It is a high-molecular-weight polymer derived from the fermentation of glutamic acid. The molecular weight range of 8-12 kDa refers to the size of the polymer chains.

It is known for its exceptional moisture retention properties, providing long-lasting hydration. It also enhances skin elasticity, reduces the appearance of fine lines, and improves the overall texture of the skin.

Both are excellent moisturizers, Sodium Polyglutamate has superior water retention capabilities and can hold more moisture than Hyaluronic Acid. Additionally, Sodium Polyglutamate provides a smoother feel on the skin and enhances the performance of other active ingredients.

Yes, it is compatible with a wide range of cosmetic ingredients, including other moisturizers, emulsifiers, and active ingredients. However, formulators should always conduct stability tests to ensure compatibility in their specific formulations.

The molecular weight of 8-12 kDa indicates that Sodium Polyglutamate in this range has an optimal balance between viscosity and skin penetration, making it ideal for cosmetic applications that require both hydration and smooth application.

Yes, It is versatile and can be used in both leave-on products, such as creams and serums, and rinse-off products, like shampoos and conditioners.

It is generally well-tolerated by most skin types and is considered non-sensitizing. However, it is advisable to conduct patch tests, especially when formulating for sensitive skin.

It can enhance the sensory feel of products by providing a smooth, silky texture. It can also improve the spreadability and absorption of formulations, leading to a better user experience.

Yes, it is biodegradable and considered environmentally friendly. It breaks down into natural amino acids, making it a sustainable choice for cosmetic formulations.

It should be stored in a cool, dry place, away from direct sunlight and moisture. Proper storage conditions help maintain its stability and effectiveness over time.
