The present invention features a disposable razor cartridge unit or disposable razor system having a shaving aid in the form of a comfort strip mounted on a razor head, wherein the comfort strip is acidified so that the strip does not become stringy upon exposure to a basic material. A water-soluble acid or a combination of an acid and other materials may be used to reduce the pH level from that of standard, non-acidified comfort strip. In a preferred embodiment, the comfort strip contains up to 5 % of a water-soluble acid such as citric acid. |
