has three more filters before reverse osmosis. Because of these filters i think waste water from reverse osmosis may be cleaner and better suited for cosmetic use compared to unfiltered water.
Recently as our sales has increased we sometimes face shortage of filtered water.
So in such times if i have to use one of these two waters, which one is better to use in cosmetic products?
