Kemsurf ESD
Product Category: Anionics
Sodium Laureth-3 Sulphate (Sodium Laureth-3 Sulfate)
Synonym: Sodium lauryl ether sulphate
Manufactured using a natural C12-14 alcohol + 3EO which is sulphated and then neutralised to form a sodium salt.
Properties
​
-
Excellent detergent - Does not show a loss of detergency in brine or hard water.
-
Solubility - The good solubility characteristics make them especially useful for use in alkaline liquid formulations.
-
Excellent foaming agent
-
Salt thickening - Show a pronounced thickening with the addition of sodium chloride to a dilute solution.​
-
Compatibility with aqueous ions - Stable to hard water and has excellent lime soap dispersing properties, due to the calcium salt being soluble.
-
Chemical and temperature stability - Prone to hydrolysis in aqueous solution at acid pH and high temperatures (not suitable for use above 50°C).​
Applications
-
Household products - ​Kemsurf ESD is used as a foam stabiliser and detergent in dish-washing liquids.
A major component of low temperature or low phosphate-content heavy-duty fabric laundry liquids and powders.
Carpet shampoos
Hard surface cleaners
-
Oilfield chemicals - ​Used as foaming agents in foam drilling where tolerance to salt and hard water is important.
-
Gypsum board production - ​Foaming agent with tolerance to high concentrations of calcium ions.
