Biosurfactants Current Trends and Applications

At the interface of the two immiscible liquids the biosurfactants intervene replacing the hydrophobic or the hydrophilic molecules with their corresponding moieties thus bringing down the inter-molecular forces between the solvent molecules and thus reduce the interfacial and surface tension forces (Jahan et al. 2020). Tayeb et al. (2019) suggest that by altering the structural composition of protein biosurfactants their interfacial properties can be improved which may enhance their applicability in industry. The zwitter ionic surfactant cocamidopropyl betaine (CAPB) in conjunction with rhamnolipid and sophorolipid biosurfactants can help in the reduction of surface tension (Zhou et al. 2019). Removal of hydrophobic organic compounds from land and aquatic bodies is a matter of environmental concern and as a remedy saponins aids in removal of hydrophobic organic compounds by forming saponin micelles (Mulligan 2009).

Hair shampoos form one of the main groups of body wash cosmetics. From the physicochemical point of view, shampoos are usually aqueous solutions of surface active agents and various additives including conditioning agents, medicinal compounds (e.g. anti-dandruff additives), pH regulators, preservatives, fragrances, colorants, substances giving formulations a pearly appearance, etc.[1–7] The key determinants of the quality of modern hair shampoos are surfactants forming the shampoo base. They are most commonly anionic surface active agents which, however, can cause epidermal dryness and irritation.[8–10] Current research is increasingly focused on the application of raw materials which, while maintaining good washing properties, would also meet other requirements applicable to shampoos including a mild effect on the skin. Up to the present day one of the compound groups with potential applications as components of hair and body wash cosmetics comprises amphoteric surfactants. One of them is the widely used surfactant Cocamidopropyl Betaine (CAPB).
