SODIUM POLYGAMMA-GLUTAMATE CROSSPOLYMER

Description

Sodium Polygamma-Glutamate Crosspolymer is an innovative skincare ingredient that has gained attention for its exceptional moisturizing and hydrating properties. This synthetic polymer is derived from fermented soybeans and is structurally similar to the natural moisturizing factors found in human skin. Its unique cross-linked structure allows it to form a protective film on the skin's surface, effectively reducing transepidermal water loss and enhancing skin hydration.

The ingredient demonstrates remarkable water-binding capabilities, able to hold up to 5000 times its weight in water. This property makes it particularly effective in formulations designed for dry or dehydrated skin. Sodium Polygamma-Glutamate Crosspolymer also exhibits film-forming abilities, which can help smooth the appearance of fine lines and wrinkles, giving the skin a plumper, more youthful appearance.

In addition to its hydrating benefits, this polymer has been shown to enhance the delivery of other active ingredients in skincare formulations. It is non-irritating and suitable for sensitive skin types. The ingredient is typically used in concentrations ranging from 0.1% to 3% in various skincare products, including serums, moisturizers, and masks, where intense hydration is desired.
