Carbomer Ultrez 21 Oil Tolerance

Based on the product description for Carbomer Ultrez 21, the maximum percentage of oil it can support is not explicitly stated.

Carbomer Ultrez 21 is primarily designed as a water-based gelling agent to thicken the aqueous phase of a formulation. While it can assist in stabilizing emulsions (mixtures of oil and water), its main function is not to thicken large amounts of oil directly. High concentrations of oil can interfere with the gelling mechanism of carbomers, which relies on the presence of water for hydration and neutralization.

Therefore, a specific maximum oil percentage cannot be provided from the product details. It is best suited for formulations where the water phase is dominant or for stabilizing emulsions with a dispersed oil phase.
