amine oxide in bleach

It is an effective agent for coupling nonionic surfactants with liquid, alkali detergent systems. Preferred are dodecyldimethylamine and tetradecyldimethylamine. Larger droplets are not buoyant in air and tend to drop out more quickly, lessening the possibility that the consumer can breathe it.

Amine oxide products containing mixtures of two or more such amine oxides are also suitable. It is compatible and stable in concentrated electrolyte solutions and is water soluble. 10. Most consumers are aware that hypochlorite bleach can also be used as a disinfectant. Table C.3.10. Significant amounts of nitrosoamines can be produced if the reaction is allowed run to completion or to near completion at the high temperatures taught in U.S. 4,247,480. Chemphos™ TC-227 is a detergent, emulsifier, wetting agent and coupling agent. In addition, this invention provides a process by which such cleaning formulations can be formed.

It has been found that a good balance between surfactant function and destabilization/depletion of the bleaching agent is achieved when the weight ratio of the bleaching agent to tertiary amine oxide product is within the range of from 0.33:1 to 30: 1, and preferably within the range of from 0.4: 1 to 10: 1. The integrated Ca2+ currents induced by three typical agonists NMDA, L-glutamate and L-CCG-IV were obtained at concentration of 50 μM, where the integrated currents for all the agonists reached their saturated values. The POE chains are subject to peroxidation and breakdown so that solutions should only be used when relatively freshly prepared; moreover, when using commercial sources one should be aware that antioxidants are sometimes included. Other features of this invention will become apparent in view of the following description of various embodiments of this invention. The hydrogen peroxide concentration in the cleaning formulation can be adjusted downwardly by employing an enzyme, such as catalase, in the formulation. These products are usually the best at bleaching the black stain on a surface due to mold growth. Also, at this time, there will be present unreacted hydrogen peroxide and carbon dioxide. To study this, the author used SLS with a CMC of 7.8 mM and AEOS-6EO (a C12 alkyl sulfate with 6 ethoxylate units) with a CMC of 0.4 mM. The authors claimed that their method is able to detect Ca2+ permeation with a detection limit of approximate to 105 Ca2+ ions/sec [96].

The superior thickening properties of Schercomid™ SL-EX fatty acid diethanolamide makes it suitable as an emulsion stabilizer for oil-in-water emulsions when using ethoxylated alkyl-phenols or ethoxylated aliphatic alcohols as the primary emulsifier. Both the amylose and amylopectin can recrystallize. With trifluoroacetic anhydride (Polonovski-Potier reaction, path b), a fragmentation of the carbon–carbon bond in the beta position of the good leaving group trifluoroacetate takes place, which is facilitated by the indolic nitrogen atom intermediate product B), producing iminium B which becomes iminium C to achieve equilibrium. It lacks any distinctive odor, as compared to the unpleasant scent of the hypochlorite. The only really effective way of removing the stain due to the mold pigmentation is bleach. These studies were performed in the 1970s, by Pierre Mangeney, carrying out his doctoral research, under Yves Langlois’ supervision, in Potier’s team133. It might be of interest here to recall that DR4 expression has shown correlation with tumour grade in invasive ductal carcinoma of the breast. NPN compounds account for a relatively high percentage of the total nitrogen in the muscles of some aquatic animals, 10–20% in teleosts, approximately 20% in crustaceans and molluscs, and 30–40% (and in special cases up to 50%) in elasmobranches. The process of claim 28 or 29 wherein the tertiary amine oxide product used contains, if any, no more than 1 ppm (wt/wt) of nickel and no more than 1 ppm (wt/wt) of iron. This is discussed in more detail in the section on the role of CMC. 9. The decrease in yield correlates with the increase in lateral pressure, which the lipid chains exert on the refolding protein. Gregory Szewczyk, Karen Wisniewski, in Handbook for Cleaning/Decontamination of Surfaces, 2007. This cooling can occur in a separate process vessel or can occur in drums in which the product will be shipped. [165] showed competition between betaine and SLS in their binding to skin callus. The process of any of claims 1-3 wherein the bleaching agent consists essentially of sodium hypochlorite, wherein the tertiary amine oxide consists essentially of tetradecyldimethylamine oxide, wherein the weight ratio of the bleaching agent to the tertiary amine oxide product is from 0.5: 1 to 5: 1, and wherein the formulation has a pH in the range of 12 to 13.5. This strategy of countering irritation potential using surfactant mixtures was investigated in more detail [159]. For example, bovine serum albumin catalyzes the eliminative ring opening of a benzisoxazole (Kemp elimination), β-elimination of 3-ketobutyl umbelliferyl ethers, a useful reaction in enzyme assays,78,79 moderately enantioselective oxidation of amines to amine oxides with sodium periodate,80 and the Morita–Baylis–Hilman reaction (Michael addition to form an enolate, followed by aldol addition) to couple cyclohexenone and p-nitrobenzaldehyde.81 Crude porcine pancreatic lipase catalyzed CC bond formation in ionic liquids, but enzyme purification revealed that protein impurities are the catalyst.82 Replacing crude porcine pancreatic lipase with bovine serum albumin also yielded the same reactions. A.M. Donald, in Encyclopedia of Materials: Science and Technology, 2001. So far as is known, nowhere in the prior art is the effect and significance of amine content on bleach performance of tertiary amine oxides recognized, let alone commented upon. These fish possess, in addition to the trimethyl, Handbook for Cleaning/Decontamination of Surfaces, It should be noted that the surfactants need to be hypochlorite stable, which greatly limits the choices. 30. This residence time on the surface can also give the cleaner time to disinfect the surface. Future strategies to produce even milder compositions need to explore ways to manipulate the free energy and/or thermodynamics of the system to shift more SLS into the micelle or alternatively to tie up the monomeric species as to block its action. The process of any of claims 1-3 wherein the bleaching agent used is sodium hypochlorite, and wherein the tertiary amine oxide used is an amine oxide product which contains from 28.5 to 32 wt% dodecyldimethylamine oxide, no more than 0.5 wt% dodecyldimethylamine, no more than 0.3 wt% hydrogen peroxide, and from 0 to 1 ppm nickel. Not only does TNF-α induce cell migration, but enhanced migration is also associated with reduced expresssion of E-cadherin and upregulated expression of vimentin (Chuang et al., 2008), features that characterise epithelial mesenchymal transition (EMT). The results presented in this work indicate that the function to generate ion gradients across membranes is a general property of archaeal rhodopsins (see Refs. It is one of the most frequently-used surfactants of this type. Such lysolipids and other zwitterionic detergents (e.g., sulfobetaines) have been used as well as highly dipolar groups (e.g., Tanahashi et al., 1985; Reid et al., 1988; Hasselbalch et al., 1992; Sax et al., 1996; Harris et al., 1999, Growth Factors and Their Receptors in Cell Differentiation, Cancer and Cancer Therapy, examined the effects of the anti-angiogenic NBBA [(Z)-N-(3-(7-nitro-3-oxobenzo[d][1,2]selenazol-2(3H)-yl)benzylidene)propan-2-, Surfactant Action on Skin and Hair: Cleansing and Skin Reactivity Mechanisms.

It is a significant feature of this invention that the tertiary amine oxide product contain a low level of amine impurity. They ascribed this synergism to interactions between the surfactants in solution, reducing the amount of either species available to elicit irritation.

To summarize the essence of these results, simply, let us take the example of the treatment of tropane N-oxide by acetic anhydride (Scheme 3.3) and of N,N-dimethyltryptamine N-oxide by trifluoroacetic anhydride (Scheme 3.4).
