摘要:
The invention provides a method for the preparation of a carrier liquid which comprises the steps of: (I) preparing a single phase solution comprising: (a) a solvent or a mixture of miscible solvents, (b) a liquid carrier material, which is soluble in solvent (a), and (c) a dopant material which is also soluble in solvent (a); (II) cooling (preferably freezing) the single phase solution produced in step (I) to a temperature at which at least both the solvent (a) and carrier material (b) become solid; and (III) removing solid solvent (a) from the cooled (frozen) single phase solution in vapor form, such that the remaining cooled (frozen) carrier material (b) and dopant material (c) are returned to ambient temperature thus providing a product of liquid carrier material (b) having dopant material (c) dispersed therein.
摘要:
Biocide compositions comprising biocide, surfactant, and solubilizing agent. The preferred biocide is parachlorometaxylenol. The biocide composition is useful in oil and gas drilling operations, such as hydraulic fracturing, as well as treating aqueous slurries in ore mining operations. The biocide compositions are effective in controlling microorganisms even in the presence of high salt content water and at high temperatures.
摘要:
Wiring devices that are manufactured by incorporating antimicrobial agents therein help eliminate or reduce any microorganisms that are present on the surface of the wiring device, and thus help prevent the spread of infection and disease from one person to another. By incorporating the antimicrobial agent into a resin mixture used for making wiring devices, the antimicrobial agent continues to leach out to the surface of the wiring device over time, resulting in a more effective, longer-lasting option than conventional cleaners. Methods of fabricating the wiring devices to include antimicrobial agents includes adding a prescribed amount of antimicrobial agent to a base material, mixing the agent and material to create a mixture, and extruding the mixture into one or more molds to form a wiring device of desired configuration.
摘要:
A liquid antiseptic composition containing ethanol, acetone, a quaternary ammonium comound, glycerine, and water which is rapidly germicidal, non-staining, and non-irritating to the human skin is disclosed.
摘要:
This invention provides an iodinated derivative of benzalkonium chloride having antiseptic activity combined with a lower toxicity than the corresponding chloride.
摘要:
Oral compositions useful for controlling dental plaque and gingivitis and for preventing caries are produced comprising a cationic antimicrobial agent and an anti-stain agent which reduces the staining effect of the cationic antimicrobial.
摘要:
DISCLOSED IS A METHOD INVOLVING THE EXPOSURE OF PLANTS AND PLANT PARTS TO A GROWTH REGULATING AMOUNT OF TETRAISOPENTYLAMMONIUM BROMIDE OR TETRAISOPENTYLAMMONIUM CHLORIDE, OR COMPOSITIONS THEREOF. SUCH PRACTICE IS PARTICULARLY USEFUL FOR THE REGULATION OF THE GROWTH PATTERN OF PLANT LIFE, PARTICULARLY AS EVIDENCED BY THE RETARDATION OF GROWTH AND ENHANCEMENT OF MATURATION.
摘要:
PRODUCTION OF MONOQUATERNARY AMMONIUM HALIDES BY REACTING TERTIARY AMINES WITH A,W-DIHALOALKANES HAVING MORE THAN 2 CARBON ATOMS OR WITH UNSUBSTITUTED OR SUBSTITUTED 1,2-DIHALOETHANES IN THE PRESENCE OF WATER AT 30 TO 150* C. THE HALOGEN COMPOUNDS, TERTIARY AMINES AND WATER ARE USED IN THE MOLAR RATIO OF FROM 0.5:1:0.1 TO 40:1:40. THE PRODUCTS ARE SUITABLE FOR REGULATING THE GROWTH HEIGHT OF PLANTS.
