Title:
NANO-FREE SILICA PARTICLES AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/025032
Kind Code:
A1
Abstract:
The present invention relates to nano-free silica particles and a preparation method therefor and, specifically, to a silica particles which are spherical silica for cosmetics, having a diameter of 1-30 um and being obtained using water glass, and which are nano-free according to the results of measurement using a scanning electron microscope (SEM). Cosmetics containing the silica particles, according to the present invention, comprise no nanomaterials so that the harmful effects of nanomaterials can be prevented, and have high flowability so that the texture thereof can be improved.
