Sex Toy Silicone, in recent years the use of silicone materials in sex toys has increased both because of cheaper cots associated with silicone, as well as consumer demand for safer sex toys that are Phthalates free, BPA free, and can be sterilized to eliminate any potential bacteria.
Silicone's key advantages are its safe, yet flexible material, where as most materials for adult toys such as vibrators that be be sterilized are from such material as hard plastics, silicone retains a flexible composition, yet is non-porous, and many can be placed in the upper rack of dishwasher for simple care and cleaning.
Other materials made to be lifelike while safe for internal use, such as TPR, or Sil-a-Gel, can not be sterilized and therefor shouldn't be used between multiple partners without a condom to prevent any possible chance of a Sexually Transmitted Disease.
There are however limitations with silicone sex toys. Male Masturbators created from silicone while being safe can only be used with a water-based lubricant as silicone-based lubricants will degrade the material causing it to become sticky and tacky.
Silicone toys are typically higher priced, but consumers who wish to purchase only deluxe sex toys realize the price of silicone material products also ensures safer toys. The higher price is reflective of the cost of the material, where as
those adult novelties that rank lower on the safety rating are priced lower, but is reflective of the materials safety and ability to be sterilized.
Because silicone materials are of higher grade this also ensures a longer product life, so while it may be more expensive to purchase now, it's extended life saves dollars down the road. Many silicone dildos, can expect to have a lifetime worth's of use with proper care and cleaning.
And remember for all types of sex toys, it is best to store in a cool and dry place. Moisture can damage some materials, just as sunlight can fade the color, or degrade the material, silicone or otherwise.
