Definition

role of a material entity when it is used, or planned to be used, to lower the surface tension of a medium or the interfacial tension between phases by preferentially adsorbing at liquid-vapor or other phase interfaces

Explanatory Notes

The term medium refers broadly to a surrounding phase system, such as a liquid, gas, or solid, not only to culture medium. Materials bearing a surfactant role are used to promote wetting, dispersion, emulsification, foam control, or cleaning by reducing surface or interfacial tension. A material bearing this role may be a single compound or a formulated mixture.

Examples

• Role borne by polysorbate 80 when added to culture medium to improve wetting and dispersion; Role borne by Sodium dodecyl sulfate when added to aqueous buffer to reduce interfacial tension

Primitive Class

This class is declared primitive and it does not have necessary and sufficient condiftions defined.

Primitive Rationale

There are insufficient constructs to create a set of necessary and sufficient conditions

Formal Axioms

First-Order Logic Axioms

SurfactantRole(x) → Role(x) ∧ ∃m (MaterialEntity(m) ∧ roleOf(x, m))

Semi-Formal Natural Language Axioms

if x is a ‘surfactant role’ then x is a ‘role’ that is the ‘role of’ some ‘material entity’
