Moisturizing antimicrobial composition
An antimicrobial moisturizing composition includes benzethonium chloride or benzalkonium chloride, a non-benzyl cationic surfactant, and an aqueous carrier. The composition of the present invention provides a significant and unexpected reduction of irritation, inflammation, dryness and/or redness, all issues associated with known alcohol-based skin disinfectants. In particular, the present invention provides a stable, aesthetically-pleasing, long-lasting, and moisturizing antimicrobial composition that is substantially free of ethanol, polysorbates, and anionic compounds that are known to inhibit the activity of benzethonium chloride or benzalkonium chloride.
1. A moisturizing antimicrobial composition comprising:
from about 0.05% to about 4.0% by weight of benzethonium chloride;
from about 0.01% to about 10.0% by weight of a cationic surfactant having a molar mass of less than about 800 g/mol; and
from about 30% to about 90% by weight of an aqueous carrier, wherein said composition is substantially free of ethanol.
2. The moisturizing composition of claim 1 wherein said composition comprises from about 0.1% to 0.5% by weight of benzethonium chloride.
3. The moisturizing composition of claim 1 , wherein said cationic surfactant is a non-benzyl cationic surfactant.
4. The moisturizing composition of claim 3 , wherein said non-benzyl cationic surfactant is a fatty quaternary amine selected from the group consisting of an alkyl ammonium chloride, alkyl ammonium methosulfate, derivatives and combinations thereof.
5. The moisturizing composition of claim 3 , wherein said non-benzyl cationic surfactant is selected from the group consisting of behentrimonium methosulfate, distearyl dimonium chloride, derivatives and combinations thereof.
6. The composition of claim 1 , wherein the composition has a form selected from the group consisting of emulsions, gels, sprays, and combinations thereof.
7. The composition of claim 1 , further comprising from about 0.0001% to about 99.0% by weight of a component selected from the group consisting of anti-inflammatory agents, pharmaceuticals, and combinations thereof.
8. The composition of claim 1 , wherein said composition has a viscosity of from about 10,000 to about 1,000,000 centipoise.
9. The composition of claim 1 , wherein said composition is substantially free of polysorbates.
10. The composition of claim 1 , wherein said composition is substantially free of anionic compounds.

from about 0.01% to 20% EDTA acid;
from about 0.01% to 20% potassium chloride;
from about 0.01% to 20% methylparaben;
from about 0.01% to 20% propylparaben;
from about 0.01% to 20% dimethicone;
from about 0.01% to 20% distearyldimonium chloride;
from about 0.01% to 20% cocamidopropyle PG-dimonium chloride phosphate;
from about 0.01% to 20% glyceryl laurate;

from about 0.01% to 20% steareth-21; and
from about 0.01% to 20% cetyl alcohol.
12. A moisturizing antimicrobial composition comprising:
from about 0.05% to about 4.0% by weight of benzethonium chloride;
from about 0.01% to about 10.0% by weight of a cationic surfactant having a molar mass of greater than about 800 g/mol; and
from about 30% to about 90% by weight of an aqueous carrier,
wherein said composition is substantially free of ethanol, and wherein said cationic surfactant is a polyacrylate-1 crosspolymer.
