Description

  The present invention relates to a cosmetic containing hydrophobic spherical silica fine particles.

  Conventionally, cosmetics blended with powder have been widely used. However, these are particularly poor in extensibility and a feeling of rubbing against the skin, and improvements are required.

In addition, cosmetics containing spherical hydrophobic silica fine particles have also been proposed (see Patent Document 11: Japanese Patent Laid-Open No. 2000-264815), and although the extensibility and the feeling of coating are improved, there is a risk of skin penetration of 100 nm. No mention is made of less than fine powder.

Hydrophobic spherical silica fine particles The hydrophobic spherical silica fine particles used in the present invention have a particle diameter of 100 nm or more, and if they do not include particles having a particle diameter of less than 100 nm, the entire range of particles usable in cosmetics. Diameter can be applied. In recent years, it is feared that particles with a particle size of less than 100 nm may permeate into the skin, and even when silica is dry blended, there is a concern about the safety of nanomaterials with a particle size of less than 100 nm. The opinion of the alert is also issued from the place. For example, the handling of carbon nanotubes and silica nanotubes having a small average particle diameter has recently become very nervous.

  The average particle diameter (volume cumulative average particle diameter) of the hydrophobic spherical silica fine particles is preferably 150 to 10,000 nm, and more preferably 160 to 1,000 nm. If the average particle size is less than 150 nm, there may be a trace amount of particles having a particle size of 100 nm, and if the average particle size exceeds 10,000 nm, the uniform dispersibility and the feeling of use may be deteriorated. The transparency of the fine particles may be impaired. In the present invention, the particle diameter is a value measured with a laser diffraction / scattering particle size distribution measuring device, and “average particle diameter” indicates “volume cumulative average particle diameter”. “Particle diameter”.

  When the hydrophobic silica fine particles are spherical, when applied to a cosmetic, it acts as a kind of ball bearing when the cosmetic is applied, and has the effect of dramatically improving the slipperiness of the cosmetic substrate. In addition, on the surface of the cosmetic coating film, an effect (soft focus effect) that effectively scatters light and hides skin shape troubles related to light reflection is exhibited. The term “spherical” as used herein refers to a true spherical shape or a substantially spherical shape, but a true spherical shape is preferable in order to achieve the effects of the present invention. In the case where light related to the effect of concealing skin form trouble (soft focus effect) is effectively scattered and light reflection is strongly desired, the particles are preferably aligned. In that case, “monodisperse” is preferred. “Monodisperse” means that the particle size distribution is narrow, and the coefficient of variation of the particle size (value expressing the standard deviation of the particle size as a percentage based on the average particle size) is preferably 10% or less, preferably 5% or less. Is more preferable. In order to obtain the hydrophobic spherical silica fine particles used in the present invention in a monodisperse form, for example, after obtaining hydrophilic spherical silica fine particles as a starting material as monodisperse particles, the spherical particles are subjected to a hydrophobic treatment. Obtainable.

A legal method may be used, and commercially available spherical particles may be classified by a sieve or the like.
