Sodium Sulfate is used as a viscosity increasing agent in cosmetic formulations, at concentrations that are reportedly as high as 97%. No evidence of systemic taxicity was seen in oral exposure studies in animals, although there was moderate ocular irritation in rabbits when a granular sodium carbonate-Sodium Sulfate mixture was instilled. No developmental or reproductive toxicity was reported ...

The discovery of hydrogen-rich waters preserved below the Earth's surface in Precambrian rocks worldwide expands our understanding of the habitability of the terrestrial subsurface. Many deep microbial ecosystems in these waters survive by coupling hydrogen oxidation to sulfate reduction. Hydrogen originates from water-rock reactions including serpentinization and radiolytic decomposition of wa...

Problem formulation. Ecological quality of soils and agricultural products depends on the level irrigation water mineralization. The mineralized has a negative impact soils, ecosystems. This is especially in conditions Southern Ukraine within Black Sea territories where formation waters Ingulets river basin influence Kryvyi Rih iron ore located basin. aim article to assess natural Materials met...

The underground space of the Kupol deposit is analyzed as a multicomponent system – rocks, water, microbiota, gases (including mine atmosphere) and supporting structures metal support shotcrete (as an additional type barring) also stowing materials. complex host rocks highly disintegrated due to active tectonic volcanic activity in Cretaceous period. thickness sub-permafrost reaches 250-300 m. ...

Ionic liquids based on 1-alkyl-3-methylimidazolium cations and the hydrogen sulfate (or bisulfate) anion, HSO(4)(-), are much more viscous than ionic liquids with alkyl sulfates, RSO(4)(-). The structural origin of the high viscosity of HSO(4)(-) ionic liquids is unraveled from detailed comparison of the anion Raman bands in 1-ethyl-3-methylimidazolium hydrogen sulfate and 1-butyl-3-methylimida...

The cations and anions of the title salt, 3C(6)H(16)N(+)·HSO(4) (-)·SO(4) (2-), are linked by N-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional network. The hydrogensulfate ion, with a single S-O(H) bond of 1.563 (2) Å, forms a short O-H⋯O hydrogen bond [O⋯O = 2.609 (2) Å] to the sulfate ion. The hydrogensulfate ion accepts two hydrogen bonds from two cations, whereas the sulfate ion, as ...

In this work, nanopowders (NP) Co(OH)2 were obtained by chemical precipitation from aqueous solutions of cobalt nitrate Co(NO3)2 and alkali NaOH (10 wt. %) using surfactants: sodium dodecyl sulfate (SDS) cetylpyridinium chloride (CPC) (0.1 %). It was shown that NP with 0.1% SDS is the best quality product, since its dispersion increases more than 2 times compared to samples CPC without surfacta...
