Drainin

Drainin is a fictional chemical compound referenced in science fiction and worldbuilding contexts as a specialized agent to promote drainage and fluid management. It is not an established material in real-world chemistry. The name combines drain with the chemical-suffix convention -in, a pattern often used for imagined substances.

In its in-universe description, drainin is portrayed as a small organic molecule designed to modify interfacial properties and reduce resistance to flow in narrow channels and porous media. It is typically described as a surfactant-like agent with amphiphilic structure, capable of lowering liquid retention on certain surfaces and easing capillary bottlenecks. Some depictions assign drainin activation to external cues such as light or temperature change, enabling controlled drainage on demand.

Fictional properties commonly attributed to drainin include stability at ambient conditions, compatibility with common solvents, and low reactivity with metals. In many stories, its production is said to involve secretive multi-step syntheses carried out by corporate or research institutions, with access tightly controlled and currency or supply posing plot tensions. Its fictional applications span plumbing systems in space habitats, microfluidic diagnostic devices, and large-scale wastewater-treatment simulations within the imagined world.

Note: drainin does not exist as a real chemical substance. References outside fiction may indicate confusion with real surfactants or drain-cleaning products. In the real world, drain cleaners rely on caustic, oxidizing, or enzymatic chemistries and should be used according to manufacturers’ instructions.
