Cetyl Trimethyl Ammonium Bromide is often found in hair conditioning and skin care products. Cetyl Trimethyl Ammonium Bromide is a cation when dissolved in aqueous solutions and is an effective antiseptic against bacteria and fungi.
Cetyl Trimethyl Ammonium Bromide is partially soluble in water as well as in oil. This allows for the mixing of the two repelling phases which would not be possible without the presence of the surfactant. This quality is utilized in the preparation of DNA. Cetyl Trimethyl Ammonium Bromide is used to form a buffer solution that is able to extract DNA.
Cetyl Trimethyl Ammonium Bromide is also being used in the preparation of gold nanoparticles which can be made into a number of shapes such as: spheres, rods, and bipyramids. There is currently much research using gold nanoparticles within the medical field. Drug delivery and tumor detection are a couple of the applications of gold nanoparticles currently being investigated.
