Expert Verdict

Silicone polymer essentially inert on skin; verify molecular weight specification as lower MW fractions can have increased penetration; no genotoxicity or reproductive toxicity concerns per CIR; environmental persistence of silicones under ongoing regulatory scrutiny but D4/D5 cyclomethicone restrictions do not apply to linear dimethicones.
