The applicator is made from a porous and compressible cellular material such as an open-cell foam (20) with a surface of open cells having their edges (25) on the applicator surface (21) and a coating of flock fibres (30) made from cotton, cellulose or synthetic materials. The foam can have hydrophilic or lipophilic properties and can incorporate a hydroabsorbent component or biocidal agent. |
