Received from the VA audiologist this morning.
"Our office was alerted that Phonak iCom neckloop may leak an oily substance. Phonak conducted an investigation by an independent lab. The lab confirmed that the oily substance is of no toxicological concern. Phonak recommends that if the skin comes into contact with the oily substance the skin should be washed with soap and water.
The lab identified fatty acids and fatty acid esters. Fatty acids are natural products found in plants and animals and are often used in the processing of polymers. The major ingredient was palmitic acid, which is listed by the FDA as a food additive permitted for direct addition to food for human consumption. Fatty acids are generally considered safe with a low toxicological potential. At high concentrations, fatty acids may cause skin irritation. Fatty acid esters are often used in cosmetics and skin care products. As with fatty acids, fatty acid esters are generally considered safe and can produce skin irritation at high concentrations. Metals analysis identified calcium, potassium, magnesium, and sodium were elevated but only slightly. The only metals detected at higher levels were copper and zinc. These metals are considered to have low to minimal safety concern.
Defective neckloops should be returned to Phonak for replacement. Skin irritation or other health problems related to leaky neckloops should be documented and reported to your patient safety office. Phonak confirmed that all new produced neckloop cables, stocks and shipments since June 2011 will not have any leaking issues."
