An astrignent is a chemical that tends to shrink or constrict body tissues, usually locally after topical medicinal application. The shrinkage or constriction is through osmotic flow of water (or other fluids) away from the area where the astringent was applied. Astringent medicines cause shrinkage of mucous membranes or exposed tissues and are ...The rate constant for the vapor-phase reaction of t-butyl alcohol with photochemically-produced hydroxyl radicals has been reported as 1.12X10-12 cu cm/molecule-sec at 25 °C (1). This corresponds to an atmospheric half-life of about 14 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm (1).PubChem Structure Search.

Propylene glycol is a synthetic liquid substance that absorbs water. Propylene glycol is also used to make polyester compounds, and as a base for deicing solutions. Propylene glycol is used by the chemical, food, and pharmaceutical industries as an antifreeze when leakage might lead to contact with food.CID 5360545 (Sodium) Sodium borohydride is a white to grayish crystalline powder. It is decomposed by water to form sodium hydroxide, a corrosive material, and hydrogen, a flammable gas. The heat of this reaction may be sufficient to ignite the hydrogen. The material itself is easily ignited and burns vigorously once ignited.In a group of 37 rotogravure printers a close correlation (rs = 0.78) was found between the time weighted toluene exposure during a five day working week (range 8-416 mg/cu m, median 75) and the concentration of toluene in subcutaneous adipose tissue (range 1.1-20.7 mg/kg, median 3.8).
