There are multiple types of aluminum stearates, generally classified as aluminum mono-, di-, and tri-stearate. They vary in terms of physical properties such as melting point, free fatty acids, and particularly the gelling properties.
Oils with a low viscosity are best thickened by aluminum di- and tri-stearate, whilst very viscous oils from stiffer gel when combined with aluminum mono- or di-stearates.
All aluminum stearates are highly hydrophobic, and feature outstanding transparency and excellent adhesion to metal surfaces. Due to their water repellency, aluminum di- and tri-stearate are used as hydrophobic agents in the building industry.
