Glydant Plus is a water soluble synergistic preservation system that combines two well-known and traditional chemistries for personal care applications. It is a solid and is granular in form. The combination of DMDM Hydantoin and Iodopropynyl Butylcarbamate (IPBC) allow for a dual mode of action, offering broad spectrum efficacy. Glydant Plus is also highly effective in inhibiting the growth of gram positive and gram negative bacteria, yeasts and mods without the need of additional auxiliary preservatives.
