Applicant's summary and conclusion

Conclusions:
The reaction product is a white powder containing up to 60% water. The product is a mixture of a few products of the reaction mixture with unpredictable length, size and complexity. Moreover, the product, which consists of a mixture of a large number of closely related compounds, is totally amorphous.
Thus, the product is suggested to be characterized under REACH as a substance of Unknown or Variable composition, Complex reaction products or Biological material (UVCB) substance. Please see also attached background material.
