Innovative rheological agent for skin cleansing solutions with low-to-medium surfactant!

Rheomer® AB 25T is the hydrophobically-modified alkali-swellable emulsion (HASE) polymer for personal care formulations designed to provide efficient thickening and good suspension properties for a mild and caring cleansing thanks to a low to medium surfactant chassis content. With Rheomer® AB 25T, formulators bring the sought textures and additional functionalities which drive consumer preferences and making the whole sensorial experience more pleasurable.


From high viscosity to clear solution...

Rheomer® AB 25T allows for a significant reduction of thickener inclusion level in cleansing formulations. Rheomer® AB 25T displays synergistic thickening and high clarity in the presence of salt.

...With desired suspensions

They yield point of a formulation in typically recognized as a measure of the ability of a composition to effectively suspend particles. Dispersed particles will remain suspended if the yield value is sufficient to overcome the effect of gravity or buoyancy on these particles. With Rheomer® AB 25T, yield stress > 1 Pa which is typically sufficient to suspend most particles is very easily obtained. With Rheomer® AB 25T, the lower the surfactant content, the higher the yield stress.
