### Types of UV Filters and Their Frequency of Use in Preparations  
A detailed analysis of the UV filters found in the preparations for children (n = 50) is shown in Figure 1. The most popular substances were two triazine derivatives: bisethylhexyloxyphenylenol methoxyphenyl triazine (BEMT; Tinosorb S), found in 60.0% of the analyzed preparations, and ethylhexyl triazone (EHT), found in 52.0%. These were followed by the salicylic acid derivative--ethylhexyl salicate (EHS)--present in 46.0%. Finally, the benzophenone derivative diethylamino hydroxybenzoyl acyl hexyl benzoate (DHHB), the dibenzoylmethane derivative butyl methoxydibenzoylmethane (BMBM; Avobenzene), the physical filters titanium dioxide (non-nano) and titanium dioxide (nano), and the cinnamic acid derivative octocrylene (OC) were all found in 20% to 40%. Among the adult sunscreens (Figure 2), the largest share was demonstrated by the dibenzoylmethane derivative butyl methoxydibenzoylmethane (BMBM; Avobenzene) with 56.0% of preparations, followed by the salicylic acid derivative ethylhexyl salicate (EHS) and the triazine derivative bis-ethylhexyloxyphenyl methoxyphenyl triazine (BEMT; Tinosorb S), each present in 54.7%, and then a triazine derivative, ethylhexyl triazone (EHT), with 50.0%. The following also had significant percentage shares, ranging from 20% to 40%: diethylamino hydroxybenzoyl acyl hexyl benzoate (DHHB), the cinnamic acid derivatives octocrylene (OC) and ethylhexyl methoxycinnamate (EHMC), and phenylbenzimidazole sulfonic acid (PBSA). Hence, the most common sunscreen substances in the analyzed cosme, both for children and adults, were the organic UV filters from the group of triazine derivatives, salicylic acid derivatives, and dibenzoylmethane derivatives: butyl methoxydibenzoylmethane (BMBM; Avobenzene); bis-ethylhexyloxyphenyl methoxyphenyl triazine (BEMT; Tinosorb S); ethylhexyl salicate (EHS); ethylhexyl triazone (EHT) (Table 1). Physical filters were more common in preparations for children than for adults. Titanium dioxide (including its nano form) was present in 50.0% of child products and 21.3% of adult products, and

Methylene bis-benzotriazolyl tetramethylbutylphenol (nano); 15. Drometrizole trisiloxane; 16. Methylene bis-benzotrirazolyl tetramethylbutylphenol; 17. Bis-ethylhexylophenol methoxyphenyl triazine (BEMT; Tinosorb S); 18. Ethlyhexyl triazone (EHT); 19. Diethylhexyl butamino triazone; 20. Tris-biphenyl triazine (nano). zinc oxide (including its nano form) was found in 22.0% of child products but only 6.7% of adult products. Some of the identified UV filters were found to be relatively rare, appearing in fewer than 5% of sunscreen products. In the preparations for children, these included
