Laureth-7 carboxylic acid is an AKYPO RLM product.
The Akypo products offer a wide range of secondary surfactants with excellent tolerance against hard water. 
Depending on the carbon chain length and the ethoxylation degree the products show characteristic application properties.
Akypo LF grades, with a chain length from C4 to C8, are low foaming surfactants with high dispersing and hydrotropic abilities. 

Akypo RLM products have a C12-C14 alkyl chain and their degree of ethoxylation ranges from 2.5 to 10 EO. 
They offer good foaming at different pHs. 
Similar to the Akypo soft grades they are mild co-surfactants and function as emulsifiers and solubilizers.
Finally the Akypo ro products bring excellent lime soap dispersing properties and add some anti-corrosion benefits. 
They can be used in conveyor belt lubricants.
