Polyisoprene condoms were approved in 2008 and are made from a new latex formula that can be used by those with latex allergies. They are a synthetic latex that does not contain the natural proteins which are the source of latex allergies. It is also a thinner form of latex than traditional latex condoms but thicker than polyurethane condoms. They are more expensive than traditional latex condoms, but less expensive than polyurethane condoms. They are more form fitting and stretchy than polyurethane condoms. Like traditional latex condoms, polyisoprene condoms can not be used with oil based lubricants. Unfortunately, like polyurethane condoms they are not biodegradable.
Natural membrane, lambskin or sheepskin condoms are made from the intestinal lining of sheep or lambs. This is the oldest type of condom still being used today. The natural membrane is somewhat porous and is therefore not recommended for protection against certain STDs. This type does, however, protect against pregnancy and bacterial STIs. Some users find these condoms to be more comfortable than those made of latex. They have a strong odor that some find a bit overwhelming compared to latex or polyurethane and are the most expensive of condoms currently available. These are biodegradable condoms which makes them an environmentally conscientious choice.
Silicone Coated Condoms
Many people are under the impression that a silicone coated condom is one that has a solid silicone layer over latex, polyurethane or polyisoprene. This is an incorrect assumption. A silicone coated condom is nothing more than a prelubricated condom that is made out or latex or polyurethane and has silicone lubricant used to lubricate it.
There is only one silicone condom and it is still being reviewed for approval by the FDA. It is to be released in 2014 and appears as though it is going to revolutionize the entire condom industry with the unique designs that it comes in. The ability to recycle is yet to be determined, as is the ability to reuse it. To learn more about these condoms see Origami Condoms.
& Spermicides In Condoms
One thing to explore is the lubricants that your condoms come prelubricated with as some can contain toxins. Examples of controversial toxins are parabens. See more regarding this topic through our helpful article on lubricants.
No Recycling for Condoms Outer Wrapping
The plastic and foil wrappers that latex condoms are packaged in are also not biodegradable and this should be taken into consideration as well. It would be excellent if consumers were able to pressure condom companies into making more ecofriendly wrapping for their products.
