Customized cosmetic kit

Abstract

A cosmetic kit provides cosmetics which are customized (personalized) for each user and a cosmetic provision device which uses the kit to supply customized cosmetics. The cosmetic kit includes a plurality of cosmetic bases, and is used for customized cosmetics which are prepared by mixing the plurality of cosmetic bases in accordance with recipe information determined on the basis of user unique information. The cosmetic kit provides that when a container containing at least two cosmetic bases selected from the plurality of cosmetic bases is rotated at a prescribed speed, and a near-infrared measurement of the bases in the container is performed at prescribed time intervals, the time (T) required to obtain an nth measurement, in which the rate of change between the absorbance in the nth measurement and the absorbance in the previous ((n−1)th) measurement is 100%±5%, and the rate of change with respect to the absorbance in the following ((n+1)th) measurement is 100%±5%, is not more than 35 minutes.

1 . A cosmetic kit, for use in a preparation of a customized cosmetic:
 wherein said cosmetic kit comprises a plurality of cosmetic bases, and said customized cosmetic is prepared by mixing said plurality of cosmetic bases in accordance with a recipe information determined based on a user-unique information; and   wherein said cosmetic bases satisfy the following condition:
 when a container containing at least two cosmetic bases selected from said plurality of cosmetic bases is rotated at a predetermined speed to carry out a near-infrared ray measurement of said selected cosmetic bases in said container at predetermined time intervals, a time (T) required reaching an (n)th measurement is not more than 35 minutes, wherein said (n)th measurement is a first measurement achieving both of a first change ratio between absorbance in said (n)th measurement and absorbance in a previous (n−1)th measurement and a second change ratio between absorbance in said (n)th measurement and absorbance in a next (n+1)th measurement becomes 100%±5%. 
   
     
     
         2 . The cosmetic kit, according to  claim 1 , wherein:
 said user-unique information comprises:
 at least one selected from a group consisting of a user attribute information related to user's attributes, an environmental information related to user's environment, an action information related to user's action, a psychosomatic information related to user's psychosomatic, a skin information related to user's skin, and an information related to cosmetics that a user has uses. 
   
     
     
         3 . The cosmetic kit, according to  claim 1 , wherein:
 said recipe information comprises at least one selected from a group consisting of a usage amount, a blending ratio, and a total amount of respective cosmetic bases.   
     
     
         4 . The cosmetic kit, according to  claim 1 , wherein:
 each base of said plurality of cosmetic bases is included in an individual cartridge.   
     
     
         5 . The cosmetic kit, according to  claim 4 , wherein:
 said cartridge is a cartridge applicable to a cosmetic dispenser comprising:
 a plurality of cartridge slots detachably configured to hold said cartridges containing said cosmetic bases; and 
 a means for dispensing respective cosmetic bases; wherein said means provides said cosmetic bases contained in respective cartridges held by respective cartridge slots based on said recipe information including a usage amount of each cosmetic base determined based on said user-unique information. 
   
     
     
         6 . The cosmetic kit, according to  claim 5 , wherein:
 said cosmetic dispenser is communicably connected with an information processing apparatus capable of processing an information based on said user-unique information.   
     
     
         7 . The cosmetic kit, according to  claim 1 , wherein:
 said plurality of cosmetic bases includes at least a first base and a second base; and   said first base comprises a first thickener, said second base comprises a second thickener, and said first thickener and said second thickener are made from respectively different substances.
