A Purified Alkaline and Detergent-Tolerant Lipase from Aspergillus fumigatus with Potential Application in Removal of Mustard Oil Stains from Cotton Fabric Tenside Surfactants Deterg. (IF 1.058) Pub Date : 2021-11-21 Akshita Mehta, Aashna Gupta, Kamal Kumar Bhardwaj, Reena Gupta
In the present study, the lipase from Aspergillus fumigatus was purified which was found to be stable to commercial detergents and oxidising agents. A purification fold of 6.96 and yield of 11.03% were achieved when the enzyme was purified using Octyl Sepharose column chromatography. In presence of various oxidizing agents, the highest activity of lipase was 15.56 U/mg with hydrogen peroxide. Among

Micellar-Enhanced Spectrofluorimetric Method for Quantification of Diclofenac Potassium in Pure Form, in Pharmaceutical Preparations and Human Plasma Tenside Surfactants Deterg. (IF 1.058) Pub Date : 2021-11-01 Muhammad Naeem Khan,Irum,Saba Gul,Muslima,Muhammad Mursaleen
Abstract A rapid, simple and economical spectrofluorimetric method for the determination of diclofenac potassium in pure form, in pharmaceutical preparations and in human plasma has been developed. The method is based on the enhancement of the fluorescence signal of diclofenac potassium by the addition of sodium dodecyl sulphate in McIvaine buffer with a pH of 5. Different experimental conditions such

Activity of Polyphenoloxidase in red Fuji Apples Promoted with Cationic Surfactant – Role of Surfactant Structure Tenside Surfactants Deterg. (IF 1.058) Pub Date : 2021-09-25 Maozhang Tian, Fan Zhang, Lu Wang, Xing Dong, Lifei Zhang, Xia Guo
In this study, we observed the activity of polyphenoloxidase (PPO) in red Fuji apples in the presence of single-chained surfactants (including cetyl trimethyl ammonium bromide (CTAB), and dodecyl trimethyl ammonium bromide (DTAB)) and gemini surfactants (pentamethylene-α,ω-bis(dodecyl dimethyl ammonium bromide), octamethylene-α,ω-bis(dodecyl dimethyl ammonium bromide, dodecamethylene-α,ω-bis(dodecyl

Evaluation of the Quality of Bath Cosmetics in Powder Form Depending on the Selection of Fillers Tenside Surfactants Deterg. (IF 1.058) Pub Date : 2021-09-25 Ilona Podkowa-Zawadzka, Tomasz Wasilewski, Małgorzata Zięba
The aim of the study was to evaluate the effects of hydrophilic microcrystalline cellulose, hydrophobic talc and mixtures of cellulose and talc when used as fillers in powdered bath cosmetics. A number of model formulations were developed that contained fillers in different compositions. Prototypical formulations were prepared and evaluated for their functional properties and skin-drying effect. An

Performance Evaluation of the Percarbonate and Perborate Bleach Activators Synthesized by a Low-Cost, Two-Step Method from Phenol Tenside Surfactants Deterg. (IF 1.058) Pub Date : 2021-09-25 Omid Shojaei
Bleach activators decrease the energy consumption and fabrics damage in the process of laundry and industrial cotton bleaching. Herein, we demonstrate a low-cost, two-step method for the synthesis of sodium nonanoyloxybenzene sulfonate and sodium lauroyloxybenzene sulfonate from phenol as a simple precursor material for efficient bleach activators. Initially, phenol was sulfonated to sodium p-phenolsulfonate

Synthesis and Aggregation of Novel Sugar-based Gemini Surfactants in Aqueous Solution Tenside Surfactants Deterg. (IF 1.058) Pub Date : 2021-09-25 Ruijuan Wang, Yu Lei, Zikun Mei, Dong Wang, Zhigang Yin
Novel sugar-based gemini surfactants with a 1,3-propan-2-ol spacer (1, 3-(N- alkyl-2-D-glucosaminyl acetyl) propan-2-ol, Glu(n)-3(OH)-Glu(n), n = 12, 14) were synthesized with D-(+)-glucono-1,5-lactone as starting material in two steps, whose structures were confirmed using proton nuclear magnetic resonance spectroscopy (1H NMR) and carbon nuclear magnetic resonance carbon spectroscopy (13C NMR). The

Hygiene in Commercial Dishwashing – A Review about the State of Knowledge in Research, Standardization, Regulation and Market Information Tenside Surfactants Deterg. (IF 1.058) Pub Date : 2021-09-25 Sarah Schulze Struchtrup, Britta von Esmarch-Rummler, Rainer Stamminger
The current state of knowledge about hygiene (efficacy testing) in commercial dishwashers will be collated in this review. Therefore, studies about hygiene in commercial dishwashing are summarised and existing standards, guidelines and the legislative basis described. Finally, examples of information available from the market, for example, detergents are presented. The use of bioindicators contaminated

Weakening of the Transdermal Effect of p-Phenylenediamine Pigments by the Temperature-Sensitive Poloxamer Sodium Alginate Gel Tenside Surfactants Deterg. (IF 1.058) Pub Date : 2021-09-25 Haiyan Gao, Yue Zhou, Jianguo Wang, Hujun Xu
A temperature-sensitive hair dye was prepared with a poloxamer-sodium alginate mixture. When the hair dye was applied to the hair (< 32 °C), it retained its flow dynamics. The hair dye was able to undergo a phase change and formed a solid as soon as it touched the scalp (32°C), which reduced the transdermal amount of p-phenylenediamine (PPD) and also adverse effects and toxicity. Compared to a conventional

Effect of Oxyethylene Groups of Fatty Alcohol Polyoxyethylene Ether Sodium Sulfates on Equilibrium and Dynamic Surface Tension in Relation to Wetting Properties Tenside Surfactants Deterg. (IF 1.058) Pub Date : 2021-09-25 Xiaodan Ren, Ping Li, Jianbo Li, Xiaoyi Yang, Chaohua Guo, Quanhong Li
The effect of hydrophilic chain of surfactants fatty alcohol polyoxyethylene ether sodium sulphates (AEnS, n = 2, 3, 7) on surface properties and wetting properties was investigated by the measurement of equilibrium surface tension, dynamic surface tension and dynamic contact angle. The fatty alcohol polyoxyethylene ether sodium sulphates with different head group sizes were used. From the results

Interaction of Surface Active Drug Promethazine Hydrochloride with Surfactants: Drug Release from Microemulsions Tenside Surfactants Deterg. (IF 1.058) Pub Date : 2021-09-25 Manoni Kurtanidze, Tinatin Butkhuzi, Irma Tikanadze, Rusudan Chaladze, Manuchar Gvaramia, Ketevan Nanobashvili, Maka Alexishvili, Polina Toidze, Marina Rukhadze
The interaction of surface-active drugs with surfactants, used in the simulation of artificial membranes by direct and reversed micelles, mainly determines the transport of drugs in the body and the complex process of the binding to receptors. Besides, the delivery of drugs into the body via microemulsions has been successfully used to reduce the first-pass metabolism. The structure of mixed reverse
