Ethylhexyl methoxycinnamate (octinoxate) is a widely used organic UVB-absorbing filter that helps protect skin from sunburn and UV-induced damage. It is commonly incorporated into sunscreens and daily-wear cosmetics with SPF claims.
| Reported effect | How often | Notes |
|---|---|---|
Contact irritation | Uncommon | Mild stinging or redness, more likely on sensitive or compromised skin. |
Allergic contact dermatitis | Rare | Documented in patch-test studies, though less common than with some other UV filters. |
Photoallergic/photocontact dermatitis | Rare | Reactions occurring only with concurrent UV exposure. |
Eye irritation | Uncommon | Can cause stinging if product migrates into the eyes. |
Potential endocrine activity | Very rare | Weak estrogenic effects reported in some in-vitro and animal studies; clinical relevance at cosmetic exposures remains debated. |
