What is it?
Ascorbic Acid, also known as Vitamin C, is a naturally occurring organic compound with antioxidant properties found in many foods like citrus fruits, tomatoes, and red peppers. It is an essential nutrient for the human body and also a common dietary supplement.
Historically, it was common knowledge to sailors in the 18th century that lemon and lime juice could help prevent scurvy. By early 1907, two Norwegian physicians investigating dietary-deficiency diseases discovered an essential disease-preventing compound in foods, which eventually came to be called vitamin C.
What does it do?
Ascorbic acid’s primary function in our personal care products is as an antioxidant. While ascorbic acid when taken as a supplement helps prevent cell damage in the human body, the antioxidant properties in the finished product help to protect the product integrity and extend the shelf life of the product. It can also be used as a pH adjuster.
How is it made?
Ascorbic acid can be sourced from citrus fruits or prepared from corn glucose by a method based on the historical “Reichstein process”. The ascorbic acid that we use is derived from citrus fruits.
