The present invention relates to an apparatus for measuring the spreadability of semisolid formulations. Semisolid preparations such as ointments, pastes, cream emulsions, gels and rigid foams are considered as important topical pharmaceutical formulation. Their common property is their ability to adhere to the applied surface for a reasonable period before they are washed off or worn off. Semisolid preparations usually serve as vehicle for topical drug delivery, as emollients, or as protective or occlusive dressings, or they may be applied to the skin and membranes [1]. These preparations are widely used as a means to alter the hydration state of applied topical area and deliver the incorporated drugs in it [2].
