Ascorbyl Palmitate Uses

  1. Ascorbyl Palmitate is used in oily foods, edible oils, pet and also vegetable oils, and also high-grade cosmetics. It can likewise be used in numerous infant foods and milk powders. It has anti-oxidation and also dietary strengthening features. It is made use of as an anti-oxidant bleaching representative for VE, and anti-oxidant in oils The effect is very noticeable and high temperature resistant. It is suitable for medication, health items, cosmetics, etc, and also it is additionally appropriate for the antioxidant of baking as well as frying oil. The antioxidant impact on lard is much better than that of grease.
    Ascorbyl Palmitate can be utilized as an antioxidant, as a fat-soluble anti-oxidant. It is suitable for usage in pet as well as vegetable oils and different foods. As an example, it has a considerable effect on supporting soybean oil, cottonseed oil, palm oil, unsaturated fat and also hydrogenated grease.
  2. Furthermore, KageyamaK et al. likewise situated that it can unquestionably prevent the DNA production of Ehrlichascites swelling cells and also liquify the cytoplasmic unsaturated fats of tumor cells, which is a great anti-cancer compound. It can be anticipated that L-ascorbyl palmitate will certainly come to be energetic as an expanding and also necessary intelligent chemical in various markets such as food, skin treatment products as well as healthcare items.

Ascorbyl Palmitate Production Method

Location 64g of palmitic acid in a heating going down channel to make it in a liquified state; place 200mI. Place thionyl chloride right into the flask, warm it to make its vapor go into the response column with ceramic ring packing with the channel, and also react with the palmitic acid trickled from the upper part of the column, and the unreacted thionyl chloride condenses via the branch pipeline on the upper part of the response column Back to the flask; after palmitic acid was added dropwise, responded for 30min, removed a small amount of thionyl chloride by atmospheric purification, and also gathered 58.6 g of colorless and also transparent liquid at 150 ~ 152 ° C(2 ~ 3kPa) by purification under minimized stress, with a yield of 86% (as palmitic acid).
Add 26.5 mL to the flask. Dimethylformamide, 2 g of HCl gas was travelled through at 0 ° C., and after that 9.69 g of crystalline ascorbic acid and also 13.3 mL were included. Dichloromethane, the reaction solution is clear at this time; gradually decline 15.2 mL of palmitoyl chloride at 0 ° C, respond for 18h after the dropwise addition, and afterwards raise the temperature to 20 ° C for 30min. The catalysts were added to 100 mL. ethyl acetate and also 200mL. Mix as well as clean in water for 2 hours, suction filter, laundry with water (50mL × 3) three times, as well as vacuum-dry at 50 ° C for 18 hours to obtain 17.5 g of white powder with a return of 84.3%.

Ascorbyl Palmitate Ecological Information

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.
