Expert Verdict
Severe - estrogenic endocrine disruptor; promotes estrogen-dependent tumor growth; systemic absorption through skin; reproductive toxicity; classified as CMR (Carcinogenic, Mutagenic, Reprotoxic). The 16-beta methyl substitution modifies the pharmacological profile of estradiol; propanoate ester form provides lipophilicity for skin penetration - which is precisely why it is now prohibited in cosmetics globally
