We tested the product you delivered on December 10th, 2008, comparing it with the sample you had sent for testing in 2007. We noticed that the product of 2008 makes a good deal of foam and the product of 2007 makes a little, they are different.
Why are they different?
Why does the product of 2008 make more foam?
Urgently awaiting a written response, I send best regards.
