The present invention relates to wet wipes (1) for use in wiping surfaces in the home and in industry in addition to their use on the human body such as for baby wipes, make-up removal and other skin care applications. The wet wipes are provided with an improved leading edge (2), which can be readily identified grasped and separated from the wet wipe (1) stack by the consumer. This is achieved by reducing the coefficient of friction of at least one surface of the substrate of the wipe (1) so as to reduce the adhesive forces between adjacent surfaces of the wipes.

Why it's free to use
- Filed February 5, 1998 and granted July 8, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 5, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 5, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
