SODIUM ALGINATE SULFATE

Description

Sodium Alginate Sulfate is a versatile and innovative ingredient derived from brown seaweed. This water-soluble polymer is a modified form of sodium alginate, enhanced with sulfate groups to improve its functional properties. Its unique chemical structure allows it to form stable gels and act as an effective thickening agent in various skincare formulations.

The sulfate modification imparts enhanced moisture-retention capabilities, making it particularly beneficial for hydrating and plumping the skin. Sodium Alginate Sulfate also exhibits film-forming properties, creating a protective barrier on the skin's surface that helps reduce transepidermal water loss. This barrier function can aid in soothing irritated skin and protecting against environmental stressors.

In skincare products, Sodium Alginate Sulfate is utilized for its ability to improve texture, enhance spreadability, and provide a smooth, non-greasy feel. It's compatible with a wide range of active ingredients and can help stabilize emulsions. The ingredient's natural origin and low potential for irritation make it suitable for sensitive skin formulations. Additionally, its gel-forming properties make it valuable in mask formulations and other leave-on treatments designed to deliver prolonged hydration and nourishment to the skin.
