"Emmoliate" apparently means "to moisturize". It also seems to be a technical term used mainly in the cosmetics industry ("be sure to properly emolliate after a sun-tan"). It seems to have the exact same meaning as "moisturize"(the skin) but I'm sure many "professionals" think "emmoliate" makes them sound smarter.
I think that you would do well to note that many dictionaries don't have this term, and avoid it in favour of "moisturize". Unless of course, you work in cosmetics in which case you can have fun explaining this to everyone curious.
Well, apologies for that. Those same dictionaries list the definition as
"to soften or make effeminate".
Here, we can see the possible etymological relation to emmoliate (perhaps even, I daresay, a misspelling of the same word).
Of course I see that you have already settled on possibly the wisest choice, just avoid the word.
