Compliance with packaging legislation (after verification of all applicable restrictions) must be detailed in the relevant DoC, which must include information on the uses for which it is safe to bring the material or article into contact with foodstuffs/cosmetics (e.g. types of food, time and temperature of use). The DoC is then evaluated by the cosmetic product safety consultant.
Plastic packaging intended to be used with cosmetic products is not obliged to comply with Regulation 10/2011, but the most practical option is probably to adopt an approach like the one taken with foodstuffs and to assume during the packaging design process that the raw materials must be suitable for food contact. Only when all agents in the supply chain are involved in compliance with legislative requirements will it be possible to guarantee the safety of packaged products.
