(HealthDay News) – Antimicrobial endocrine-disrupting compounds commonly found in toothpaste and cosmetics are associated with a higher risk of allergic sensitization in children, according to a study published online June 18 in the Journal of Allergy and Clinical Immunology.

Jessica H Savage, MD, MHS, and colleagues from Johns Hopkins University in Baltimore, examined the association between urinary levels of endocrine-disrupting compounds (bisphenol A; triclosan; benzophenone-3; and propyl, methyl, butyl, and ethyl parabens) and allergic sensitization (immunoglobulin E levels) in 860 children aged 6–18 years.

The researchers found that increasing levels of the antimicrobials triclosan and propyl and butyl parabens were significantly more likely to produce aeroallergen sensitization (P≤0.04). For males the level of urinary triclosan correlated with increased odds of food sensitization (odds ratio for highest versus lowest tertile, 3.9; P=0.02 for trend), and males were significantly more likely to develop food sensitization linked to triclosan exposure (P=0.03). These associations were not observed with nonantimicrobial endocrine-disrupting compounds.

“Levels of the antimicrobial endocrine-disrupting compounds triclosan and parabens were significantly associated with allergic sensitization,” Savage and colleagues conclude. “Because these compounds are found in personal care products, such as toothpaste and mouthwash, and/or are commonly used as preservatives in foods, drugs, and cosmetics, they are frequently encountered in daily life in Western society.”
