For formulators in the personal care industry, selecting the right preservative is critical for product efficacy and consumer safety. NINGBO INNO PHARMCHEM CO.,LTD. offers DMDM Hydantoin (CAS 6440-58-0), a widely recognized and effective preservative. This guide aims to provide formulators with a thorough understanding of its properties and applications.

DMDM Hydantoin is a broad-spectrum preservative known for its ability to combat a wide range of microorganisms, including bacteria, yeast, and mold. Its chemical structure allows it to function as a formaldehyde releaser, a mechanism that contributes to its potent antimicrobial activity. This makes it an invaluable ingredient for preserving water-containing formulations, which are common in personal care products like shampoos, conditioners, lotions, and makeup. The primary benefit of using DMDM Hydantoin is its capacity to extend the shelf life of these products by preventing spoilage and contamination.

In terms of chemical properties, DMDM Hydantoin is typically supplied as a clear liquid and is highly soluble in water. This characteristic makes it easy to incorporate into aqueous-based formulations during the manufacturing process. It performs optimally within a specific pH range, generally between 4 and 10, offering flexibility in formulation design. The recommended usage levels for DMDM Hydantoin vary, with typical applications ranging from 0.1% to 0.6% of the total formulation, though regulatory limits may permit up to 1% in certain regions.

Safety and regulatory compliance are paramount in the personal care industry. DMDM Hydantoin is subject to regulations in major markets, including the US and EU, which set limits on the concentration of formaldehyde releasers permitted in cosmetic products. These regulations are in place to ensure that the amount of formaldehyde released is minimal and poses no significant risk to the vast majority of consumers. While it is a known allergen for a small percentage of the population, particularly those sensitive to formaldehyde, its use within approved limits is considered safe by major regulatory bodies and scientific assessment panels.

When formulating with DMDM Hydantoin, formulators should consider its synergistic effects with other preservatives, if used, and ensure compatibility with other ingredients in the formulation. Its water solubility makes it particularly suitable for products such as liquid soaps, shampoos, conditioners, and creams. NINGBO INNO PHARMCHEM CO.,LTD. provides DMDM Hydantoin that meets stringent quality standards, ensuring reliable performance for your formulations.

In conclusion, DMDM Hydantoin remains a key preservative in the personal care industry due to its broad-spectrum efficacy and ease of formulation. By adhering to recommended usage levels and regulatory guidelines, formulators can effectively utilize DMDM Hydantoin to ensure the stability, safety, and longevity of their products.
