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 s
hampoos, 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℃.Packaging
Standard packaging includes the following:
1.0kg/bottle; 10bottles/box
