What materials are compatible with ethylene oxide?
Ethylene oxide penetrates well through porous materials such as medical grade paper and polyolefin non- woven materials and is highly effective as a sterilant for sterile barrier systems which have adequate porosity.
What devices are sterilized with ethylene oxide?
Medical devices made from certain polymers (plastic or resin), metals, or glass, or that have multiple layers of packaging or hard-to-reach places (for example, catheters) are likely to be sterilized with ethylene oxide.
Does ethylene oxide degrade plastic?
Because ethylene oxide (EtO) can sterilize at low temperatures, the main advantage of this gas for hospital sterilization is that it will not damage heat sensitive materials, such as plastics.
Which packaging material is not compatible with hydrogen peroxide sterilization?
Cellulose-containing packaging materials are not compatible with hydrogen peroxide sterilization. Information about a device’s compatibility with a specific sterilization process should be obtained from the device’s manufacturer.
Is ethanol compatible with polypropylene?
Polypropylene copolymers swell more than homopolymers, indicating greater absorption. Such nonpolar liquids as benzene, carbon tetrachloride, and petroleum ether have a higher absorption rate with polypropylene than polar media such as ethanol and acetone.
Where is EtO used?
ETO is used in healthcare facilities to sterilize critical items (and sometimes semicritical items) that are moisture or heat sensitive and cannot be sterilized by steam sterilization.
What else is ethylene oxide used for?
Ethylene oxide is most commonly used in the production of other chemicals including the production of solvents, antifreeze, detergents, adhesives, polyurethane foam and pharmaceuticals.
Can ethylene oxide penetrate glass?
Materials compatibility. Ethylene oxide is compatible with many plastics. Metals and glass do not absorb ethylene oxide and are do not present any problems for sterilization.
How long does ethylene oxide stay on surfaces?
EtO is a volatile compound, meaning that it does not persist for a very long time in the environment. Its estimated half-life in the atmosphere is 69 days (during summer months) to 149 days (during winter months).
What is not compatible with hydrogen peroxide?
Hydrogen Peroxide (anhydrous) Chromium, copper, iron, most metals or their salts, aniline, any flammable liquids, combustible materials, nitromethane, and all other organic material.
Which of the following is compatible with hydrogen peroxide sterilization?
Previous industrial experience has shown that hydrogen peroxide vapor is compatible with, and safe for, a wide range of materials typically used for medical devices, including metals (300 series stainless steel, aluminum, and titanium), plastics (polypropylene, polyethylene, and polycarbonate), and other materials ( …
What is compatibility chart for chemicals?
This Chemical Compatibility Chart is a shorthand tool for describing the suitability of miniature fluidic and pneumatic component materials for use in contact with various chemicals.
What does polypropylene react with?
Polypropylene resins, like most polyolefin resins, are highly resistant to solvents and chemicals. They are appreciably affected by strong inorganic acids such as fuming nitric acid at room temperature and 98% sulfuric acid at 600C.
Is ethylene oxide corrosive to metal?
Ethylene oxide decomposes or polymerizes violently on contact with potassium, tin, zinc, aluminum, iron oxides, copper, silver, mercury, magnesium and their alloys. It will also react violently with caustic soda, hydrated lime, magnesium chloride, ammonia, alcohols and amines.
How long does EtO sterilization last?
The basic ETO sterilization cycle consists of five stages (i.e., preconditioning and humidification, gas introduction, exposure, evacuation, and air washes) and takes approximately 2 1/2 hrs excluding aeration time.
