ALUMINUM ISOSTEARATES/MYRISTATES.

Valuable / ANTICAKING, EMULSION STABILISING, OPACIFYING, VISCOSITY CONTROLLING

This ingredient functions primarily as a non-aqueous viscosity-increasing agent and emulsion stabilizer. It enhances product texture, controls spreadability, and prevents phase separation in oil-based formulations.

Summary

viscosity controlling emulsion stabilising anticaking opacifying

Science

Mechanism of Action

It creates a structured network within the oil phase of a formulation, managing texture and controlling 'slip' on the skin. This metallic soap also prevents phase separation and contributes to product consistency, acting as an anticaking and opacifying agent.
