PRINCETON, N.J. — In an unconventional move for a maker of consumer healthcare products, Church & Dwight’s Trojan condom brand will be a first-time exhibitor at the 2011 International Consumer Electronic Show. The company plans to use the highly publicized event to unveil a host of new products, including a multitip personal massager and “the new thinnest latex condom in brand history,” according to the company.
