Chemical Name: DMDM Hydantoin

CAS No.: 6440-58-0

Molecular Fomula: C7H12N2O4

Molecular weight: 188.2

Appearance: colorless to light yellow transparent liquid

Assay:55%


Applications

The active ingredient of DMDMH, 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 80oC.


Packing

Standard packaging includes the following: 1.0kg/bottle; 10bottles/box, 25kg net weight plastic pail, 220kg net weight plastic drum. Other package sizes are available upon request.


Storage

Avoid freezing. Store at or near room temperature, out of direct sunlight. Keep containers tightly closed when not in use. Storage at temperatures below 10oCfor a long period of time, may cause formation of crystals, requires thawing and mixing prior to use, with no detrimental effect to product quality or efficacy.


Period of validity

24 months.


Keep stable antibacterial property in aqueous phase and oil-water emulsion: broad-spectrum antibacterial activity can inhibit gram-negative and gram-positive bacteria, and have certain inhibitory effect on yeast and mold.

Compatibility: It can be compatible with various components in cosmetics. The test results show that its bacteriostatic ability is not affected by surfactants, proteins and emulsifiers in cosmetics.

Application: It can be used for resident and washout products such as creams, lotions, shampoos, conditioners, gels and wet wipes. Generally, the additive amount is 0.1 ~ 0.6%, which can be added at room temperature or up to 80℃.Combined with nipogin ester, IPBC, Kaisong, etc., it has better synergistic anticorrosion effect.

How does science explain DMDM as an ingredient in cosmetics?

Summary: 

1) DMDM Hydantoin is commonly used as a preservative and fungicide, which can inhibit the growth of fungi, yeast and bacteria;

2) This ingredient will break down and produce formaldehyde, which may irritate the skin and pose a certain allergy risk. 

Ureide within health effects: DMDM b is a mild concern, because: this component was suspected to be causing the immune toxicity, the source is comprehensive China, Canada, the United States federal agency, the United States, California, Japan and the European Union legislation and research literature this composition was suspected to be causing skin or sensory system toxicity, origin is China, Canada, the United States federal agency, the United States, California, Japan and the European Union legislation and research literature function: preservatives, acid, acid formula is more suitable for use, used in shampoo, conditioner, cosmetics; DMDM was Dimethylol Dimethyl. DMDM Hydantoin used formaldehyde to create an environment unsuitable for microorganisms, thus achieving anti-corrosion effect and posing a certain risk of skin allergy.

More information: Ethylene urea, also known as Hydantoin, imidazoline-2, 4-dione, is a five-element nitrogen-saturated heterocyclic compound. It can be viewed as the product of two condensations of a molecule of glycolic acid and a molecule of urea. It is a derivative of imidazole, belonging to the dilactam and imide classes.It's the core structure of some drugs. Derivatives of ethanolidin, dantrillin as a muscle relaxant, furantoin as an antibiotic, and the anticonvulsants ethylphenytoin, phenytoin, mephenytoin and phosphophenytoin. The hydrogen atoms are replaced by chlorine and bromine atoms of nitrogen on the ureide b, such as dichloro dimethyl b within ureide (DCDMH), chlorine, bromine dimethyl ethyl ureide (BCDMH) and two bromine two methyl ethyl ureide (DBDMH), and water can release the hypochlorite and bromate, is a new type high efficient antiseptic fungicide, used for water disinfection, of killing bacteria, fungi, algae, has the broad spectrum effect...
