About
Colloidal palladium is a suspension of palladium nanoparticles in water used in cosmetics for its purported anti-aging and antioxidant properties; however, noble metal nanoparticles require careful safety evaluation regarding skin penetration.
Colloidal Palladium (CAS 7440-05-3) consists of palladium particles suspended in water. Palladium is a noble metal from the platinum group with known low systemic absorption through intact skin. However, nanoparticle forms require additional safety consideration regarding potential skin penetration and local effects. Colloidal metals have a long history of use in alternative medicine and cosmetics, particularly in Asia. Not specifically restricted in EU Regulation 1223/2009 Annex II or III. The SCCS has not issued specific guidance on colloidal palladium; safe use requires careful formulation and nanoparticle characterisation.

- Jewelry-grade metal for luxury cosmetics
Known concerns
- Nanoparticle considerations for skin penetration potential
- Limited SCCS safety guidance specific to colloidal palladium
- Potential for metal ion release in aqueous formulations
- Quality and particle size characterisation important
