A foaming agent is a material that facilitates formation of foam. The term refers to either:
- A surfactant, which, when present in small amounts, reduces surface tension of a liquid (reduces the work needed to create the foam) or increases its colloidal stability by inhibiting coalescence of bubbles or
- A blowing agent, which is the gas that forms the gaseous part of the foam.

“... in doing our psychology, we want to attribute mental states fully opaquely because it’s the fully opaque reading which tells us what the agent has in mind, and it’s what the agent has in mind that causes his behavior.”
