Ozonit is a blend of  Peracetic acid and Hydrogen peroxide made by Ecolab, Inc ..  $^{5}$The "Stain Removal,%" was calculated using the following formula: SR= ((Lfinal - Lintial)/(96 - Lintial)) x 100%  CO: Cotton;  PES/CO: Polyester-Cotton blend  As can be seen from this table, Formula A averages supe› rior bleaching to Ozonitfi. Although the superiority on these  "bleachable" stains is only 3.7 points (5.4%), on those stains  which better resist wash removal e.g. tea, the difference was  as many as 17 points (24%) higher.  Another full scale wash testing was conducted using a  wash wheel (full size side loading washing machine), but  rather than individual soiled swatches this test utilized mul› tipaneled sheets combining 14 "bleachable" stained swatches  (Ecomon 4)  and a second sheet which combined 12  "unbleachable"  pigment/hydrocarbon  stained  swatches  (Ecomon 1 ). These panels are custom made for Ecolab by wfk  Testgewebe Gmbh of Bruggen, Germany. This extensive  bleach test utilized a design experiment which varied concen› trations sometimes simultaneously with temperatures etc.  Following completion of the specified wash time, all Ecomon  In this test, Formula A was compared to Ozonitfi, Ozonit  Superfi (a 15% peroxyacetic acid product available from  Ecolab) and Oxysanfi these were variously combined with  the following commercially available alkaline-builder clean› ing agents: Triplex Emulsionfi, available from Ecolab Inc.;  Turbo Usonafi, available from Ecolab Inc.; Ozonit Superfi,  available from Ecolab Inc.; and Oxysanfi, available from  Ecolab Inc. The results are shown in the tables below.  sheets were rinsed thoroughly, dried and their broad spectrum  light reflectivities were measured, again with UV filtering to  removal possible interference from optical brightener effects.  Unlike the tergotometer data, the % stain removal wasn’t  calculated but was rather directly measured from the reflec› tance instrument (Minolta CM-261 0d Spektrophotometer). A  "Y" value representing broad spectrum reflectivity was  reported. The higher the "Y" value, the whiter the material,  and therefore, the greater the bleaching or stain removal.
