Toxic substances in cosmetic preparations

Cosmetic preparations contain a large number of toxic ingredients. These compounds can have a number of negative consequences, most often in the form of allergic reactions, skin irritations, hormonal disorders, increased risk of cancer. These chemicals are most often added to protect, soften or otherwise make the product more usable. The aim of this study was to determine the presence of some toxic substances by qualitative analysis of cosmetic products using the GC-MS method and to compare them with the data stated on the product declaration. A total of 66 samples were analysed: 10 baby shampoos and bath products, 26 cosmetic products for the axillary area and 30 samples of creams and serums. In 4 samples of baby shampoos and bath products (40 %) the presence of harmful ingredients was proven (parabens and phenoxyethanol), while diethyl phtalate was detected in all samples but was not stated in any of the declarations of these samples. Parabens were detected in 7.7 % of the products for application in the axillary area and diethyl phtalate was detected in 19 % of these samples. In 24 samples of creams and serums (80%) the presence of toxic substances buthylhydroxytoluene, cyclopentasiloxane, cyclotetrasyloxan, benzophenone, triethanolamine, phenoxyethanol, diethylphthalate was noted. These studies have proven the deviation of the actual undesirable substances in the samples from those declared. Phthalates were most often not declared on products. Better regulation of product declarations is needed, as well as stricter controls on the impact of primary packaging on product composition after packaging.
