Volatile silicone with light spreadability. Gives a 'silk' slip on skin and evaporates quickly without leaving residue.
Topical application
CWeak evidence. In vitro data, open-label studies, or expert consensus.
Functional volatile silicone. No standalone clinical effect; excellent tolerance.
Methyl Trimethicone is a volatile silicone, a branched analog of cyclomethicone. After application, it evaporates in 10–30 minutes, leaving a thin film. Mechanism. Spreads on skin and hair to form a smooth, dry surface. Leaves no stickiness or weight. Reduces friction in makeup and hair products. Compared with cyclopentasiloxane (D5) – a different volatility profile and no EU regulatory restrictions. Where applied. Primers, foundations, BB creams, hair heat-protection products, dry hair sprays, antiperspirants. Concentration 1–30%. Evidence base. No clinical RCTs needed – a functional filler, an aesthetic modifier. CIR confirmed safety. Safety. Hypoallergenic, non-comedogenic. Pregnancy and lactation – topically safe. Does not accumulate in the body. Volatile silicone controversy. The EU has restricted cyclomethicones D4, D5, D6 in leave-on products since 2020 due to environmental persistence. Methyl trimethicone is not on that list – it is positioned as a safer alternative for the volatile effect in formulas.
