摘要:
Described herein is a method of increasing the uptake and lastingness of hair care benefit agents. The method includes applying to the hair a hair care composition including one or more hair health compounds, and rinsing the hair with water. The one or more hair health compounds each include a benefit agent, one or two permanent cations, and one to four incipient cations, and a hydrophobe, that may be used to attach the benefit agent to the incipient cation. The one to four incipient cations are pendant to the core structure and are neutral. The one or more hair health compounds enter the hair shaft after the hair care composition is applied to the hair. The composition has a pH of from about 3.5 to about 11. The pH of the hair after rinsing is from about 3.5 to about 6.

Disclosed are novel stable violet-blue to blue imidazolium azo compounds that have a simplified chromophore and high relative solubility in aqueous systems, and that are stable under the conditions of use and storage. The compounds are useful for dyeing fibers such as fabrics and hair, as fabric hueing agents, and as dyes for other keratinaceous materials. Also disclosed are laundry care compositions comprising the imidazolium azo compounds and methods of using the compositions.
摘要:
Hair care composition comprising from about 0.1% to about 20% of a sulfopropyl(meth)acrylate compound, an alpha methylene lactone, or a mixture thereof, wherein the sulfopropyl(meth)acrylate compound and the alpha methylene lactone each have a molecular weight of less than 500 grams/mole; and a dermatologically acceptable carrier.
摘要:
Described herein is a hair treatment composition for the hair. The hair treatment composition includes one or more fluorescent compounds and one or more additional ingredients. The one or more fluorescent compounds each include a fluorophore, one or two permanent cations, and one to four incipient cations. The one to four incipient cations are pendant to the core structure and are neutral. The one or more fluorescent compounds enter the hair shaft after the hair treatment composition is applied to the hair. The hair treatment composition has a pH of from about 7 to about 11.

Described herein is a method of treating the hair. The method includes applying to the hair a hair treatment composition including one or more fluorescent compounds and rinsing the hair with water. The one or more fluorescent compounds each include a fluorophore, one or two permanent cations, one to four incipient cations, and one or more hydrophobic moieties. The incipient cations are pendant to the core structure and are neutral. The one or more fluorescent compounds enter the hair shaft after the hair treatment composition is applied to the hair. The hair treatment composition has a pH of from about 7 to about 11. The pH of the hair after rinsing is from about 3.5 to about 6. The rinsing of the hair causes one or more of the one to four incipient cations to change from neutral to positively charged inside of the hair shaft.
摘要:
A process for the preparation of 2-substituted-1,4-benzenediamines, a cosmetically acceptable salt thereof, or mixture thereof. The process according to the present invention is a particularly cost effective process in that it avoids sophisticated chemical steps which requires special equipment or expensive catalysts and in that it comprises a recycling step of one of the starting materials, namely the 2-substituted aniline.
摘要:
A hair colorant composition comprises 2,6-diaminopyridine coupler in combination with 2-methoxymethyl-1,4-diaminobenzene developer. A kit for coloring hair comprises the hair colorant composition. A method of treating hair comprises applying the hair colorant composition to hair.
摘要:
A process for synthesizing 2-methoxymethyl-1,4-benzenediamine (V-a), its derivatives of formula (V) and the salts thereof, which comprises a radical halogenation step of formula (II). The final product can be 2-methoxymethyl-1,4-benzenediamine of formula (IV-a).
