The present invention relates to the use, for adhesion on hair or fiber-populated surfaces, of hydrogel adhesive characterized by a G', (1 rad/sec) or below 1000 Pa, resulting in embedding of the hair of fiber and good adhesion properties on the surface. The invention also encompasses Personal Care Products and Surface Care Articles containing the hydrogel compositions herein.

Hydrogel adhesives for use on hair or fiber-populated surfaces

The invention is a disposable absorbent article for topical adhesive attachment to a wearer. The article has a wearer facing surface and a garment facing surface and comprises an absorbent core. The article comprises an adhesive on at least the wearer facing surface. The adhesive has a dynamic elastic behaviour so that the difference between G&prime;37 at a frequency of 1 rad/sec and G&prime;37 at a frequency of 100 rad/sec is not greater than 150% of G&prime;37 at a frequency of 1 rad/sec. The adhesive has a dynamic viscous behavior so that the difference between G&Prime;37 at a frequency of 1 rad/sec and G&Prime;37 at a frequency of 100 rad/sec is not greater than 10,000 Pa. The ratio G&prime;37 over G&Prime;37 in the frequency range 1-100 rad/s is greater or equal to 3.3.
