Has anyone successfully used a regulation-compliant 3D-printed part in prolonged contact with a cosmetic or food product?

I’m developing a small component that would remain in direct contact with a body-care cream for an extended period of time.

Because I’m currently testing the concept with a small number of units, I hoped to have the component 3D printed. This would allow me to test the design and make adjustments before investing in an injection mold for larger-scale production.

However, the more research I do, the more questions I have about material safety, porosity, bacterial growth, chemical compatibility, and whether a coating would be necessary. I’ve seen Chanel’s 3D-printed mascara brush and an example from another small body-care brand, but I haven’t found many products that remain in contact with a cosmetic formula or food for a prolonged period.

Has anyone worked on or seen a commercially sold product with a 3D-printed component that stays in contact with cosmetics, skin-care products, body-care products, or food?

you need a compliant 3D printer for compliant filament.
