Abstract:
A hair dye composition comprises the following ingredients (A) and (B): (A) a compound having a 5- or 6-membered lactone skeleton, and (B) an acid dye; and having a pH of from 2 to 6 and a buffer capacity not lower than 0.004 gram equivalent/L but lower than 0.2 gram equivalent/L as measured in a form of a tenfold dilute aqueous solution. This hair dye composition does not cause staining to the skin, is excellent in dyeing properties for hair, is good in the fastness to shampoo, and does not give off gas through hydrolysis in an acidic range.
Abstract:
A composition for hair bleaching or hair dyeing which contains amino-denatured silicone, a silicone high-polymer having a degree of number-average polymerization of 1000 or above, a cationic polymer and an oxidant. By treating the hair with the use of the above composition for hair bleaching or hair dyeing, a favorable texture is presented during rinsing and shampooing without damaging the hair. The hair can be uniformly bleached or dyed from the root to the end thereby. Moreover, the hair thus treated shows an excellent color and gloss and, after drying, it shows a favorable texture and moisture retention and can be easily styled. Moreover, these favorable characteristics are sustained over a long time and a high stability is obtained.
Abstract:
A sheet-like hair care product including (A) a substrate sheet containing cellulosic fibers and having a bending resistance of 10 to 70 mm measured by the 45° cantilever method in accordance with JIS L1096:2010 and (B) a liquid cosmetic composition. The substrate sheet (A) is impregnated with 1 to 50 g of the liquid cosmetic composition (B). The substrate sheet impregnated with the liquid cosmetic composition is preferably packaged in a packaging container having an access opening with an area of 25 to 4000 mm 2 and an openable and closable lid sealing the contents.
Abstract:
A leave-on type hair cosmetic composition having the following two layers A and B: Layer A of an oil layer containing the following component (a) in an amount of 0.5-40% by mass in the hair cosmetic composition, (a) a highly polymerized silicone selected from dimethicone and dimethiconol and having a number average degree of polymerization of 1,000-20,000; and Layer B of a water layer containing the following components (b) and (c), (b) a water-soluble polymeric thickening agent, and (c) water.

Abstract:
PROBLEM TO BE SOLVED: To provide a hair cosmetic enabling the compounding of a large amount of an oily layer, free from stickiness of oil solution, easily miscible in use, and which is uniformly applicable to the hair, to collect finished hair, and is free from stickiness and has dry smooth feeling. SOLUTION: A leave-on-type hair cosmetic has two layers including the following layers A and B. The layer A is an oily layer including a component (a) containing a highly polymerized silicone having a number average polymerization degree of 1,000-20,000 and selected from dimethicone and dimethiconol in an amount of 0.5-40 mass% relative to the total amount of the hair cosmetic, and the layer B is an aqueous layer containing components: (b) a water-soluble polymeric thickening agent; and (c) water.
