| Reported effect | How often | Notes |
|---|---|---|
Mild skin irritation | Uncommon | Transient stinging or redness, more likely on compromised or sensitive skin. |
Allergic contact dermatitis | Rare | Sensitization is infrequent; propanediol is generally considered low-risk for allergy. |
Enhanced penetration of co-formulated irritants | Uncommon | As a penetration enhancer it may increase absorption and irritation potential of other actives. |
