what is an imulsifying agent?
452742
An emulsifying agent allows particles of a substance that isn't soluble in some solute to be held in suspension in that solute.\nThe classic oil and water (which do not stay mixed normally) can be held in suspension by adding an emulsifier which binds part of itself (not a permanent bonding but more of an attraction) to oil and another part of the same molecule to water. This acts as a 'bridge' allowing the less dense oil to stay in the water.

Hydrochloride\n\nFrom our old friend the Wikipedia:\n\nConverting otherwise insoluble amines into their hydrochlorides is a common way to make them water and acid-soluble. This is particularly desirable for substances used in medications. Many pharmaceutical substances used are prepared as hydrochlorides so that they may be quickly absorbed in the gastrointestinal tract.

Acetic acid\nCuprum\nNickel\nSodium chloride\nThere are many but common is D-glucose\nIsopropyl alcohol but accord to IUPAC it is 2-propanol\n\n\nWell in laundry detergents most commonly used element is hydrated sodium carbonate (Na2CO3.10H2O)

Insoluble amines can be made soluble by adding acid to the solution.  This forms the ammonium salt which is ionic and soluble.  Therefore the answer would be b, HCl.\n\nA similar strategy can also be used by adding base to carboxylic acids and phenols with low solubility.

Do you mean Aldara?  We use it quite a bit where I work.  We have had some localized reactions, but nothing systemic that I know of.\n\nAldara is the brand name for imiquimod which is an immune response modifier. Each gram of the 5% cream contains 50 mg of imiquimod in an off-white oil-in-water vanishing cream base consisting of isostearic acid, cetyl alcohol, stearyl alcohol, white petrolatum, polysorbate 60, sorbitan monostearate, glycerin, xanthan gum, purified water, benzyl alcohol, methylparaben, and propylparaben. Chemically, imiquimod is 1-(2-methylpropyl)-1H-imidazo>4,5-c@quinolin-4-amine. Imiquimod has a molecular formula of C14H16N4 and a molecular weight of 240.3.

A soap is a surface active agent, which  means it attaches to the surface of a substance or slightly alters the surface energy of the substance.  When two materials are brought into contact suchs as two liquids or a solid and a liquid, or two solids, the differences in the surface energies will determine whether the are immiscible or , in the case of solids, one wets the surface of another or simply beads up on it.  \n\nThe best "soap" needs to be chosen based on what the liquid chemistry is.  For example, if you want to mix a material in water or alcohol or oil.  Each could require a different "soap" to be used.

Lamisil.... it's an anit-fungal cream..... It goes good on toast.

The ingredient in the greater amount is called the solvent, so oil in water means there is more water. Water in oil, more oil.  An emulsion of oil and vinegar(5% acetic acid in water) is mayonnaise. Salad dressing that you have to shake up are emulsified for a short time. There are wall paints that are emulsions of oils and water. Whe you have a leaky head gasket in an car, oil gets into the radiator and makes a messy emulsion.

I think its actually called Picric Acid.\n\nIt is explosive.\n\nhttp://en.wikipedia.org/wiki/Picric_Acid

Sodium coceth sulfonate would be the sodium salt of sulfonated coconut oil.  Coconut oil is a mixture of trimyristin, trilaurin, tripalmitin, tristearin, and other glycerides.\n\nAs the previous poster indicated, it is a surfactant (detergent) used in shampoos, and is low toxicity and gentle on the skin and hair.

Aluminium Oxide (Al2O3) is insoluble in water but it is very slightly soluble in acids and alkalis. Aluminium Oxide is not only theoretical, it's used in applications including anti-refelective coatings, multilayers, interference films, protective films etc.

Probably insoluble detergents and inert ingredients.  It is impossible to tell without the exact ingredients which the manufacturers would not give.  My answer is based on the MSDS information.

I thought this would be easier to answer than it was.  I did finally find it in a reference titled Cosmetics Additives - An Industrial Guide.\n\n\nIt states:\n\ndl-alpha tocopheryl acetate\n-insoluble in water.\n-freely soluble in alcohol.\n-miscible with acetone, ether, chloroform, vegetable oils, etc
