About
A dialkyl maleate ester functioning as a plasticising and film-forming ingredient in specialised cosmetic formulations, with limited but generally acceptable safety data for cosmetic use.
Bis-(1-Methylheptyl) Maleate (also known as diisoheptyl maleate) is the diester of maleic acid and 1-methylheptanol (isoheptanol). Maleate esters are used in cosmetic formulations as plasticisers, film-forming agents, and opacifying agents. Maleic acid itself is not classified as a sensitiser, though high concentrations of ester monomers may cause irritation. No specific EU restrictions apply to this specific compound under Regulation 1223/2009, though it is not a common cosmetic ingredient and specific usage data are limited. A product-specific safety assessment is recommended.
Known concerns
- Maleate ester - potential for skin irritation at high concentrations
- Limited cosmetic usage data
- May act as a plasticiser or film-forming component
