It's noted to have a very low hazard for humans, but silicones' effect on the environment has yet to be determined. Sometimes your products really can feel too good to be true. Thanks to the silicones adhesives we can bond differents materials that require a high temperature resistance and high resistance to microbiological agents. Sulfates, phthalates, and parabens have all been put on the naughty list. Due to their low surface tension silicones are not paintable, showing a behavior similar to hydrophobic materials (water repellent). For example, silicones are part of the glaze of vast expanses of glass that are a feature of many modern architecture buildings. Silicones … No matter what your skin type, one of the ingredients I recommend avoiding is silicone. Silicones … These silicones require energy input in the form of heat in order to activate and produce the curing, unlike the moisture-curing silicones which are formed by polycondensation, these silicones cured by polyaddition process not emitting any kind of volatile compound to the environment. Silicones are also far less readily attacked by electromagnetic and particle radiation (UV, alpha, beta and gamma rays) than organic plastics. Silicones are considered as hybrid adhesives, due that the polymer backbone is inorganic and also has an organic secondary structure, that is why their mechanical and chemical properties are halfway between inorganic and organic adhesives, resulting an elastomeric material with a high temperature resistance and high elongation capacity (elasticity). These are silicones that you cannot remove or penetrate with water, which can inadvertently damage the hair. Silicon is a semi metal belonging to 14th group and 3rd period of the periodic table and it is used most commonly and widely in electronics. Studies have also tried to link parabens to cancer, since they can weakly mimic estrogen, but all results have been inconclusive so far.
