Sodium Ascorbate is a kind of white to
yellowish white crystalline powder or granules, odorless, slightly salty
flavor. The decomposition temperature of it is of 218 ℃, in the dry conditions are more
stable, light color burn, after moisture absorption and slow oxidation and
decomposition in aqueous solution. Sodium Ascorbate can be much easier to be
soluble in water than Ascorbic Acid, 10 % aqueous solution PH is about 7.5.
First aid measures:
Ingestion: Do not induce vomiting. If the
victim is conscious, instead of convulsions, give 1 or 2 glasses of water to
dilute the chemicals, and to make a hospital or poison control center
immediately.
Breath in: Leave the contaminated area
immediately and take deep breath of fresh air. If the symptoms (such as
wheezing, coughing, shortness of breath, or in the mouth, throat, or chest
burning), call the doctor, and was prepared to transport victims to hospitals.
Skin: It can cause skin irritation.
Symptoms may include redness and burning of the skin and other skin damage.
Gently and thoroughly wash all affected skin areas with soap and water. If you
develop symptoms such as redness or irritation, immediately call a doctor, and
be prepared to transport the victim to a hospital for treatment.
Eyes: First check the victim of contact
lenses, if present removed. While calling a hospital or poison control center
for 20 to 30 minutes of water or saline solution flush eyes of the victims. Do
not put any ointments, oils, or medication in the victim 's eyes, the doctor
did not specify. If symptoms ( such as redness or irritation ) development,
please transported the victim to a hospital immediately.
The stability of Sodium Ascorbate:
Aqueous solution is unstable, and the air
is greater than pH 6.0 by the relative stability when exposed to rapid
oxidation of Ascorbic Acid gradually darken light it is exposed to light in the
air is gradually dimmed, but not damage, slight coloration therapeutic activity
Ascorbic acid injection. Solution of Ascorbic Acid is rapidly oxidized in the
air, the drug in an alkaline medium should be protected, air and light.
Ascorbic Acid at concentrations greater than 100 mg/ml may undergo
decomposition and the production of carbon dioxide. Due to the increased
pressure may develop after prolonged storage, carefully open the ampoule
containing Ascorbic Acid injection.
