Highly purified micro fine white bentonite
Stabilize cosmetic and personal care formulations the natural way
EXPANDA® GOLD is a natural, highly purified micro fine white bentonite. It has functional use as binder, stabilizer, suspension agent, a thickening agent, and rheological modifier. Its excellent suspension properties are due to the shear-thinning, thixotropic behavior of EXPANDA GOLD dispersions, which increases the yield value or resting viscosity of the final formulation. EXPANDA GOLD combined with gums and organic thickeners, such as xanthan, carboxymethylcellulose, or carbomers synergistically increases viscosity and the yield value. It provides additional water absorbent capacity with superior stability in the presence of organic compounds. It has application as a thickening, suspension, and stability agent in pharmaceutical, cosmetics, personal care, and household products. EXPANDA GOLD is sterilized by gamma irradiation.
