nonionic surfactants Examples of nonionic in a Sentence Recent Examples on the Web NBS Corning Corning, New York NBS – as in nonbinding surface – is a nonionic hydrophilic polymer coating that prevents traces of proteins, DNA, or drug compounds from sticking to test tubes or assay plates. ...
5.2.1Nonionic Surfactants Nonionic surfactantsare composed of two sections. The polar portion exhibits a strong affinity for polar solvents, particularly water, and it is often called thehydrophilic part. The nonpolar part is called hydrophobe from the Greek rootsphobos(fear). Examples of nonionic ...
surfactants, the counterions are defined by their method of making. Good examples are the carboxylic acid surfactants created by saponification (seesection 20.3.2.1). These usually carry an alkaline metal counterion, mostly Na+or K+. These are the most common counterions foranionic surfactants. ...
Further, tendency of these surfactants to improve antisoiling properties of shapes such as carpeting may be evaluated by the procedure described in the examples. The surfactant may be applied directly to the polymeric shape by any known method such as by means of a spray, by means of a bath...
The products are stable in concentrated aqueous solutions of inorganic salts and are useful as surfactants and agents for reducing surface tension. Examples and experimental results are given.ALSO:A compound of the formula in which one of the positions marked 1 and 3 is substituted by a nonyl ...
07054, can be consulted for further examples of nonionic surfactants usable in this invention. The clay used in the novel mixtures of this invention can be of any suitable type that has been mined and refined in conventional ways to filler, extender or pigment grade for paints or paper ...
Adjuvants constitute a broad range of substances, of which solvents and surfactants are the major types. Nonionic surfactants such as alcohol ethoxylates (AEOs) and alkylamine ethoxylates (ANEOs) are typically examples of pesticide adjuvants. In view of their chemical structure this paper outlines ...
The following description illustrates the manner in which the principles of the invention are applied but are not to be construed as limiting the scope of the invention. The following examples demonstrate the preparation of the polycarbonate type surfactants in accordance with the present invention. ...
EXAMPLES Example 1 Determining the Efficacy of Surfactants to Stabilize Water-In-Oil Emulsions An experimental vessel was constructed in order test the ability of various surfactants to stabilize water-in-oil emulsions. The experimental vessel was of a pipe construction that allowed the experiment to...
Stabilization of a non-aqueous self-double-emulsifying delivery system of rutin by fat crystals and nonionic surfactants: preparation and bioavailability study Literature examples of non-aqueous Pickering emulsions stabilized by fat crystals are very rare. Moreover, the applications of rutin are limited ...
