Importance of water in liquid formulations

Water is the major constituent in most of the liquid formulations. Many formulators tend to forget this aspect and feel what harm can water do to the formulation. This is where the formulator is wrong. Water as such consists of various minerals depending upon the source. Many of these minerals tend to destabilize the liquid formulations. Minerals like calcium, magnesium, iron, other minerals in smaller quantities also tend to reduce the foaming action, we generally tend to add more surfactant to enhance the foaming in hard water, but actually if your water quality is good the surfactant levels can be reduced and there is a direct savings in the formulations. My suggestion is anyone seeking to manufacture liquid formulations must invest in a good reverse osmosis system and use only ro water to formulate the liquids. This gives a better product clarity, stable product, better viscosity and hence gives big savings and perfect formulation. Reverse osmosis machines have become more economical and hence is a must for any formulator.
