Abstract

A new method of dispersing the aggregated strontium hexaferrite (SrFe ₁₂O₁₉) magnetic nanoparticles in organic solvents such as propylene glycol monomethyl ether acetate (PGMEA), propylene glycol (PG), and glycerol, by an ultrasonic bath is reported herein. The particles size of SrFe₁₂O₁₉ after treatment with the PGMEA is in the range 70-100 nm. The structure of dispersed SrFe₁₂O₁₉ was characterized using transmission electron microscopy (TEM), high resolution scanning electron microscopy (HR SEM) and thermo gravimetric analysis (TGA). This dispersed material was used for the preparation of a topical magnetic cosmetic product as follows: The dispersion of SrFe₁₂O₁₉ in PG was mixed with "Dermud-Ahava Body Cream", an 'oil in water' emulsion of a Dead Sea mineral cosmetic, "AHAVA", and the magnetic properties of the created composite were determined. The ferrimagnetic behavior of the composite has been demonstrated as being very similar to the behavior of strontium hexaferrite itself.
