Fire Fighting Procedures · 2건

WATER, FOAM, CARBON DIOXIDE, DRY CHEM

Water or foam may case frothing ... to liquids having flash points above 212 °F (100 °C) ... It does not indicate that water or fire fighting foam should not be used. The frothing may be violent and could endanger any fire fighters located too close to the burning liquid, particularly when solid streams of water are directed onto the hot, burning liquid. On the other hand, a carefully applied water spray has frequently been used to achieve extinguishment by deliberately causing frothing only on the surface of the liquid; the foaming action blankets the surface of the liquid and extinguishes the fire by excluding oxygen. This tactic is expecially successful with high viscosity liquids.

Storage Conditions · 1건

Salicylic acid should be stored in well-closed containers. Salicylic acid collodion should be stored in tight containers at 15-30 °C. Because the collodion is flammable, it should not be stored near heat or an open flame. Salicylic acid plaster should be stored in well-closed containers, preferably at 15-30 °C. The Trans-Ver-Sal plaster should be stored at a temperature less than 37.8 °C.

Salicylic acid was detected in the breast milk of 2 nursing mothers within 1 hour of aspirin (acetylsalicylic acid) ingestion; concns ranged from 0.2-1.5 and 0.27-1.0 mg/L(1). The salicylate ion was also detected in breast milk from 6 nursing mothers between the ages of 24 and 32 who ingested aspirin(1). Salicylic acid was measured in the serum of South Indians (0.05-0.64 umol/L), vegetarians (0.04-2.47 umol/L), nonvegetarians (0.02-0.20 umol/L), and aspirin takers (0.23-25.40 umol/L)(2).

The anti-inflammatory properties of salicylates and prednisolone were investigated using inhibition of in vitro phytohemagglutinin-stimulated lymphocyte proliferation in human whole blood from healthy male and female subjects. Steroids and salicylates are used in conjunction for the treatment of inflammatory disorders such as rheumatoid arthritis and inhibit the proinflammatory transcription factor, NFKB, by different mechanisms. Data generated using various combinations of these drugs were analyzed using isobolograms and the universal surface response approach based on the Loewe additivity principle. The interaction between aspirin and prednisolone was mildly antagonistic while that between salicylic acid and prednisolone was modestly synergistic at therapeutic concentrations. Further, aspirin was slightly more potent in males, but the nature of the steroid-salicylate interaction was similar across genders. This study helps rationalize part of the beneficial effects of steroids and salicylates in treatment of inflammatory disorders.

In rats, magnesium deficiency caused a moderate hearing loss, measured by means of evoked potentials at 10 and 20 kHz, which was repaired after refeeding a normal diet. Application of 700 mg/kg salicylic acid or injection of 5 x 100 mg/kg gentamicin also caused a reversible hearing loss in normally fed rats. Treatment of zinc deficient rats with salicylic acid produced a stronger although reversible hearing loss than in normally fed salicylate treated rats. Treatment of magnesium-deficient rats with gentamicin induced a strong hearing loss that was nearly complete and irreversible in 9 of 25 rats.

Environmental Fate · 4건

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 404(SRC), determined from a log Kow of 2.26(2) and a regression-derived equation(3), indicates that salicylic acid is expected to have moderate mobility in soil(SRC). The pKa of salicylic acid is 2.98(4), indicating that this compound will exist primarily in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Volatilization from moist soil surfaces is not expected to be an important fate process because anions do not volatilize. Salicylic acid is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 8.2X10-5 mm Hg(6). Salicylic acid has been observed to biodegrade quickly under differing sets of agricultural practices in Pahokee muck soil(7), suggesting that biodegradation in soil is an important fate process(SRC).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 404(SRC), determined from a log Kow of 2.26(2) and a regression-derived equation(3), indicates that salicylic acid is expected to adsorb to suspended solids and sediment(SRC). A pKa of 2.98(4) indicates salicylic acid will exist almost entirely in anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(5). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). In aqueous biodegradation screening tests, salicylic acid reached 88.1% of its theoretical biological oxygen demand after 14 days(8), suggesting that biodegradation in water is an important fate process(SRC).

AQUATIC FATE: Half-lives of 30 to 142 days have been calculated(SRC) for the photochemical reaction of salicylic acid and the salicylate with hydroxyl radicals in full intensity sunlit natural waters(1-3). Limited evidence suggests that salicylic acid, via photochemical processes, is involved in polymerization of fulvic acids in natural waters(4). The pseudo-first order rate constant for the direct photolysis of aqueous salicylic acid has been reported to be <0.02 hr-1(5).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), salicylic acid, which has a vapor pressure of 8.2X10-5 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase salicylic acid is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 30 hours(SRC), calculated from its rate constant of 1.3X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase salicylic acid may be removed from the air by wet or dry deposition(SRC). Salicylic acid contains chromophores that absorb at wavelengths >290 nm and therefore may be susceptible to direct photolysis by sunlight.(4).

Food Survey Values · 1건

Salicylic acid occurs in common fruits such as apples, oranges, plums, and grapes, which accounts for its presence in most wines(1). Salicylic acid has been quantitatively detected in many foods, including whole tomatoes, cinnamon, oregano, thyme, red wine, beer, honey, licorice, and raisins(2). A salicylic acid concentration of 1474.7 mg/100 g was measured in cumin, while other common spices contained up to 23.3 mg/100 g salicylic acid(3). Salicylic acid has also been detected in the blueberry Vaccinium arctostaphylos(4) and barley(5). A survey of vegetable soup found that the organic soup tested had a median salicylic acid concentration of 117 ng/g salicylic acid, while the non-organic soup had a median concentration of 20 ng/g(6).

Pharmacodynamics · 1건

Salicylic acid treats acne by causing skin cells to slough off more readily, preventing pores from clogging up. This effect on skin cells also makes salicylic acid an active ingredient in several shampoos meant to treat dandruff. Use of straight salicylic solution may cause hyperpigmentation on unpretreated skin for those with darker skin types (Fitzpatrick phototypes IV, V, VI), as well as with the lack of use of a broad spectrum sunblock. Subsalicylate in combination with bismuth form the popular stomach relief aid known commonly as Pepto-Bismol. When combined the two key ingredients help control diarrhea, nausea, heartburn, and even gas. It is also very mildly anti-biotic.

Mechanism of Action · 2건

Salicylic acid directly and reversibly inhibits COX-1 and COX-2 to decrease conversion of arachidonic acid to precursors of prostaglandins and thromboxanes. Salicylate's use in rheumatic diseases is due to it's analgesic and anti-inflammatory activity. Salicylic acid is a key ingredient in many skin-care products for the treatment of acne, psoriasis, calluses, corns, keratosis pilaris, and warts. Salicylic acid allows cells of the epidermis to more readily slough off. Because of its effect on skin cells, salicylic acid is used in several shampoos used to treat dandruff. Salicylic acid is also used as an active ingredient in gels which remove verrucas (plantar warts). Salicylic acid competitively inhibits oxidation of uridine-5-diphosphoglucose (UDPG) with nicotinamide adenosine dinucleotide (NAD) and noncompetitively with UDPG. It also competitively inhibits the transferring of the glucuronyl group of uridine-5-phosphoglucuronic acid (UDPGA) to a phenolic acceptor. Inhibition of mucopoly saccharide synthesis is likely responsible for the slowing of wound healing with salicylates.

Salicylic acid has a potent keratolytic action and a slight antiseptic action when applied topically to the skin. In low concentrations, the drug has keratoplastic activity (correction of abnormal keratinization) and in higher concentrations (i.e., 1% or higher, depending on the vehicle), the drug has keratolytic activity (causes peeling of skin). Salicylic acid softens and destroys the stratum corneum by increasing endogenous hydration (water concentration), probably because of decreased pH, which causes the cornified epithelium (horny layer) of the skin to swell, soften, and then desquamate.

Metabolism/Metabolites · 6건

Salicylic acid is extensively metabolized.

At low dosage, approximately 80% of salicylic acid is metabolized in the liver. Conjugation with glycine, forms salicyluric acid and when conjugated with glucuronic acid, acyl and phenolic glucuronide are formed. Small amounts of salicylic acid are also hydroxylated to gentisic acid. With large doses, the kinetics switch from first order to zero order.

Dogs were dosed intravenously with 1 g (14)C-salicylic acid (containing 10 uCi) in sodium bicarbonate solution. Urine was collected for 30 to 36 hours. Urinary metabolite recovery from one animal, which was representative of all the dosed animals, was 50% unchanged salicylic acid, 25% glucuronates, 10% salicyluric acid, and 4% to 5% gentisic acid. Total recovery was > 90% of the dose.

The major urinary metabolites identified after topical administeration differ from those after oral salicylate adminisration; those derived from percutaneous absorption contain more salicylate glucuronides (42%) and less salicyluric (52%) and salicylic acid (6%).

개요Salicylic acid (from Latin salix, willow tree, from the bark of which the substance used to be obtained) is a mono hydroxy benzoic acid, a type of phenolic acid and a beta hydroxy acid. This colorless crystalline organic acid is widely used in organic synthesis and functions as a plant hormone. It is derived from the metabolism of salicin. In addition to being an important active metabolite of aspirin (acetylsalicylic acid), which acts in part as a prod rug to salicylic acid, it is probably best known for its use in anti-acne treatments. The salts and esters of salicylic acid are known as salicylates.

출처Unripe fruits and vegetables are natural sources of salicylic acid, particularly blackberries, blueberries, cantaloupes, dates, raisins, kiwi fruits, guavas, apricots, green pepper, olives, tomatoes, radish and chicory; also mushrooms. Some herbs and spices contain quite high amounts, although meat, poultry, fish, eggs and dairy products all have little to no salicylates. Of the legumes, seeds, nuts, and cereals, only almonds, water chestnuts and peanuts have significant amounts.

역사The Greek physician Hippocrates wrote in the 5th century BC about a bitter powder extracted from willow bark that could ease aches and pains and reduce fevers . This remedy was also mentioned in texts from ancient Sumer , Lebanon , and As syria . The active extract of the bark, called salicin, after the Latin name for the white willow (Salix alba), was isolated and named by the German chemist Johann Andreas Buchner in 1826. Raffaele Piria, an Italian chemist was able to convert the substance into a sugar and a second component, which on oxidation becomes salicylic acid. Salicylic acid was also isolated from the herb meadowsweet (Filipendula ulmaria, formerly classified as Spiraea ulmaria) by German researchers in 1839. While their extract was somewhat effective, it also caused digestive problems such as gastric irritation, bleeding, diarrhea, and even death when consumed in high doses.

제조 방법 · 2건

생산 방법Salicylic acid is biosynthesized from the amino acid phenylalanine. In Arabidopsis thaliana it can also be synthesized via a phenylalanine - independent pathway. Sodium salicylate is commercially prepared by treating sodium phenolate ( the sodium salt of phenol ) with carbon dioxide at high pressure (100 atm ) and high temperature (390K) -a method known as the Kolbe-Schmitt reaction. Acidification of the product with sulfuric acid gives salicylic acid : It can also be prepared by the hydrolysis of aspirin (acetylsalicylic acid) or methyl salicylate (oil of winter green) with a strong acid or base.

Prepared by heating sodium phenolate with carbon dioxide under pressure
