pintaaktiivisiin
Pintaaktiivisiin is the Finnish term used for surface-active agents, a class of compounds that reduce surface and interfacial tensions between immiscible phases such as oil and water. They are typically amphiphilic, featuring a hydrophobic tail and a hydrophilic head, which drives adsorption at interfaces and enables self-assembly into structures like micelles above the critical micelle concentration.
Surfactants are categorized by the charge of their head group: anionic, cationic, nonionic, and zwitterionic. Common
Applications rely on altering interfacial properties to improve spreading, wetting, mixing, or dispersion. In detergency, surfactants
Environmental and safety considerations vary among compounds. Some surfactants are readily biodegradable and have low aquatic
