About
A silicone with phenyl groups added — it gives a glossy finish used in shine-enhancing haircare and makeup. Safe on skin; silicones persist in the environment.
Hydrogen Diphenyl Dimethicone (CAS 68037-60-5) is a phenyl-substituted siloxane with Si-H functionality; the phenyl content raises the refractive index giving a glossy, premium sensorial. Used in haircare shine serums and colour cosmetics. Phenyl silicones have been considered safe by CIR in their respective dimethicone and phenyl-dimethicone reviews. Si-H containing silicones may require handling considerations during manufacture. No GHS hazards at finished-product concentrations.
