Cas No. :1310-73-2
Quantity: 1Metric Tons Specs:1kg/ foil bag with discreet packgae Price:1 USD Kilograms Payment Method: T/T, WesterN Union, Money Gram Ethyl p-hydroxybenzoate Chemical name: ethyl p-hydroxybenzoate ethyl hydroxybenzoate Name of commodity: ethyl p-hydroxybenzoate Molecular formula: C9H10O3 Molecular weight: 166.18 Properties: white crystal, taste bitter, Zhuo Ma, Yi Rong in alcohol, Almost insoluble in water, boiling point 297-298. Use: This product is mainly used in food, cosmetic, pharmaceutical preservatives, also used for feed preservative. Appearance: colorless crystal or white crystalline powder Content (dry basis)% :99% The melting point of :115-118 Sulfate (SO42-)% :0.024 Heavy metal (Pb)% :0.001 Arsenic (AS)% :0.0001 Residue on ignition%:0.05 Loss on drying%:0.5 Other Description: Nipagin ester is internationally recognized as efficient broad-spectrum food preservatives, the United States, Europe, Japan, Canada, South Korea, Russia and other countries are allowed to Nipagin Esters in food applications. Widely used in soy sauce, vinegar and other seasonings, pickled products, baking food, sauce product, beverage, wine and fresh fruit and vegetable fields. Nipagin Esters Containing Methyl Paraben, ethyl Paraben, Propyl Paraben, Butylparaben, octyl Paraben, Methyl Paraben sodium, sodium ethyl Paraben, Propyl Paraben sodium, sodium Butylparaben and compound sodium methylparaben, according to the physical and chemical properties of different application in anticorrosion of food, medicine, organic synthesis and other industries. Nipagin ester or parabens, because it has the structure of phenolic hydroxyl, so the anti bacteria performance ratio of benzoic acid, sorbic acid are strong. The mechanism of action is damage cell membranes of microorganisms, so intracellular protein denaturation, and can inhibit the microbial cells of respiratory enzymes and electron transfer enzymes activity. Antibacterial activity of Nipagin ester is the main molecular state action, and the intramolecular hydroxyl has esterification, no longer ionization, so it is in the antibacterial effect of pH3 ~ 8 range has very good. The benzoic acid and sorbic acid were acidic preservative bacteriostasis in their pH 5.5 products effect is very poor. Safety of Nipagin ester is very high, with ethyl ester as an example, the LD50 5000mg kg, ADI 0 ~ 10mg kg, LD50 2530mg and benzoic acid for kg, ADI for 0 ~ 5mg kg, LD50 7630mg kg, sorbic acid, ADI 0 ~ 25mg kg, since the amount of Nipagin Esters only sorbic acid, benzoic acid, 110 ~ 15, so the relative safety of sorbic acid is much higher than the. |
