Natural gums Sodium alginate Anionic 1-5 Water-dispersible 4-10 or 4-11.5 Pseudoplastic Incompatible with heavy-metal ions and sensitive to acids and ethanol in greater than 5%... 

Note Moderately polar, weakly hydrogen bonding solvent, heavy liquid gradually decomposes to acquire a yellow color, air and light will accelerate this decomposition nonflammable commercial product is often stabilized by the addition of 3 to 4% (mass/mass) alcohols highly toxic by ingestion, inhalation, and skin absorption soluble in alcohols, organohalogen compounds, hydrocarbons, benzene, and many oils incompatible with many alkali and alkaline earth metals. Synonyms tribromomethane. 

Violent reaction with benzoyl chloride combined with KOH, Bt2, barium carbonate, CS2, Cr(OCl)2, Cu, Pb, HNO3, BaCOs, H2SO4, hot water, (CH3)2S04, dibromomalononitrile, sulfuric acid. Incompatible with acids, ammonium chloride + trichloroacetonitrile, phosgene, cyanuric chloride, 2,5-dinitro-3-methylbenzoic acid + oleum, trifiuroroacryloyl chloride. Reacts with heavy metals (e.g., brass, copper, lead) to form dangerously explosive heavy metal azides, a particular problem in laboratory equipment and drain traps. When heated to decomposition it emits very toxic fumes of NOx and Na20. See also AZIDES. 

SAFETY PROFILE Moderately toxic by ingestion. Experimental reproductive effects. Incompatible with acids, alkaloidal and heavy-metal salts. When heated to decomposition it emits toxic fumes of Br and Na20. See also BROMIDES. 

The main aim of SAIE is the complete elimination of heavy metals from the coating systems an approach that primarily relies on tenacious water-insensitive adhesion and good barrier characteristics of a primer has been taken. It should be pointed out that this approach is theoretically incompatible with the approach that utilizes the primers with corrosion inhibitors, e.g., chromated primers. This is because a primer with super barrier characteristics would not allow the migration of inhibitors and would not provide enough water for their electrochemical reaction to form corrosion protection products, as described in Chapter 28. In order to further elucidate the SAIE concept, both chromated and nonchromated spray primers were employed to generate two types of plasma coating-modified systems, and their corrosion protection behaviors were investigated in this study. 

Some antioxidants possess antimicrobial properties, such as propyl gallate and butylated hydroxy anisole, which are somewhat effective against bacteria. Butylated hydroxy toluene has demonstrated some antiviral activity. Compatibility of antioxidants with the drug, packaging system and the body should be studied carefully. For example, tocopherols may be absorbed onto plastics ascorbic acid is incompatible with alkalis, heavy metals, and oxidizing materials such as phenylephrine, and sodium nitrite and propyl gallate forms complexes with metal ions such as sodium, potassium and iron. 

Incompatible with alkalis, heavy metal ions, especially copper and iron, oxidizing materials, methenamine, phenylephrine hydrochloride, pyrilamine maleate, salicylamide, sodium nitrite, sodium salicylate, theobromine salicylate, and picot-amide. Additionally, ascorbic acid has been found to interfere with certain colorimetric assays by reducing the intensity of the color produced. ... 

Incompatible with aluminum, calcium, heavy metals, iodine solutions, perchloric acid, and oxidizing agents. Oleic acid reacts with alkalis to form soaps. 

Sodium alginate is incompatible with acridine derivatives, crystal violet, phenylmercuric acetate and nitrate, calcium salts, heavy metals, and ethanol in concentrations greater than 5%. Low concentrations of electrolytes cause an increase in viscosity but high electrolyte concentrations cause salting-out of sodium alginate salting-out occurs if more than 4% of sodium chloride is present. 

Incompatible with quaternary compounds, gelatin, ferric salts, calcium salts, and salts of heavy metals, including silver, lead, and mercury. Preservative activity may be reduced by interactions with kaolin or nonionic surfactants. 

Sorbic acid is incompatible with bases, oxidizing agents, and reducing agents. Some loss of antimicrobial activity occurs in the presence of nonionic surfactants and plastics. Oxidation is catalyzed by heavy-metal salts. Sorbic acid will also react with sulfur-containing amino acids, although this can be prevented... 

Uethadone Hydrochloride, USP, Methadone hydrochloride. 6-(Dimethylamino)-4.4-diphenyl-3-heptanone hy-dnK hloride (Dolophine Hydrochloride), occurs as a bitter, white crystalline powder. It is soluble in water, freely soluble in alcohol and chloroform, and insoluble in ether. Methadone IS synthesized in several ways. The method of Easton et al. is noteworthy, in that it avoids the formation of the troublesome i.someric intermediate aminonitriles. The analgesic effect and other morphine-iike properties are exhibited chiefly by the (-) form. Aqueous solutions are stable and may be sterilized by heat for intramuscular and intrave-noas use. Like all amine salts, it is incompatible with alkali and salts of heavy metals. It is. somewhat irritating when injected subcutaneously. 

CALCIUM BROMIDE (7789-41 -5) Br2Ca Incompatible with strong oxidizers strong acids isocyanates, potassium, salts of heavy metals. Elevated temperatures cause this material to turn alkaline. Aqueous solution is a base incompatible with organic...
