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 topical adhesive for attachment to the skin of articles such as protective articles, clothing, prosthesis, heat wraps, pads, and/or packs, cold wraps, hearing aids, protective face masks, ornamental articles or eye wear, or functional articles being cosmetics or cleaning articles, but excluding disposable absorbent articles such as wound dressing, sanitary napkins, pantiliners, incontinence articles or underarm sweat pads, said topical adhesive being provided as a layer having thickness C measured in millimeters (mm), 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. F.), G"".sub.25, characterized in that said viscous modulus G"".sub.25 (100 rad/sec) of said topical adhesive of said topical adhesive and said thickness C satisfy the following equation:G""25.ltoreq.[(4.26+C).multidot.1605]Paand wherein the ratioG'37 (100 rad/sec)-G""37 (100 rad/sec)G""37 (1 rad/sec)-G""37 (1 rad/sec)is in the range 1 to 1.8.
