Description

  The present invention relates to a shampoo composition having good transparency stability of appearance and feeling at the time of hair rinse.

  A shampoo composition containing a cationized polymer can be made into a conditioning type that feels like when washing hair or rinsing and has a good texture after drying by combining it with a specific anionic surfactant (patent documents 1 to 6). 3). The reason is that a complex composed of a specific anionic surfactant and a cationized polymer is reduced in water solubility in the process of diluting the shampoo composition with water at the time of hair washing and rinsing. Depending on the conditions, it is known that the complex precipitates and the effects of the precipitate produce the various effects described above. Therefore, it is also known that the feel and feel change depending on the composition of the complex.

  On the other hand, in the shampoo composition having a transparent appearance, when it is attempted to sufficiently ensure the stability of the appearance transparency, even when the cationized polymer is blended, no precipitate during hair washing or rinsing occurs or occurs. However, since the precipitation amount does not reach a sufficient amount, there is a problem that the feel etc. can not be made good at the time of hair washing and rinsing.

  Shampoo compositions were prepared according to a conventional method in Examples 1 to 5 and Comparative Examples 1 to 4 shown in Table 1.

Evaluation of Appearance Stability of Composition With respect to “appearance of composition”, the state of appearance when the prepared composition was thermostated at 25 ° C. was visually judged. The prepared composition was filled in a colorless and transparent cylindrical glass bottle having a volume of about 100 ml, sealed, and thermostated at 25 ° C. using a water bath. After the temperature became constant, the glass bottle was withdrawn from the water bath, the water adhering to the bottle was wiped off, and then visually observed from the side of the bottle. The case where some foreign matter, layer separation, or cloudiness was observed was regarded as x, and the others were made o. The obtained results are shown in Table 1.

Evaluation of the appearance upon dilution of the composition With regard to the “appearance on dilution” of the composition, after accurately weighing the composition at about 40 ° C. into a beaker, using ion exchange water at a liquid temperature of about 40 ° C. The composition weighed in a beaker was diluted, and the permeability was measured immediately after dilution. The dilution factor was measured at two points of about 100 and 200 times in mass conversion. The transmittance was measured using a double beam spectrophotometer, using a quartz cell, at a wavelength of 420 nm. As a target, ion exchange water was used. In the evaluation, the case where the permeability was 50% or less at any dilution factor was evaluated as ○, and the others were evaluated as x. The test was not performed for Comparative Example 2. The obtained results are shown in Table 1. In addition, when the permeability which is the above-mentioned x evaluation exceeds 50%, finger passing is bad at the time of hair washing and rinse, or it feels a squeaky feeling strongly, but when the permeability which is ○ evaluation is 50% or less, It has been confirmed that excellent hair feel can be obtained during hair washing and rinsing with male short hair.
