実験手順
It can be seen that bleaching from these peroxycarbonic acid bleaches is excellent, giving substantial stain removal on a variety of stains. As evidenced from Table, the SPCC system has been studied most extensively. A number of observations may be gleaned from the Table with respect to SPCC. At a theoretical percarbonic acid yield of 15 ppm active oxygen (9.4×10-4M), outstanding bleaching is obtained at 40° in 15 minutes on hydrophilic stains such as tea, red wine and blackberry. Bleaching remains outstanding at hydrogen peroxide/precursor ratios as low at 2:1. Even at 1:1, bleaching is very good compared to state-of-the-art systems such as sodium nonanoyloxybenzene sulfonate with perborate. At a theoretical percarbonic acid yield of 5 ppm active oxygen (3.1×10-4M), bleaching of hydrophilic stains is comparable to that obtained with sodium nonanoyloxybenzene sulfonate with perborate at 10 ppm active oxygen theoretical peracid. Levels of 15 ppm active oxygen give very good bleaching at 20° C. and perceivable bleaching even as low as 10° C.
