Suspensions of solid particles of colloidal size in liquids are called sols. Suspensions of either solid or liquid particles in a gas are called aerosols. Emulsions are suspensions of liquid droplets in a second liquid. Foams are suspensions of liquid droplets in either a liquid or a solid. For both emulsions and foams the suspended particles are frequently substantially larger than the usual colloidal range and also, in the case of foams, the continuous medium is often so thin as it surrounds the gas bubbles as to be itself in the colloidal state.  4, fiche 1, Anglais, - sol

Des particules qui portent elles-mêmes une charge électrique (ions) ou des charges partielles, attirent les molécules d'eau et s'entourent d'une enveloppe hydratée. Les protéines forment ainsi une solution colloïdale. Lorsqu'elles perdent de l'eau, cette solution appelée sol devient gélatineuse et s'épaissit.  2, fiche 1, Français, - sol

Oil slick dispersants. When oil ... is treated with a suitable surface active agent and agitation applied, the oil is broken up into particles ... so small that they constitute an oil-in-water emulsion ... Dispersants serve to increase the surface area of an oil spill and disperse oil globules throughout the layer volume water. This causes an accelerated degradation of oil by microbiological action.  7, fiche 2, Anglais, - dispersant

Record number: 2, Textual support number: 1 OBS

The chemicals used to disperse the oil are emulsifiers. Although a chemist would never confuse the terms dispersant and emulsifier, the former designating a product which encourages the distribution of finely divided solids in a fluid, either liquid or gas, the latter referring to a product which encourages the colloidal dispersion of one liquid in another, the terms are synonymous in the field of oil pollution control. This is explained by the following sentence taken from "The Control of oil pollution on the sea and inland waters", edited by J. Wardley-Smith(source COCOB) :"It was found... [that the product] when sprayed on to the oil, effectively softened and dispersed it by means of emulsification... "The dispersion is accomplished by products which emulsify the oil, i. e., emulsifiers. Dispersion is used in its general sense and hence dispersant simply means a product that causes spreading. Also dispersant is used more frequently than emulsifier.  8, fiche 2, Anglais, - dispersant
