Meanings
Adjective
describing a chemical or biological process in which one of the products helps catalyze more of the same process
Beyond the definition
Imagine a tiny snowball rolling down a hill. As it rolls, it picks up more snow, growing bigger and faster. That's kind of like an autocatalytic process! "Autocatalytic" describes something that accelerates its own production—the product of a reaction acts as a catalyst to create more of itself. It's a bit like a positive feedback loop where things build on themselves.
This isn't just about chemistry, though! You might hear it used to describe social trends or even economic bubbles—something that gains momentum because its very success fuels further success. Think of a viral video: the more people watch it, the more likely others are to see it and share it, creating an autocatalytic spread.
"Autocatalytic" comes from the Greek roots auto- (self) and katalysis (loosening or breaking down). Originally a term in chemistry, it describes a reaction where one of the products acts as a catalyst for the same reaction. This means the reaction doesn't need continuous external input to sustain itself; it maintains its own momentum and often accelerates over time.
For example, certain chemical reactions involving organic molecules can be autocatalytic—once a small amount of product is formed, it speeds up the formation of more product. It's like setting off a chain reaction! This differs from a regular catalyzed reaction, which relies on an external catalyst that must be added to the system.
However, the concept has expanded beyond chemistry. In other fields, "autocatalytic" describes any process where the output reinforces and accelerates the input.
- Social Sciences: An autocatalytic social trend is one that gains momentum because the act of more people participating makes it even more appealing to others (think of fashion trends or meme culture).
- Economics: An economic bubble can be described as autocatalytic—rising prices attract more investment, which further drives up prices.
- Biology: Some biological processes, like protein folding, can exhibit autocatalysis where the initial formation of a correctly folded protein helps other proteins fold correctly.
While often positive (like innovation cycles), an autocatalytic process can also be destructive if unchecked, leading to runaway effects or instability. So, while it sounds complex, "autocatalytic" simply means something that fuels its own growth and continuation, creating a self-reinforcing cycle.
Examples
- 1
Chemical reaction
At first the reaction was slow, but once enough product had formed, it became autocatalytic.

Origin of life
Some scientists think early life may have depended on an autocatalytic cycle of molecules.
- Phrasean autocatalytic cycle

- 3
Business growth
The company’s growth became almost autocatalytic, with each new customer attracting more customers.
