About

Trideceth-3 Phosphate is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Trideceth-3 Phosphate is the phosphate ester of Trideceth-3 (tridecyl alcohol ethoxylated with approximately 3 moles of ethylene oxide). The phosphate moiety reduces the HLB and provides mildness without sacrificing emulsification capacity. EU Regulation (EC) 1223/2009 does not specifically restrict this ingredient. The generic CAS assignments (9046-01-9 / 73070-47-0) reflect variation in the exact alkyl chain distribution and phosphorylation patterns. Phosphate esters of this type are widely used in rinse-off cosmetics.

Skin benefits

  • Mild yet effective cleansing surfactant
  • Provides stable emulsification in various formulations

Known concerns

  • Generic CAS covering multiple isomers may affect regulatory characterization
  • Potential eye irritation in sensitive individuals
