Thickened, transparent salt-rich cosmetic serums, methods for lightening hydrogels, and their use in cosmetics

摘要

The present invention relates to a process for the preparation of an aqueous emulsion comprising: a) from 0.002 mol / l to 0.1 mol / l of ammonium cations or monovalent or polyvalent metal cations (S) in dissolved form and at least one salt of an organic or inorganic anion % To 99.0 wt .-% water comprising (S); b) from 0.5 wt.% to 5 wt.% of at least one crosslinked anionic polyelectrolyte (PA); And c) from 0.5 wt.% To 5 wt.% Of at least one compound of formula (II), wherein the weight of the crosslinked anionic polyelectrolyte (PA) to the compound of formula (II) The ratio (Ra) is understood to be not less than 0.2 and not more than 2.0, and the molar ratio (R _b ) of the compound of the formula (II) to the salt (S) is understood to be not less than 0.05 and not more than 1. The present invention also relates to the use of such a composition in cosmetics and to a process for lightening thickened and salt-rich compositions. RTI ID = 0.0 &
