Abstract
A film forming composition including a film forming substance having amphiphilic molecules and being dispersed in a gel-like carrier having a non-liquid state below about 20.degree. C. The carrier stabilizes the film forming substance, and inhibits diffusion of moisture and oxygen into the composition. This minimizes deterioration of the film forming substance, and also minimizes undesirable formation of agglomerations of such substance. When the composition is applied to a surface, an ultra thin substantially continuous film of substantially uniform thickness forms spontaneously and attaches to the surface. The excess composition is then washed away.
