For years, consumers have complained of underarm garment discoloration caused by the use of deodorant and antiperspirant/deodorant products. The purpose of this investigation was to examine the colorfastness of a 100% cotton and a 50%-50% cotton/ polyester blend fabric after exposure to a deodorant, antiperspirant/deodorant, and perspiration, during actual wear by 60 human subjects. Thirty shields from each test fabric were exposed to two different exposure periods: 1) 1-1/2 days and 2) 5 days before laundering. The analysis of variance revealed that the effect of experimental treatments (ingredients) on the colorfastness of test fabrics was significant (p< 0.002). The Student Newman Keuls statistics revealed that antiperspirant/deodorant caused a greater degree of fabric discoloration than the perspiration alone. Mean scores for deodorant and perspiration revealed that the deodorant treatment also caused a greater degree of fabric discoloration than perspiration alone.
