DMDM hydantoin works by slowing and preventing spoilage in personal care products such as shampoos and hair conditioners, moisturizers and foundation makeup. As an antimicrobial, DMDM hydantoin can help prevent the growth of fungi, yeast and harmful bacteria.
DMDM hydantoin is a “formaldehyde donor,” which means that to work as a preservative and antimicrobial, it releases small levels of formaldehyde throughout the shelf-life of a personal care product or cosmetic products.
DMDM hydantoin has been approved for use in cosmetic and personal care products under established safety limits by the Cosmetic Ingredient Review and other scientific panels.
Uses & Benefits
Cosmetics and Personal Care Products
DMDM hydantoin is a preservative in cosmetics and personal care products. It works by slowing and preventing spoilage in products such as shampoos and hair conditioners, and in skin care products like moisturizers and makeup foundations.
DMDM hydantoin is also an antimicrobial agent used in cosmetics and personal care products. As an antimicrobial, it can help prevent the growth of fungi, yeast and harmful bacteria that can make people sick or give them rashes, for example.
Formaldehyde donors, also known as formaldehyde releasers, are ingredients used in small amounts in personal care products and cosmetics to help prevent mold and bacteria from growing and spoiling products. These compounds release small amount of formaldehyde over the shelf-life of a product.
DMDM hydantoin is safe as a cosmetic ingredient at current normal levels of use in products, according to scientific experts at the Cosmetics Directive of the European Union as well as an independent Cosmetic Ingredient Review panel.
To put formaldehyde exposures from DMDM hydantoin in personal care products into perspective, the tiny amount of formaldehyde released from a formaldehyde donor when shampooing your hair is about equivalent to the amount of formaldehyde naturally occurring in one medium-sized apple or pear.
Preservatives play important roles in many products people use every day – for example, by helping prevent the growth of harmful microorganisms and protecting products from spoilage or contamination.
