Let's have a little santity check here, ok? Is a company 'covering up' a scientific FACT that Silicone is extremely stable?? That would be like trying to cover up the temperature that water turns into ice.
Don't take my word for this, do some fact finding for yourself....
There is widespread use of silicone materials and it is difficult to avoid exposure to them (see Table 1). Silicone is incorporated into medicines; used in food processing (for example, canning and ready meals); used in a wide range of medical devices; used as putty and sealants. The use of silicone oils in food processing and food contact can give rise to systemic exposure to small chain silicone components which are known to be absorbed through the gastrointestinal tract. Silicone is used in domestic and personal products such as cleaning solvents, handcream, hair and skin products, and antiperspirants. It may be absorbed orally or through the skin and absorption can be measured on a scale from 'minimal' to 'well'. Silicone is also incorporated in some medicines and medical devices. For example, silicone oil is commonly used as a lubricant in syringes and blood giving sets. People with insulin dependent diabetes are exposed to small but regular doses of silicone oil, resulting in a large, cumulative exposure to silicone over a period of time. Silicones are also used during surgery to repair retinal detachment.
