Phytic acid: WHAT IT IS . . . WHAT IT DOES

Phytic Arid, the hexaphosphoric add 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 dif­ferent fields.

Available for the first time in commercial quantities, Phytic Acid's indicated applica­tions are: e Chelating or sequestering heavy metals, e Facilitating plating, improving adhesion

properties of metal for application of pro­tective coatings.

• Inhibits rusting, improves appearance of metal closures on glass-packed foods.

• As an excellent starting material for certain pharmaceutical derivatives.

e It may be useful in detergent applications.

• In photographic emulsions, for low fogging qualities, yet increased sensitivity.

• As an additive to various types of paints and coat­ings to inhibit corrosion, improve color, promote better adhesion to metal surfaces.

Perhaps Phytic Add will fit in with your cur­rent research plans. For free sample and far­ther information, including technical data sheets and an 80-page BIBLIOGRAPHY on PHYTIN and INOSITOL, write to:
