Milton Fluid is made of an aqueous solution of sodium hypochlorite and 16.5% sodium chloride. The Milton Fluid that is available to buy is a strength of 2% sodium hypochlorite.
Yes. The purification process during the manufacture of Milton ensures complete removal of all heavy metal ions, which would normally act as a catalyst to chemically break down many hypochlorites, causing instability. Therefore accurate levels of available chlorine can be obtained with Milton Sterilising Fluid.
No. As stated above, toxicity in hypochlorites is due to the by-product of their decomposition, sodium chlorate. With the heavy ions removed Milton decomposes into water and a small amount of sodium chloride (salt).
