Protease is the main enzyme of detergent. Through the combination of different proteases and the combination of protease and detergent additives, it can adapt to different washing conditions to improve the washing effect. In this experiment, whiteness determination, microscope scanning, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy were used to detect the whiteness values of the cloth pieces before and after washing, as well as the stain residue between the fibers on the surface of the cloth pieces. The protease detergent formula with better decontamination and anti-deposition effects was selected. The combination of alkaline protease, keratinase, and trypsin was cost-effective in removing stains. Polyacrylamide gel electrophoresis showed that the molecular weight of the protein significantly changed after adding the enzyme preparation during washing, and the molecular weight of the protein was directly proportional to protein redeposition. The composite protease had a better comprehensive decontamination effect, and when compatible with suitable surfactants, anti-redeposition agents, and water-softening agents, the compound protease detergent exhibited a stronger decontamination ability than commercial detergents.Keywords:protease;detergent;surfactant;cleaning

Here, we bridge the gap between carbon mineralization and laundry detergent builder with sodium oxalate. Daily laundry can help mineralize carbon dioxide. First, we screen an environment-friendly process to produce sodium oxalate, using CO 2 as a raw material. Then, we evaluate the properties of sodium oxalate as a detergent builder and prove the formation of calcium oxalate under laundry conditions. Our data suggest that sodium oxalate has excellent calcium-removing properties. Detergents based on sodium oxalate have good detergency. Furthermore, solid calcium oxalates (calcium oxalate monohydrate or calcium oxalate dihydrate, which has good stability in water and thermal stability), is obtained from washing waters. These results demonstrate the possibility of using sodium oxalate as detergent builder. The whole process can transform the greenhouse gas CO 2 into commodity chemicals and can mineralize carbon.

A series of novel hydroxylated cardanol quaternary ammonium salts (HCQAS 3a–3g) with one or two hydroxyl groups, derived from renewable cardanol, a plant-based and low-cost material natural cashew nut shell liquid (CNSL), have been rationally designed and investigated as additive in detergent. CMC, γ CMC , C 20 , pC 20 , and CMC/C 20 were employed to exhibit the surface properties of HCQAS, reflecting that the surfactivity were superior to general cationic surfactants. In addition, HCQAS revealed excellent water solubility and wettability by krafft point and contact angle tests. Moreover, emulsifiability and foamability conversions were monitored versus time and volume of foam, respectively. Also, TEM micrographs were taken to provide the aggregation morphologies of HCQAS 3a aqueous solution at different concentration. Furthermore, HCQAS 3a and BGF-10 binary composite system as well as HCQAS 3a, BGF-10, and SDBS ternary composite system were investigated by CMC, γ CMC , emulsifiability, and foamability to determine the optimum molar ratio (HCQAS 3a: BGF-10: SDBS = 0.24:0.36:0.4), and then, analysis of morphology by TEM showed that the incorporation of HCQAS 3a, BGF-10, and SDBS in aqueous solution accelerated the formation of abundant vesicles with large volume and surface area. Finally, a green concentrated detergent was designed and prepared with the filtered ratio, where the presence of vesicles greatly enhanced detergency to promisingly replace the familiar use of petroleum-based TX-10 in detergent. This study on the structure and performance of HCQAS may shed some light on the development of novel environmentally friendly surfactant.

Cold-adapted, alkali-stable lipases with surfactant tolerance are highly sought after in the detergent industry. In this study, we recombinantly expressed and characterized a novel lipase from Marinobacter nanhaiticus (MNL). The purified MNL exhibited high stability within a temperature range of 10–30°C and pH values of 8–10, demonstrating optimal activity at 20°C and pH 8. MNL has a preference for substrates with medium chains with the best activity being 3768.6 U/mg using p -nitrophenyl decanoate as a substrate. Remarkably, MNL showed enhanced enzymatic activity in the presence of ionic surfactants and displayed notable resilience when exposed to proteases. Washing performance analysis further revealed MNL's high proficiency in removing oil-based stains from fabrics. Collectively, these results suggest that MNL holds significant promise as a valuable component in laundry detergent formulations.

The builder is an important ingredient in detergents. Sodium oxalate is a good non-phosphate detergent builder, which has good calcium-removing properties and good wash performance in detergents. However, sodium oxalate-based detergent formulations face a tricky problem of “incrustation” on fabrics due to calcium oxalate deposition. If sodium oxalate is used in commercial detergents, then “incrustation” must be solved. In this study, we examined the effect of fabric type, anionic surfactant, polymer, and temperature on incrustation and soil redeposition (“secondary” washing effect) of a sodium oxalate-based detergent. The results showed that both the anionic surfactant and polymer influenced the deposition of calcium oxalate on fabrics. Overall, the amount of calcium oxalate deposition followed the order polyamide < polyester < cotton with the same formulation. Finally, good secondary washing effects (low ash deposition and high whiteness retention) formulations were selected by cumulative washing. The formulation of methyl ester sulfonate (MES)-sodium carboxymethyl cellulose (CMC), MES-polyvinyl pyrrolidone, and alcohol ether sulfate (AES)-CMC had better secondary effects, and the optimal combination of the 12 formulations was AES-CMC.

Pesticide residues on vegetables could be removed by commercial detergents to guarantee food safety, but the removal efficiencies of different formulations of detergents need to be further investigated. In this work, surface enhanced Raman scattering (SERS) imaging method due to its good space resolution as well as high sensitivity is used to track the thiram residue, and evaluate the pesticide removing efficiencies by mixtures of several surfactants at different ratios. Sodium linear alkylbenzene sulphonate-alkyl glycoside (LAS-APG) with the ratio at 5:5 and the concentration at 0.2 % show the best removing effect. In addition, HPLC method is employed to validate the results of SERS imaging. Furthermore, LAS-APG mixture could be efficiently washed out from the leaves through simple household cleaning, meaning no secondary contamination. It is perspective that SERS imaging is an effective technique to explore the effect of fruit and vegetable detergents in removing pesticide residues.

Chemical detergents are extensively used to remove pesticide residues and foodborne pathogens on fresh fruits, but their residues are toxic to humans. To address this issue, a dual-functional starch copolymer, specifically dialdehyde starch-grafted ε-polylysine copolymer (DIA-ε-PL starch), was synthesized utilizing native starch with surfactant properties and the natural antimicrobial cationic peptide ε-polylysine (ε-PL). The effectiveness of DIA-ε-PL starch as a fruit detergent was subsequently evaluated. Raman imaging and HPLC results indicated that the removal efficiency of chlorothalonil (CHT) reached 96.62% under the optimal conditions which involved washing apples with a 1% corn-DIA-0.16-ε-PL solution at 30°C for 15 min. Compared to traditional washing reagents, DIA-ε-PL starch not only exhibited higher CHT removal efficiency without migrating into apple tissues but also demonstrated superior antibacterial effect against S. aureus (94.64%) and E. coli (98.78%). The DIA-ε-PL starch exhibits significant potential as a fruit-specific detergent due to its non-toxicity, economy, sustainability, and eco-friendliness.

Nuclear facilities generate lots of contaminated stainless steel metallic material during maintenance and decommissioning. As a new radioactive decontamination method, the self-embrittle decontamination method has the advantage of less secondary contaminants and being able to operate machinery remotely. Adding a certain amount of corrosive components to the self-embrittle compound detergent can achieve the dual functions of self-embrittlement and corrosive decontamination. It was used to optimized the response surface methodology (RSM) and train and evaluate four different machine learning models by the recorded data set. The purpose of the analysis was to quantify the accuracy of the corrosion decontamination effect of RSM model and four types of machine learning model. The results exhibits that the long short-term memory neural network (LSTM) model performs well. The prepared detergent can achieve the average corrosion depth of 5.9454 μm on stainless steel, which can satisfy the corrosion decontamination of radioactively contaminated stainless steel surfaces.

A psychrophilic extracellular protease was isolated from the marine bacterium Planococcus sp. M7 found in the deep-sea mud of the Southern Indian Ocean. The mature protease is about 43 kDa and contains 389 amino acids. Sequence alignment revealed that the protease whose catalytic triad was comprised of Ser224, Lys249, and Gln253 contains a catalytic module belonging to the serralysin-type protease family 41, and displays 46.55% identity with the experimentally verified serine protease from Bacillus subtilis str. 168. The enzyme displayed an alkaline mesophilic preference with an optimum pH of 10.0 and an optimum temperature of 35 °C. The enzyme retained its activity from 5 to 35 °C and was resistant to repeated freezing and thawing, but was completely inactivated at 55 °C. Calcium ions had a protective effect against thermal denaturation. More than 60% of the maximum activity was retained at pH values in the range of 5.0–11.0. Almost no activity loss was detected after 1 h of incubation at pH 8.0–10.0 and 20 °C, or with 1.0% SDS. Most important, this protease also showed good stability and compatibility with the standard enzyme-free detergent, which indicates its special interest for applications in detergent industry.

Sodium lignosulfonate (LS) was modified by polypropylene glycol diglycidyl ether (PPGDE) for the preparation of a surfactant (GLS), and firstly used for detergent builder. The effects of PPGDE content on the reaction and the properties of GLS were investigated. The structure of GLS was studied by Fourier transform infrared spectra (FTIR), ultraviolet spectrophotometer (UV), and gel permeation chromatography (GPC). The surface tension, critical micelle concentration (CMC), emulsifying ability, lime soap dispersing power (LSDP), and detergency were characterized. The results showed that GLS had higher surface activity and better emulsifying ability, LSDP, and detergency than that of LS. After decolorized by H2O2, the whiteness retention value of decolorized LS on white cloth reached 91.9%, while that of decolorized GLS increased up to 99.4%. These results suggested that the decolorized GLS may provide a new perspective for detergent builders.

Decellularization techniques have been widely used as an alternative strategy to produce matrices for organ reconstruction. This study investigated the impact of a detergent-enzymatic decellularization protocol on the extracellular matrix integrity, mechanical properties, and biocompatibility of decellularized tracheal matrices from rabbits. The tracheas of New Zealand white rabbits were decellularized using a modified detergent-enzymatic method (DEM). Antigenicity, cellularity, glycosaminoglycan content, DNA content, histoarchitecture, and mechanical properties were monitored during processing. The surface ultrastructure of the matrix was examined by scanning electron microscopy (SEM). Bioengineered and control tracheas were then implanted in major histocompatibility complex-unmatched rats (xenograft) heterotopically for 7, 15, and 30 days. Structural and functional analysis was performed after transplantation. The results showed that seven cycles of decellularization removed most of the cells and eliminated antigenicity. Histological and molecular biology analysis demonstrated that most of the cellular components and nuclear material were removed. SEM analysis revealed that the decellularized matrices retained the hierarchical structure of the native trachea, and biomechanical tests showed that decellularization did not significantly influence the mechanical properties. Seven, 15 and 30 days after implantation, decreased ( p < 0.01) inflammatory reactions were observed in the xenograft models for decellularized matrices compared with control tracheas. No increases in IgM or IgG content were observed in rats that received bioengineered tracheas. In conclusion, this work suggests that seven cycles of the DEM generates a bioengineered rabbit tracheal matrix that is structurally and mechanically similar to native trachea. © 2014 Wiley Periodicals, Inc.

The development of zeolite catalysts for linear alkylbenzene production is of crucial importance in achieving green chemical processes for the detergent industry. In the present research, the fabricated beta zeolite catalysts exhibited extraordinary activity (73%) and selectivity of 2-LAB (85%) in the alkylation of benzene with 1-dodecene, which benefited from the open micropore-to-mesopore networks, exposed acid sites, and shape-selectivity of special topology of beta zeolites. The computer calculations revealed that both benzene and 1-dodecene can enter into the 12-MR channels of beta zeolites, in which 1-dodecene was adsorbed on the surface of 12-MR channels in the form of chemical adsorption, and the fixed 1-dodecene was attached to benzene combined with the matched pore size of 12-MR channels of beta zeolites to effectively produce the desired 2-LAB. Moreover, the mesopore beta zeolites also presented superior stability compared with traditional micropore beta zeolite in the alkylation between benzene and 1-dodecene due to enhanced diffusion. Our work definitely paved a way to develop mesopore beta zeolites as a new type of highly efficient heterogeneous catalysts for industrial production of 2-LAB.
