Sodium Hyaluronate Crosspolymer-6 ●
TL;DR. This ingredient is a long-lasting humectant and film-forming skin-conditioning agent. In formulas, it creates a hydrated surface network that improves slip, cushion, and water retention.
What does Sodium Hyaluronate Crosspolymer-6 do in a cosmetic formula?
This ingredient is a long-lasting humectant and film-forming skin-conditioning agent. In formulas, it creates a hydrated surface network that improves slip, cushion, and water retention.
Is Sodium Hyaluronate Crosspolymer-6 clean?
It is generally well tolerated and not a common allergen or sensitizer in finished products. Clean-standard friction comes mainly from the chemical crosslinking step and the need to control residual processing agents.
Is Sodium Hyaluronate Crosspolymer-6 sustainable?
This material is usually built from a fermentation-derived biopolymer, so its starting point can be renewable. Crosslinking may slow biodegradation compared with the linear parent polymer, but it is not typically treated like a persistent silicone or plastic microbead.
Is Sodium Hyaluronate Crosspolymer-6 COSMOS-approved?
It is not automatically aligned with COSMOS-organic or COSMOS-natural because acceptance depends on the crosslinking chemistry, residuals, and supplier documentation. From a Green Chemistry view, the renewable fermentation base is favorable, while added chemical modification makes the profile more qualified than the unmodified material.
How does Sodium Hyaluronate Crosspolymer-6 work chemically?
It is a high-molecular-weight, crosslinked anionic polysaccharide salt that swells in water and forms an elastic hydrated network on the skin. Typical use is low, often around 0.01% to 0.5%, and performance can be reduced by high electrolyte loads, strong acids or bases, or systems that disrupt polymer hydration.
