Nylon-12 is a synthetic polyamide powder used in cosmetics to improve texture, absorb oil and sebum, and provide a smooth, mattifying feel. It functions primarily as a bulking and slip-modifying agent in formulations such as powders, primers, and color cosmetics.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation or sensitivity | Rare | Generally considered non-irritating; mild reactions are uncommon and usually mild. |
| Contact dermatitis or allergic reaction | Very rare | Rarely reported; the polymer is largely inert and not a common sensitizer. |
| Pore congestion in acne-prone skin | Rare | Occlusive potential is low, but heavy use in some may contribute to clogged pores. |
