Description

[Technical field]

[0001] The present invention relates to a cleaning composition. [Background technology]

[0002] In general, different detergents are used for washing the body and for washing hair. This is because, while both detergents for washing the body and for washing hair require foaming and cleaning power, different performance is required for the feel when used. Specifically, detergents for washing the body are required to rinse quickly and have a refreshing feel by providing a tight feeling, while detergents for washing hair are required to have a smooth feel and be easy to run your fingers through from the time of washing to rinsing and after towel drying. In recent years, with the change in lifestyle, there is a need to wash from head to body in a short time in the morning with a shower or the like, and to easily wash both hair and body with one detergent. For this reason, detergent compositions that show high cleaning performance for both skin and hair and also provide an excellent cleaning sensation have been studied. For example, Patent Document 1 describes that a cleanser composition containing a fatty acid or a salt thereof, an alkyl ether carboxylic acid or a salt thereof, an alkyl sulfuric acid or a salt thereof, and a cationic polymer in specific proportions does not make the skin feel sticky when rinsing after cleaning, has a good stop feeling, and gives a refreshing feeling to the touch, and further, reduces hair squeakiness when rinsing, makes the hair smooth to the touch, is less likely to leave hair unrinsed, and gives a refreshing feeling to the touch after rinsing.

[0003] [Patent Document 1] JP 2020-15676 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, even with the cleansing composition of Patent Document 1, the smoothness of hair during washing is not sufficient, and there is a problem that hair tends to become tangled, particularly in the case of long hair. To provide a detergent composition which can wash both hair and the body at the same time, and when rinsed after washing, gives the body a quick feeling of rest and leaves the skin refreshed after washing, while at the same time makes the hair smooth to the touch and leaves little residue when rinsed, while providing a refreshed feel at the end of rinsing. [Means for solving the problem]

[0005] The present inventors have found that a cleaning composition which solves the above-mentioned problems can be obtained by using a combination of one or more selected from N-acyl neutral amino acids, N-acyltaurines, and salts thereof, and a natural polysaccharide-based cationic polymer having a specific viscosity and degree of cationization.

[0006] The present invention comprises the following components (A) and (B): (A) one or more selected from N-acyl neutral amino acids, N-acyltaurines, and salts thereof; (B) A natural polysaccharide-based cationic polymer having a viscosity of 1% by mass aqueous solution at 25°C of 1000 mPa·s or less and a degree of cationization of 2% or more. The present invention relates to a cleaning composition comprising the above-mentioned compound. Effect of the Invention

[0007] The detergent composition of the present invention does not leave the skin sticky when rinsed after washing, has a good stop feeling, and gives a refreshing feeling. Moreover, hair is prevented from squeaking when rinsed, making it smooth to the touch, and is less likely to leave hair unrinsed.
