- This formulation will help in production of SLES.
Sodium Lauryl Ether Sulfate (a.k.a. SLES, Sodium Laureth Sulfate) is a detergent and anionic surfactant with excellent performance used in personal care products. SLES is an effective foaming agent. It appears as a white to yellowish paste. It is prepared by ethoxylation of dodecyl alcohol, followed by sulfonation and neutralization with sodium salt.
Like other fatty alcohol sulfates and fatty alcohol ether sulfates, SLES applications are basically related to surface-active properties of this compound, which contains both hydrophilic and hydrophobic portions within its molecules.
In fact, the possibility of altering those properties allows the tailoring of these compounds to be used in a broad range of applications, demanding good activity (foaming/detergency), stability over a wide pH range, water solubility, chemical compatibility, etc.
With such versatility, these chemicals are widely used as base for shampoos, liquid detergents, foaming agent for tooth pastes and mouth washes and emulsifiers for cosmetics.
PRODUCTION PROCESS OF SLES
The present analysis approaches Sodium Lauryl Ether Sulfate (SLES) production from chlorosulfonic acid, lauryl ethoxylate, and sodium hydroxide.
The process under analysis comprises four major sections: (1) Sulfation; (2) Neutralization; (3) Scrubbing; and (4) Packing.
Sulfation. Initially, the lauryl ethoxylate is batch sulfated by cholorosulfonic acid. Both reagents are fed to a glass-lined stirred, jacketed reactor, with the acid being gradually added to the reaction. The sulfation is carried out at 25 - 30°C under vacuum, over about a period of 2.5 hours. The gaseous HCl by-product is led off the sulfation product, and directed to a scrubber downstream. The sulfation product is fed to the neutralization.
Neutralization. The sulfation product is fed to a neutralization vessel, where it is contacted with a 50 wt% caustic soda solution along with process water for adjusting its active component. The neutralization reaction is carried out at a temperature below 45 °C, generating a 70 wt% sodium lauryl ether sulfate further routed to packaging.
Scrubbing. The HCl evolved during the sulfation is fed to a scrubber, where it is absorbed in process water generating a 33 wt% hydrochloric acid solution by-product.
Packing. SLES is packed in drums and then sent to warehouses at the facility’s outside battery limits (OSBL) to be stored.

Very good information.
Correct chemical info.thanks
Excellent video dear
Thank you
Please make this video in Hindi and Practical demonstration if possible, It really great help for those who wants to make SLES. Thank you!
Good details. Kindly refer further literatures.
Is Lauryl ethoxylate is different from Lauryl Alcohol ethoxylate or same. and whats the origin source is it coconut or palmic which both composed of Lauric acid. Is the Lauryl ethoxylate is the compounded version .thank u if ever u will answeer me.
Audio is very low
