Problems solved by technology

[0004] However, in order to obtain a redispersion type powder dispersion cosmetic that exhibits advantages such as an excellent feeling of use when applied to the skin and has an effect of dissolving and removing horn plugs, if the redispersion type powder containing powder components such as spherical cellulose powder If organic acids such as citric acid and / or their salts are mixed in dispersion cosmetics, it will not be possible to obtain a sufficient feeling of use even though it contains powder ingredients
In addition, even if the powder component is shaken during use, it tends to remain on the bottom of the container, and the powder tends not to be sufficiently redispersed
