Application：

2-Bromo-2-nitropropane-1,3-diol, known as Bronopol, is a broad spectrum bactericide effective against both gram-positive and gram-negative bacteria. It is a white to slightly yellow crystals; melting point 130 - 133 C;  soluble in water and polar organic solvents. It reacts with some metals, amines and alkaline compounds. But it is stable in acidic media. Its bacteriostatic and bacteriacidal properties are useful in cosmetics as a preservative. It is also used in coating materials, slurries, paper mills and water circulation systems for the effective preservation against bacteria and fungi.

The most widely used biocides ( antiseptic agents, preservatives, bactericides, slimicides, fungicides) in cosmetics are parabens, isothiazolones, formaldehyde and formaldehyde releasing substances.

Formaldehyde is the simplest aldehyde with the formula HCH=O. It is a gas at room temperature with a pungent smell. It cannot be readily isolated or handled in the pure state because it is extremely reactive. Formaldehyde reversibly polymerizes to its cyclic trimer 1,3,5-trioxane or the linear polymer polyoxymethylene. It is readily oxidized to form formic acid in the air. It is commercially available as an aqueous solution usually 37-50% w/w. Formalin is the solution of formaldehyde in water. Paraformaldehyde is a white crystalline solid formed by polymerization of formaldehyde. Formaldehyde kills most bacteria, and used as a disinfectant and as a preservative and fixative for pathologic specimens. Formaldehyde cross links amino groups. In industry formaldehyde is used in the production of thermoset resins, functional polyols, explosive, hexamine and other chemicals. Examples of formaldehyde-releasing biocides are:

• Imidazolidinyl Urea (CAS RN: 39236-46-9)
• Diazolidinyl Urea (CAS RN: 78491-02-8)
• 1,3-Dimethylol-5,5-dimethylhydantoin (CAS RN: 6440-58-0)
• Bronopol (CAS RN: 52-51-7)
• Tris(hydroxymethyl)nitromethane (CAS RN: 126-11-4)
• Polyethylene glycol sorbitan monolaurate (CAS RN: 9005-64-5)

Poly(acrylamide, trimethylaminoethyl methacrylate chloride) (CAS RN: 35429-19-7)
