Liquid antimicrobial comprising a water-soluble polymer and a water-soluble antimicrobial agent
This invention relates to a liquid antimicrobial composition comprising: (a) water, (b) a water-soluble polymer, and (c) at least one water-soluble antimicrobial; as well as to an item of clothing, a curtain, a blind, an item of bedding, wallpaper or laundry product comprising the water-soluble polymer and the at least one water-soluble antimicrobial. This invention also relates to a method of preparing the liquid antimicrobial composition comprising the step of mixing water, a water-soluble polymer, and at least one aqueous solution of a water-soluble antimicrobial.
1. A liquid antimicrobial composition comprising:
(a) water;
(b) a water-soluble polymer; and
(c) two water-soluble antimicrobials,
wherein the water-soluble polymer is polyvinyl alcohol,
wherein the polyvinyl alcohol is 85-93% hydrolysed, and
wherein the two water-soluble antimicrobials are benzalkonium chloride and didecyldimethylammonium chloride.
2. The liquid antimicrobial composition as claimed in claim 1 , comprising:
(a) 50-60 wt % of the water;
(b) 3-7 wt % of the water-soluble polymer; and
(c) 35-45 wt % of the two water-soluble antimicrobial.
3. The liquid antimicrobial composition as claimed in claim 1 , wherein the polyvinyl alcohol is 86-89% hydrolysed.
4. The liquid antimicrobial composition as claimed in claim 1 , comprising 15-20 wt % benzalkonium chloride and 19-23 wt % didecyldimethylammonium chloride.
5. A method of preparing a liquid antimicrobial composition as claimed in claim 1 , the method comprising the step of mixing water, a water-soluble polymer, and at least one aqueous solution of two water-soluble antimicrobials.
6. A method of applying a liquid antimicrobial composition as claimed in claim 1 to an absorbent material, the method comprising the step of contacting the absorbent fabric with the liquid antimicrobial composition.
7. An item of clothing, a curtain, a blind, an item of bedding, wallpaper or laundry product comprising a water-soluble polymer and at least two water-soluble antimicrobials as claimed in claim 1 .
