Dimethyloldimethyl hydantoin /DMDMH Applications
Broad spectrum antibacterial, highly active, has good inhibitory and killing effects on Gram positive and Gram negative bacteria, and has a certain inhibitory effect on yeast and mold. Widely used in liquid cosmetics such as shampoo, conditioner, cream, shower gel, etc., it is safe and effective for wash off and retention products.
Suggested usage method:
- Due to its unique water solubility, it can be added to cream and wash off personal care formulas at a concentration of 0.2-0.6%.
- DMDMH can be added at room temperature or at a temperature of up to 80 ℃ to maintain high temperature for 6 hours before internal failure. It is best to add it during the cooling stage.
- If DMDMH is added to surfactants, its temperature is usually between 50 ℃ and 60 ℃, and the pH range is 7.5~8.5.
- Due to significant variations in the composition and formula of personal care products, it may affect the effectiveness of preservatives. We strongly recommend that you confirm the efficacy and stability of DMDMH before production.
