Viv-GMU

Glyceryl Undecylenate. Viv-GMU by Vivimed acts as a skin lightening active. Viv-GMU is an ester which combines the moisturisation from glycerine along with the antimicrobial properties of undecylenic acid. Whilst offering an excellent feel, Viv-GMU also offers protection against gram-positive and gram-negative bacteria, fungi, yeast and mold. Unlike some other common organic salts (eg: benzoates and sorbates), this ester shows no decrease in activity as the pH is varied from acidic to basic conditions. Viv-GMU is used in skin care products.
