Polyglutamic Acid

Other names: Polyglutamic acid, PGA

Harm score: 2 (Derivatives of natural substances)

Polyglutamic acid, also known as PGA, is a biodegradable polymer produced by bacteria. This substance is synthesized from the amino acid L-glutamate and has a high water-binding capacity. Due to this property, it is increasingly used in the cosmetics industry, where it is becoming a popular ingredient in moisturising and anti-ageing products. The unique structure of PGA allows moisture to penetrate deep into the skin and retain it there for a long time.

In addition, polyglutamic acid is also used in food and agriculture. When added to certain foods, it helps to induce cravings and increase their nutritional value. It is also used as a biodegradable plastic for agricultural purposes. Here it helps to reduce water and nutrient loss from the soil. Due to its high glutamic acid content, it is also used in the medical industry where it works as a pain reliever. Polyglutamic acid is also a key element in the production of some vaccines and biosensors.
