O protetor solar um produto extremamente importante para proteger a pele da radiao ultravioleta proveniente do sol e capaz de reduzir a incidncia de cncer de pele. Os filtros solares so divididos em orgnicos e inorgnicos e, dentre os inorgnicos, se encontra o TiO2 que atua refletindo, espalhando e absorvendo as radiaes UV, alm de ser fotoestvel e de baixo potencial de irritabilidade drmica. Neste trabalho foram desenvolvidas formulaes cosmticas em forma de gel contendo nanopartculas de dixido de titnio capazes de agir como fotoprotetores fsicos e que mantem a transparncia ao serem aplicados sobre uma superfcie, como a pele. Foram desenvolvidos xerogis a base de nanopartculas de TiO2 com tamanho e superfcie controlados. A partir dessas nanopartculas foi possvel preparar formulaes cosmticas contendo nanopartculas redispersas de xerogis a base de TiO2. Esses sistemas foram avaliados por testes de citotoxicidade e foi obtido um resultado favorvel para a continuidade da pesquisa, sugerindo o uso deste material em humanos sem causar danos. Foram feitas as caracterizaes fsico qumicas e estruturais. A anlise de FPS indicou amplo espectro da formulao, o potencial zeta mostrou que possvel evitar aglomeraes das nanopartculas em pHs utilizados para formulaes tpicas, a reologia demonstrou que as formulaes apresentam comportamento de recuperao da consistncia e organizao do material inicial aps seu desarranjo durante o cisalhamento. As caracterizaes serviram para obter um conhecimento da estrutura qumica e fsica das amostras que contm as nanopartculas de dixido de titnio, para que seja possvel fazer uma anlise crtica e melhor qualificar o protetor solar desenvolvido.

The goal of this paper is to critically analyze the practices developed by Solidarity Economy and to merge them with social technologies, aiming to achieve social transformation of popular groups. This transformation consists in the empowerment of those groups in means of work organization, considering their self-management and also the development of techniques and technologies utilized. Based on the understanding that technical development has no neutral character and it follows linearity within society, a discussion around the forms and uses of technology is conducted here, aiming at the perspective of changes in technologies development and also assigning social character to them. To think of social technology requires us to consider the space in which it is inserted, once it refers to a collective demand that belongs to self-managed groups. Therefore, to intent beyond self-management work, new productive forces are discussed here, and also the analysis and adhesion of an alternative technology for popular cooperatives

Fluoridation of water for human consumption is a method of caries prevention that brings great social benefit, if kept at optimal levels. The increase in the production of bottled water emphasizes the need to verify whether fluoride presence in these waters occurs in sufficient quantity to prevent decay, or if it represents a significant risk of fluorosis. Objective: to compare the concentrations of fluoride present in bottled water to those declared on the labels, and to make a critical analysis of legal norms on the subject. Materials and method: this was a cross-sectional study, through which 22 samples of bottled water sold in state of Cear, Brazil, were analyzed. Analyses were performed in duplicate by the electrometric method, and results were compared to those printed on the labels. Detailed searches by laws, resolutions, ordinances, and other official documents in force, related to the topic were performed. Results: the fluoride concentrations found ranged from 0.01 to 0.36 mgF/l. Although 72.7% of the samples were classified as fluoridated, the fluoride concentrations observed were shown to be insufficient for caries prevention. As for the rules, situations where they are not clear or even divergent were found. Conclusion: the current legislation on the subject requires updates to become more objective and to create new criteria on the use of the term fluoridated water.
