Performance of Surfactants
Surface active agents, or short Surfactants, are usually organic compounds that are amphiphilic, meaning they contain both hydrophobic and hydrophilic groups and are therefore soluble in both organic solvents and water. They reduce the surface tension of a
liquid by adsorbing at the liquid-gas interface, allowing easier spreading, and lower the
interfacial tension between two liquids, e.g. between oil and water, by adsorbing at the
liquid-liquid interface. Surfactants are used as emulsifiers, wetting agents, dispersants
and stabilizers for different chemical and industrial applications.

Alcohol ethoxylates are based on synthetic or natural fatty alcohols. Synthetic alcohols used
for ethoxylation are available from hydroformylation leading to oxoalcohols or from the
oligomerization of ethylene with Ziegler catalysts. Natural fatty alcohols are produced by
reduction of fatty acids. Both synthetic and natural alcohol ethoxylates are used as nonionic
surfactants in many industries.


Fatty amine ethoxylate are made by ethoxylation of primary fatty amines and combine
the wetting, emulsifying and dispersing properties of nonionic and cationic surfactants.
At neutral and acid conditions fatty amine ethoxylates have a positive charge, at alkaline
conditions they behave like nonionic surfactants.
Fatty amine ethoxylates are used as emulsifiers and dispersing agents for cationic wax
emulsions, as wetting agents in sanitary cleaners and crop protection products like soluble
liquids of pesticides and as antistatic agents.


Sulfonation products are anionic surfactants comprising a hydrophobic alkyl chain and an
anionic sulfonic acid group. Sulfonates are anionic surfactants which deprotonate at neutral
and acid pH values and form micelles at low concentrations. They have strong wetting and
emulsifying capabilities. Particularly olefin sulfonates form stable micro-foams used for
building and construction to entrap air in render, plasters and concrete. The micro-foam
reduces the weight of plasters and improves the temperature stability of concrete. Alkane
sulfonate and olefin sulfonates are both used as emulsifiers for emulsion polymerization.


Sulfate esters are available from sulfonation of fatty alcohols and alcohol ethoxylates. They
are strong wetting agents and emulsifiers applied in many fields of the industry including
house hold detergents. Sulfate esters are one of the most important surfactant groups in
emulsion polymerization due to their ability to form micelles under acid conditions.


Sulfosuccinates and Sulfosuccinamates are wetting agents and emulsifiers for industrial
applications. They are used as wetting agents in coatings and printing inks, as dispersing
agents and as foaming agents in textiles and carpet back sizing

Phosphate esters are mixtures of mono, di and tri-ester, free alcohol and phosphoric acid.
Only the mono and diester have a charged group within the molecule and have surface
activity and emulsifying capability. The ration of the mono, di and triester is controlling the
ability to form W/O and O/W emulsions


Phosphate esters are used as antistatic agents, extreme pressure lubricant additives, emulsifiers and dispersing agents. Alkyl phosphates are used for hydrophobic systems like W/O
emulsions and inks. Ethoxylated phosphate esters are used as emulsifiers and dispersing
agents for O/W emulsions, emulsion polymerization and dispersions. The longer the polyglycol chain of the phosphate ester the stronger is the dispersing and stabilizing effect in
the ester. 


Alkyl phosphonates consists of amphiphilic molecules with a phosphonic acid group attached
to the carbon atom of an alkyl chain. Alkyl phosphonates have a strong affinity to metal surfaces and are used as corrosion inhibitors. Another application of alkyl phosphonates is the
hydrotropic effect in surfactant formulations.
