ABSTRACT:
A novel fast drying stable pituitous powder suspension in an alcoholic/aqueous medium having a high alcohol content and a low water content, 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 the preparation of viscous liquid, semi-solid or solid suspension products such as creams or sticks, more specifically, roll-ons or stick deodorants and medicated lotions which may also be pump activated. 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. Sodium or potassium bicarbonate suspensions have been found to be less irritating to the body and dry faster than bicarbonate solutions because the bicarbonate is delivered as a powder to be activated by body moisture.
