Amorphous polyolefin bond well to nonpolar
substrates like polyethylene and polypropylene but are usually not recommended for polar surfaces.
Unlike silicone, fluorosilicone contains tri-fluoropropyl groups that enhance its chemical resistance to nonpolar
solvents, fuels, oils, acids and alkaline chemicals at temperatures between -70[degrees]F and 450[degrees]F.
9,956,148 B2; Shiseido Company, Ltd., Tokyo, has patented an oil-in-water emulsion cosmetic consisting of hydrogenated polyisobutene, higher alcohol, an oil component including nonpolar
oil, surfactant, water-soluble thickener selected from a group consisting of carboxyvinyl polymer, xanthan gum, methyl cellulose, dimethylacrylamide/sodium acryloyldimethyltaurine crosspolymer, sodium polyacrylate/sodium acryloyl dimethyl taurine copolymer and ammonium acryloyldimethyltaurine/VP copolymer, and an aqueous component.
First, all the nonpolar
phases and polar phase were melted together at 75[degrees]C.
Therefore, this study used three kinds of vegetable oil droplets to clarify the role of intermolecular forces of long carbon-chain molecules, especially the force that emerges from polar and nonpolar
Ant carcinogenic activity: A nonpolar
fraction of damong maria leaves containing terpenoids has been shown to cause a decrease of oncogenes in an oral epithelial carcinoma cell line demonstrating an ant carcinogenic activity.
Its advantage is its applicability to detect a wider range of byproducts of degradation, polar or nonpolar
The researchers also showed that this occurs because of competition between opposite effects, such as differences in the way titanium ions and zirconium ions want to move or stay in nonpolar
Using dielcometry for the calculated determination of the volume moisture content W of emulsions is based on the dependence of the dielectric constant [[epsilon].sub.eml] of a homogeneous emulsion of the <<liquid nonpolar
dielectric-water>> type on the moisture content and permittivity e[[epsilon].sub.nld]u of an anhydrous nonpolar
The selected solvents enable investigating the behaviour of the molecules in polar and nonpolar
[DELTA][G.sub.sol] is solvation-free energy and can be divided into two parts, the polar solvation-free energy ([DELTA][G.sub.p]) and the nonpolar
solvation-free energy ([DELTA][G.sub.np]).
