Ascorbyl Palmitate CAS 137-66-6

The manufacturing and use ascorbyl palmitate as an antioxidant and also chemical preservative may lead to its launch right into the atmosphere with numerous waste streams. If launched to air, the estimated vapor stress at 25 ° C is 2.09X10-15 mmHg, suggesting that ascorbyl palmitate will certainly exist in the environment just in the fragment phase. The fragment stage ascorbyl palmitate will certainly be done away with from the environment by damp or dry deposition. Ascorbyl palmitate does not have a chromophore that takes in at > 290 nm along with is as a result anticipated to be much less vulnerable to photolysis by straight sunlight. If launched right into dust, ascorbyl palmitate is expected to be moderately mobile based upon an approximated Koc of 450. Volatilization from moist dirt surfaces is not prepared for to be a substantial destiny procedure based upon Henry’s estimated guideline constant of s 1.4X10-7 atm-cu m/mole. No biodegradation info conveniently available. If launched to water, based upon the approximated Koc, ascorbyl palmitate is anticipated to adsorb to suspended solids and likewise fragments.Volatilization from the surface area is not prepared for to be an essential fate treatment based upon the approximated Henry’s regulation constant for this material. An estimated BCF of 180 reveals a high opportunity for bioconcentration in water bacteria, offered the material is not metabolized by the microbe. The approximated base-catalyzed 2nd hydrolysis rate constant is 2.85X10-2 L/mole-sec, corresponding to half-lives of 7.7 years as well as additionally 280 days at pH 7 as well as 8, specifically. Work exposure to ascorbyl palmitate may arise from breathing and also facial exposure to the material in workplace where ascorbyl palmitate is created or made use of. Use information recommend that the basic people might be disclosed to ascorbyl palmitate via intake of food as well as additionally use medicinal items and also anti-oxidants having ascorbyl palmitate.
