Having recently worked at Chanel Inc. Piscataway NJ. Their global factory for fragrances, as well a creams, lotions, lip gloss, etc. I was very much impressed as to how many times their raw ingredients were checked for bacteria, even before they were allowed into their factory for production, during storage, prior to production, during production and upon completion. Unless their product was perfect. It was destroyed.
Being that they are so close in proximity to NYC, I would encourage you to ask them for a visit?
