NEW YORK — ILEX Consumer Products Group last year launched amid the chaos of Black Friday its “Di-Gel Comfort Zone” — complementary, clean restrooms located in downtown Manhattan to help alleviate some of the discomfort associated with shopping the day after Thanksgiving. In the past year, the antacid, anti-gas combo has rocketed to the No. 5 spot of antacid liquid sales, generating $2.2 million on growth of 19,904.6%.
