The first detergent (or surface-active agent) was soap. In a strictly chemical sense, any compound formed by the reaction of a water-insoluble fatty acid with an organic base or an alkali metal may be called a soap. Practically, however, the soap industry is concerned mainly with those wat...
(c) neutral. (d) basic. Use the following terms to fill in the blanks: | Solvent | Base | Hydrophilic | Hydrophobic | Buffer | pH | Acid | Solute 1. Any substance that minimizes changes in the pH of a solution when an...
The above study can be appreciated more easily by reference to FIG. 2 wherein the acid-base neutralization of the present invention is apparent. All samples were neutralized to a pH between 6-6.5 using 10% sodium hydroxide. At base line there is relative chemical inactivity of 2-4 seconds ...
Textile material is bleached by impregnating it in a bath of inactive alkaline or neutral alkali chlorite, i.e. an alkali or alkaline-earth metal chlorite or ammonium chlorite, containing a potentially acid salt, i.e. a salt which, when dissolved in the alkaline or neutral chlorite bleaching ...
with vinegar solution and have added both vinegar and mild (30%) hydro choric acid to the water. I have left it for a week or more and repeated the process. However, as soon as I drain and change the water the ph shoots up. The water source is a neutral 7.It is now over a ...
[32] 32. Fatty acid ethoxylates with 2-40 ethylene oxide per fatty acid where the fatty acid has a carbon chain from C8-C18. [33] 33. The preferred detergents will use nonionic surfactants which include dinonylphenol ethoxylates or alkanolamides either alone or in mixtures with other nonionic...
A method for processing exposed and developed photographic silver dye-bleach materials, in which the exposed and developed material is treated with aqueous bleaching preparations which contain (a) an acid component, (b) a silver complexing agent, (c) one or more bleach catalysts, (d) optionally...
which in the presence of water releases carbon dioxide and/or oxygen with effervescence, with the solid base material comprising at least one component phase having an acid or a neutral pH in aqueous medium and at least one inorganic persalt bleaching agent incorporated therein being a ...
which in the presence of water releases carbon dioxide and/or oxygen with effervescence, with the solid base material comprising at least one component phase having an acid or a neutral pH in aqueous medium and at least one inorganic persalt bleaching agent incorporated therein being a ...
Aqueous bleaching agent suspensions based on a water-soluble peroxycarboxylic acid suspended in a carrier liquid in the presence of an organic thickening agent and of an acidifying agent exhibit an improved storage resistance over known suspensions with this base. This is achieved by means of pour...
