Coral slabs were bleached in 6% reagent grade NaClO for 24 hours to remove organic material and rinsed three times in an ultrasonic bath filled with DI water. Powder samples were milled along four paths for geochemical analysis (Fig.1). The main difference between sampled paths is that path...
13.The dual-agent mixing set of claim 1, said mixing set comprising: (a) a dual-agent bowl containing a polishing agent dominated by pelelith powder with high pH accelerators pre-installed, (b) a syringe containing a bleaching agent dominated by hydrogen peroxide with low pH stabilizers pre...
The mixture of our invention is a solid powder which may be stored for long periods of time without any danger of deterioration or undue loss in active oxygen content. One of the objects of this invention is to prepare a composition which will utilize the very desirable active oxygen-...
Also, precursor systems have large formulation space requirements so that a significant proportion of a laundry powder must be devoted to the bleach components, leaving less room for other active ingredients and complicating the development of concentrated powders. Moreover, precursor systems do not ...
