1. Field of Invention
This invention relates to shaving compositions, which are applied to the skin to facilitate shaving.
2. Background Art
Shaving compositions have been available for decades in a variety of forms including bars, sticks, creams, lotions, and foams (both aerosol or non-aerosol). Such compositions or gels provide a form of lubrication to the shaving surface prior to shaving, to reduce friction, and may also offer a level of skin protection, nourishment, healing, and moisturization.
After shaving, the razor is usually rinsed, in order to wash the conventional shaving composition off the blade or blades.
In one aspect invention provides a shaving composition which is magnetic.
In another aspect the invention provides a shaving composition containing ferromagnetic particles.
In another aspect the invention provides a shaving composition containing magnetic iron oxide or magnetite (Fe3O4).
When applied to the shaving surface, the razor will come in contact with the shaving composition and a proportion of the composition will be retained on the razor blade(s) due to the magnetic nature of the blade(s). The resulting coating of shaving composition on the surface of the blade(s) serves as a thin film coating which is retained until the razor is next used, protecting the blade(s) from the primary cause of deterioration, being oxidation, and ensuring that an additional level of lubrication is immediately available already on the blade ready for its next use.
It thus becomes possible to provide a shaving composition or gel which not only protects, nourishes, and moisturizes the skin being shaved (shaving surface) but also protects the razor and reduces the rate of deterioration and erosion due to the shaving action and the atmosphere.
The shaving composition may be based on any conventional shaving composition (whether liquid, flowable, or spreadable), with the addition of a suitable amount of ferromagnetic particles.
Any suitable ferromagnetic particles may be used, for example iron oxide or chromium dioxide.
The minimum content of ferromagnetic particles is determined by the need to provide a significant magnetic effect and may, for example, be at least about 0.01 wt. %, preferably at least about 0.02 wt. %, more preferably at least about 0.03 wt. %. The maximum content is limited by the desired physical properties of the composition, such as viscosity, translucence, and color. For example, the content of ferromagnetic particles may be at most about 1 wt. %, preferably at most about 0.5 wt. %, more preferably at most about 0.1 wt. %. The content is preferably kept low in order to avoid discoloration of the composition, particularly by iron oxide.
The composition is preferably in the form of a colorless translucent or transparent gel.
Suitable compositions are water-based compositions containing oils and surfactants.
The composition is preferably neutral.
