SODIUM LAURYL SULPHATE AND SODIUM LAURYL ETHER SULFATE
[EIRI/EDPR/1557] J.C. 352
INTRODUCTION
The sodium salts are familiar as pastes with about 30 percent of active material as dried extruded material, dried flakes or tray-dried powder all of high concentration. For special purposes as for examples as a foaming agent and detergent in tooth-pastes free, unsulphated alcohol is undesirable because of the flavour it imparts. For same exceptional cases sodium sulphate is unwanted. Sodium sulphate can be eliminated by dissolving out the sodium lauryl sulphate with hot ethyl alcohol or isopropyl alcohol. These solvents also take the free unsulphated alcohol into solution and after evaporating off the solvent a final extraction with acetone will dissolve the free alcohol and leave purified alkyl sulphate as the residue.
Some laury sulphate is described as a mixture of normal primary alkyl sulphates chiefly sodium lauryl sulphate, containing not less than 58% w/w of total alcohols. It is very soluble in water in which it forms turbid solutions, partly soluble in 95% per cent alcohol, sodium chloride and soidum sulphate together not less than 10% w/w when estimated by specified methods of analysis, unsulphated alcohol when estimated by a specified method not more than 4 per cent w/w.
Sodium lauryl sulphate (CH3(CH2)10.CH2OSO3Na) mainly used as a surfactant and foaming agent, find use in dental creams shampoos and cosmetic emulsions in general now it is manufactured through synthetic as well as natural lauryl alcohol(taking it as the starting point). Further, whole two types of the products are being manufactured in the solid form, there is demand for the material in the form of a solution also.
Sodium lauryl ether sulphate is also known as "Fatty alkyl ether sulphate". Before the discovery of sodium lauryl ether sulphate, all the detergents and shampoo manufacturers use only sodium lauryl sulphate as a raw material in the field of detergent and shampoo. Detergent and shampoos are compounds which are used for human comfort, cleanliness and for industrial surface applications. Their action is based on colloidal chemistry principles as follows:
The grease is pulled away from the surface to be cleaned by the "Key" mechanism. The success of any cleaning agent is to supply compounds with hydrophobic and hydrophyllic groups which will also appreciably decrease surface tension and increase vettability. If we classified the cleaning compound, the nature of classification comes to two steps:
1. Soap
2. Detergent
SOAP
Compounds of the type R.COO.M whre R.COO is fatty acid radical representing obelic, steani, palmitic lauric and myristic. These are usually present in soaps as mixtures based on glyceride raw materials. M is an alkali element such as Na & K.
DETERGENT
As we know that detergent is a synthetic organic chemicals which promote better surface tension lowering than soaps. These are discussed here because of the competitive position with soaps. Sodium lauryl ether sulphate play an important role with the composition of liquid detergents.
Where the use of detergents increases to the point of creating problems in municipal sewarage plants due to excessive forming and inability to reduce the organic content of the sewage effluent, biodegradation of detergent compounds with sodium lauryl ether sulphate becomes an important factor. In the U.S. detergents compounds which can be oradised to simple end-products such as methane, are known as biologically soft syndets and are preferred in detergent compounding. Those compounds which are not degradable are called bio-hard.
