Criteria used to assess the spreadability of formulations

Score	Description
−2	Formulation appears as a solid state, which cannot be spread around the application site.
−1	Formulation has to be applied with force greater than normal to achieve a desirable spread.
0	Formulation displays good spreadability with desirable stay-on semisolid property.
1	Formulation displays good spreadability with a slight tendency to flow over the skin surface.
2	Formulation has low viscosity with high tendency to flow over the skin surface.
