Formulation of powder ascorbic acid

I would like to know what type of formulation Lamberts powder has ascorbic acid. There are many for sale and since vitamin C oxidizes very quickly in contact with air, I wondered if it chemically has any modification that makes it more durable.

R/ Our ascorbic acid is pure ascorbic acid and has not had any chemical alteration. Although it is prone to oxidation, our packaging is tested with the dose and the shelf life of the nutrient, it is within its specifications.

There are 5 parameters that affect the degradation of ascorbic acid: oxygen, metal ions, pH, light and temperature.

Oxidation of ascorbic acid can be reduced / avoided if no oxidant is present. When left open to air, ascorbic acid is prone to oxidation, but if our containers are kept closed when not in use, the amount of oxygen that enters and oxidizes ascorbic acid will be limited. Although opening and closing several times a day will allow oxygen to enter, the product has been tested to ensure it meets the specifications and the shelf life of 2 years.

It is known that light influences the rate of oxidation of vitamin C. Although the general advice is to keep it in a dark place, our HDPE containers act as an effective barrier against light.

The temperature determines the movement of the molecules, the higher the temperature, the more atoms and molecules will move. This makes it more likely that the molecules will find each other and, therefore, react. Therefore, a higher temperature often results in a higher reaction rate. This is also the case with the oxidation of vitamin C, while our HDPE containers (High Density Polyethylene) provide some protection against temperature, so we also recommend storage in a cool place.
