Use of silicon-containing particles for protection against ultraviolet, production method of particles, and preparation containing particles

PROBLEM TO BE SOLVED: To develop a novel ultraviolet filter which is preferably dissolvable biologically or should be dissolvable in organisms, although it should not be dissolved by ultraviolet.SOLUTION: A silane mass flow is supplied to a plasma discharge apparatus with a silicon-halogenated compound, e.g., an impure ingredient which is a compound containing chlorine and bromine, wherein it is reacted e.g., in a high voltage pulse discharge.SELECTED DRAWING: None
