Description

  The present invention relates to a cleaning material. More specifically, in washing skin and hair, it has excellent foaming properties, fast foaming properties (fast foaming), and foam persistence (foaming properties), as well as a creamy quality and excellent formulation stability. Regarding fees.

  For skin and hair cleansing products, high foaming properties (foam amount), fast foaming properties (fast foaming), foam persistence (foam stickiness), and foam creamy are very important. Is an element. In addition, it must be avoided that the original characteristics are not exhibited due to deterioration of quality over time during use or storage, deterioration of performance, and generation of odor.

  Conventionally, hydroxyalkyl ether carboxylates have been known as highly foaming anionic surfactants (see, for example, Patent Document 1). This hydroxyalkyl ether carboxylate is excellent in foaming property and fast foaming property, but is not always satisfactory in terms of foam sustainability and foam creaminess.

  On the other hand, there has been proposed a cosmetic composition for cleaning that uses a hydroxy ether carboxylate and a cationic polymer in combination to improve ease of loosening, smoothness and flexibility of hair (for example, Patent Documents 2 to 2). 3). The combined use of a hydroxy ether carboxylate and a cationic polymer improves the foam persistence during use and makes the foam quality creamy. However, when a cationic polymer is blended, there is a problem that it is inferior in rapid foaming property. Also, cationized polymers often produce amine odors over time. This odor is a very disgusting odor and has been a problem in preparing a stable formulation.

  Under such circumstances, there is a demand for a cleaning agent that is excellent in terms of high foaming property, fast foaming property (foaming speed), foam persistence (foam stickiness), foamy creaminess, and stability over time. It was done.
