Dimethylol dimethyl hydantoin Description
DMDM Hydantoin(DMDMH) is often used as a preservative and fungicide to inhibit the growth of fungi, yeast and bacteria; this component will decompose to produce formaldehyde, which may cause irritation to the skin and have certain allergic risk.
Dimethylol dimethyl hydantoin Application
DMDM Hydantoin is a formaldehyde-donor preservative, that prevents or retards microbial growth, thereby protecting cosmetics and personal care products from spoilage.
Stable antibacterial properties in aqueous phase and oil-water emulsion: broad-spectrum antibacterial activity, can inhibit Gram-negative, positive bacteria, and have certain inhibitory effects on yeast and mold.
It can be used in resilience and rinse-off products such as creams, lotions, shampoos, conditioners, gels and wipes. It is generally added in an amount of 0.1 to 0.6%, and it can be added at room temperature or at up to 80 °C. Used in combination with parabens, IPBC, Kaisong, etc., it has better synergistic antiseptic effect.
