General description
Preservative for the cosmetic industry
1,3-Dimethylol-5,5-Dimethyl Hydantoin
DMDMH is a preservative that is highly soluble in water and adaptable enough for a wide range of personal care and detergent based products.
Applications
Dimetilol dimetil hidantoyin can be particularly effective in detergent- based formulations which can have some inherent antimicrobial activity, but which are susceptible to growth of some types of micro-organisms. DMDM Hydantoin offers the following benefits:
– broad- spectrum activity against Gram- negative and Gram- positive bacteria, yeast and mould
– effective over the range pH 3.0 – 8.0
– Retains activity in the presence of nonionic surfactants and most other common ingredients of personal care products
– Highly soluble in water and readily incorporated into products
DMDMH may be used in many types of personal care products including shampoos, hair conditioners, creams, lotions, baby products, eyeliners, mascaras and almost all water- based cosmetics and toiletries.
Hydantoin is an ideal preservative for bulk surfactants.
The recommended use level of DMDMH to preserve most product types is normally in the range of 0.15-0.4 % based on the total weight of the finished product.
pH stability
Nipaguard® DMDMH remains fully stable over a wide pH range from 3.0-8.0.
Temperature stability
Dimetiloldimetilhidantoin should be incorporated during the cooling stage of hot processes. The recommended maximum handling temperature is 60°C.
