Dicalcium phosphate is a mineral salt used in skincare and oral care products primarily as a mild abrasive, bulking agent, and texturizer. It is considered a base/formulation ingredient rather than a therapeutic active.
| Reported effect | How often | Notes |
|---|---|---|
Mild mechanical irritation | Rare | Possible with abrasive use on sensitive or compromised skin |
Contact dermatitis | Very rare | Allergic sensitization is uncommon for this inert mineral |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
