Diazolidinyl urea is an Allantoin derivative, a highly effective, broad-spectrum antibacterial preservative with excellent activity against Pseudomonas species. It is non-irritating to the eyes, skin, and mucous membranes at use levels. It is also known under the trade name Germall II.
Diazolidinyl urea acts as a formaldehyde releaser. It is highly water-soluble, retaining its activity in the presence of proteins, nonionic surfactants, and most other common ingredients used in personal care formulations and hand sanitizers. It may be added directly to aqueous systems without heating.
In a hot process, Diazolidinyl urea should be introduced during the cooling stage, below 60°C, and recommended below 40°C. Because it is hygroscopic, it should be stored in tightly sealed containers when not in use.
Diazolidinyl urea is a well-studied and widely used preservative. However, due to its formaldehyde-releasing mechanism, some researchers consider it a potential carcinogen and a genotoxic agent. There are many reports of sensitization, including contact dermatitis and other allergic reactions.
Propylparaben is a propyl ester of p-hydroxybenzoic acid, a widely used broad-spectrum preservative used in personal care products, pharmaceuticals, and some foods.
Benzyl alcohol is a colorless liquid with a mild pleasant aromatic odor; it is a natural constituent of various essential oils, including jasmine, hyacinth, and ylang-ylang.
Imidazolidinyl Urea is a cosmetic preservative that is very active against Gram-negative, including Pseudomonas aeruginosa and positive bacteria. It has no activity against fungi and is synergistic with parabens.
Ethylparaben is an ethyl ester of p-hydroxybenzoic acid, a commonly used personal care preservative that provides a broad performance spectrum to secure the quality and safety of your final products.
Heptylparaben is a white crystalline powder or colorless crystal and is a longer alkyl ester of p-hydroxybenzoic acid. It is practically insoluble in water and soluble in alcohol, Phenoxyethanol, and propylene glycol.
As a C22 quat, Behentrimonium chloride belongs to the Behenyl class of surfactants. Lower irritation, more conditioning, better thickening, enhanced skin feel, and improved stick structure are all characteristics of this group of ingredients.
