摘要:
It is intended to provide a dental plaque detection system and a dental plaque detection method whereby dental plaque can be detected at a high accuracy while relieving the staining in parts (interdental space, gingiva, etc.) other than dental plaque. This dental plaque detection system comprises a dental plaque-staining agent containing at least one member selected from among a yellow pigment originating in red koji mold, a turmeric extract and curcumin and a light-emission unit (10) emitting light of from 250 to 500 nm in wavelength toward a subject (40) in the oral cavity having the dental plaque-staining agent attached thereto. The dental plaque detection method comprises attaching the dental plaque-staining agent having the composition as described above to a subject in the oral cavity and then irradiating the subject with light of from 250 to 500 nm in wavelength.
摘要:
The present invention is to provide a conductive masterbatch using a polyamide resin, the conductive masterbatch that has an excellent kneadability/manufacturability and formability and an excellent dispersibility of conductive fillers such as a carbon black, and shows stable conductivity even when a large amount of such conductive fillers are contained therein, and a resin composition containing the conductive masterbatch. That is, the present invention is to provide the conductive masterbatch, which includes at least a conductive filler selected from carbon blacks and carbon nanotubes, a polyamide resin, and a copolymer which contains at least a vinyl monomer having a functional group reactive with the polyamide resin and a styrene as monomer units, and in which the content of the conductive filler is in the range of 10% by mass to 40% by mass, and the resin composition containing the conductive masterbatch.
摘要:
A base for electric insulating oil comprising an esterification product from a C 8 -C 20 higher fatty acid and a C 6 -C 14 branched aliphatic monohydric alcohol; or a base for electric insulating oil comprising an esterification product from a mixed fatty acid derived from palm oil and/or mixed fatty acid derived from soybean oil and a C 1 -C 5 aliphatic monohydric alcohol or C 6 -C 14 branched aliphatic monohydric alcohol. The thus provided base for electric insulating oil excels in viscosity, fluidity, chemical stability, etc. and is capable of satisfactorily exhibiting electrical characteristics of electric insulating oil.
