Soluble Proteoglycan ●
TL;DR. It functions mainly as a humectant and skin-conditioning film former, helping a formula hold water at the skin surface and giving a smoother after-feel.
What does Soluble Proteoglycan do in a cosmetic formula?
It functions mainly as a humectant and skin-conditioning film former, helping a formula hold water at the skin surface and giving a smoother after-feel.
Is Soluble Proteoglycan clean?
Clean frameworks generally view it as a low-use moisturizing and conditioning biopolymer rather than a restricted synthetic. Main watchpoints are animal origin, residual-protein sensitization screening, the preservative system, and supplier documentation.
Is Soluble Proteoglycan sustainable?
This ingredient is usually obtained by extraction from marine or animal connective-tissue byproducts, though supplier-specific biotechnology routes may exist. It should be biodegradable as a biological macromolecule, but sustainability depends on traceable sourcing, byproduct use, water use, and preservation of the extract.
Is Soluble Proteoglycan COSMOS-approved?
It is not a straightforward COSMOS-natural or COSMOS-organic fit unless the supplier documents an allowed natural origin and compliant extraction, and animal-tissue sourcing creates significant eligibility friction. Its Green Chemistry profile is mixed, since water solubility and low use levels help, while traceability, extraction inputs, and end-of-life data are less clear than for simple plant-derived humectants.
How does Soluble Proteoglycan work chemically?
This material is a high-molecular-weight protein-carbohydrate complex with many anionic sulfate and carboxylate groups, which supports water binding and light film formation. It is usually used well below 1% in serums and lotions, added in the cool-down phase, and formulated near skin-compatible pH because strong acid, strong alkali, high heat, or enzyme contamination can degrade it.
