About

29h,31h-phthalocyanine is a cosmetic ingredient. Exercise caution due to limited available safety data.

29H,31H-Phthalocyanine (CAS 574-93-6) is a metal-free phthalocyanine that functions as a blue colorant in cosmetic formulations. EU Regulation 1223/2009 Annex III restricts its use to rinse-off products only. The compound is structurally related to copper phthalocyanine but without the metal center. At permitted concentrations it shows minimal toxicity and is considered safe for use in decorative cosmetics including makeup and hair care products. The restriction to rinse-off products limits potential for eye contact and prolonged skin exposure.

Skin benefits

  • Used in rinse-off makeup and hair care formulations
  • Alternative to copper phthalocyanine in sensitive applications

Known concerns

  • Restricted to rinse-off products only in EU
  • Prohibited above 0.1% in mixtures
