Ultraphosphate, a potent stain control agent that is effective for both stain removal and prevention of stain deposition.

Polyphosphate is a phosphate polymer which is effective for stain removal and prevention of stain deposition. Ultraphosphate belongs to the polyphosphate group and has a highly branched mesh-like structure. To evaluate stain control ability of ultraphosphate, we used HAP powder, glass-ionomer cement and detached human teeth for models of in vitro stain control experiments. When using HAP powder...

Stain removal from a silicone maxillofacial elastomer.

In this study, environmental stains were removed from maxillofacial elastomers by solvent extraction. Silastic 44210, an RTV silicone with proven color and physical property stability, was stained with lipstick, disclosing solution, and methylene blue. These stains were then removed by solvent extraction with each of four chemically dissimilar solvents, namely: toluene, benzene, 1,1,1-trichloro...

Silicone Softeners for Stain Repellent and Stain Release Fabric Finishing

During the last few years the use of fluorochemicals to provide stain repellency and/or stain release properties to apparel goods has rapidly grown. The use of fluorochemicals as well as durable press resins, however, has a detrimental effect on the fabric softness. Providing premium softness is key to satisfy the highly demanding aesthetic requirements of many of today’s apparel products. Alth...

A rapid stain for Pneumocystis.

Step in procedure Supernatant haemoglobin (g) After thawing 0 45 First wash 1 6 Second wash 0-45 Third wash 0-12 Final product 0-023 After incubation 0-05 stability of the red cell preparation after incubation at 37°C for 30 minutes. Recovery was calculated from the supernatant haemoglobin in relation to the initial total haemo-globin after thawing (table 2). Mean (SD) recovery was 70% (13 3), ...
