RHEOSOL OP is a cationic acrylic homopolymer of Polyquaternium 37 in powder form. It is free of the carrier oils and surfactants associated with traditional liquid forms of this thickener type. It offers the formulator an alternative thickener choice where such oils and surfactants are considered undesirable in a finished cosmetic formulation. Its prime function is as an additive to control the viscosity and rheology in finished products. Applications are within the toiletries and cosmetics industry.

Features & Benefits

Performance Highlights
  • RHEOSOL OP can be added to personal care formulations at any stage of manufacture. It is easily dispersed and does not require neutralization or heat, thickening simply by agitation.
  • RHEOSOL OP produces opaque formulations. (KLEASOL 200ST is recommended for formulations requiring absolute clarity)
  • RHEOSOL OP aids suspension and stabilization of other co-ingredients, and its high thickening efficiency means that only low usage levels are required in many applications.
