In addition to the above examples, other products
reformulated and commercialized include Crystal Growth
Modifiers and Filtering aids for which APEO free versions
are available.
In summary, even though obtaining equivalent per-
formance is a high priority goal, other factors such as cost
for making, raw material availability and supply chain, and
manufacturing and process capabilities have significant
impact on determining feasibility and commercialization of
