When submitting a proposal or revision... what is the best practice for listing the perfumer name(s) when both the name of the house the individual people are known? Do you list both if you know both? Or do you only list the house when individual name(s) are unknown?
E.g. would you list both [a person's name] and "IFF (International Flavors & Fragrances)"?
I think the questioner is not concerned with brands, but with ‘perfume manufacturer associations’
We don't have such a clear rule, it depends on the case.
For example: A brand states: ‘Our perfume was developed by IFF perfumers A and B.’
In this case, the names of the perfumers would suffice, it doesn't matter where they are employed.
Example 2: A brand states "Our perfume was developed by IFF with the collaboration of perfumers A and B"
Here it is not clear whether perfumers A and B were the only ones involved in the fragrance, or whether other IFF perfumers were involved, so you could enter all three here, i.e. the names of those mentioned plus IFF.
In case of doubt, however, it is always better to give the specific names than the company, so you never go wrong.
@Aspasia0 thank you so much for clarifying on this (and for understanding what was being referred to) - I'm glad you chimed in, since I clearly wasn't addressing the right topic! I'll delete my responses so as not to confuse 😅
Thank you @Aspasia0, that was what I was trying to ask about. I'll just err on the side of providing everything and letting reviewers remove it if they want to 
What do we do when the wrong perfumer is listed? I found one I'd like to correct...
@AriLynn scroll down to the "Research" button on any fragrance page, then "New Revision" top right, edit Perfumer + "Submit Revision", and then attach the proof via screenshot/link from an official brand source!
