“…As shown in Table , soil removal of CGK and CGN surfactants was found to be 85.9% and 86.5% respectively. This result indicates that both CGK and CGN show better detergency than LAS and oleyl dioleylamidoamine methosulfate (AQ), where LAS and AQ surfactants showed soil removal of 70.2% and 14.7% respectively (Lee et al, ).…”

“…Owing to the amphiphilic behavior of surfactant molecules, surfactant molecules preferentially move to the air–liquid, air–solid, or liquid–liquid interface until the interface becomes completely saturated and thus cannot accept any more surfactant molecule (Lee et al, , ; Lim et al, ; Lim & Chung, ). During this process, the alignment of surfactant molecules at the air–water interface occurs through a sequence of following steps (Lee et al, , ): The dissociation of a micellar aggregate into monomers; a slow relaxation process with a lifetime of 10 −3 to 1 s. The molecular diffusion of surfactant monomers from a bulk solution to the air–water interface. The adsorption/desorption of surfactant molecules at the air–water interface. …”

“…As exhibited in Table , the primary biodegradability of CGK and CGN has been found to be 99.0% in both surfactant systems, indicating that both CGK and CGN possess excellent biodegradability. It has been reported that the surfactant can be used in detergent formulations if primary biodegradability evaluated based on KSM 2714 is higher than 90% (Lee et al, ). Therefore, the test result suggests that both CGK and CGN surfactants can be potentially employed in detergent applications.…”

“…As presented in Table , both values of LD 50 measured for CGK and CGN have been observed to be larger than 2000 mg kg −1 in both surfactant systems. This result suggests that both CGK and CGN surfactants are considered to be very mild when comparing with conventional surfactants widely employed in detergent formulations such as polyoxyethylene (9) lauryl ether (PLA) and dodecylbenzene sulfonic acid (LAS) since LD 50 values evaluated for PLA and LAS are reported to be 1.19 and 650 mg kg −1 respectively (Lee et al, ).…”

In this study, 2 types of amino acid‐based biosurfactants such as potassium cocoyl glycinate (CGK) and sodium cocoyl glycinate (CGN) were synthesized from coconut oil. Their chemical structures were identified using FT‐IR, 1H NMR, and 13C NMR spectroscopies. Characterization of their interfacial properties has shown that both CGK and CGN surfactants are surface‐active and effective in reducing interfacial free energy. Washing test results indicated relatively good detergency compared with surfactants commonly employed in detergent applications. From environmental compatibility tests, both CGK and CGN are found to be readily biodegradable, nontoxic, nonirritating, and very mild. In particular, the CGK surfactant was found to be more efficient in reducing interfacial free energy since a larger number of CGK molecules are preferentially adsorbed at the air–water interface due to higher hydrophobicity and larger mobility of CGK than CGN, indicating possible uses in detergent applications.

Microporous Zeolites as Catalysts for the Preparation of Decyl Glucoside from Glucose with 1-Decanol by Direct Glucosidation

Abstract:The catalytic properties of microporous zeolite catalysts were evaluated in the synthesis of decyl glucoside from glucose with 1-decanol by direct glucosidation. The effects of the acidic properties and pore structure of the zeolite catalysts on the glucose conversions and decyl glucoside yields were investigated. The conversions of glucose on the H + ion-exchanged FAU, MFI, and BEA zeolite catalysts were above 70%. The conversion increased with decreasing acid strength of the catalysts. The highest conversion and yield of decyl glucoside were exhibited on the H-FAU(3) zeolite catalyst. The catalytic activities were enhanced with increasing amounts of acid sites. The selectivity of decyl glucopyranoside increased with decreasing Si/Al values for the same zeolite catalysts. The pore structure of H-FAU zeolite would allow sufficient spatial restriction to produce decyl glucopyranoside through the isomerization of decyl glucofuranoside into decyl glucopyranoside in its extensive pore channels. The selectivities of the decyl glucoside isomers relied significantly on the restricted transition state to the primary products due to their pore topologies.

Enzymes can decrease the environmental and economic load of detergent products by reducing the amount of chemicals used in detergents and by allowing washing at ambient temperatures. In this study, Streptomyces cellulosae AU‐10 (GenBank accession number: MG780240) lipase was purified 7.08‐fold with 68% yield using an aqueous 2‐phase system. The Streptomyces sp. AU‐10 lipase showed maximal activity at pH 9.0 and 40 °C. Hundred percent activities were measured in the pH range from 9.0 to 11.0 for 1 h. The enzyme was also highly stable at 30–50 °C. The values of Km and Vmax were calculated as 0.34 mM and 0.83 mM min−1, respectively. The lipase has high hydrolytic activity for olive oil and sunflower oil. The effect of ethylenediamine tetraacetic acid on the enzyme has shown that the lipase is a metalloenzyme. The activity increased in the presence of Fe2+, Cu2+, and various boron compounds. The enzyme has shown a good stability not only with surfactants but also with oxidizing agents. In addition, activities in the presence of Omo, Ariel, Tursil, Pril, and Fairy were measured as 108.8%, 115.6%, 98.35%, 140.4%, and 107.6%, respectively. Considering its remarkable ability, the S. cellulosae AU‐10 lipase can be considered as a potential additive in the detergent industry.
