VEEGUM® HV Magnesium Aluminum Silicate provides excellent emulsion and suspension stability at low use levels. This grade is used in a variety of personal care and pharmaceutical products.
VEEGUM HV is a highly purified smectite clay suspension stabilizer, emulsion optimizer and rheology modifier. VEEGUM HV also reduces the slippery or sticky feel of gums and polymers, while providing a silky, tack-free feel in topical preparations. This smectite clay is synergistic with common thickeners such as VANZAN® xanthan gum and CMC. These combinations will provide greater thickening, stabilizing and suspending properties than those developed by the individual components of the mixture.
Typical Use Levels: Between 0.5% and 3%
