As a high-efficiency and broad-spectrum formaldehyde-releasing preservative, Diazolidinyl Urea (Jimei G-2) is white free-flowing powder, odorless or slightly characteristic-smelling. It is readily soluble in water, partially soluble in organic solvents including propylene glycol and ethanol, but insoluble in absolute ethanol and oily substances. This product exerts its antibacterial function by slowly releasing formaldehyde, which has a significant inhibitory effect on molds, yeasts and a variety of bacteria, especially Gram-positive bacteria. It has superior compatibility with various surfactants, cosmetic oils and polymers, and is widely used in various cosmetics and personal care products. It can effectively extend the product's shelf life, prevent microbial contamination, and is mild to the skin without obvious irritation at the using concentration.
Key Advantages
Convenient application:It is white powder, easy to disperse and dissolve, and does not affect the appearance, odor and use texture of the product after addition.
Broad-spectrum antibacterial property
It has a significant inhibitory effect on common microorganisms such as molds, yeasts and some Gram-positive bacteria, with a wide antibacterial range, effectively preventing microbial pollution of products.
Superior compatibility
It is well compatible with common cosmetic raw materials (such as silicone oil, squalane, triglycerides, surfactants, protein raw materials, etc.), will not be passivated by other raw materials, and can generate a synergistic effect when used with parabens to improve the antiseptic effect.
Mild and low-irritation
When used at the recommended concentration, it is gentle to the skin, without obvious toxicity, irritation and allergic risks, and can be used in mild care products such as children's cosmetics and eye cosmetics.
Flexible application
With good water solubility, it is suitable for various cosmetic formulations, and can exert excellent antibacterial effect in a wide pH range (4.0-8.0), with better effect in acidic to neutral environments.
