DMDM Hydantoin (DMDMH)   Basic Information INCI Adopted Name: DMDM Hydantoin CAS Registry No.: 6440-58-0 EINECS No. 229-222-8 Molecular Formula: C7H12N2O4 Molecular Weight: 188.18 Structural Formula:   Synonyms: DMDMH; 1,3-Dihydroxymethyl-5,5-Dimethylhydantoin 2. Quality Specification Item Specification Appearance Colorless to light yellow clear liquid Odor Odorless or characteristically mild Nitrogen 7.8~8.6% Specific Gravity( 25ºC) 1.14~1.17 pH 5.0~7.0 Total Solids 54~56% As 0.001% max Pb 0.004% max. 3. Packing DMDM Hydantoin Standard packaging includes the following: 25kg net weight plastic pail 200kg net weight plastic drum Other package sizes are available upon request. 4. Storage DMDM Hydantoin Avoid freezing. Store at or near room temperature, out of direct sunlight. Keep containers tightly closed when not in use. Storage at temperatures below 10°C for 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. 5. Period of validity 24 months 6. Properties Solubility: Very soluble in water; soluble in lower alcohols and glycols. Antimicrobial Activity: DMDM Hydantoin is very effective against Gram-positive and Gram-negative bacteria, also provides some protection against yeasts and molds. Toxicological Data Acute oral toxicity LD50 (mice): >2000mg/kg Eye irritation (rabbits): Non-irritating at 0.6% aqueous solution Primary skin irritation (rabbits): Non-irritating at 0.6% aqueous solution 7. Applications The active ingredient, 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%. DMDM Hydantoin is compatible with essentially all cosmetic ingredients, such as surfactants, emulsifiers, proteins, aloe and amines. DMDM Hydantoin 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. DMDM Hydantoin 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.
