Sodium Polyitaconate ●
TL;DR. This ingredient primarily acts as a chelating and dispersing agent, helping bind trace metal ions that can destabilize formulas or dull performance. It can also support clarity, lather quality, and mineral-management in water-based products.
What does Sodium Polyitaconate do in a cosmetic formula?
This ingredient primarily acts as a chelating and dispersing agent, helping bind trace metal ions that can destabilize formulas or dull performance. It can also support clarity, lather quality, and mineral-management in water-based products.
Is Sodium Polyitaconate clean?
From a clean-beauty perspective, this ingredient is generally low-friction, with low sensitization concern and no common restricted-list issue. The main nuance is that it is a manufactured polymer, so brands usually look for biodegradability data and residual monomer controls.
Is Sodium Polyitaconate sustainable?
This material is commonly made from a fermentation-derived building block, which gives it a stronger renewable-sourcing profile than many conventional chelants. It is water-soluble and readily biodegradable, with low concern for environmental persistence.
Is Sodium Polyitaconate COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when the specific commercial grade meets the standard’s raw-material criteria, and COSMOS-approved grades are available. Its Green Chemistry fit is strong because it can use renewable feedstock, performs at low levels in water-based systems, and has a favorable biodegradation profile.
How does Sodium Polyitaconate work chemically?
The molecule is an anionic sodium polycarboxylate, so repeated carboxylate groups bind metal ions and provide charge-based dispersion in aqueous formulas. It is typically used at low active levels, often around 0.05% to 1% for chelation support, remains water-soluble across common cosmetic pH ranges, and may interact with strongly cationic conditioning systems.
