DMDMH is a low cost preservative with high antimicrobial activity used in various cosmetics and personal protection products. It has remarkable effect in inhibiting gram-positive and gram-negative bacteria, yeast and mold. Due to its high efficiency at low concentration, DMDMH can be fully compatible with cationic, anionic and non-ionic surfactants, emulsifiers and proteins. A series of experiments have proved that DMDMH has been stable in a long time, wide PH and temperature range. Because it is extremely soluble in water, DMDMH can be used in aqueous solution to facilitate production. Because it is colorless and tasteless, it can be used in various formulations.
Application:
DMDMH is highly effective in inhibiting the growth of gram-positive bacteria, gram-negative bacteria and other bacteria, as well as yeast and mold.
It can be used in daily chemical and personal care products, such as bath gel, shampoo, hair conditioner, skin cream, hand cream, mouthwash, facial cleanser, etc.
