Differences between DiEticones (PolydiEthylSiloxanes) and DiMetikones (PolydiMethylSiloxanes)
DiEticon Properties
- for many years, DiMetikones have been used in many formulations, but their inability to dissolve in various surfactants, emollients, oils and waxes often causes problems with the formulations;
- DiEticons, have a significant advantage in the ability to solubilize a much wider range of organic compounds such as hydrocarbons, esters, waxes, oils and surfactants;
- DiEticones, known as hybrid silicone polymers, have excellent flow and gas permeability like dimethicones;
- Low surface tension allows DiEticones to spread more easily over hair and skin, acting as a lubricant and anti-stick agent, increasing lubricity. DiEticons act as tackifiers and provide a dry and silky feel with additional cushioning in most formulations, depending on the available molecular weight;
- DiEticons provide more than conventional silicone "glide". They give a softening, non-greasy feeling, a silky dry feeling is softer than traditional DiMetikones of the same viscosity;
- additional advantages of DiEticons when caring for the sun are that they create a hydrophobic barrier (while being washed off), while maintaining vapor permeability, which leads to a more comfortable feeling. DiEticons are inert and chemically stable, non-toxic, non-irritating and non-sensitizing;
- DiEticones have a much broader organic compatibility than Dimethicones with common raw materials used in sunscreens, including hydrocarbons, esters, waxes and sunscreens;
- the wetting properties were assessed by preparing crushed pigments in DiEticon and DiMetikon of equal viscosity. A solvent binder with better moisture will be more effective in displacing adsorbed gases from pigment surfaces. This, in turn, will result in lower viscosity grinding. The finished forms of dispersions of inorganic pigments modified with silane and siloxane with Dieticones have a significantly lower viscosity. In addition, Dieticons moisturize pigments well when formulating color cosmetics.
