GENERAL DESCRIPTION & APPLICATIONS

Nonionic surfactants are surface active agents which do not dissociate into ions in aqueous solutions, unlike anionic surfactants which have a negative charge and cationic surfactants which have a positive charge in aqueous solution. Nonionic surfactants are more widely used as detergents than ionic surfactants because anionic surfactants are insoluble in many hard water and cationic surfactants are considered to be poor cleaners. In addition to detergency, nonionic surfactants show excellent solvency, low foam properties and chemical stability. It is thought that nonionic surfactants are mild on the skin even at high loadings and long-term exposure. The hydrophilic group of nonionic surfactants is a polymerized alkene oxide (water soluble polyether with 10 to 100 units length typically). They are prepared by polymerization of ethylene oxide, propylene oxide, and butylene oxide in the same molecule. Depending on the ratio and order of oxide addition, together with the number of carbon atoms which vary the chemical and physical properties, nonionic surfactant is used as a wetting agent, a detergent, or an emulsifier. 

HLB (Hydrophilic-Lipophilic Balance) values for proper applications.

<10 : Lipid soluble (or water-insoluble)
>10 : Water Soluble
4-8 : Antifoaming
7-11 : Water-in-oil emulsion
12-16 : Oil-in-water emulsion
11-14 : Good Wetting
12-15 : Good detergency
16-20 : Stabilizing

Nonionic surfactants include alcohol ethoxylates, alkylphenol ethoxylates, phenol ethoxylates, amide ethoxylates, glyceride ethoxylates (soya bean oil and caster oil ethoxylates), fatty acid ethoxylates, and fatty amine ethoxylates. Another commercially significant nonionic surfactants are the alkyl glycosides in which the hydrophilic groups are sugars (polysaccharides).

Fatty alcohol ethoxylates, clear to yellowish liquid to waxy solids depending on alkyl chain length and the number of ethoxy groups, are non ionic surfactants which contain both hydrophobic tail portion (fatty alcohol part) and hydrophilic polar head groups (ethoxy chain part), and are thus tend to dissolve in both aqueous and oil phase and to reduce the surface tension of liquids. Ethylene oxide (also called epoxyethane and oxirane) is the simplest cyclic ether or epoxide, with the formula C2H4O; reactive material which is added to the base of alcohols (or amines) to form ethoxylated surfactants. The Hydrophilic-Lipophilic Balance (HLB) of EO surfactant is related to the hydrophilic portion of the molecule. More hydrophilic groups enable more solubility in water as more hydrogen bondings exist. They are non-ionic in solution which has no electrical charge, which means well-work in hard water at low temperatures as well as stability in acid and alkali solution and compatibility with other surfactants. Generally, surfactant's name are formed by adding the mole number of ethylene oxide. There is a wide HLB range depend their molar ratios between fatty alcohol and E.O. The very low (2, 2.5 or 3) mole ratio products are used to prepare SLES (sodium lauryl ether sulfate) which is used as a foaming and cleansing agent for shampoos and cleansers, suited for high viscosity products and low pH products. Slightly higher mole ratio products are used as wetting agent. The E.O surfactants of 7-12 moles ratio with alcohol are suitable for detergent application. Higher moles ratio products are emulsifiers. Their 3 representative functions are as wetting agent, detergency and emulsifier.

End applications include;

Detergents and Industrial Cleaners, Dispersants, Stabilizers, Sanitizers, Defoaming Agents. Agrochemical Emulsifiers, Metal Working, Textile Processing, Paper De-inking, Drilling Products Intermediate Anionic Surfactants Synthesis, Dust Control, Adhesive, Plastic Industry, Lube Oil, Cosmetic and Pharmaceuticals.
