Abstract
Some chemical components in sun cream filters have endocrine-disrupting activity or can be carcinogenic, neurotoxic, bioaccumulative, allergens, or be toxic for human reproduction. It is important that sunscreens have safety requirements. The objective of this work is to compare sun cream filters used in conventional commercial sunscreens and those that are considered natural products, especially focused on endocrine-disrupting effects. In order to achieve the above objective, the compositions of different conventional and natural sun cream filters were evaluated and compared, taking into account the presence of the different sun cream filters whose effects were evaluated on the website specialized in safety and cosmetics, Environmental Working Group (EWG), and in the Register of chemical substances and mixtures in the EU Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) Regulation. The currently available evidence of each sun cream filter and their degree of safety has been summarized. Several organic sun cream filters present a potential risk to health and the environment; however, inorganic sun cream filters such as titanium dioxide and zinc oxide (ZnO and TiO2) show a very low risk in humans as they are not absorbed through intact or damaged tissues. The legislation does not oblige manufacturers to specify the concentration of each substance, which provides qualitative but not quantitative information for the consumer.
