volatile silicones are defined

As used herein, volatile silicones are defined, in a known manner, to be compounds which might be volatile at room temperature. Mention might be made, e.g., among these compounds, to cyclic and linear volatile silicones with the dimethylsiloxane type, whose chains comprise from three to 9 silicone-based residues. Cyclomethicones D4, D5 and D6 may, for example, be used. As used herein, non-volatile silicones are defined, in a very known manner, as being compounds which has a low vapour pressure at room temperature, landscape oil paintings such as polyalkylsiloxanes, including linear polyalkylsiloxanes, including linear polydimethylsiloxanes, or dimethicones; polyalkylarylsiloxanes, as an example, polymethylphenylsiloxanes; and copolymers of polyether and siloxane, for example, dimethicone copolyols.

Among the non-volatile emollient oils which may be used, these include hydrocarbon-based derivatives, mineral oils, fatty alcohols, esters of C3-C18 alcohols with C3-C18 acids, esters of benzoic acid with C12-C18 alcohols and mixtures thereof, C2-C6 polyols, by way of example, chosen from glycerol, propanediol or sorbitol, hand-painted oil painting polyalkylene glycol polymers. A single embodiment, the emollient oil is present in a amount starting from 1% to 50 wt. % in the composition. Inside a second embodiment, from 5% to 40 wt. %. Other suitable liquid carriers include organic solvents. Suitable organic solvents employ a melting point of less than 10° C., which benefit both low temperature storage stability and easy manufacture. These include aliphatic alcohols and polyglycol ethers such as dipropylene glycol, glycerol propanediol, butylene glycol, ethanol, propanol, isopropanol, and industrial methylated spirits. Samples of organic solvents include aliphatic alcohols, such as ethanol and isopropanol. A single embodiment, the liquid carriers comprise a minimum of one of the salicylate-based compound, for example glycol salicylate and birch oil, acetone, and menthol, on an icy cold sensation upon application.
