  • Patent number: 11090234
    Abstract: Provided is a product exhibiting good bubbles even from a screen foamer composition using a non-ionic surfactant. This foam contains a non-ionic surfactant and is composed of an air layer and a bubble shell encapsulating the air layer. The bubble shell has a high light transmission region which is optically transparent and a low light transmission region which is less optically transparent than the highlight transmission region, both regions being disposed so as to spread across a surface of the bubble shell in such a manner as to form an identifiable boundary therebetween; and when the foam is allowed to stand at 25° C., an area of the low light transmission region occupying the surface area of the bubble shell expands over time, and thus the entire surface of the bubble shell becomes occupied by the low light transmission region.
