Abstract:
A skin engaging member for a razor cartridge includes an erodible first layer and an erodible second layer below the first layer. Each layer includes a lubricious water soluble polymer and can include a water insoluble polymer. The second layer includes a fragrance that can be in the form of microcapsules or a suitable additive of the polymeric material(s). As the first layer erodes during normal use of the razor cartridge the second layer is eventually exposed dissolving or fracturing the microcapsules or otherwise releasing the fragrance. The fragrance is malodorous indicating to e.g. a vision impaired user that the optimal life of the razor cartridge is at or nearing its end. The first layer can also be provided with a non-malodorous fragrance. A third erodible layer can be provided between the first and second layer and can also include a fragrance. End-of-optimal-life indication can be rapid or gradual.
