Abstract

PURPOSE: To allow the reuse of a solid shaving aid consisting of a water-soluble cellulose deriv. which gives rise to a thermal gelatinization phenomenon by fixing the shaving aid to the exposed part of a razor head. CONSTITUTION: The solid shaving aid 8 of a thin strip shape is fixed onto the front end 7a near the edge 6a of an upper blade body 6. The shaving aid 8 consists of hydroxypropyl cellulose. The hydroxypropyl cellulose has the nature that while it is soluble in cold water, it becomes insoluble in hot water by giving rise to the thermal gelatinization phenomenon and restores the original state when cooled. Even when the razor is inadvertently carried to a place having steam, for example, a sauna or the like or is inadvertently dropped into the hot water of a bath room or the like, the dissolving and peeling of the solid shaving aid 8 do not arise any more and the reuse of the solid shaving aid 8 is possible.

In this example, since such cellulose derivatives (bitroxypropyl cellulose, methyl cellulose, hydroxypropyl methyl cellulose) are used as the shaving aid 8, the shaving aid 8 can reduce the water temperature to below the above-mentioned gelation salinity. However, when the temperature rises above the gelling temperature, it undergoes a thermal gelation phenomenon and becomes insoluble, changing from transparent to white during gelation. Therefore,
Even if you carelessly bring the razor into a place with steam, such as 1±una, or accidentally drop it into hot water such as a bathroom, it will not work.
The solid shaving aid 8 on the razor head 1 will no longer melt and peel off.
