A document classifying device () includes: a unit () configured to acquire information regarding a to-be-classified document set in which classification codes based on multi-viewpoint classification are assigned to each document in advance; a unit () configured to generate a multi-dimensional feature vector for each document in the to-be-classified document set, the multi-dimensional feature vector having, as elements, all or part of the classification codes assigned to the to-be-classified document set; classifying unit () configured to classify the to-be-classified document set using the feature vector of each document; and a generating unit () that generates document classification information indicating a result of the classification.

Document classifying device

A relation equation between wave information on unpermed hair strands and evaluation values of appearance of whole hair selected from among gloss of the whole hair, order of alignment of the hair strands, and frizziness of the hair strand is acquired from a plurality of subjects. Based on the relation equation, the appearance of whole hair of an arbitrary subject is evaluated from wave information on a hair strand of the arbitrary subject. This allows an objective evaluation of the gloss of whole hair, the order of alignment of hair strands, or the frizziness of the hair strand by a simple technique, and also allows an objective evaluation corresponding to cosmetic specialists' evaluations in terms of equivalent age.

Hair evaluation method and system

The present invention relates to a hair dye composition containing a dissociative azo dye which has high dyeing power, is capable of imparting a vivid color to the hair firmly, has excellent fastness to light, shampooing, sweat, friction, and heat, and fades less with the passage of time because the dye is stable against an alkali agent or an oxidizing agent and does not decompose during hair dyeing; and a hair dyeing method using the hair dye composition.

Hair dye composition

A non-oxidative hair dye composition containing the components (a) and (b): (a) one or two or more kinds of a glycylglycine derivative represented by the following formula (1) and having two or three amino acid residues or salts thereof, and wherein Y represents an amino acid residue or a bivalent group represented by the formula (2); and (b) a direct dye; Wherein symbol * and R, X, n and m are defined in the claims and in the disclosure.

Non-oxidative hair dye composition

A hair dye composition containing an azo dye (1) or a salt thereof, (wherein Rto Rrepresents H, aliphatic hydrocarbon group, aryl group, halogen atom, acyl group, cyano group, acylamino group, or the like, wherein Rand R, and/or Rand Rmay be coupled to form a 5- or 6-membered ring; X represents C or N, with the proviso that when X represents C, n stands for 1, and when X represents N, n stands for 0; A, A, Aand Aeach represents N or represents C substituted by Y or having H, with the proviso that at least one of A, A, Aand Ais a nitrogen atom; and Y represents a substituent with the proviso that m stands for an integer from 0 to 3).

A hair dye composition containing an azo dye (1) or a salt thereof: wherein R represents a coupler moiety, Rand Reach independently represent &#x2014;SOM, &#x2014;SONRRor a hydrogen atom, R, Rand Reach independently represent a hydrogen atom or a substituent, and M represents a hydrogen atom, metal atom or ammonium, with a proviso that Rand Rare not hydrogen atoms at the same time.

Treatment composition for dyed hair

Singlet oxygen quenchers containing as an active component a compound represented by the following formula or (2): ##STR1## wherein each of R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.10 and n are as described herein, and external compositions containing these compounds are provided for the prevention and treatment of various forms of damage to living bodies caused by singlet oxygen, and are thus quite useful as antiinflammation agents, anti-aging agents, agents preventing darkening of the skin, agents preventing protein denaturation, inhibitors against formation of sunburn cells, agents preventing lipid peroxidation, agents preventing DNA damage, and particularly in the fields of medicines and cosmetics as external compositions for the skin.

Singlet oxygen quenchers and external compositions containing the same

A 4,4-Dimethyl-1-phenylpentane-1,3-dione derivatives represented by the following formula (1): ##STR1## wherein all symbols are defined in the disclosure, is disclosed. An ultraviolet ray absorbent and a cosmetic comprising the derivative are also disclosed. The derivative of the present invention have excellent ultraviolet ray absorbing performance and superior light stability, and the ultraviolet ray absorbent and cosmetic comprising the derivative have excellent effect to prevent sunburn.

4,4-dimethyl-1-phenylpentane-1,3-dione derivative and UV ray absorbent

A novel aroyl ketone derivative represented by formula (I) is disclosed.
