ONDEO Nalco

Erythorbic acid is available as a 98+% Food Chemical Codex product (as per Pfizer sodium erythorbate FCC, although as Pfizer is now a pharmaceuticals company, much of the world s erythorbate is now supplied from China and other Asian countries) and in many diluted or blended forms, such as Nalco Sur-Gard . The ONDEO Nalco material is typical of products used within the industry, being based on erythorbic acid buffered with amine. A 1% solution of the product has a pH level of 6.3. 

As a result, various non-amine-based products have been introduced to the market that continue to provide appropriate levels of corrosion protection, yet do not exhibit the limitations normally associated with amines. The most promising of these are the sorbitan-based, nonionic surfactant treatments, such as those marketed by ONDEO Nalco under the Tri-Act brand (U.S. patent 5,849,220, December 1998).
