Having Difficulties Thickening Glutamate Surfactants?

gel - thickening glutamate surfactants

Up to date, thickening glutamate surfactants is the main problem with their application. This puts off formulators from using these surfactants as they cannot achieve the viscosity that they desire.

However, glutamate surfactants remain a popular choice to create green products. They are sulfate-free alternatives and are mild, biodegradable and eco-friendly. Furthermore, they offer superior ease of rinsing and water-saving properties.

Why are glutamate surfactants difficult to thicken?

Glutamate Surfactants

  • These surfactants are unique in their structure. It has a big hydrophilic head with two carboxylate radical and relatively small hydrophobic tail.
  • Their big hydrophilic heads prevent the increase of packing parameter.
  • Easy to form spherical micelle, not rod like micelles, worm-like micelles etc.

 

Spherical micelles do not give increased viscosity, however, when the micelles have an elongated configuration, for instance are rod-shaped or worm-shaped, they become entangled with one another thereby increasing the viscosity of the fluid (Crews and Huang, 2010).
