Abstract:
(EN) Provided are surface-treated zinc oxide particles stably displaying high ultraviolet ray-shielding properties. Also provided are a dispersion liquid and a cosmetic that include said surface-treated zinc oxide particles. In addition, zinc oxide particles are provided whereby said surface-treated zinc oxide particles can be suitably produced. In the surface-treated zinc oxide particles, the particle surface of the zinc oxide particles has been treated using a silane coupling agent having an alkoxy group. The zinc oxide particles fulfil formula (1). S·M/σ2 ≥ 0.05 … (1) (S indicates the surface area of the zinc oxide particles (unit: m2/g), M indicates the Na content in the zinc oxide particles (unit: mg/kg), and σ indicates slurry conductivity (unit: μS/cm) when 10 parts by mass of zinc oxide particles and 90 parts by mass of pure water are mixed for an hour.)
(FR) L'invention concerne des particules d'oxyde de zinc traitées en surface, présentant de manière stable des propriétés de protection contre les rayons ultraviolets. L'invention concerne également un liquide de dispersion et un produit cosmétique comportant lesdites particules d'oxyde de zinc traitées en surface. De plus, l'invention concerne des particules d'oxyde de zinc grâce auxquelles lesdites particules d'oxyde de zinc traitées en surface peuvent être produites de manière appropriée. Dans les particules d'oxyde de zinc traitées en surface, la surface de particule des particules d'oxyde de zinc a été traitée à l'aide d'un agent de couplage silane comprenant un groupe alcoxy. Les particules d'oxyde de zinc satisfont à la formule (1). S·M/σ2 ≥ 0,05 … (1) (S indique la surface des particules d'oxyde de zinc (unité : m2/g), M indique la teneur en Na dans les particules d'oxyde de zinc (unité : mg/kg), et σ indique la conductivité d'une suspension (unité : μS/cm) lorsque 10 parties en masse de particules d'oxyde de zinc et 90 parties en masse d'eau pure sont mélangées pendant une heure.)
(JA) 安定的に高い紫外線遮蔽性を示す表面処理酸化亜鉛粒子を提供する。また、このような表面処理酸化亜鉛粒子を含む分散液、化粧料を提供する。また、このような表面処理酸化亜鉛粒子を好適に製造可能な酸化亜鉛粒子を提供する。酸化亜鉛粒子の粒子表面がアルコキシ基を有するシランカップリング剤で処理された表面処理酸化亜鉛粒子であって、酸化亜鉛粒子が、下記式(1)を満たす表面処理酸化亜鉛粒子。 S・M/σ≧0.05 …(1) (Sは酸化亜鉛粒子の比表面積(単位:m/g)、Mは酸化亜鉛粒子のNa含有量(単位:mg/kg)、σは酸化亜鉛粒子10質量部と純水90質量部とを1時間混合したスラリーの導電率(単位:μS/cm)である。)
