Propylene Glycol Alginate
Propylene Glycol Alginate (PGA) is a highly versatile ingredient derived from natural seaweed. It functions exceptionally well as an emulsifier, stabilizer, and thickener across a wide range of industries, most notably in food, pharmaceuticals, and cosmetics. Its unique chemical structure allows it to maintain stability in acidic conditions, a property that sets it apart from many other alginates, making it invaluable for low-pH food products and certain pharmaceutical formulations. The lipophilic nature imparted by the propylene glycol group also provides surface-active properties, enhancing its performance in oil/water systems.

Key Advantages
Acidic Stability
Propylene Glycol Alginate excels in environments where other alginates might degrade, offering reliable stabilization for acidic food products and formulations. This makes it a preferred choice for items like salad dressings and acid milk beverages.
Enhanced Emulsification
The amphiphilic nature of PGA, due to the propylene glycol group, grants it excellent emulsifying capabilities, allowing oil and water components to blend harmoniously for improved product consistency.
Foam Stabilization
A unique characteristic of Propylene Glycol Alginate is its ability to stabilize foam, making it a valuable additive in products like beer, contributing to a finer, longer-lasting head.
Key Applications
Food Industry
As a food additive, PGA is widely used as a thickener and stabilizer in dairy products, beverages, sauces, and dressings, enhancing texture and shelf life.
Pharmaceuticals
In pharmaceutical preparations, Propylene Glycol Alginate serves as an excellent suspending agent and stabilizer for liquid medications and topical creams, ensuring product uniformity.
Cosmetics
PGA finds application in cosmetic formulations, acting as a stabilizer and thickener in creams, lotions, and serums to improve texture and product feel.
Beverage Stabilization
For beverages, particularly those with low pH or containing calcium, propylene glycol alginate is crucial for preventing precipitation and maintaining a stable, consistent product.
