Barium sulphate is an inert, insoluble inorganic compound used in cosmetics primarily as an opacifying agent and white pigment filler. It is chemically stable and not absorbed through intact skin.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation | Rare | Mild irritation possible in sensitive individuals, generally low due to inertness |
| Contact dermatitis | Very rare | Allergic reactions are uncommon given its inert, insoluble nature |
| Mechanical pore occlusion | Rare | Particulate filler may theoretically contribute to occlusion in heavy formulations |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
