Open the CIPO recordAbstract From the Canadian patent
Cleaning products are disclosed which incorporate an increased amount of cationic compounds in or on the fibrous matrix of the substrate which allow the product to bind and remove various microbes and contaminants from the surface of skin. The products disclosed herein do not necessarily kill microbes on the skin's surface, but dislodge and bind the microbe through electrostatic interactions between the product and the microbe and allow the microbe to be removed by a positively charged substrate.

Why it's free to use
- Filed May 6, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 6, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 6, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
