“…Fatty acid methyl ester sulfonates (MES) are oleochemical-based anionic surfactants, derived mainly from palm or coconut oil, obtained by a sulfonation reaction followed by acid digestion. MES, linear alkylbenzene sulfonates (LASs), alkyl sulfonates (ASs), and alpha olefin sulfonates (AOSs), are used as detergent surfactants [ 41 ]. MES comprises the sodium salts of the sulfonated methyl ester acids, such as lauric acid (sodium methyl laurate sulfonate), myristic acid (sodium methyl myristate sulfonate) palmitic acid (sodium methyl palmitate sulfonate) and stearic acid (sodium methyl stearate sulfonate).…”

“…LASs are fossil fuel-derived surfactants that can possess good bio-degradability and low ecotoxicity. However, due to the interest of detergent companies in natural fat- and oil-based surfactants, rather than those that are petroleum-based like LAS, MES are considered as a main laundry detergent ingredient with good surface-active properties as well as good biodegradability [ 23 , 41 , 42 , 43 ].…”

This article includes an updated review of the classification, uses and side effects of surfactants for their application in the cosmetic, personal care and pharmaceutical industries. Based on their origin and composition, surfactants can be divided into three different categories: (i) synthetic surfactants; (ii) bio-based surfactants; and (iii) microbial biosurfactants. The first group is the most widespread and cost-effective. It is composed of surfactants, which are synthetically produced, using non-renewable sources, with a final structure that is different from the natural components of living cells. The second category comprises surfactants of intermediate biocompatibility, usually produced by chemical synthesis but integrating fats, sugars or amino acids obtained from renewable sources into their structure. Finally, the third group of surfactants, designated as microbial biosurfactants, are considered the most biocompatible and eco-friendly, as they are produced by living cells, mostly bacteria and yeasts, without the intermediation of organic synthesis. Based on the information included in this review it would be interesting for cosmetic, personal care and pharmaceutical industries to consider microbial biosurfactants as a group apart from surfactants, needing specific regulations, as they are less toxic and more biocompatible than chemical surfactants having formulations that are more biocompatible and greener.

“…Fatty acid esters (FAEs), products resulting from the transesterification of triglycerides (TGs), are molecules with a wide number of applications. For instance, they are often used as an intermediate for the production of surfactants and plasticizers. , An example of such a derivative of FAEs includes fatty alcohols, a compound of high industrial importance. Annual production of fatty alcohols amounted to 3.1 million tons in 2015 .…”

Fatty acid methyl esters are extensively used compounds in the industry, but they are perhaps most widely known for their application as biodiesel. In this study, we propose the rotor–stator spinning disc reactor (RS-SDR) as an intensified reactor for the production of fatty acid methyl esters. The RS-SDR relies on the generation of high shear forces in the small gap of a disc, rotating at high speeds, and a stationary wall, to improve on mass and heat transfer rates. Here, we have illustrated the benefits of mass transfer intensification for this reaction by performing the homogeneous base-catalyzed reaction in both a single-stage and a scaled-up multistage RS-SDR. A high level of productivity could be obtained in the multistage reactor (7.78 × 103 mol mR –3 min–1 at a conversion of 82%). Furthermore, we also performed a heterogeneous transesterification reaction with calcined sodium silicate as a slurry catalyst. We were able to obtain a productivity of 214 mol mR –3 min–1 in the RS-SDR (72% conversion, with a residence time of 8 min). In comparison, the batch heterogeneous system had 47% conversion during the same time period of operation. The high slurry concentrations of up to 20 wt % (based on oil weight fraction) did not lead to clogging or fouling in the reactor. These results demonstrate the potential of the RS-SDR for the transesterification reaction.

“…These ME can be derived from vegetable oils such as palm oil, coconut oil, and soybean oil. In the initial stage of development, α-MES has been associated with a multitude of technical disadvantages mainly related to its poor solubility, tendency to hydrolyze, longer processing time, irritancy, dark color, and also the presence of skin-sensitized products (Tobori & Kakui, 2019). These undesirable properties of α-MES were back then created a fear factor for the detergent industry to scaleup the technology into large-scale production.…”

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.
