About
A highly branched chelating dendrimer polymer that binds metal ions to improve formulation stability, also functioning as a cleansing and surfactant ingredient.
Sodium Trimethylolpropane Hydroxypropyl Iminodiacetate Dendrimer is the sodium salt of a multi-branched polymer formed by sequential reaction of trimethylolpropane with hydroxypropyl iminodiacetic acid, creating a dendritic architecture with multiple chelating iminodiacetate groups at the periphery. The restriction field referencing 'ban substances that deplete the ozone layer' appears to be a compliance flag, likely related to the ethoxy-carbon chain or processing chemicals; the ingredient itself is not classified as an ozone-depleting substance. Under EU Regulation 1223/2009, this dendrimer is not listed in Annex II or III. As a polymeric chelating agent, it binds divalent and trivalent metal ions in formulations to prevent oxidative rancidity and product instability.
Function
Skin benefits
- Chelating properties help preserve cosmetic formulations by binding metal ion catalysts
- Surfactant cleansing properties contribute to product foaming and soil removal
Known concerns
- Compliance restriction flag referencing historic ozone-layer regulations (non-toxicological flag)
- The iminodiacetate groups may cause mild irritation at high concentrations
