I happened to find this string on a search and have to say there is a great deal of incorrect information about silicone in this string of messages. First silicone is made by hundreds of companies with hundreds of formulas and blends of silicones together to make the final product. The number one type of silicone ingredient in lubes is dimethicone that is a type that is thick soft and smooth. Depending on the what the goal of the lube is will add other silicones to make it last longer, more slick, glide or slide. Silicone can be made in a very pure environmental friendly process or the opposite with a silicone designed for industrial, food preparation, cosmetics or medical. Silicones are inert - BUT MOST SILICONE LUBES CONTAIN OTHER PRODUCTS SUCH AS ALOE, VITAMIN E and the chemicals used to mask color or taste.
Silicone is NOT an oil. It is an inert chemical that will evaporate with time (Water is a chemical also) good quality silicone lubes will not leave a stain. Others that have additives, warmers, flavors will leave a stain and therefore are not hypoallergenic. Silicone Lubes are not sterile or if they are as soon as it is opened it becomes a mute issue. KY Jelly was for a long time the only medical use lube available trusted by Doctors around the world. Silicone lube that claims to be medical grade are just that the grade of silicone and how it is developed - not that it is superior to the others if the purpose is for a lube. Medical grade silicone was designed to stay inside the body for years held within a designated barrier. Cosmetic Grade has been used for years and is more in tune with skin and skin allergies.
Condom testing is not conducted by any regulatory agency anywhere in the world. There is no ISO9000 or equivalent - just random methods that have no procedure or true test process. A company claiming to be condom safe is a broad claim and would be hard to test every condom manufacturer and every change in their manufacturing process. Silicone lubes if they state on their label most likely have tested their product with certain latex condoms and many are fine. But again it is all the other ingredients inside the bottle with the lube that might react and might break down latex.
Regarding toys and the effect silicone has on them is a case by case. It is inaccurate to make a broad claim on silicone without all the facts. Including other items the toy may have come into contact in use, if it was cleaned properly,stored correctly. Read: link
. Some silicones, some waterbased, some oils will have adverse reactions with toys and just because it is labeled one type you should always read the ingredients. Waterbased Flavored with warming agents is not safe to use on toys as it will have some reaction being reactive and reacting as soon as it is dispensed.
Pure silicone will not have a reaction with other pure silicone. It is always wise to test your lube with any toy and never assume just because it has a certain type of lube it is safe to use with your method or other items. Hope this helps.
