Looking for an
understanding....?
Sodium POE (10) is a synonym
for Tri(laureth-4)-phosphate
(How can that be?)
A compound known
as Sodium POE (10) is a common surfactant
which contains the tri-laureth phosphate group, Tri(laureth-4)-phosphate.
Tri(laureth-4)-phosphate is not a substance that exists independently.
Question: So since this
formula Tri(laureth-4)-phosphate
has no sodium,
what would tri(laureth-4)-phosphate be combining with?
Todays inipol EAP 22
uses the less complex version of phosphate:
Phosphoric acid, dodecyl ester CAS Nr 12751-23-4
C12H26O.xH3O4P
Question, why was this ingredient
substituted?

Is
the = sign in the Oleic Acid formula a mistake? They are not equal in
