Background: Cosmetics for children recommended by opinion-forming institutions should be safe, best non-fragrances and well tolerated. However, these products like any other cosmetics may contain sensitizers or irritants.
The aim was analysis with regard to the presence of ingredients with known sensitizing and irritating potential in declared composition of cosmetics recommended by medical societies and research and development units.
Material and methods: The selection of cosmetics, was based on words including in name or in description, stating that the product is intended for children as well as information about a recommendation of the product by Institute of Mother and Child, Children's Health Centre, Polish Society of Allergology or Polish Pediatric Society. Cosmetics from each institution were divided into two groups- "rinse-off" and " live on". The composition of cosmetics were analyzed for the occurrence of sensitizers or irritants. For this purpose, European Cosing base was used. The differences in frequency of the occurrence the "problematic" substances were analyzed by Chi2 test. The differences between results distribution in tested categories of products were compared using statistic U Mann-Whitney test.
Results: Among 204 recommended products for children (76 recommended by Institute of Mother and Child, 97 recommended by Children's Health Centre, 46 recommended by Polish Society of Allergology or Polish Pediatric Society) 522 (100%) different ingredients have been identified therein 19 fragrances, 18 colorants, 20 preservatives, 11 UV filters and 13 "problematic" substances with different functions. Only 3,43% of the tested products were free from ingredients with known sensitizing and irritating potential. Cosmetics leave-on recommended by Children's Health Centre significantly more often than recommended by other institutions included sensitizing fragrances: linalool (p=0,003), limonene (p=0,003), geraniol (p=0,003), coumarin (p=0,003), citronellol (p=0,048) cinnamyl alcohol (p=0,032) i alpha-isomethyl ionone (p=0,018). The number of preservatives in cosmetics with recommendation of Children's Health Centre was significantly higher (median=2) than in products recommended by Institute of Mother and Child (median=1) and medical societies (median=1). Products with recommendation of medical sciences societies contained more colorants (median=1) than other recommended products (median=0).
Conclusions: The vast majority of cosmetics recommended by Institute of Mother and Child, Children's Health Centre, Polish Society of Allergology, Polish Pediatric Society contain ingredients with known sensitizing and irritating potential. Only a few products are free from substances with known sensitizing and irritating potential. Cosmetics recommended by each opinion-forming institution differ in frequency of occurrence ingredients approved for use with restricted concentration (fragrances including substances with general term "parfum" ("fragrance", "aroma"), colorants, preservatives, UV-filters, substances approved for used with restrictions of another functions. Alarmingly enough, that "leave-on" cosmetics contain usually more ingredients than "rinse-off" products.
