Frequently Asked Questions

1. Q: Is 1200 KDa Sodium Hyaluronate considered high or low molecular weight?
A: A molecular weight of 1200 KDa (1.2 Million Daltons) is classified as High Molecular Weight Sodium Hyaluronate. This is a key distinguishing factor from lower weight variants like 10,000 Da or 200 kDa.

2. Q: What are the key physical characteristics of 1200 KDa Sodium Hyaluronate?
A: The primary characteristic of 1200 KDa Sodium Hyaluronate is its ability to form highly viscous solutions and elastic films at relatively low concentrations. It has strong water-binding capacity and contributes significantly to the texture of a formulation.

3. Q: Why is 1200 KDa Sodium Hyaluronate used in serums and lotions?
A: In formulations, it is primarily used as a viscosity enhancer and film-forming agent. It helps create the desired, often luxurious, texture and feel of a product, improving its application and stability on the skin.

4. Q: How is 1200 KDa Sodium Hyaluronate processed for use in products?
A: This ingredient is typically supplied as a white or off-white free-flowing powder. It requires dispersion and hydration in water to form a clear gel, which is then incorporated into the final product formulation.

5. Q: Can 1200 KDa Sodium Hyaluronate be used with other molecular weights?
A: Yes, it is very common to blend 1200 KDa High Molecular Weight Sodium Hyaluronate with mid-range and low molecular weight versions (e.g., 200 kDa, 50 kDa). This combination is used to achieve specific textural and performance profiles in a final product that a single weight cannot provide alone.
