    You’ll need to be more clear with your question. What exactly are you asking?

    It’s still difficult to understand exactly what you are asking, however it seems like you are saying that the product performs differently at the beginning of use than at the end.

    If that is the case I can imagine two potential causes.

    1. The polymer is chemically breaking down over time.  This could be the result of chemical reaction, environmental exposure, or microbial contamination. I don’t believe this is likely but that would explain the difference in performance. 

    2.  The polymer was not properly mixed at the beginning so more of it was at the top of the product than at the bottom. When the consumer scoops off the top layer of product, they eventually remove all the polymer so there is none left at the end. More thorough mixing might solve that problem.

    Some other reason. Without knowing all the ingredients in the formula or what you mean by “fiber effect” I can’t say much else.
