Abstract
A condom comprises, on one or more surfaces thereof, a self-lubricating coating comprising a dry powder having a particle size of 300 microns or less. The self-lubricating coating becomes lubricious when the coating comes into contact with a liquid environment. A method of making a self-lubricating condom comprises providing a dry condom and coating said condom, on one or more surfaces thereof, with a self-lubricating coating comprising a dry powder. The invention also provides the use of a dry powder such as xanthan gum to provide a self-lubricating coating for a condom.
