Abstract

Novel curable compositions are disclosed which include a water insoluble antimicrobial agent. The curable compositions are useful in inhibiting the growth of bacteria on the surface of the curable composition, within the curable compositions and in a volume adjacent to the curable composition.

Claims

1. An artificial fingernail composition, comprising:

a polymerizable system and a water-insoluble anti-microbial agent inert to the polymerizable system, wherein said composition is cured to produce an artificial fingernail.

3. The artificial fingernail of claim 1 wherein said water insoluble antimicrobial agent is selected from the group consisting of halogenated diphenyl ethers, halogenated salicylanilides, benzoic esters, halogenated carbanalides and phenolic compounds.

4. The artificial fingernail of claim 1 wherein said water insoluble antimicrobial agent is triclosan.

5. The artificial fingernail of claim 4 wherein said triclosan is present in an amount of 0.3% by weight of non-volatile solids.

6. The artificial fingernail of claim 4 wherein said triclosan is present in an amount of 1.0% by weight of non-volatile solids.

2. An artificial fingernail comprising a cured polymerization system and a water-insoluble anti-microbial agent inert to the polymerization system, wherein said anti-microbial agent provides a zone of inhibition of growth of bacteria surrounding said artificial fingernail.
