Answer: the cosmetics themselves do not need to be reported under Phase 1, but the plastic containers they come in, like bottles, jars, or pumps, do count and must be reported if thresholds are met.
These items fall under the Federal Plastics Registry single-use or disposable products category, under the personal hygiene and care products subcategory. In the Federal Plastics Registry guidance, personal hygiene and care products include products intended for the maintenance of personal health, including grooming, brushing teeth, showering, applying makeup, washing or drying face, hands, and body, or any substance or mixture of substances manufactured, sold, or represented for use in cleaning, improving, or altering the complexion, skin, hair, or teeth, and includes deodorants and perfumes.
