Launch of a natural and high-performance oil rheology modifier: EstoGel® Max -RPSO certification

ExpertGel is an innovative, water-soluble rheology modifier.
Liquid at room temperature, the solution turns into a gel at higher temperatures. This unique rheological behavior allows to obtain very specific properties such as emulsion stabilization, SPF reinforcement or control of active ingredients release.


EstoGel® M is an innovative rheology modifier based on castor oil derivatives. EstoGel® M is 91% biobased according to ISO 16128 standard and gels polar to medium polar oils. Based on supramolecular chemistry, the gel is shear thinning. It allows the formulation of clear gel with a very good suspension capacity at low concentration. EstoGel® M also gels perfumes, which opens many creative applications in this field.

EstoGel® Green

EstoGel® Green the new oil gelling agent 100% natural origin and COSMOS approved. EstoGel® Green is a rheology modifier with suspensive and rheofludifying properties that allows to create non brittle, transparent and sprayable gels with a very pleasant sensory touch. The versatility of EstoGel® Green allows the development of various galenics (anhydrous formulas, emulsions, sticks…) for a multitude of applications.

EstoGel® Max

EstoGel® Max is a natural and high performance oil gelling agent. It allows the formation of structuring anhydrous formulations while maintaining a certain flexibility to optimize their application on the skin. It makes possible to formulate anhydrous formulations over a wide viscosity range, from liquid to solid, with excellent suspensive capacities. Its easy implementation at 85°C and the transparency of the products obtained make this ingredient, among other things, an ideal ally for the formulation of transparent sticks.
