BENEFITS OF DMDM HYDANTOIN (DMDMH):
Effective broad-spectrum preservation against gram-positive and gram-negative bacteria, yeast, and mold.
For its high water solubility, DMDM Hydantoin (DMDMH) is particularly suggested for aqueous formulations and emulsions.
DMDM Hydantoin (DMDMH) extends shelf life of personal care products typically to 6-18 months.

Compatible with most cosmetic ingredients.
DMDM Hydantoin (DMDMH) is non-irritating and non-sensitizing.

WHAT DOES DMDM HYDANTOIN (DMDMH) DO?
The main benefits of DMDM Hydantoin (DMDMH) lie in its antimicrobial properties.
In basic terms, this means DMDM Hydantoin (DMDMH) can help prevent the growth of mold and other fungi, yeast, and harmful bacteria, Factor says.
As a result, products that contain DMDM Hydantoin (DMDMH) might remain fresher (and safer to use) for longer periods of time.

Preservatives like DMDM Hydantoin (DMDMH) play an especially important role in products you keep in your shower — think shampoo, conditioner, and body wash — since the warm, humid conditions can encourage bacteria to grow.

BENEFITS OF DMDM HYDANTOIN (DMDMH):
DMDM Hydantoin (DMDMH) helps your personal-care items stay fresh for long periods.
DMDM Hydantoin (DMDMH) stops or slows down the growth of potentially harmful fungi, yeast, and bacteria.

CORE ADVANTAGES AND APPLICATIONS:
Highly Effective Antimicrobial Preservative

*Mechanism of Action:
DMDM Hydantoin (DMDMH) slowly releases formaldehyde to destroy the protein structure of microorganisms, inhibiting the growth of bacteria, mold, and yeast, thereby extending product shelf life.

*Applications:
DMDM Hydantoin (DMDMH) is widely used in rinse-off and leave-on products such as shampoo, conditioner, body wash, and skincare to prevent spoilage caused by microbial contamination.

*High Efficiency at Low Concentrations
Compared to other preservatives (such as parabens), DMDM Hydantoin (DMDMH) achieves antibacterial effects at lower concentrations (typically 0.05%-0.2%), minimizing its impact on product formulations.

*Stability and Compatibility
Stable to light, heat, and pH fluctuations, DMDM Hydantoin (DMDMH) is compatible with most cosmetic ingredients without affecting product texture, scent, or color.

*Water-Solubility Advantages
High water solubility allows for easy, even dispersion in formulations, making DMDM Hydantoin (DMDMH) particularly suitable for preservatives in water-based products (such as toners and lotions).

DMDM HYDANTOIN (DMDMH) IS FIND IN:
You can find DMDM Hydantoin (DMDMH) in:
*Makeups
*Makeup removers
*Shampoos
*Conditioners
*Hair styling products
*Moisturizers
*Liquid hand soaps
*Facial cleansers
*Exfoliants or scrubs

Formaldehyde-releasing preservatives like DMDM Hydantoin (DMDMH) help keep beauty products from spoiling.
While formaldehyde-releasing ingredients can be dangerous in high levels, these chemicals are found naturally in safe, small amounts in many foods.
They include:
*Bananas
*Apples
*Plums
*Grapes
*Onions
*Carrots
*Spinach
*Seafood
*Beef
*Poultry

Our bodies, and those of most other living organisms, also make small amounts of formaldehyde as part of the normal process of metabolism.

CHEMICAL AND PHYSICAL PROPERTIES OF DMDM HYDANTOIN (DMDMH):
CHEMICAL STRUCTURE OF DMDM HYDANTOIN (DMDMH):
DMDM Hydantoin (DMDMH) belongs to the hydantoin family of compounds, chemically known as 1,3-dihydroxymethyl-5,5-dimethylimidazolidine-2,4-dione.
Its molecular structure consists of two hydroxymethyl groups (-CH₂OH) and a hydantoin ring, which enables DMDM Hydantoin (DMDMH) to slowly release formaldehyde (HCHO), thereby exerting its antimicrobial activity.

PHYSICAL PROPERTIES OF DMDM HYDANTOIN (DMDMH):
*Appearance:
DMDM Hydantoin (DMDMH) is a white to off-white solid powder.

*Solubility:
DMDM Hydantoin (DMDMH) is freely soluble in water (140 g/L at 20°C) and soluble in organic solvents such as methanol and dimethyl sulfoxide (DMSO).

*Stability:
DMDM Hydantoin (DMDMH) is stable in a dry environment, but may decompose in DMSO solution; has a wide pH range and can remain active under acidic to neutral conditions.
