>Apparently, the European community has also adopted this INCI label language. I would be interested to know if anyone in this forum is involved with packaging of retail consumer products like shampoos and foam baths, and if they are following these rules

There was quite a discussion about this here on one of those endless consumer programmes. The word aqua has appeared on labels for products like shampoo, foam baths etc. As the items that form the largest constituent of the product are shown first, inevitably many products have aqua as the first listed constituent. Several people commented that the change to "aqua" sounded much better than acknowledging that the rather expensive product you had just bought was little more than water. In the end it was revealed as a new EU ruling to continue the standardisation of the United States of Europe.
