About

A complex polymer matrix incorporating diamond powder and benzimidazole groups, used for brightening and conditioning effects.

This is a sophisticated composite material combining a diamond powder (nanodiamond or diamond particles) embedded in a polymethylsilsesquioxane silicone matrix with benzimidazole and urea groups. The PubChem safety score of 55 reflects concerns related to the benzimidazole moiety, which may have sensitization potential. It is not listed in EU Annex II (banned substances) under Regulation EC 1223/2009, but its complex structure warrants caution regarding impurity control and skin compatibility testing.

Skin benefits

  • Provides skin-conditioning and film-forming benefits
  • Silicone matrix adds water-resistance and smooth texture

Known concerns

  • Benzimidazole component may pose sensitization risk in susceptible individuals
  • Complex structure requires rigorous purity assessment
  • Diamond particle inhalation risk in powder formulations
