Dimethicone

A silicone emollient that forms a silky protective film and suppresses moisture evaporation.

Polydimethylsiloxane forms a breathable film on the stratum corneum surface, suppressing TEWL while giving a smooth feel.

Loading-dependent (from a few percent).

Feel and protective effect immediately after application.

Few significant cautions.
