Frequently Asked Questions

1. Q: What does the range 1500-2000 KDa indicate about this Sodium Hyaluronate?

A: The range indicates that the product is a blend or a specific grade where the molecules have an average molecular weight between 1.5 and 2 million Daltons. This categorizes it firmly within the High Molecular Weight (HMW) segment, offering a balance of properties between ultra-high and medium weights.

2. Q: How is 1500-2000 KDa Sodium Hyaluronate typically sourced and manufactured?
A: This specific MW grade is produced through controlled bacterial fermentation and subsequent proprietary purification and fractionation processes. These steps are carefully managed to isolate and preserve hyaluronate chains within this targeted molecular weight range.

3. Q: What is a key formulation challenge addressed by 1500-2000 KDa Sodium Hyaluronate?
A: It addresses the need for significant viscosity and elastic film formation without the extreme thickening behavior of ultra-high MW versions (like 6000 KDa). This makes it easier to formulate with at effective concentrations while still achieving a luxurious, smooth texture.

4. Q: Why would a formulator choose a range instead of a single molecular weight?
A: A range like 1500-2000 KDa provides a consistent and reproducible sensory profile in the final product. A single, precise MW is difficult to produce at scale. A controlled range ensures batch-to-batch consistency in terms of feel, spreadability, and performance.

5. Q: Beyond skincare, where is 1500-2000 KDa Sodium Hyaluronate commonly applied?
A: Due to its excellent lubricity and biocompatibility, this MW range is frequently utilized in ophthalmologic solutions like lubricating eye drops, as well as in some nutraceutical and biomedical applications for its unique physical properties.
