SODIUM POLYGLUTAMATE

Description

Sodium Polyglutamate is a potent humectant and moisturizing agent derived from fermented soybeans. This water-soluble ingredient is known for its exceptional ability to attract and retain moisture, making it a valuable addition to skincare formulations. With a molecular weight lower than hyaluronic acid, Sodium Polyglutamate can penetrate deeper into the skin, providing hydration to multiple layers.

This ingredient boasts impressive water-holding capacity, capable of retaining up to 5,000 times its weight in water. This property helps to maintain skin hydration, reduce transepidermal water loss, and improve overall skin texture. Sodium Polyglutamate also exhibits film-forming properties, creating a protective barrier on the skin's surface that locks in moisture and shields against environmental stressors.

In addition to its hydrating benefits, Sodium Polyglutamate has been shown to enhance the production of Natural Moisturizing Factors (NMFs) in the skin, further supporting the skin's natural moisture balance. It is well-tolerated by most skin types and can be particularly beneficial for dry, dehydrated, or mature skin. Its compatibility with various other skincare ingredients makes it a versatile component in moisturizers, serums, and hydrating masks.
