Abstract:
The invention relates to a hair dye composition having markedly high dyeing power, less color fade over time, and undergoes a small change in the color tone of the dye even after storage.
Abstract:
Provided is a hair dye composition containing a direct dye (1), (2) or (3). This hair dye composition has markedly high hair dyeing power, has less color fade over time and undergoes a small change in the color tone of the dye even after storage. wherein, R1 represents a (substituted) aryl group, R2, R4 to R6, R8 and R9 each represents H, a (substituted) C1-6 alkyl group or a (substituted) aryl group, R3 and R7 each represents a (substituted) aryl group, R10 to R12 each represents a (substituted) C1-6 alkyl or (substituted) aryl group, rings A to G each represents a benzene ring which may be substituted by a (substituted) amino group, (substituted) C1-6 alkyl group, C1-6 alkoxy group or halogen atom or may further be cyclocondensed with a benzene ring, and X− represents an anion.
Abstract:
The invention relates to a hair dye composition comprising (A) an acid dye and (B) an alkylene carbonate having 3-5 carbon atoms in total, said composition exhibiting a pH of 2-6, and having a buffer capacity of 0.007-0.5 gram equivalent/L, and to a method of dyeing hair using the hair dye composition. The hair dye composition is excellent in hair-dyeing ability without coloring the scalp and skin and has good fastness to shampoo and the like.
Abstract:
Disclosed herein is a hair dye composition comprising (A) benzyloxyethanol and/or benzyl alcohol, (B) propylene carbonate and (C) an acid dye and having a pH of 2.0 to 6.0. The composition has excellent hair-dyeing ability and good fastness to shampoo.
Abstract:
An .alpha.-(alkylcyclohexyloxy)-.beta.-alkanol of formula (1) ##STR1## wherein at least one of R.sup.1, R.sup.2, R.sup.3, R.sup.4, and R.sup.5 is the group ##STR2## wherein R.sup.9 and R.sup.10 are the same or different alkyl groups having 1 to 4 carbon atoms or are coupled with each other to form a cycloalkyl group, and R.sup.11 is a hydrogen atom or an alkyl group having 1 to 4 carbons or is a hydrogen atom when R.sup.9 and R.sup.10 form the cycloalkyl group, and the remaining R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 groups are hydrogen atoms or methyl groups, and wherein R.sup.6, R.sup.7 and R.sup.8 are hydrogen atoms or the same or different alkyl groups having 1 to 6 carbon atoms.
Abstract:
There is provided a head hair dyeing method using a two-part hair dye composition which contains: a first part containing a first part stock solution and a propellant, the first part stock solution containing an alkali agent and a surfactant; a second part containing a second part stock solution and a propellant, the second part stock solution containing hydrogen peroxide and a surfactant; and two aerosol containers for respectively discharging the first part and the second part as foam, the method including respectively discharging the first part and the second part as foam from the containers, applying the foam mixture to the head hair, and then re-foaming the mixture on the head hair.
Abstract:
A two-part hair dye including a first part containing an alkali agent, a second part containing hydrogen peroxide, and a non-aerosol foamer vessel to discharge in the form of foam a liquid mixture of the first part and the second part, wherein the liquid mixture contains anionic surfactant(s) selected from the following components (A1) to (A3), or the following components (A4) and (A5): (A1) a carboxylate type anionic surfactant; (A2) a sulfonate type anionic surfactant; (A3) a phosphate type anionic surfactant; (A4) an ionic surfactant; and (A5) a fatty acid alkanolamide.
Abstract:
Provided is a hair bleach or dye composition containing an amino-modified silicone, a highly polymerized silicone having a number-average degree of polymerization of 1000 or greater, a cationic polymer and an oxidizing agent. The hair bleach or dye composition of the present invention does not give a discomfort upon washing or shampooing of the treated hair, can bleach or dye the hair uniformly from root to tip without damaging the hair by this treatment, add to the hair a good color and luster, and a good feel of the hair, manageability and hair retention after drying, and is also good in durability of these effects and stability.
Abstract:
Provided is a hair dye composition containing a direct dye (1) or (2). The hair dye composition has markedly high hair dyeing power, has less color fade over time and undergoes a smaller change in the color tone of the dye after storage. [R1, R2 and R3 are the same or different and each independently represents a C1-3 alkyl group and benzene ring A or B may contain a nondissociative substituent].
Abstract:
The present invention provides a treatment composition for dyed hair which effectively prevents color fading of the dyed hair, to thereby maintain the color of the dyed hair for prolonged periods. The composition contains the following components (A), (B), and (C): (A) an organic solvent selected from among aromatic alcohols, lower alkylene carbonates, N-alkylpyrrolidones, and formamides; (B) an organic carboxylic acid or a salt thereof; and (C) a lower alcohol, a polyhydric alcohol, or a lower alkyl ether of a polyhydric alcohol; wherein the pH of the composition falls within the range of 1-6 inclusive, and the composition does not contain any dye. In use, the composition is applied to hair dyed with an acid-dye-type hair dye composition; and then the hair is left to stand for 5-30 minutes at 20-60° C., followed by washing.
