Abstract: A sanitizer composition in an emulsion formulation is disclosed. The sanitizer composition contains: ethanol; a surfactant; oil; and water. The ethanol content is greater than 10% by weight on the basis of total weight of the sanitizer composition. The surfactant 5 may be one or more of a lecithin-based surfactant and a sorbitan-based surfactant, and the oil may be one or more selected from the group consisting of C12-15 alkyl benzoate, coconut oil, olive oil, and palm oil. The sanitizer composition has an effect of providing a high moisturizing feeling while containing a large amount of 10 ethanol, and of implementing an emulsion formulation such as a lotion.

Abstract: The present disclosure provides porous composite powder which includes biodegradable polymer particles with a porous structure having positive charges dispersed uniformly thereon and further includes inorganic particles. The porous composite powder adsorbs and removes fine particulate matter remaining in the skin and skin pores effectively through ionic bonding, while maintaining a spherical shape. The present disclosure also provides a method for preparing porous composite powder for adsorption of fine dust including particles forming a composite homogeneously, while maintaining a spherical shape, through a single process.

Abstract: Disclosed is a tooth whitening apparatus including: a mouthpiece to which a gel for applying hydrogen peroxide is applied; a lamp unit disposed at an inner tip of a grip case to whiten teeth by using light; a secondary battery disposed on a lower side of a PCB control board inside the grip case; a vibration device disposed at an upper side of the grip case to be operated by an on-off switch; and a USB port charging unit disposed at a rear side of the grip case to charge the secondary battery.
