Description

  The present invention relates to a foamable aerosol detergent composition that has a good feel during use and a good finish after washing.

  Anionic surfactants are generally used as cleaning components in cleaning compositions such as shampoos because of their excellent detergency. However, because of its high detergency, when used in shampoos and the like, there is a risk of washing away components necessary for hair, scalp and skin along with dirt. Washing away the necessary components for the hair, scalp and skin can cause hair to become squeaky and the scalp and skin to dry after use. Therefore, there is a demand for a detergent composition that does not contain an anionic surfactant and that is suitable as a shampoo that is gentle to hair, scalp, and skin.

  The foamable aerosol cleaning composition differs from a general cleaning composition in that the foam of the cleaning composition is formed by spraying the stock solution in the container. By causing the cleaning composition to foam by spraying, it is possible to eliminate the trouble of foaming the cleaning composition with the scalp and gently wash the hair using the foam from the beginning. For this reason, in a foamable aerosol cleaning composition, the foamability at the time of injection needs to be favorable. It is also necessary to be fully foamed during use so that sufficient foam is maintained. And when using it as a shampoo, the finish after a finger wash and a touch is also suppressed, suppressing the squeak after hair washing.

  Patent Document 1 proposes a foaming cleansing composition that does not contain an anionic surfactant. The document describes at least one amphoteric or zwitterionic interface selected from a) alkylamphoacetals in an aqueous medium to generate a large amount of rigid foam when the consumer stretches it. An active agent, b) at least one nonionic surfactant selected from glycerolated polyethylene glycol esters, c) at least one propellant containing no anionic surfactant and foaming cleansing composition Is described.

[Examples 1-4 , Comparative Examples 1-6 ]
The foamable aerosol cleaning compositions of Examples 1 to 4 were prepared using the stock solutions of stock solutions Nos. 14 to 17 (see Table 1), and the foamability of Comparative Examples 1 to 6 using the stock solutions of Stock Solutions Nos. 8 to 13 An aerosol cleaner composition was prepared. The foamable aerosol detergent composition thus obtained was evaluated for foaming properties during jetting, foaming during hair washing and feel (squeaking) using the methods described above. Table 3 shows the evaluation results of each item.

As shown in Table 3, Comparative Example 5 using the stock solution (12) containing steartrimonium chloride and the stock solution (14-17) containing (A) polyquaternium-4 and (B) polyquaternium-50 were used. All of the foamable aerosol detergent compositions of Examples 1 to 4 were free from squeaks after washing the hair, and good in fingering. From this result, it was found that by using (A) polyquaternium-4, it becomes a cleaning composition that gives good feel to the hair with good fingering after hair washing.

When (B) polyquaternium-50 was used alone, it did not exhibit the touch improvement effect after washing the hair, but when it was used in combination with (A) polyquaternium-4, a high touch improvement effect was achieved (Examples 1 to 4) . 4 ). That is, by using (A) polyquaternium-4 and (B) polyquaternium-50 in combination, a detergent composition that gives good feel to the hair, especially after passing the hair, due to the synergistic feel-improving effect of both. Was found to be obtained.

Moreover, the foamable aerosol cleaning composition of Example 4 had particularly good foaming during use as compared with other Examples. From this result, it was found that if the surfactants (C) to (E) were used as the ratio of the stock solution 17 used in Example 4 , foaming during use was particularly good.

[Examples 1 and 4 ]
The chloride ion concentration in each stock solution used in each foamable aerosol cleaner composition of Examples 1 and 4 was evaluated. Table 4 shows the evaluation results of each item.

The chloride ion concentrations of the stock solutions (stock solutions 14 and 17) used in Examples 1 and 4 were both lower than 500 ppm. Therefore, it can be said that it is preferable to use (A) polyquaternium-4 and (B) polyquaternium-50 as the feel improver from the viewpoint of suppressing the influence of chloride ions on the container.
The chloride ion concentration of the stock solution used in Example 4 was as low as 35 ppm. Thus, by using sodium cocoamphoacetate as (E) imidazoline type betaine, the foaming property at the time of jetting and foaming at the time of shampooing were improved, and the chloride concentration in the stock solution could be made extremely low.

According to the present invention, it is possible to prepare a stock solution suitable as a stock solution for a foamable aerosol cleaning composition that has good foaming properties during jetting and foaming during hair washing.
In addition, according to the present invention, since the chloride ion concentration in the stock solution can be extremely low, in addition to preventing corrosion of the container, sensitive skin in which the influence of chloride ions on the hair, scalp and skin is suppressed as much as possible. It is also useful as a foamable aerosol cleaner composition.
