Solid-Layered Bleach Composition Resolving Residue and Malodor

The bleach composition is divided into multiple solid layers, with calcium hypochlorite confined to specific layers (e.g., first and third layers) separated from functional ingredients like surfactants and odor absorbents in intermediate layers. This segmentation prevents direct contact between calcium hypochlorite and ingredients that would otherwise react or interfere, eliminating residue formation while maintaining cost-effectiveness.

An intermediate layer containing odor absorbent ingredients (such as activated carbon, zeolite, or clay) is positioned between the calcium hypochlorite-containing layers and other functional ingredients. This intermediary layer absorbs and traps malodors generated by calcium hypochlorite, preventing them from escaping while allowing the calcium hypochlorite to maintain its cost-effective cleaning performance.

Instead of coating or encapsulating individual ingredients, the composition uses a multi-layer solid structure where different ingredients are segregated into distinct layers. This segmentation provides inherent stability and shelf-life without requiring additional coating materials or encapsulation processes, thereby reducing complexity while maintaining reliability.

The solid-layered structure allows each layer to dissolve independently and rapidly when contacted with water or moisture. The segmented architecture eliminates the need for coating or encapsulation materials that would slow dissolution, enabling fast release of active ingredients while maintaining shelf-life through physical separation of unstable components.
