Polyglutamate: Unleashing the Versatility of a Biopolymer for Cosmetic Industry Applications

Polyglutamic acid (PGA) is a biopolymer with significant potential in the cosmetic industry due to its biocompatibility, water solubility, and film-forming properties. Microbial production processes for PGA are sustainable and efficient, making it suitable for large-scale synthesis. PGA is beneficial in skincare and haircare products, offering deep hydration, depigmenting properties, and protection in sunscreens. Its ability to improve skin and hair health makes it a valuable ingredient in moisturizers, conditioners, and hydrating masks, aligning with the growing demand for sustainable, bio-derived cosmetic ingredients.
