Title: THICKENED, CLEAR SALT-RICH COMPOSITION, METHOD FOR LIGHTENING SAME, AND USE THEREOF IN COSMETICS
Abstract:
The invention relates to a composition (d) comprising (per 100 % of its weight): a) between 90 wt.-% and 99.0 wt.-% water comprising, in dissolved form, between 0.002 mol/L and 0.1 mol/L of at least one salt (S) of ammonium cation or of a monovalent or multivalent metal cation (S) with an organic or inorganic anion; b) between 0.5 wt.-% and 5 wt.-% of at lest one crosslinked anionic polyelectrolyte (PA); and c) between 0.5 wt.-% and 5 wt.-% of at least one compound having formula (II): R1-(O-CH2-CH2)P-OH (II), where the weight ratio (Ra) of the crosslinked anionic polyelectrolyte (PA) to the compound of formula (II) is understood to be greater than or equal to 0.2 and less than or equal to 2.0, and the molar ratio (Rb) of the compound of formula (II) to the salt (S) is understood to be greater than or equal to 0.05 and less than or equal to 1. The invention also relates to the use of said composition in cosmetics and to a method for lightening the thickened salt-rich composition.
