Expert Verdict

Similar safety profile to other cyclic silicones. Unlike D4/D5 cyclomethicones, phenyl-modified silicones face fewer environmental persistence concerns, but environmental assessment data for this specific variant are limited. A phenyl-substituted cyclic silicone (methicone series). The phenyl groups increase refractive index and provide enhanced shine and gloss compared to standard dimethicone-based silicones. Higher compatibility with organic oils than non-phenyl variants
