Application:
The active ingredient of DMDMH, DMDM Hydantoin, is permitted for use in cosmetic and personal care products in the USA and the EU to a maximum concentration of 0.6%.DMDMH is compatible with essentially all cosmetic ingredients, such as surfactants, emulsifiers, proteins, aloe and amines. DMDMH is an excellent preservative for both leave-on and rinse-off products such as shampoos, creams, lotions, bubble baths, rinses, wipes and towelettes. It is easy to handle, very stable and cost-effective. The recommended use level is 0.1～0.6% by weight of product as supplied. DMDMH exhibits an excellent synergistic preservative effect in combination with Iodopropynyl Butylcarbamate (IPBC), Parabens and Isothiazolinones. It is stable over a wide range of pH and temperature conditions. It does not discolor product when combined with additives or by changes in pH. It can be added at a wide range of temperatures from ambient to elevated 80℃.
