1. Field Of The Invention
The present invention relates to insect repellent compositions. More particularly, the present invention relates to substantially anhydrous insect repellent compositions that are also water resistant/waterproof, as well as sweat resistant sweatproof. The composition may also provide ultraviolet (UV) sunscreen protection from both UVA and UVB radiation. As used herein, the term “insect” is intended to mean any insect or arachnid.
2. Description of the Prior Art
All percentages set forth herein are percentages by weight of the total composition unless otherwise specified.
The present invention provides a substantially anhydrous composition that offers insect repellency and, preferably, sunscreen protection. The term “substantially anhydrous” means that the composition preferably contains less than 3 wt % water or, more preferably, less than 1 wt % water. Most preferably, a composition according to the present invention contains no water.
In a first embodiment of the present invention, the insect repellent or repellent active is combined with a non-volatile solvent to provide instantaneous availability of the insect repellent, as well as an immediate, continuous, even film on the skin to provide uniform coverage over the peaks and valleys of the skin surface. In a second embodiment of the present composition, there is provided the insect repellent, a volatile solvent, and, preferably, a film former. This aggregate composition also provides instantaneous availability of the insect repellent, as well as a continuous, even film that uniformly covers the skin. A possible third embodiment useful for achieving the benefits of the present invention is the combination of the first and second embodiments, namely the insect repellent, the non-volatile solvent, the volatile solvent, and, optionally, a film former.
