Application of Amino Acid-Based Surfactant in Dishwasher Detergent

The application of amino acid-based surfactant in dishwasher detergent was studied in this paper. The foam and oil-removing performance of amino acid surfactants in alkaline condition were test to discuss feasibility of amino acid-based surfactant from natural origin as the alternative to traditional nonionic surfactants from petroleum origin in dishwasher detergent. Comparative study was conducted through using various amino acid-based surfactants and nonionic surfactants respectively, together with enzymes and peroxide to formulate dishwasher detergents, and their application properties such as foam performance and detergency were also evaluated when washing different tableware in automatic dishwasher. The results showed that among all tested amino acid surfactants, glutamate surfactants showed low foaming and high oil-removing ability in alkaline condition, and excellent decontamination ability in dishwashing tests.

Review of Regulations Related to Detergents for Auto-dishwasher

This paper summarized the regulations related to dishwasher detergents from four perspectives:cleaning performance,rinsing performance,energy and water consumption during usage,environmental and biological safety.Finally,the trend of detergents for auto-dishwasher has been summarized.

Formula Development of Special Detergent for Automatic Household Dishwasher

The composition of raw materials in the formula was determined by the fluidity and stability tests of the dishwashing powder.Enzymes,chelators and polymers were determined for the dishwashing powder formulated with specific materials.The detergency of the final formula was tested in laboratory and the feedback from consumers was also obtained,the results of which indicated that the dishwashing powder formula showed good detergency.

The Study on Application of Bio-enzyme in Dishwasher Detergents

Aiming at the kitchen stain and fast growth of dishwasher market in China,the addition of protease and amylase solution in the dishwasher detergents was proposed for the food stains typical in China.A comparison between Chinese commercial dishwasher detergents and an EU mainstream detergent was made.The results indicated that the addition of protease and amylase could significantly increase the washing performance,and thus could help close the washing performance gap between our products and the EU mainstream product.

Current Situation and Development Trend of Specific Detergents for Dishwasher in China

Abst The basic information of the mainstream dishwasher detergents in China market was sorted out.The product form,main components and functions of the dishwasher detergents were described.The future development trend of dishwasher detergents was discussed from the aspects of the product efficacy,form and concentration.Finally,some suggestions were put forward for the promotion of dishwasher detergents in China.

Preparation and Investigation of High-Efficiency Antibacterial Liquid Dishwashing Detergent

A high-effi ciency liquid dishwashing detergent was prepared by using oregano essential oil as an antibacterial agent. The surface cleaning and antibacterial property of the detergent resolved its unifunctionality problem. The antibacterial activities of the detergent were demonstrated through a disk diff usion assay and wipe experiments with Escherichia coli and Staphylococcus aureus . Results showed that the prepared detergent was highly eff ective against E. coli and S. aureus . The results of chemical accelerated tests indicated that the detergent would be eff ective for at least 1 year. The antibacterial property and detergency performance of the high-effi ciency antibacterial liquid dishwashing detergent were compared with those of a commercial antibacterial detergent containing 0.02% o -phenylphenol. The detergency performance of the high-effi ciency detergent reached 97.8% and was superior to that of the commercial antibacterial detergent.

Isolation of DNA from Saliva and Cheek Cells Using Household Chemicals

Saliva is a feasible specimen used in sample collection for research purposes.It is reported that saliva typically contains^430,000 epithelial cells per mL.There are various cost-effective methods and commercial kits available which are used to extract DNA from saliva.However,this study aims to explore a simple,time-saving and cheap method of DNA extraction using daily life household chemicals without the help of any electronic equipment.This protocol utilizes pineapple juice which contains bromelain enzyme as a proteolytic agent and dishwashing liquid as a detergent to rupture the cell membrane and remove the contamination.It takes approximately 10-15 min for the completion of extraction procedure.Results have indicated the good quality of DNA by gel electrophoresis and good yield with purity of 1.7-1.8 optical density.Thus,this method serves as a simple,convenient,easy-to-handle,time-saving,cheap and less laborious way for the extraction of DNA in daily routine practices with a good precision of quality and quantity that could be used for diagnostic purposes.

Test Method for Evaluating the Cleaning Performance of Proteases in Automatic Dishwashing Detergent

A test method was developed to better evaluate the cleaning performance of protease in Chinese automatic dishwashing detergent(ADD)and differentiate the washing performance of different ADD formulations on protein stains.Steamed egg stain,which was a Chinese-consumers-relevant soil,was used as monitor.The response curves of the stain to different amounts of protease were measured under laboratory conditions,and the stain removal ability of commercially available ADDs was tested with this method.The results showed that the soil removal rate of ADD without protease was less than 10%,and the soil removal rate increased with the increase of protease dosage in the range of 0~2.0%.Steamed egg stain had a good response to protease,and it could effectively distinguish the cleaning performance of commercial ADDs.The test method could be used in the development,screening and evaluation of ADD formulations.

Protection of Glassware in the Automatic Dishwashing Process – A Detergent Manufacturer’s Insights and Experiences

Since the automatic dishwasher became a very common household appliance,some negative surface modifications with dishes can happen.This paper is recapping main risk factors for glass and décor corrosion after long term washing in the dishwasher.The different possibilities for a detergent providing protection of glassware are pointed out.Additionally,the impacts on material care due to the US and EU-phosphate ban in dishwasher detergents are discussed.

Quantitative Evaluation Method of Amylase Performance in Detergents for Hand Dishwashing

An evaluation method was designed for reference in the experiment,which was further verified by investigating the changes of various factors,including additive amount of enzyme,washing temperature,soaking time,pH value and amylase source,etc.Based on tests and comparison,it is confirmed that this method can effectively and quantitatively evaluate the performance of amylase in detergents for hand dishwashing.
