Use of an aqueous silica sol for obtaining a stabilized pickled white or stabilized white from a skin, in particular by treating a skin at a pH between 1 and 8, at room temperature, in an aqueous or brine bath with a density between 1.014 and 1.09, with an aqueous silica sol containing 10 to 50% by weight of silica in the form of discrete particles, not linked together by siloxane bonds and having a mean diameter between 3 and 100 nm, and process for obtaining a pickled white. |
