SurfThix™ DOE is a non-ionic liquid thickener for surfactant systems that are difficult to thicken, for example, those made with non-ionics like decyl or lauryl glucoside or those that won’t thicken well with salt, such as disodium sulfosuccinate. It can be used as an emollient, irritation reducer, and irritation mitigator in cleansing products such as shampoo, facial cleansers, and shower gels.

SurfThix™ DOE does not thicken sulfate-based surfactants.  Generally those are thickened well with salt.

  • The pH of the formulation should be adjusted to between 6.0 - 6.8 prior to the addition ofSurfThix™ DOE
  • at the end of the formulation process.

Usage Rate: 0.5% to 3% once the product has reached its final temperature
