Description

The present invention is a hair cleaning agent that has excellent hue stability, fine foam quality during hair washing, produces coacervates even at low concentrations, has good finger passage during rinsing, and maintains good finger passage until after drying. Regarding the composition.

Acylamino acid-based anionic surfactants are used in body and hair cleansing agents as excellent low-irritant surfactants that have a cleansing action without damaging the skin and hair (Patent Documents 1 to 3). ).
Split ends and split ends may occur due to entanglement of hair during washing or rinsing when used as shampoo. In addition, not only when shampoo is used, but also the condition of the hair after drying changes the easiness of entanglement of the hair, and when the hair is in a stiff state, split ends and split ends are likely to occur. Therefore, finger passage is required when rinsing hair, and a smooth finish with good finger passage is required even after drying.
As a known technique for suppressing entanglement of hairs, there is a method of blending an oil component to give the hairs slipperiness. Among them, silicone is excellent in that it suppresses finger passage during rinsing and dryness after drying, and is widely blended in shampoos. On the other hand, in the shampoo containing silicone, there is a problem that silicone may remain on the hair and the effects of hair perm treatment and hair color treatment are impaired. Although silicone-free cleansers have been developed for some hair cleansers, they have the drawback that they do not provide sufficient finger-passability and smooth finish during rinsing.
In order to make up for this drawback, there is known a method of improving finger passage during hair washing and rinsing by utilizing a phenomenon called coacervation. This phenomenon occurs when a specific surfactant and a cationic polymer form a lubricious agglomerate (coacervate) in a diluted state from the time of washing the hair to the time of rinsing, and it becomes insoluble in water and precipitates, and is adsorbed on the hair surface. Shows the effect of improving the finger passage of hair from washing to rinsing. As a technique for improving finger passage during shampoo rinsing using this method, for example, a combination of carboxyethyl cellulose with a sulfate-type surfactant and a cationic polymer such as cationized cellulose or cationized starch (patented). Document 4), a combination of an anionic surfactant, monoalkyl glyceryl ether, and cationized hydroxypropyl cellulose (Patent Document 5) and the like have been proposed. However, depending on the type of surfactant to be mixed, it is difficult to form coacervates, and it is not always possible to improve the squeaky feeling during hair washing and rinsing.
Among them, the anionic surfactant has a core selvate production range that changes depending on the type of counterion, and the triethanolamine salt, which is an organic salt, has a wider dilution concentration range than alkali metal salts such as sodium salt and potassium salt. Produced core selvate in and had better finger passage during rinsing. However, the triethanolamine salt of the anionic surfactant has a problem of being colored when stored at a high temperature.
