Abstract
A polysiloxane adhesive composition that is useful in attaching products to human skin. A disposable absorbent product may be prepared that includes the polysiloxane adhesive composition and that may be adhered directly to human skin and peeled off after use with little or no pain to the wearer. In one embodiment, the polysiloxane adhesive composition exhibits a shear storage modulus value, as measured at about 20.degree. C. and at about 10 radians per second, of less than about 1.times.10.sup.5 dynes per square centimeter; a hardness value of less than about 5 durometer units (Shore 00), a tan delta value, as measured at about 20.degree. C. and at a frequency of about 10 radians per second, of between about 0.4 to about 2.0; and a maximum peel strength value of between about 35 to about 900 grams of force per 13 millimeters of width, as measured at a peel rate range of 0 to about 5000 millimeters per minute.
