ABSTRACT:
A novel stable pituitous bicarbonate suspension in an aqueous/alcoholic medium having a high alcohol content and a low water content, with substantially no bicarbonate in solution, containing hydroxyethyl cellulose as the essential suspending agent, said alcohol content exceeding the upper solubility of hydroxyethyl cellulose in said alcohol and the water content being sufficient to prevent precipitation of said suspending agent and at least 5% by weight; having utility in deodorant products such as roll-ons, pumps and on substrates such as deodorant pads. The concentration of sodium or potassium bicarbonate is preferably high, about 10%, however 1-20% may be used. The alcohol utilized herein is monohydric such as ethanol, methyl or isopropyl alcohol, however, a polyhydric alcohol such as propylene glycol, glycerine and/or polypropylene glycols may be partially substituted for the monohydric alcohol. The bicarbonate suspensions have been found to be less irritating to the body and dry faster than the bicarbonate solutions because the bicarbonate is delivered as a powder to be activated by body moisture.
