| Not applicable | Surfactants | http://en.wikipedia.org/wiki/Surfactants Product Info: 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). 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 (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 nonylphenol and E.O. The common mole ratio forms for detergency are NPE 9 - 12, where the number indicates ethoxylate chain length. The lower number mole ratio products are used as wetting agent whereas the higher moles ratio products are emulsifiers and solubilizer. Nonylphenol ethoxylates features excelent emulsifying and high detergency properties.

LAS is an anionic surfactants with molecules characterized by a hydrophobic and a hydrophilic group. Alpha-olefin sulfonates (AOS) alkyl sulfates (AS) are also examples of commercial anionic surfactants. They are nonvolatile compounds produced by sulfonation. LAS are complex mixtures of homologues of different alkyl chain lengths (C10 to C13 or C14) and phenyl positional isomers of 2 to 5-phenyl in proportions dictated by the starting materials and reaction conditions, each containing an aromatic ring sulfonated at the para position and attached to a linear alkyl chain at any position with the exception of terminal one (1-phenyl). The properties of LAS differ in physical and chemical properties according to the alkyl chain length, resulting in formulations for various applications. The starting material LAB (linear alkylbenzene) is produced by the alkylation of benzene with n-paraffins in the presence of hydrogen fluoride (HF) or aluminium chloride (AlCl3) as a catalyst. LAS is produced by the sulfonation of LAB with oleum in batch reactors. Other sulfonation alternative reagents are sulfuric acid, diluted sulfur trioxide, chlorosulfonic acid and sulfamic acid on falling film reactors. LAS are then neutralized to the desired salt (sodium, ammonium, calcium, potassium, and triethanolamine salts). Surfactants are widely used in the industry needed to improve contact between polar and non-polar media such as between oil and water or between water and minerals. Linear alkylbenzene sulfonic acid is mainly used to produce household detergents including laundry powders, laundry liquids, dishwashing liquids and other household cleaners as well as in numerous industrial applications like as a coupling agent and as an emulsifier for agricultural herbicides and in emulsion polymerization. Ionic surfactants which contain hydrophobic hydrocarbon group connected with one or several hydrophilic groups dissociate into a positively charged cation and a negatively charged anion in an aqueous solution. If the head is negatively charged to carry the surface active properties, it is called anionic surfactant, whereas a positively charged head is the carrier of the surface active properties in cationic surfactants. Typically cationic surfactants are based on the nitrogen atom carrying the cationic charge such as amine and quaternary ammonium product. Cationic surfactant is considered to be poor cleaners but it contributes to the fabric softening, the disinfecting properties, and the grease-water interfacial tension reducing. Cationic surfactants include quaternary ammonium compounds, amines (primary, secondary, tertiary, diamines, polyamines, amine salts), imidazoline compounds, betaine compounds, and esterquats. Anionic surfactant is the widely used type of surface active agent for laundry detergents, liquid cleaners and shampoos due to excellent cleaning properties particularly effective at oily soil cleaning and oil/clay soil suspension. Anionic surfactants are deactivated in many hard water. To prevent deactivation, builders should be dosed. Anionic surfactant is used as a emulsifier in cosmetics, tooth paste, cream, shampoo, and acrylic binder. Common soap is an anionic surfactant. Carboxylate, sulfate, sulfonate and phosphate are the polar groups in anionic surfactants. Anionic surfactants include alkyl benzene sulfonate, fatty acid salts, sodium lauryl sulfate, alkyl sulfate salts, sodium lauryl ether sulfate, alpha-olefin sulfonates, phosphate esters, sulphosuccinates, alkyl phenol ether sulfates, and isethionates. order / more information... |
