Sodium isobutyl 4-oxidobenzoate: Isobutylparaben is in the parabens family of preservatives used by the food, pharmaceutical, and personal care product industries. Parabens mimic estrogen, are potential hormone (endocrine) system disruptors, and were found in the breast cancer tumors of 19 of 20 women studied (Darbre 2004). The Centers for Disease Control and Prevention (CDC) tested urine from a group of 2,548 Americans over the age of 6 and found parabens in over 99% of samples (Calafat 2010). Isobutylparaben is closely related to butylparaben, a compound considered to be a potential human endocrine system disruptor by the European Commission on Endocrine Disruption (EU 2007). Isobutylparaben appears to be more strongly estrogenic than butylparaben (Darbre 2002, Vo 2010), but receives a lower hazard score in Skin Deep because of the limited amount of toxicological research on this chemical. Subsequent research and agency assessments may find isobutylparaben to be as or more hazardous to the endocrine system than butylparaben.
