Abstract
The disclosure generally relates to pressure-sensitive adhesive compositions and self-adhering wound dressings, and more particularly, to pressure-sensitive adhesive compositions comprising a triblock copolymer and a superabsorbent material and self-adhering wound dressings comprising same. The adhesive compositions are skinfriendly and therefore may be used in medical environments where a dressing, bandage, ostomy pouch, continence care appliance, transdermal drug delivery patch, or similar article is intended to be adhered to the skin. The self-adhering wound dressings are also skinfriendly.
Claims21
A pressure-sensitive adhesive composition comprising:
- about 0.25 weight percent (wt. %) to about 15 wt. % of a high molecular weight rubber triblock copolymer;
- about 35 wt. % to about 65 wt. % of a superabsorbent material;
- 0 wt. % to about 15 wt. % of a high molecular weight diblock rubber;
- 0 wt. % to about 20 wt. % of an end block resin;
- 0 wt. % to about 40 wt. % of a diluent;
- 0 wt. % to about 35 wt. % of a solid tackifier;
- 0 wt. % to about 20 wt. % of a hydrocolloid comprising a natural product or a modified natural product;
- and,
- 0 wt. % to about 10 wt. % of a semi-solid hydrocarbon.
A waste collection appliance comprising:
- a mounting faceplate;
- and,
- a waste collection pouch comprising a polymeric material,
- wherein the mounting faceplate includes a layer of pressure-sensitive adhesive composition comprising about 0.25 weight percent (wt. %) to about 15 wt. % of a high molecular weight rubber triblock copolymer, about 35 wt. % to about 65 wt. % of a superabsorbent material, 0 wt. % to about 15 wt. % of a high molecular weight diblock rubber, 0 wt. % to about 20 wt. % of an end block resin, 0 wt. % to about 40 wt. % of a diluent, 0 wt. % to about 35 wt. % of a solid tackifier, 0 wt. % to about 20 wt. % of a hydrocolloid comprising a natural product or a modified natural product, and 0 wt. % to about 10 wt. % of a semi-solid hydrocarbon.
A pressure-sensitive adhesive composition comprising:
- about 0.25 weight percent (wt. %) to about 15 wt. % of a high molecular weight rubber triblock copolymer;
- and,
- about 35 wt. % to about 65 wt. % of a superabsorbent material,
- wherein the adhesive composition has a compressive force of less than about 15 pounds per square inch (psi) at 10 percent (%) strain.
A self-adhering wound dressing comprising about 0.25 weight percent (wt. %) to about 15 wt. % of a high molecular weight rubber triblock copolymer, about 35 wt. % to about 65 wt. % of a superabsorbent material, 0 wt. % to about 15 wt. % of a high molecular weight diblock rubber, 0 wt. % to about 20 wt. % of an end block resin, 0 wt. % to about 40 wt. % of a liquid diluent, 0 wt. % to about 35 wt. % of a solid tackifier, 0 wt. % to about 20 wt. % of a hydrocolloid comprising a natural product or a modified natural product, and 0 wt. % to about 10 wt. % of a semi-solid hydrocarbon.
