1. A disposable absorbent article having a longitudinal centerline and a lateral centerline, a front waist region with a front waist edge, a rear waist region with a rear waist edge, a crotch region disposed between said front and rear waist regions and two spaced apart longitudinal side edges joining said front waist edge to said rear waist edge and comprising an assembly of components including:
a) a topsheet; b) a backsheet underlying said topsheet; c) an absorbent core disposed between said topsheet and said backsheet, wherein said absorbent core comprises at least one of a core cover, a dusting layer, an acquisition layer, a distribution layer and a storage member; d) at least one additional component selected from the group consisting of:
i) a fastening system for joining said front waist region to said rear waist region when said absorbent article is worn;ii) barrier cuffs lying adjacent and inboard one of said longitudinal side edges;iii) gasketing cuffs lying between said longitudinal side edge and said barrier cuff;iv) front ears disposed in said front waist region;v) back ears disposed in said rear waist region; andvi) a receiving member; and e) a hot melt adhesive composition suitable for joining at least two absorbent article components together, wherein said adhesive comprises:
(i) about 40-70 wt. % of an amorphous polyolefin composition comprising greater than 40 mole % 1-butene;(ii) about 70-40 wt. % of a heterophase polyolefin composition having a molecular weight (Mw) less than 10,000, comprising a propene and a monomer selected from ethylene, 1-hexene, 1-octene or combinations thereof; and(iii) about 0.1 to 30 wt. % of a polyisobutylene plasticizer polymerized with AlCl3 and having a molecular weight (Mw) of 200-5000. |
