Abstract
Compositions and methods for producing colored bubbles, having a single color uniformly dispersed in the film, are described. The composition comprises at least one surfactant mixed with at least one colorant, the colorant forming at least approximately 10% of the composition. The surfactant, or surface-active agent, forms the bubble while the colorant, or pigment, provides the color. Generally, the composition may comprise 10-99% colorant to produce varying degrees of opacity. In addition, glycerin, fragrance, propylene glycol, sodium lauryl sulfate, potassium hydroxide, or other additives may be included.
