Prevalence of Contact Allergens in Personal Care Products for Babies and Children

BACKGROUND: Personal care products marketed for babies and children are often regarded as "safe" or "gentle." However, little is known about the prevalence of contact allergens in these types of products. OBJECTIVE: This study assessed the prevalence of important sensitizers in personal care products marketed for babies and children. A secondary objective of this study was to determine whether a product's cost correlates with content of sensitizing ingredients. METHODS: The ingredient lists of 533 unique personal care products were analyzed for presence of fragrance, betaines, propylene glycol, methylchloroisothiazolinone, methylisothiazolinone, formaldehyde, lanolin, and neomycin. Price per ounce was determined for each product as well. CONCLUSIONS: Most personal care products for babies and children contain 1 or more sensitizers. Products containing more sensitizers tend to cost less than those without any sensitizing ingredients.
