“…Beyond agrochemical applications, the industrial use of several anionic surfactants, such as calcium dodecylbenzene sulfonate (Rhodacal 60/BE), sodium dodecylbenzene sulfonate (Neopelex G-65), ammonium lauryl sulfate (ALS), and sodium lauryl sulfate, in the formulations of laundry detergents and cleaning supplies is also significant ( 58 , 72 , 80 ). Sulfonates are among the most widely used anionic surfactants in personal care and household products ( 81 , 82 ).…”

Chemical substances applied in animal husbandry or veterinary medicine and in crop protection represent substantial environmental loads, and their residues occur in food and feed products. Product approval is governed differently in these two sectors in the European Union (EU), and the occurrence of veterinary drug (VD) and pesticide residues indicated by contamination notification cases in the Rapid Alert System for Food and Feed of the EU also show characteristic differences. While the initial high numbers of VD residues reported in 2002 were successfully suppressed to less than 100 cases annually by 2006 and on, the number of notification cases for pesticide residues showed a gradual increase from a low (approximately 50 cases annually) initial level until 2005 to more than 250 cases annually after 2009, with a halt occurring only in 2016. Main notifiers of VD residues include Germany, Belgium, the UK, and Italy (63, 59, 42, and 31 notifications announced, respectively), and main consigning countries of non-compliances are Vietnam, India, China, and Brazil (88, 50, 34, and 23 notifications, respectively). Thus, countries of South and Southeast Asia are considered a vulnerable point with regard to VD residues entering the EU market. Unintended side effects of VDs and plant protection products may be caused not only by the active ingredients but also by various additives in these preparations. Adjuvants (e.g., surfactants) and other co-formulants used in therapeutic agents and feed additives, as well as in pesticide formulations have long been considered as inactive ingredients in the aspects of the required main biological effect of the pharmaceutical or pesticide, and in turn, legal regulations of the approval and marketing of these additives specified significantly less stringent risk assessment requirements, than those specified for the active ingredients. However, numerous studies have shown additive, synergistic, or antagonistic side effects between the active ingredients and their additives in formulated products; moreover, toxicity has been evidenced for various additives. Therefore, toxicological evaluation of surfactants and other additives is essential for proper environmental risk assessment of formulations used in agriculture including animal husbandry and plant protection.

“…Although α‐MES was fundamentally studied in the 1950s (Weil et al, 1953; Weil and Stirton, 1956), it was only acknowledged as a class of surfactant in the 1980s (Hibbs, 2006). In the initial stages of development, α‐MES is associated with several limitations, mainly on its poor solubility, high tendency to hydrolyze, longer processing time, irritancy, dark color, and presence of skin sensitive components.…”

α-Sulfo fatty methyl ester sulfonate (α-MES) is one of the anionic surfactants that is currently used commercially in the cleaning industry. Although the fundamental studies on α-MES were initiated as far back as the 1950s, it was only recognized as a class of surfactant in the 1980s. In the initial stage of development, α-MES has been associated with many technical impediments, which created a fear factor for the detergent industry to consider this oleobased anionic surfactant for commercial production. However, all the technical adversities have been resolved after five decades of continuous active research and development activities. This paper will review the history, chemistry, process development, processing technologies, performance, commercial production, and applications of oleobased based α-MES with special emphasis on palm oilbased α-MES. The paper also will highlight the challenges and adversities faced by the technology developers and product formulators toward the commercialization of α-MES as an active ingredient in the production of powder and liquid laundry detergents.

Background Predatory flagellates and ciliates are two common bio-contaminants which frequently cause biomass losses in Chlorella mass culture. Efficient and targeted ways are required to control these contaminations in Chlorella mass cultivation aiming for biofuel production especially. Results Five surfactants were tested for its ability to control bio-contaminations in Chlorella culture. All five surfactants were able to eliminate the contaminants at a proper concentration. Particularly the minimal effective concentrations of sodium dodecyl benzene sulfonate (SDBS) to completely eliminate Poterioochromonas sp. and Hemiurosomoida sp. were 8 and 10 mg L−1, respectively, yet the photosynthesis and viability of Chlorella was not significantly affected. These results were further validated in Chlorella mass cultures in 5, 20, and 200 m2 raceway ponds. Conclusions A chemical method using 10 mg L−1 SDBS as pesticide to control predatory flagellate or ciliate contamination in Chlorella mass culture was proposed. The method helps for a sustained microalgae biomass production and utilization, especially for biofuel production.
