“…The presence of silicon in the control can be explained by the fact that silicon is an abundant element in nature that is present everywhere, even on water and its amount varies according to the region (Luz et al 2006, Larezzini andBonotto 2014). Si identified in the treatments without sodium silicate likely originated from the water used during the experiment that, although deionized, contained some neutral forms of Si that could not be completely eliminated.…”

“…However, according to international potability standards, this constituent is an important controlling agent of the toxic biological availability of aluminum in the waters, besides presenting several health benefits. Thus, internationally, the dietary recommendation between 35 and 45 mg.day −1 of silicon is recognized as important to avoid symptoms of its deficiency [22]. The main guidelines and legislations from other countries to classify silicate mineral waters suggest the following minimum levels of Si needed in the waters [23]: 17.9 mg. L −1 in Japan; 23.4 mg. L −1 in Russia; 25.3 mg. L −1 in Poland; 14.1 mg. L −1 in Spain; 18.7 mg. L −1 in Cuba; and 45.1 mg. L −1 in the USA.…”

This paper presents a novel hydrochemical and radiometric data of groundwater sampled from Serra Negra spa town, São Paulo State, Brazil. Every year, many visitors travel to the municipality, thus, recurrent analyses are recommended and necessary, as the local water is heavily consumed. However, gaps exist in this regard, especially for the groundwater selected for sampling in this paper, since there is no analytical data on its chemical composition. The results obtained were compared with the drinking water standards in relation to the analyzed parameters. The radioactivity of all analyzed samples was below the values established by the World Health Organization of 0.5 and 1 Bq. L −1 for gross alpha and beta activities, respectively. In general, the hydrochemical parameters analyzed did not exceed the reference limits established by Brazilian and international legislation, with the exception of pH for one water sample and nitrate for another. The use of Pearson's correlation coefficient reinforced the proportionality between electrical conductivity and dissolved salts. In the chemical aspect, the dominant anion in the waters was bicarbonate, agreeing with the observed pH, while the predominant cation was sodium, possibly suggesting a slightly more evolved hydrogeochemical context. Although the Brazilian legislation does not mention a reference value for the ingestion of silicon in water, in this paper some comments were made about its presence in the analyzed groundwaters.

: O envelhecimento é um processo natural, caracterizado por alterações morfológicas, bioquímicas e fisiológicas que ocorrem progressivamente no decorrer do tempo. Existem inúmeras maneiras de tratar e prevenir o envelhecimento cutâneo, entre estas destaca-se o uso cosméticos com silício orgânico. O silício orgânico é o oligoelemento, de natureza ubíqua mais abundante na terra, o corpo humano possui silício orgânico em sua composição, desde a fase fetal, sendo que com o passar do tempo suas concentrações diminuem. Este ativo apresenta diversas funções, dentre as quais pode-se citar sua atividade antioxidante e umectante, estimulante da síntese de colágeno e elastina, além de auxiliar na estruturação dérmica. Nesta perspectiva, através de uma revisão bibliográfica descritiva com abordagem qualitativa, o presente artigo tem como objetivo analisar os benefícios do silício orgânico como ativo cosmético, na prevenção do envelhecimento cutâneo. Os resultados evidenciaram que o silício apresenta diversas funções entre as quais pode-se destacar a síntese de colágeno e elastina, sendo que em conjunto, os resultados encontrados demonstraram que o silício é um ativo cosmético seguro e promissor na prevenção do envelhecimento cutâneo. Abstract: Aging is a natural process, characterized by morphological, biochemical and physiological changes that occur progressively over time. There are countless ways to treat and prevent skin aging, among which we highlight the use of cosmetics with organic silicon. Organic silicon is the most abundant ubiquitous trace element on earth, the human body has organic silicon in its composition since the fetal phase, and over time its concentrations decrease. This active has several functions, among which we can highlight the antioxidant, humectant, stimulating collagen and elastin synthesis, besides helping in dermal structuring. In this perspective, through a descriptive bibliographic review with a qualitative approach, this article aims to analyze the benefits of organic silicon as a cosmetic asset, in preventing skin aging. The results showed that silicon has several functions, among which the synthesis of collagen and elastin can be highlighted, and together, the results found showed that silicon is a safe and promising cosmetic asset in the prevention of skin aging.Keywords: Skin aging.
