WHAT IT IS . . . WHAT IT DOES Phytic Acid, the hexa phosphoric acid ester of inositol, is a relatively strong acid composed of twelve acidic hydrogen groups. Its proposed structural formula, shown above, indicates a wide range of applications in a number of dif ferent fields. Available for the first time in commercial quantities, Phytic Acid's indicated applica tions are: • Chelating or sequestering heavy metals. • Facilitating p l a t i n g , improving adhesion properties of metal for application of pro tective coatings. • Inhibits rusting, improves appearance of metal closures on glass-packed foods. • As a n excellent starting material for certain pharmaceutical derivatives. • It m a y be useful in detergent applications.
• In photographic emulsions, ; for low fogging qualities, yet increased sensitivity. • As an additive to various types of paints and coat ings to inhibit corrosion, imsitOL i m p r o v e color, p r o m o t e 1 j | better adhesion to metal ι. .__ ; I surfaces. Perhaps Phytic Acid will fit in with y o u r cur rent research plans.
