INITIA™ 585 is an enhanced polymaleic acid (empa) that improves upon the exceptional performance of traditional polymaleic acid (pma). INITIA™ 585 is differentiated from traditional pma in that it is optimized for adsorption onto forming mineral scales such as calcium carbonate. This optimization and improved surface adsorption results in profound distortion of forming crystal habits and provides effective threshold inhibition in demanding applications. INITIA™ 585 is designed for control of mineral scales such as calcium carbonate, calcium sulfate, and barium sulfate in a wide variety of water treatment applications.
A comparison of INITIA™ 585 and traditional pma as threshold inhibitors was conducted using a severe calcium laboratory static testing method. In this method, 50 ml of a solution containing 1200mg/l Ca2+ was added to a french square bottle and treated with the indicated polymer dosage (as active.) Then 50 ml of a solution containing sodium carbonate (150 mg/l as CO32-), sodium bicarbonate (450 mg/l as CO32-), and a borate buffer (98 mg/l B4O72-) was added to the calcium/polymer solution. All samples had a measured pH of ~9.0 and were capped and placed in a water bath at 50° C for 18 hours. The Langelier Saturation Index was calculated to be ~ 3.0. In this evaluation, INITIA™ 585 and pma were compared across increasing dosages of 5, 10, 15, and 30 mg/l on an active polymer basis. The results are show both materials to be effective with INITIA™ 585 outperforming pma at lower treatment levels.

INITIA™ 585 is supplied as a concentrated (~50%) enhanced polymaleic acid at a pH of <2.0. The neutralization INITIA™ 585 is exothermic and can produce a rapid increase in heat during formulation. INITIA™ 585 should be diluted to the desired final formulation concentration with deionized water prior to adding a neutralizing agent. Neutralizing agents should be added slowly until the desired pH is achieved. Effective neutralization is possible without observing product precipitation using either NaOH or KOH. The graphs below indicate the approximate amount of NaOH or KOH required to neutralize INITIA™ 585 to a given final pH.
