Title
(EN) ABSORBENT ARTICLE CONTAINING A PARTICULATE SUPERABSORBENT POLYMER COMPOSITION HAVING IMPROVED STABILITY AND FAST ABSORPTION
(FR) ARTICLE ABSORBANT CONTENANT UNE COMPOSITION DE POLYMÈRE SUPERABSORBANT PARTICULAIRE AYANT UNE STABILITÉ AMÉLIORÉE ET UNE ABSORPTION RAPIDE
Abstract
(EN)
The present invention relates to an absorbent article comprising a topsheet, backsheet, and an absorbent core disposed between the topsheet and backsheet, the absorbent core comprising a fast particulate superabsorbent polymer composition comprising a polymer comprising a neutralized aluminum salt solution applied to the surface of a particulate superabsorbent polymer; wherein an aqueous solution of the neutralized aluminum salt has a pH value from about 5.5 to about 8; and subsequent to subjecting the particulate superabsorbent polymer composition to the Processing Test, the particulate superabsorbent polymer composition has a permeability stability index of from about 0.60 to about 0.99, and a compressibility from 1.30mm2/N to about 4mm2/N as measured by the Compression Test, and wherein the particulate superabsorbent polymer having a Vortex time of from 25 to 60 seconds and absorbency under load at 0.9psi of from 15 to 21g/g.
