Sodium Hyaluronate

Sodium Hyaluronate

Also Known As: Hyaluronate Sodium, Sodium Salt of Hyaluronic Acid

What is it?

Sodium Hyaluronate is the sodium salt form of Hyaluronic Acid (HA), a naturally occurring glycosaminoglycan found in various connective tissues of humans. It is known for its remarkable ability to retain moisture, making it a popular ingredient in skincare and medical products.

What Makes it Different?

The primary difference between Sodium Hyaluronate and Hyaluronic Acid lies in their molecular weight. Sodium Hyaluronate has a lower molecular weight, allowing it to penetrate the skin more deeply compared to Hyaluronic Acid, which tends to stay on the surface. This deeper penetration enhances its hydrating and plumping effects on the skin.

Where Does it Come From?

Sodium Hyaluronate is derived from Hyaluronic Acid, which can be sourced from animal tissues or produced via bacterial fermentation. The latter method is more common in modern production due to ethical and sustainability considerations.

Where is it Used?

Sodium Hyaluronate is widely used in:

• Skincare Products: Moisturizers, serums, and eye creams to enhance skin hydration and reduce the appearance of fine lines and wrinkles.
• Medical Applications: Intra-articular injections for osteoarthritis, eye drops for dry eyes, and as a surgical aid in ophthalmic procedures.

Is it Sustainable?

The sustainability of Sodium Hyaluronate largely depends on its production method. Bacterial fermentation is considered more sustainable and ethical compared to extraction from animal tissues. This method reduces the environmental impact and aligns with vegan and cruelty-free standards.

Sustainable Issues Related to its Production

While bacterial fermentation is more sustainable, it still involves the use of resources such as water, energy, and raw materials. The production process must be carefully managed to minimize environmental impact. Additionally, the disposal of by-products and the use of genetically modified organisms (GMOs) in fermentation can raise sustainability concerns.
