Abstract
An antimicrobial composition which comprises an active agent that reduces the spread of pathogens. The active agent is mixed with a water-soluble polymer in order to form a mixture, in which the polymer forms a continuous phase, from which the active agent is capable of being released. The composition can be used to produce objects, for example elongated extrudates, which can be used to cover and coat different objects. Thus, the surface is constantly covered with the active agent until the object is mechanically worn away.
Claims10
An object comprising an antimicrobial surface, wherein the antimicrobial surface comprises an antimicrobial composition, the antimicrobial composition comprising:
- 1-30 parts by weight an active agent that reduces a spread of pathogens, wherein the active agent is mixed with 20-50 parts by weight of a water-soluble polymer and 5-50 parts by weight of a hydrophobic polymer, in order to produce a mixture in which the polymer forms a continuous phase, from which the active agent is released,
- wherein, upon repeated contact with a second object comprising an amount of moisture, the antimicrobial surface both wears mechanically and dissolves to release the active agent as the antimicrobial surface becomes thinner, and
- wherein the object comprises a fomite capable of contact with human skin.
