Abstract:
A combination of a substrate with a hydrophobic topical adhesive applied thereon, said adhesive comprising at least 80% by weight of hydrophobic components, said combination intended for attachment of a disposable absorbent article to the skin, said combination having a stiffness S measured in grams (g) according to the Flexibility Test herein, said topical adhesive having an elastic modulus at a temperature of 37.degree. C. (100.degree. F.), G'37, in the range of 3000 Pa to 10000 Pa, a viscous modulus at a temperature of 37.degree. C. (100.degree. F.), G""37, in the range of 300 Pa to 5000 Pa, a viscous modulus at a temperature of 25.degree. C. (77.degree.
