DMDM Hydantoin, also known as Dimethylol dimethyl Hydantoin, is primarily used in personal care products as a formaldehyde-releasing preservative. Originally developed as an odorless alternative to formaldehyde for use in permanent-pressed fabrics, DMDM Hydantoin has proven effective in preserving aqueous-based personal care products. It provides antimicrobial protection against bacteria, extending the shelf life and safety of products such as shampoos, hand soaps, face creams, sunscreens, lotions, bubble baths, and wipes. Typical use concentrations range from 0.20% to 0.60%, ensuring product integrity while maintaining consumer safety.
What is DMDM Hydantoin, and what is its primary use in personal care products?
DMDM Hydantoin, also known as Dimethylol dimethyl Hydantoin (DMDMH), is a derivative of formaldehyde and dimethyl hydantoin. It is primarily used as a preservative in personal care products. Its function is to release a small amount of formaldehyde over time, which helps to protect products from bacterial contamination.
In what types of products can DMDM Hydantoin typically be found?
DMDM Hydantoin can be found in a variety of aqueous-based personal care products. These include shampoos, hand soaps, face creams, sunscreens, lotions, bubble baths, and wipes. It is valued in these products for its antimicrobial properties.
What concentrations of DMDM Hydantoin are typically used in personal care formulations?
The typical use levels of DMDM Hydantoin in personal care products range from 0.20% to 0.60%. These concentrations are designed to be effective in preserving the product while maintaining safety for consumer use.
Why was DMDM Hydantoin chosen as a preservative over formaldehyde in some applications?
DMDM Hydantoin was originally designed as an odorless alternative to formaldehyde in permanent-pressed fabrics. It was later adopted in personal care applications due to its ability to effectively release small amounts of formaldehyde over time, offering antimicrobial protection without the strong odor associated with formaldehyde.
Can you elaborate on the function of DMDM Hydantoin as a formaldehyde-releasing preservative?
As a formaldehyde-releasing preservative, DMDM Hydantoin slowly releases formaldehyde in small, controlled amounts. This gradual release provides continuous protection against bacteria, helping to extend the shelf life and maintain the integrity of personal care products.
