This report reviews the safety of Aluminum, Calcium, Lithium Magnesium, Lithium Magnesium Sodium, Magnesium Aluminum, Magnesium, Sodium Magnesium, and Zirconium Silicates, Magnesium Trisilicate, Attapulgite, Bentonite, Fuller’s Earth, Hectorite, Kaolin, Montmorillonite, Pyrophyllite, and Zeolite as used in cosmetic formulations. The common aspect of all these claylike ingredients is that they c...
متن کاملLithium and beryllium hypophosphites.
The structures of monoclinic (C2/m) lithium dihydrogenphosphate, LiH2PO2, and tetragonal (P41212) beryllium bis(dihydrogenphosphate), Be(H2PO2)2, have been determined by single-crystal X-ray diffraction. The structures consist of layers of hypophosphite anions and metal cations in tetrahedral coordination by O atoms. Within the layers, the anions bridge four Li and two Be cations, respectively....
متن کاملDistrontium lithium beryllium triborate, Sr2LiBeB3O8
Single crystals of distrontium lithium beryllium triborate, Sr(2)LiBeB(3)O(8), were obtained by spontaneous nucleation from a high-temperature melt. In the Sr(2)Li[BeB(3)O(8)] structure, [BeB(2)O(7)](6-) rings, made up from one BeO(4) tetra-hedron and two BO(3) triangles, are connected to each other by [BO(3)] triangles to form the smallest repeat unit {[BeB(3)O(8)](8-)} and then form chains al...
متن کاملPhotorecombination of Metastable Beryllium-like Xenon Ions
Dielectronic recombination (DR) of beryllium-like Xe was investigated by using the ESR electron cooler as a free electron target. Three series of resonances associated with excitations from the 2s ground state could be measured (Fig. 1), namely 2s → 2s2p P1, 2s → 2s2p P1 and 2s → 2s2p P2. The resonances of the 2s2p P2 nj manifolds are much weaker than the ones of the other series. No signatures...
متن کاملLithium and Aluminum Anthracenyldiimidosulfinates
9,10-Dibromo-anthracene was lithiated once or twice, and the products were reacted with different sulfurdiimides. The reactions yielded [(THF)2Li(NBu)2SAnBr] (1), [(Et2O)(LiBr)Li(NBu)2SAnBr]2 (2), [Me2Al(NBu)2SAnBr] (3), [{(THF)2Li(NR)2S}2An] (4: R = tBu; 5: R = SiMe3) and [{Me2Al(NSiMe3)2S}2An] (6). All products were fully characterized by X-ray structure analysis, elemental analysis, NMR and ...
