Description

  The present invention relates to a shampoo composition that can effectively remove dirt derived from sebum and hair dressing, is excellent in foam quality at the time of shampooing, and has good smoothness after rinsing and after drying.

  The shampoo is required to have a cleaning effect for removing sebum and hair dressing, as well as a conditioning effect to form fine bubbles to reduce hair damage due to friction and to improve the feel after rinsing and after drying. In recent years, with the diversification of consumer needs for hairstyles, the use of hair styling that contains highly lipophilic oils such as film polymers and waxes has increased, and it is difficult to remove these oils by washing with shampoo. There is a problem. In order to improve the detergency of the shampoo and remove these oils, it is conceivable to add a surfactant at a high concentration. In this case, however, squeaking may occur during rinsing or it may become dry after drying. Therefore, in conventional shampoos, a cationic polymer is blended as a conditioning component, and a coacervation phenomenon in which a complex formed from this, an anionic surfactant, and an amphoteric surfactant precipitates. Of smoothness. Therefore, in the shampoo formulation, it is important to control the production amount and production area of this complex.

  Non-Patent Document 1 describes that the coacervation forming region is expanded by adding an inorganic salt. However, when an inorganic salt is added, there is a problem that the amount of foam decreases or the foam quality deteriorates. there were.

  In view of such a situation, Patent Document 1 includes an ionic surfactant, cationized tara gum, polyoxyethylene (7) coconut oil fatty acid glycerin, and even in a diluted region at the time of rinsing, due to the coacervation phenomenon. Disclosed is a shampoo composition that produces a large amount of a complex, is excellent in fingering properties during rinsing, does not feel dry even after drying, and has a good unity. However, this composition does not have sufficient detergency for a hair styling compounded with a highly lipophilic oil agent, and the foam quality during shampooing is not satisfactory.

Patent Document 2 contains amphoteric surfactant, anionic surfactant, cationic polymer, polyhydric alcohol, polyoxyethylene (7) coconut oil fatty acid glycerin, tetraoleic acid polyoxyethylene (60) sorbit However, a shampoo composition having good foam quality and capable of imparting firmness and stiffness to the washed hair is disclosed. However, this composition has an insufficient feel during shampooing and rinsing, and the cleaning power is not sufficiently satisfactory.
In this way, it is possible to effectively remove hair styling blended with a highly lipophilic oil agent, excellent foam quality at the time of shampooing, good conditioning effect, in other words, smoothness after rinsing and after drying A good shampoo composition has not been developed.

Therefore, detergency, foam quality, and smoothness after drying were not sufficient.

  In Comparative Example 5, since the component (D ′) in which the number of moles of AO added per hydroxyl group m / x in the general formula (1) is less than 5 in the general formula (1) is used instead of the component (D), the foam quality and the conditioning effect Was insufficient. In Comparative Example 6, since the component (D ′) having an esterification rate of less than 40 was used instead of the component (D), the cleaning power was insufficient and the smoothness after drying was not sufficient. In Comparative Example 7, since component (D ′) in which m / x in general formula (1) exceeds 20 is used instead of component (D), the foam quality is excellent, but the cleaning power and conditioning The effect was insufficient.
