Abstract

Flowable, highly water soluble discrete particle disinfecting composition of chlorhexidine are provided. The composition is powdery in nature and makes chlorhexidine suitable for a general use, all purpose disinfectant for veterinary uses. It is comprised of a substrate of polyhydric alcohol coated with an encapsulating effective amount of a compatible surfactant, followed by a thin disinfecting coating of chlorhexidine.

Claims

1. A dry flowable, water dispersible, discrete particle disinfecting composition comprising:

a water soluble, flowable, solid polyhydric alcohol substrate encapsulated in a compatible surfactant; and

coated with chlorhexidine.

2. The composition of claim 1 wherein the surfactant is a nonionic surfactant.

3. The composition of claim 2 wherein said surfactant is a fatty alcohol ethoxylate.

4. The composition of claim 1 wherein the polyhydric alcohol is sorbitol.

5. The composition of claim 1 wherein the chlorhexidine is in the form of chlorhexidine diacetate.

6. The composition of claim 1 wherein the polyhydric alcohol is within the range of from about 48% by weight to about 68% by weight of said composition.

9. The composition of claim 6 wherein the polyhydric alcohol is within the range of from about 53% by weight to about 63% by weight of said composition.

7. A dry, flowable, water dispersible, discrete particle disinfecting composition comprising:

a water soluble, flowable, solid polyhydric alcohol substrate encapsulated in a compatible surfactant; and

coated with from about 10% by weight to about 30% by weight of chlorhexidine.

8. The composition of claim 7 wherein the amount of chlorohexidine is from about 15% by weight to about 25% by weight.
