Abstract
An emulsifier-free lotion suspension of at least one liquid in another liquid, the lotion having high intrinsic stability. The lotion is prepared by combining microscopic particles of soft, porous, frangible polymer material containing at least a first liquid with a second liquid in free form. The amount of free liquid is sufficient to achieve a creamy texture without allowing bouyant movement of the particles. The softness of the particles is sufficient to enable the lotion to leave essentially no visible residue when rubbed onto the skin. The polymer material preferably takes the form of a microporous cellulosic powder.
