Di-pentyl Isopentyl Terephthalate is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Di-Pentyl/Isopentyl Terephthalate is an aromatic dicarboxylic acid ester of branched pentyl alcohols. It is used as a plasticizer and film-forming agent in cosmetic formulations, providing flexibility and smooth application characteristics. The compound is not listed on any EU prohibition annexes under Regulation 1223/2009. While it is structurally similar to other phthalate esters that have faced regulatory scrutiny, the branched pentyl/isopentyl substituents distinguish it from regulated phthalates, and it is not classified as a CMR substance under EU CLP.

Skin benefits

  • Provides smooth, flexible film on skin
  • Improves texture and spreadability of formulations
  • May increase durability of film-forming cosmetic products

Known concerns

  • Structurally related to phthalate esters under regulatory monitoring
  • Film-forming properties may not be suitable for all skin types
  • Limited long-term toxicology data compared to well-studied cosmetic ingredients
