Maxophos-235(S7)
Introduction :-
Maxophos-235(S7) is an organophosphonate exhibiting excellent sequestration of metal ions at stoichiometric concentration and threshold inhibition of metal salt precipitation at sub-stoichiometric concentrations. The ability of Maxophos-235(S7) to disperse or de-flocculate solid particles and the temperature stability makes it a versatile ingredient for applications requiring efficient Iron control. Maxophos-235(S7) applied in scouring process to remove Iron & water hardness ions in order to achieve better fabric whiteness, prevention of staining due to Iron deposits and prevention of fabric damage during bleaching caused by embedded copper or Iron fragments.
