What is pga alcohol?

Propylene glycol alginate (PGA) is a polysaccharide derived from brown algae. It is a water-soluble, viscous liquid or gum that is commonly used as a thickening, gelling, and stabilizing agent in food, pharmaceutical, and personal care products. PGA is an FDA-approved food additive and is considered generally safe for consumption.

In personal care formulations, PGA alcohol refers to propylene glycol alcohol, also known as propanediol, which is often used as a solvent, humectant, or viscosity modifier. Propylene glycol alcohol has a slightly sweet taste and can help maintain the skin's moisture, making it commonly found in skin creams, lotions, and cosmetics. However, individuals with sensitive skin or allergies should always check the product label prior to use.
