ANÁLISE FOTOQUÍMICA E MICROBIOLÓGICA DE PROTETORES SOLARES PRODUZIDOS NAS FARMÁCIAS DE COLATINA–ES

UVA and UVB radiation from the sun reaches the surface of the skin and can cause DNA damage by photochemical mechanisms. Chemical compounds contained in anti-suns are important for photoprotection because they block UV radiation preventing damage to human skin. Many of the protectors are produced in drugstores of Colatina-ES, however, there is no information to consumers about the quality of the products. A sunscreen contaminated with microorganisms can interfere with effectiveness as well as the sun protection factor and cause premature aging of the skin. Therefore, it is necessary the microbiological and photochemical analysis of the manipulated photoprotectors. Samples of sunscreens produced in six drugstores of Colatina city were submitted to microbiological analysis. Statistical analyzes of variance (ANOVA) were performed in triplicate a p <0.05. Selective agaves were used as culture medium. Although they belong to the normal microbiota, Staphylococcus aureus was found in all samples evaluated. The detection may be associated with incorrect procedures in the handling process. On the other hand, all the manipulated had chemical structures capable of protecting the skin against UVA and UVB irradiation since the inorganic and organic photoprotectors found reach the UV protection range.
