Emulsifiers and Wetting Agents

Emulsifiers and wetting agents (detergents and/or surfactants) are composed of anionic, cationic, or nonionic detergents, metal soaps, polyamines, and tall oils or fatty acids [28]. They facilitate the formation of a stable dispersion of insoluble liquids in water (invert-emulsion). Wetting agents are used to ensure that the solids in mud 

Base fluids (BFs) represent the major ingredient of nonaqueous drilling mud systems. They act as the continuous phase in OBMs and SBMs. Oil-based fluids (OBFs) such as diesel and mineral oils have been replaced with synthetic-based fluids (SBFs) because of the deleterious environmental hazards of OBMs. The SBFs contain fatty adds which are usually derived from vegetable oil (e.g., palm oil) or fish oil. SBFs usually constitute about 50-90% by volume of the fluid portion of the SBM [27] and about 20-40 % of the mass of the mud [35]. Ethers, esters, acetals, polymerized olefins (poly-a-olefins, linear a-oleftns, and internal olefins), enhanced mineral oils, and paraffins are used most frequently as SBFs (Table 11.2) in mud formulations [8, 36, 37].

These include liquid paraffin (contraindicated if there is any risk of aspiration), and docusate sodium which is an emulsifying and wetting agent. 

The term aerosol is also applied to some forms of detergents, emulsifiers and wetting agents. 

Aerosols are colloidal systems with gas(air) as surrounding medium. Eg smoke, fog or mist. Smoke is used in chemical warfare, as in shells and for producing smoke screensl The term aerosol is also applied to some forms of detergents emulsifiers and wetting agents.

Brij [ICI]. TM for a series of emulsifiers and wetting agents developed for use in emulsions of high alkalinity or acidity. They are polyoxyethylene ethers of higher aliphatic alcohols. Soluble in water and lower alcohols. Insoluble in coal tar hydrocarbons. 

A surfactant, emulsifier and wetting agent, sodium laureth sulfate is not the same as sodium lauryl (or dodecyl) sulfate, with which it is sometimes confused. It degreases the skin, emulsifies fats and holds skin impurities in suspension.
