 I am responsible for the phosphoric acid esters called Hordaphos
and I will try to answer your questions:

- In our Hordaphos product range we have no triesters [ general formular

- The phosphoric acid, dodecylester with the CAS-Nr. 12751-23-4
   is no pure triester, but a mixture of mono- and diester.
   We have a similar product which calls Hordaphos MDL.

- The given formula [C12H25(OC2H4)3O]3PO] refers to
   a phosphoric ester based on an ethoxilated lauryl (=C12) alcohol.

- I think Bayer produces some phosphoric acid triesters.

- I am sorry, but concerning the EAP22 I cannot help you.

If you have further questions concerning Hordaphos, please contact me.

Best regards
W. Maas
