Abstract: The present invention relates to topical adhesives for attachment to the skin. In particular the present invention relates to such topical adhesives which can be employed for attachment to the skin of articles such as protective articles, clothing, prosthesis, heat wraps, pads, and/or packs, e.g. for topical relief of pain or simply to provide warmth, cold wraps hearing aids, protective face masks, ornamental articles or eye wear, but excluding absorbent articles, or also of functional articles such as cosmetic or pharmaceutical delivery articles that provide a substance to the skin, decorative cosmetics or cleaning articles. The topical adhesive provides secure attachment and is pleasing to the skin upon application, yet causes no discomfort upon removal. This is achieved by selecting the characteristics of the topical adhesives, particularly the viscous modulus G″ in combination with the thickness C of the topical adhesive layer in which the adhesive is provided for attachment to the skin.
