| actif naturel | natural asset |

| adjuvant actif | active additive |
| adsorption sur le charbon actif | carbon adsorption |
| agent tensio-actif | surfactant |
| agent tensio-actif | surface-active agent A substance that, when used in small quantities, modifies the surface properties of liquids or solids. A surface-active agent reduces surface tension in a fluid or the interfacial tension between two immiscible fluids, such as oil and water. Surfactants are particularly useful in accomplishing the wetting or penetration of solids by aqueous liquids and serve in the manner of detergent, emulsifying, or dispersing agents. They are more effective than soap in certain situations and are used by conservators for such purposes as cleaning, wetting, and dispersing |
| aérosols radio-actifs | radioactive aerosols |
| charbon actif | activated carbon A powdered, granular or pelleted form of amorphous carbon characterized by a very large surface area per unit volume because of an enormous number of fine pores |

| composé tensio-actif | surface active compound |
| composé tensio-actif | surface active compound Any soluble substance composed of two or more unlike atoms held together by chemical bonds that reduces interfacial tension between liquids or a liquid and a solid, often used as detergents, wetting agents and emulsifiers |
