Sodium Hyaluronate. May Contain: Red 28

TL;DR. This ingredient is primarily a humectant and skin-conditioning film former, helping bind water at the skin surface and improve slip in serums, creams, masks, and eye products.

What does Sodium Hyaluronate. May Contain: Red 28 do in a cosmetic formula?

This ingredient is primarily a humectant and skin-conditioning film former, helping bind water at the skin surface and improve slip in serums, creams, masks, and eye products.

Is Sodium Hyaluronate. May Contain: Red 28 clean?

The base material is generally well tolerated, with low irritation and sensitization potential. A grade that may contain the listed synthetic colorant has more clean-standard friction, since some programs restrict or scrutinize added synthetic dyes.

Is Sodium Hyaluronate. May Contain: Red 28 sustainable?

This material is commonly made by microbial fermentation from sugar-based feedstocks, with older animal-derived routes now less common in cosmetics. It is biodegradable and not known for environmental persistence, while the added synthetic colorant is less aligned with natural-origin sourcing.

Is Sodium Hyaluronate. May Contain: Red 28 COSMOS-approved?

This ingredient can be permitted in COSMOS-natural and COSMOS-organic formulas when made by approved fermentation and purification routes. Its Green Chemistry profile is strongest when fermentation-based and minimally colored, while a grade carrying a synthetic colorant can complicate certification alignment.

How does Sodium Hyaluronate. May Contain: Red 28 work chemically?

It is an anionic polysaccharide salt built from repeating sugar-acid and amino-sugar units, and different molecular-weight grades change feel, film formation, and surface hydration. Typical use levels are about 0.01% to 2%, often 0.1% to 0.5%, with best stability in mildly acidic to neutral formulas and reduced performance under strong oxidation or extreme pH.
