Propylene Glycol Alginate

Product Description

Propylene Glycol Alginate (PGA) is a polysaccharide derivative widely used in modern cosmetic and personal care formulations. It forms a lightweight protective film on the skin, helps retain moisture, reduces transepidermal water loss (TEWL), and improves product texture and stability. PGA delivers deep hydration, long-lasting moisturization, and soothing effects, making it ideal for creams, lotions, gels, serums, and advanced skin care systems.

This multifunctional ingredient is particularly valuable in formulations targeting dry, sensitive, or environmentally stressed skin, as well as products designed for long-lasting hydration and skin barrier support. Propylene Glycol Alginate not only delivers deep hydration but also reinforces the skin barrier, helps alleviate dryness, and soothes sensitive skin, promoting comfort and a healthier-looking complexion.
