Problems solved by technology

However, in the present invention in which an antibacterial zeolite is mixed as an insoluble powder in an ethanol base, sufficient redispersibility of the antibacterial zeolite powder cannot be obtained even if a divalent metal salt of a fatty acid is mixed alone as a dispersant. identified by the inventor

preparation example Construction

[0040] As a preparation method of an antibacterial zeolite, it manufactures as follows, for example. That is, the zeolite is brought into contact with a mixed aqueous solution containing antibacterial metal ions such as silver ions, copper ions, and zinc ions prepared in advance to replace the ion-exchangeable ions in the zeolite with the ions. The contact can be performed at 10-70° C., preferably 40-60° C., by batch or continuous (eg column method) for 3-24 hours, preferably 10-24 hours. It should be noted that the pH of the above mixed aqueous solution is preferably adjusted to 3-10, preferably 5-7. This adjustment is preferable since it is possible to prevent silver oxides and the like from being precipitated on the surface of the zeolite or in the pores. In addition, each ion in the mixed aqueous solution is usually supplied in the form of a salt. For example, silver ions can be used: silver nitrate, silver sulfate, silver perchlorate, silver acetate, silver diammonium n...

Abstract

Disclosed is a two-layer type powder cosmetic preparation containing (a) an antibacterial zeolite powder and (b) 50-90% by mass of ethanol that serves as a base agent, which is characterized by additionally containing (c) glutathione and / or L-cysteine and (d) zinc paraphenolsulfonate. The two-layer type powder cosmetic preparation exhibits excellent re-dispersibility and discoloration prevention of the antibacterial zeolite powder (a). The two-layer type powder cosmetic preparation contains ethanol as a main base agent and has an antibacterial zeolite powder, which is insoluble in ethanol, blended therein. The two-layer type powder cosmetic preparation exhibits extremely excellent re-dispersibility of the antibacterial zeolite powder (a), and is capable of preventing discoloration of the antibacterial zeolite powder (a) when the cosmetic preparation gets on clothes.

Description

technical field [0001] The present invention relates to two-layer powder cosmetics. More specifically, it relates to a two-layer powder cosmetic having ethanol as a main base and an insoluble antibacterial zeolite powder mixed in the ethanol base, and the redispersibility of the antibacterial zeolite powder is extremely high when the two-layer powder cosmetic is used. It is excellent and can certainly prevent discoloration of antibacterial zeolite powder when it is attached to clothes. Background technique [0002] Antibacterial zeolites used as deodorant cosmetics may adhere to clothing with sweat and cause discoloration. In addition, when using the double-layered powder cosmetics mixed with antibacterial zeolite powder, it is necessary to redisperse and uniformly disperse the antibacterial zeolite powder separated into two layers. It should be noted that the two-layer powder cosmetic refers to a liquid preparation mixed with powder. If the two-layer powder cosmetic is le...
