Abstract
A non-linear surfactant, and particularly a non-linear surfactant comprising bi-functionalized molecules or particles having both hydrophobic and hydrophilic groups. The non-linear surfactant includes a nanoparticle template of a rigid molecular structure, wherein the nanoparticle comprises a molecule or a particle that is bi-functionalized with both hydrophilic and hydrophobic groups to obtain an amphiphilic nanoparticle. The template nanoparticle can be used as a surfactant, wetting agent, emulsifier, detergent or other surface active agents or for the preparation of nanoemulsions or dispersions. The non-linear surfactant can provide smaller particle sizes for emulsion suspensions and foams.
