Abstract: The adhesive capability of matrix-type transdermal devices for the delivery of drugs, cosmetics, emollients and the like is altered by incorporating into the pressure-sensitive adhesive an effective amount of a polydiorganosiloxane polymer fluid adhesion adjusting agent. The properties of the pressure-sensitive adhesive are modified to enable a matrix-type patch to adhere temporarily to the skin for a period sufficient to accomplish its desired delivery purpose and then be removed without causing skin damage or irritation and without leaving substantial adhesive residue on the skin. Polydimethylsiloxanes (dimethicones) are preferred adhesion adjusting agents and acrylic-based polymers are preferred pressure-sensitive adhesives. Matrix-type patches containing anti-wrinkle agents formulated with dimethicones in the adhesive for application to areas on the face and particularly around the eyes are especially useful.
