Can cationic surfactant mix with other surfactants?

The effects of cationic surfactant mixing with other surfactants, polymers, proteins, and DNA are also shown and examined.

Do cationic surfactants adsorb polar and nonpolar surfaces?

Properties of single- and double-chain cationic surfactants and other special cationics are presented and discussed. The effects of cationic surfactant mixing with other surfactants, polymers, proteins, and DNA are examined. The distinct adsorption of cationic surfactants for nonpolar and polar surfaces is summarized.

How much is a cationic surfactant worth?

The total value of cationic surfactants produced today (2023) is around 2 billion US dollars, which is less than 5 % of the total market value of surfactants. Anionic and nonionic surfactants together account for almost 95 %. The fourth class of surfactants, zwitterionics, represents only around 1 % of the total surfactant market.

What is the difference between cationic and anionic surfactants?

Due to the combined action of electrostatic and hydrophobic association, the cationic surfactant gives a dramatic increase in viscosity, whereas the effect is moderate with the anionic surfactant. For the oppositely charged case, an additional typical effect is phase separation.

What are cationic surfactants used for?

The review discusses the most important established uses of cationic surfactants, as well as a number of emerging applications. Included in the latter category is a discussion about the importance of cationic surfactants for the successful development of mRNA vaccines. A classical application of cationic surfactants is disinfection.

Does cationic surfactant adsorb well on a solid surface?

Most surfaces carry a negative net charge, and the cationic surfactant will not only adsorb well on such surfaces, it will also stimulate adsorption of the nonionic surfactant through self-assembly into a mixed surfactant double layer. The surfactant double layer formed on the solid surface may be unsymmetrical.
