Product Description

SupGuard GM-A provides a broad spectrum of antibacterial activity against Gram-positive and Gram-negative bacteria, including Pseudomonas species; and some protection against yeast and mold. The active ingredient of SupGuard GM-A, Diazolidinyl Urea, is permanently listed by the EU at levels up to 0.5% without restrictions. SupGuard GM-A is safe for both leave-on and rinse-off products and provides effective protection at low concentration levels. It is typically used at concentrations from 0.1～0.3%. SupGuard GM-A is compatible with virtually all cosmetic ingredients. It is not inactivated by emulsifiers, proteins or other ingredients that affect other preservative materials. SupGuard GM-A is an excellent preservative for shampoos and hair conditioners. It is synergistic with other preservative materials, especially parabens and/or Iodopropynyl Butylcarbamate (IPBC). This combination is a complete cosmetic preservative systems that is effective at protecting well formulated products from bacterial, yeast and mold contamination during use. The activity against yeast and mold does not decrease while SupGuard GM-A is used in combination with parabens even when paraben effectiveness has been diminished by interaction with nonionics or proteins, or migration into the oil phase.
