FIELD: personal usage items.

SUBSTANCE: invention relates to skin-contacting elements intended for use with hair removal razor cartridges. Shaving cartridge for removing hair comprises a body and at least two or more razors forming a blade shaving plane and a skin contacting member. Skin-contacting member comprises a container having a base and at least one wall extending vertically to a maximum height (h) from 0.1 mm above the razor plane to 0.6 mm below the razor plane (P) and a skin-contacting surface. Latter contains a metering hole and a lubricant located inside the container. Lubricant comprises a polyethylene oxide-based polymer having an average molecular weight of 0.5 to 10 million. Polyethylene oxide based polymer and the container wall maximum height (h) are selected so, that the ratio between said molecular weight of said polyethylene oxide-based polymer and said maximum height of said wall was represented by a region below the line according to the formula: polyethylene oxide molecular weight (millions) = 10*h (mm) +7.

EFFECT: invention claim provides the achievement of a technical result consisting in improving the usability due to improving of the lubricant characteristics while ensuring its delivery throughout the entire shaving cartridge usage cycle.
