BACKGROUND A.I.S.E., the International Association for Soaps, Detergents and Maintenance Products, launched the 'A.I.S.E. Charter for Sustainable Cleaning' in Europe in 2005 to promote sustainability in the cleaning and maintenance products industry. This Charter is a proactive programme for translating the concept of sustainable innovation into reality and actions. Per product category, life c...

Triclosan (2,4,4'-trichloro-2'-hydroxydiphenyl ether) is a widely used antibacterial agent. However, it was concerned recently that triclosan might act as an antibiotic and will cause resistant bacterial strains. Furthermore, possible formation of toxic chloroform was also reported when the triclosan contained in household dishwashing soaps reacted with the chlorinated water. To assess the asso...

Membrane proteins (MPs) are usually handled in aqueous solutions as protein/detergent complexes. Detergents, however, tend to be inactivating. This situation has prompted the design of alternative surfactants that can be substituted for detergents once target proteins have been extracted from biological membranes and that keep them soluble in aqueous buffers while stabilizing them. The present ...

A crucial bottleneck in membrane protein studies, particularly G-protein coupled receptors, is the notorious difficulty of finding an optimal detergent that can solubilize them and maintain their stability and function. Here we report rapid production of 12 unique mammalian olfactory receptors using short designer lipid-like peptides as detergents. The peptides were able to solubilize and stabi...

Micellar complexes were prepared from bacteriochlorophyll a and bacteriopheophytin a with the cationic detergents, cetyltrimethyl ammonium bromide and cetylpyridinium chloride. These complexes have spectroscopic properties (absorption, circular dichroism) which are very different from the ones formed with non-ionic detergents like Triton X-100, and also with anionic detergents. Bacteriochloroph...

I t has been demonstra ted tha t in the green leaf chlorophyll is combined with protein by t rue chemical linkage. The chlorophyll-protein compound of the spinach leaf is insoluble in water and buffer solutions, bu t can be dispersed by detergents yielding bri l l iantly clear solutions. In addition to clarifying these solutions, the detergents denature the protein and change the absorption spe...

The action of synthetic detergents upon several strains of bacteriophage has been mentioned in a previous communication (Klein et al., 1945). With the exception of gamma coli phage, the bacteriophages tested were highly susceptible to the germicidal activity of the various test compounds. The gamma phage, on the other hand, proved to be resistant to the highest concentrations of the detergents ...

A procedure for the enzymatic determination of lecithin and sphingomyelin in aqueous solution is described. The phospholipids are first dissolved in chloroform:methanol (2:1 by vol), the solvent is evaporated, and the residue is redissolved in an aqueous zwitterionic detergent solution. The enzymatic reaction sequences of both assays involve hydrolysis of the phospholipids to produce choline, w...

Enzymes are important molecules that help chemical reactions in living beings happen faster and easier. Did you know enzymes present many products used our daily lives? detergents, pets’ food own food. Sponges live the oceans need from enzymes, too. Microscopic organisms make their homes on marine sponges, these microbial partners produce sponges with nutrient digestion! These useful can also b...
