Butyl Methoxydibenzoylmethane 3%
Medium RiskButyl methoxydibenzoylmethane (avobenzone) is a UVA filter used in sunscreens. Reviews note potential endocrine-related signals for several organic UV filters, but data are often not sufficient to establish endocrine disruption, and systemic exposure depends on formulation and use pattern. Pregnancy-specific human outcome data for topical exposure are limited; the key signal is uncertainty around systemic/endocrine effects rather than a well-defined pregnancy outcome dataset.
