While trying to find it, I found a Lubrizol one

My brain hurts from reading that patent!!! I could have gone longer in life without knowing what a Mannich Condensate is. Readers, don't read that patent if you want to preserve what neurons you have left. Have a beer and watch some football instead.
Start with this part, about Polyetheramine added to oil:
The amino compound may be characterized by the presence within its structure of at least one HN< group and can be a monoamine or polyamine. Mixtures of two or more amino compounds can be used in the reaction with one or more acylating reagents. In one embodiment, the amino compound contains at least one primary amino group (i.e., —NH2). In one embodiment, the amine is a polyamine, for example, a polyamine containing at least two —NH— groups, either or both of which are primary or secondary amines. The amines may be aliphatic, cycloaliphatic, aromatic or heterocyclic amines. Hydroxy substituted amines, such as alkanol amines (e.g., mono- or diethanol amine), and hydroxy (polyhydrocarbyloxy) anologs of such alkanol amines' may be used.
Among the useful amines are the alkylene polyamines, including the polyalkylene polyamines. The alkylene polyamines include those represented by the formula ...
... U may be ethylene or propylene. Alkylene polyamines where each R is hydrogen or an amino-substituted hydrocarbyl group with the ethylene polyamines and mixtures of ethylene polyamines are useful. Usually n will have an average value of from about 2 to about 10. Such alkylene polyamines include methylene polyamines, ethylene polyamines, propylene polyamines, butylene polyamines, pentylene polyamines, hexylene polyamines, heptylene polyamines, etc. The higher homologs of such amines and related amino alkyl-substituted piperazines are also included.
Alkylene polyamines that are useful include ethylene diamine, diethylene triamine,
triethylene tetramine, tetraethylene pentamine, pentaethylene hexamine, propylene diamine, trimethylene diamine, hexamethylene diamine, decamethylene diamine, octamethylene diamine, di(heptamethylene)triamine, tripropylene tetramine, trimethylene diamine, di(trimethylene)triamine, N-(2-aminoethyl)piperazine, 1,4-bis(2-aminoethyl)piperazine, and the like. Higher homologs such as those obtained by condensing two or more of the above-illustrated alkylene amines may be used. Mixtures of two or more of any of the afore-described polyamines may be used.
Useful polyamines include those resulting from stripping polyamine mixtures. In this instance, lower molecular weight polyamines and volatile contaminants are removed from an alkylene polyamine mixture to leave as residue what is often termed “polyamine bottoms”. In general, alkylene polyamine bottoms can be characterized as having less than about 2% by weight, and in one embodiment less than about 1% by weight material boiling below about 200° C.
But Molakule keep saying that PEA has nothing to do with EO, jut as a FSC ...
