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:
A base for electric insulating oil comprising an esterification product from a C8-C20 higher fatty acid and a C6-C14 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 C1-C5 aliphatic monohydric alcohol or C6-C14 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.
