Expert Verdict

Crosslinked silicone elastomer creating soft-focus optical matte finish in lip products by absorbing surface oils and scattering light. Provides velvet texture without the full drying effect of alternative matte systems. CIR confirms safety with no allergenicity concerns. Biologically inert with negligible absorption; oral ingestion from lip products is safe as crosslinked silicone passes through GI tract without systemic absorption. No regulatory restrictions.
