Description

  The present invention relates to a cleaning composition, and more particularly to a cleaning composition that is excellent in usability after cleaning of hair and skin.

  Conventionally, anionic surfactants such as alkyl sulfate ester salts, polyoxyethylene alkyl sulfate ester salts, N-acyl amino acid salts and higher fatty acid salts are used in the detergent composition. Anionic surfactants have excellent detergency, but remove not only dirt on the skin and hair but also more sebum components than necessary, creating a feeling of touch and a feeling of tension, and comparing in terms of safety There are drawbacks such as high mechanical irritation and foaming properties but excellent foaming properties.

  Therefore, Patent Document 1 proposes a soap detergent composition in which dimethyl-2-hydroxylaurylbetaine is blended with soap to improve foaming properties in the presence of oil, and Patent Document 2 A detergent composition excellent in foaming and having a good feeling in use, in which an alkyl glyceryl ether sulfonate, a 2-hydroxyalkyl betaine surfactant and an amino acid anionic surfactant are blended at a specific ratio is proposed. A detergent composition with excellent foaming and good usability is proposed, in which alkyl glyceryl ester sulfonate, 2-hydroxyalkyl betaine surfactant, amino acid anionic surfactant and / or soap are blended at a specific ratio. However, these proposals do not provide sufficient foaming properties and good foam quality during cleaning, Will remain is a feeling, not sufficiently satisfactory, such as can not be obtained feeling refreshed.
