Hair dye agent based on a developer-coupler system reacting with peroxide contains (a) at least one developer selected from 2-(2'-hydroxyethylamino)-5-aminotoluene (Ia), 1-amino-4-bis-(2'-hydroxyethyl)aminobenzene (Ib) and 2-(2,5-diaminophenyl)ethanol (Ic) and their water-soluble salts; (b) 5-amino-2-methylphenol (II); and (c) 4-amino-3-methylphenol (III).

Hair dyeing composition

A hair dye composition containing a triazene dissociative direct dye represented by general formula (1): A-N=N-NH-B (1) wherein A and B are each a monocyclic or a bicyclic aromatic heterocyclic group that may have a substituent or a monocyclic or a bicyclic aryl group that may have a substituent and contain none of a carboxy group, a sulfo group and a quaternary ammonium group; and A and B each bind to a triazene-1,3-diyl group represented by -N=N-NH- via a carbon atom within A and B each. A and B may be the same or different.

Hair-dye composition

The present invention is for cosmetic compositions where upon application forms a film. The applied composition provides significant wear benefits improvement to the user. These composition comprise the combination of organosiloxane resins and fluid diorganosiloxane resins with a volatile carrier.

Transfer resistant cosmetic compositions

An anhydrous cosmetic stick composition with improved transfer resistance comprising, by weight of the total composition: a) 10-70 % of a volatile solvent, b) 0.1-40 % of a polymeric organosiloxane emulsifier containing at least one hydrophilic radical and at least one lipophilic radical.

Transfer resistant cosmetic stick compositions with semi-matte finish

A cosmetic composition comprising: a) 1-70% volatile solvent; b) 0.1-15% silicone resin; c) 10-45% wax; d) 5-50% powder; and e) 1-30% oil has improved transfer resistance over previously-known cosmetics. They may be prepared by grinding some of the dry components with the solvent and resin, adding the wax and oil followed by the remainder of the dry components. When filled into suitable receptacles, the composition may be used as a concealer, blusher, eye shadow, foundation, lipstick or the like.

Cosmetic compositions with improved transfer resistance.

A hair dye composition which comprises a direct dye selected from the compounds represented by the formula (I). This hair dye composition has markedly hair dyeing power, has less color fade over time and does not undergo a change in the color shade of the dye even after storage. Awherein, R represents H, (substituted) lower alkyl or aralkyl, R represents (substituted) lower alkyl, aralkyl or (substituted) phenyl, R represents H, halogen, lower alkyl or lower alkoxy, R represents lower alkyl or (substituted) phenyl, R represents H, halogen, lower alkyl or lower alkoxy, R and R each represents lower alkyl, R represents H, methyl or cyano, and A represents anion.U

Use of a compound for dyeing hair

PROBLEM TO BE SOLVED: To provide an ester oil agent that can satisfy all of the requirements including compatibility with silicones, solubilization of poor soluble substances, high safety, for example, reduced smell, low skin irritation, good feeling in use, as well as high time-passage and oxidation stability, pale coloration, keeping liquid state even at low temperatures. SOLUTION: The diester is obtained from a 6-9C saturated and branched chain dihydric alcohol and neopentanoic acid or the oil agent comprises the diester. Further, a cosmetic or an external preparation for skin containing the diester are used. By the invention, an oil agent attaining the above-subject is obtained. COPYRIGHT: (C)2005,JPO&NCIPI

Diester and oil agent and cosmetic and external preparation for skin

PROBLEM TO BE SOLVED: To obtain the subject composition while suppressing the coloring of skin, excellent in dyeing property to hair and also having a good shampoo fastness by containing an acid dyestuff and a specific alkylene carbonate for specifying pH and a buffering function. SOLUTION: This hair dyeing agent composition is obtained by containing (A) 0.2-5 wt.% acid dyestuff and (B) 9.5-50 wt.% alkylene carbonate (e.g.; propylene carbonate) so as to make pH at 2.0-6.0, preferably 2.0-5.0 and more preferably 2.5-4.0, and ≥0.007 g equivalent/L and <0.2 g equivalent, preferably, ≥0.01 g equivalent/L and <0.2 g equivalent buffering function. The buffering function is a value obtained by using the formula: Buffering function = |dCB /dpH| [CB is an ionic concentration (g equivalent /L) of a base] based on the concentration of the base required for increasing pH of a 10% aqueous solution of the composition at 250°C by 1 from its initial value.

Hair dyeing agent composition

An amine derivative of following general formula (I) or (II) (wherein R1 represents a heteroatom-containing C?1?-C40 hydrocarbon group which may have a ring structure, etc.; R?2 to R6? each represent a C?1?-C10 hydrocarbon group, hydrogen, etc.; A?1? represents (i) or R?15-Z-R16(CH?2)n-; B1 represents hydrogen, a C?1?-C10 hydrocarbon group, nitrogen, etc.; and C?1? represents hydrogen, a C?1?-C10 hydrocarbon group, nitrogen, alcohol residue, phosphoric acid residue, etc.); a dermatologic preparation containing the same; and a process for producing the amine derivative. The amine derivative has excellent effects of smoothing wrinkles and improving keratodermia.
