DMDM Hydantoin: An Effective Cosmetic Preservative
DMDM hydantoin is a clear, aqueous preservative containing 55% of the active ingredient dimethyloldimethylhydantoin. It is a low-cost, highly effective preservative that offers protection against a broad spectrum of microorganisms, including Gram-positive and Gram-negative bacteria, yeasts, and molds. It is recommended for use in rinse-off and leave-on personal care applications including facial cleansers, hand cleansers, body cleansers, hair shampoos, hair conditioners, moist towelettes, sun care, and skin care.
Because DMDM hydantoin is a formaldehyde donor, it releases small amounts of formaldehyde over time which works to keep mold and bacteria from forming. At a concentration of less than 1 percent in cosmetics and personal care products, the amount of formaldehyde released from shampooing one’s hair is less than the amount of formaldehyde that is naturally produced by one medium sized apple or pear. DMDM hydantoin is poorly absorbed by the skin and is not a skin irritant except in cases of people with severe formaldehyde allergies. There are no adverse effects from oral exposure.
As one of the best antimicrobial agents on the market, DMDM hydantoin helps to prevent the growth of harmful fungi and bacteria over the useful life of many personal care products. It is a very safe preservative at recommended concentrations and is one of the most frequently used formaldehyde releaser preservatives on the market today.
