Abstract: Provided are a silicon-oxide-coated zinc oxide capable of suppressing the elution of zinc ions from zinc oxide particles, a method for manufacturing the same, a silicon-oxide-coated-zinc-oxide-containing composition, and a cosmetic. The silicon-oxide-coated zinc oxide is a silicon-oxide-coated zinc oxide formed by coating the surfaces of zinc oxide particles with a silicon oxide coating, in which the average particle diameter of the zinc oxide particles is in a range of 1 nm or more and 50 nm or less, when the abundance ratio of silicon in the silicon oxide coating in a Q3 environment is indicated by Q3, and the abundance ratio in a Q4 environment is indicated by Q4, Q3+Q4?0.6 and Q4/(Q3+Q4)?0.5, and furthermore, the decomposition ratio of Brilliant Blue generated by the photocatalytic activity of the zinc oxide particles is 3% or less.
