“…The ability of surfactants to organize themselves in complex supramolecular structures, such as micelles, liposomes, lyotropic liquid crystalline phases, or microemulsions, is mainly a consequence of their amphiphilicity. This amphiphilicity can be modulated via the modification of the surfactant molecular structure, i.e., the balance between hydrophilic and hydrophobic parts (Blunk et al, ). This modulation has also an influence on the flexibility of the surfactant, i.e., its ability to depart from the “optimal curvature” that minimizes the free energy of the interface (Chevalier, ).…”

“…The aggregation of a surfactant around the protein forms a complex, which increases the stabilization of the protein. Depending on its size and its uniformity, the protein/surfactant complex can crystallize in an ordered lattice suitable for high‐resolution structural determination (Blunk et al, ).…”

Surfactants find applications in almost every chemical industry, such as household and industrial cleaning, paper, inks, agrochemicals, and personal care or pharmaceuticals. However, their production and use can have a negative impact on the environment and health. Increasing environmental concerns and the strong interest in renewable resources have led to the development of innovative and environmentally friendly surfactants produced by clean and/or sustainable technologies. The aim of this review is to explore the different types of surfactants and their architectures. Then, it will describe the two categories of renewable surfactants: biosurfactants obtained by fermentation, and bio‐based surfactants containing either a bio‐sourced polar head group or a bio‐sourced hydrophobic tail. Finally, this review will focus on highly specialized applications of surfactants (protein crystallization, transfection, and nanotechnology), which are closely related to the ability of surfactants to organize themselves in supramolecular architectures.

“…However, water and soil can become contaminated when a large amount of surfactant is discharged into the environment. In recent years, to meet requirement of the environmental protection and biological safety, increasing attention has been paid to develop and promote environmentally friendly surfactants (Blunk et al, ; Infante et al, ; Ohta et al, ; Ren et al, ; Tabohashi et al, ; Yoshimura et al, ). Nowadays, “greener” surfactants are demanded for both industrial and domestic use (Kobayashi et al, ).…”

Amino acid‐based surfactants are environmentally friendly surfactants, which have aroused increasing interest. In the application of amino acid‐based surfactants, they are often compounded with other kinds of surfactants to obtain formulations that meet certain requirements. Herein, sodium lauroyl glycinate (C12‐Gly‐Na) was selected as a representative amino acid‐based surfactant to compound with an anionic surfactant (sodium dodecyl sulfate [SDS]), a cationic surfactant (dodecyl trimethyl ammonium Bromide), and a nonionic surfactant (Triton X‐100: p‐octyl polyethylene glycol phenyl ether). Surface tension measurements and interfacial dilational rheological experiments were performed to study the interfacial behaviors of C12‐Gly‐Na and its mixtures. The results show that mixture systems have better interfacial activity than individual C12‐Gly‐Na and there is an obvious synergy between C12‐Gly‐Na and C12TAB under strong electrostatic attraction. Thus, the C12‐Gly‐Na/C12TAB mixture shows lower critical micelle concentration (CMC) and γCMC and higher dilational modulus than the individual surfactants. Besides, the film formed by the C12‐Gly‐Na/C12TAB mixture has higher viscoelasticity than single C12‐Gly‐Na and its mixtures with SDS and TX‐100. With the increase of bulk concentration, the dilational moduli of C12‐Gly‐Na, C12‐Gly‐Na/SDS, and C12‐Gly‐Na/TX‐100 run through two maxima, while, due to stronger electrostatic attraction, only one maximum appears in the C12‐Gly‐Na/C12TAB system. The study of the interfacial properties of amino acid surfactant and its mixtures with other surfactants provides a theoretical foundation for potential applications in cosmetic, food processing, and daily chemical industries.
