A problem exists, however, in relieving the skin irritation which frequently develops in situations in which a area of the skin is enclosed for extended periods of time. This most frequently occurs with casts which enclose areas of the skin for varying extended periods of time necessary for broken bones to heal. Due to the nature of the normal or traditional cast, the affected skin area remains enclosed within the cast for extended periods during the healing process. Moisture from the skin builds up over time, resulting in a skin irritation or "itching" sensation and at times an unpleasant smell or odor. Prior attempts or methods of eliminating the "itching" sensation within a cast have been limited to the shaking or sprinkling of a dry talc powder or corn starch down the cast in an effort to cause the powder to reach the irritated skin area or attempting to scratch the "itching" area by inserting thin elongated elements down the cast. These methods of alleviating the "itching" sensation have proven to be ineffective.

A problem frequently experienced by individuals who are required to wear a cast or other semi-permanent, non-removable enclosure over a portion of their body is the development of an "itching" sensation or irritation on the skin within the cast. This sensation is the result of moisture accumulation, normally through perspiration, within the cast, which moisture is not readily evaporated or dried from the skin due to the particular area of the skin being enclosed within the cast. The enclosure of the skin area by the cast prohibits the circulation of air over the skin area to assist in the evaporation of the moisture.

The Cast Calm spray ™ comprises the novel application of an anti-moisture mixture within a cast by means of an aerosol spray. In this form the anti-moisture mixture is applied as a liquid slurry within the area enclosed by the cast. The mixture is applied to the area which is experiencing the "itching" sensation under pressure via a traditional aerosol dispenser utilizing an elongated flexible applicator nozzle to enable the anti-moisture mixture to be applied within the confines of a cast.
