From Table 1, from the comparison between Example 1 and Comparative Example 1, the cleaning composition of Example 1 using solid fat having an average particle size of 327 nm used solid fat having an average particle size of 11 μm. It can be seen that the amount of adsorption of silicone remaining on the hair is 1.4 times greater than that of Comparative Example 1.
Similarly, from the comparison between Example 2 and Comparative Example 2, the cleaning composition of Example 2 using solid fat having an average particle diameter of 327 nm is compared using solid fat having an average particle diameter of 5 μm. Compared to Example 2, it can be seen that the amount of silicone adsorbed on the hair is 1.5 times greater.
From a comparison between Examples 1 and 2, it can be seen that Example 2, which uses cationized guar gum, has about 7 times more adsorption of silicone remaining on the hair than Example 1, which uses cationized cellulose. .

From the comparison between Example 1 and Comparative Example 3, Example 2 in which the average particle size of silicone is 300 nm shows that the amount of silicone adsorbed on the hair is 2 than in Comparative Example 3 in which the average particle size of silicone is 20 nm. .5 times more.
From a comparison between Example 2 and Comparative Example 4, Example 2 in which the average particle size of silicone is 300 nm shows that the amount of silicone adsorbed on the hair is 7 compared to Comparative Example 4 in which the average particle size of silicone is 20 nm. You can see that it is twice as many.
From Comparative Example 5, when no cationic polymer is used, almost no silicone remains in the hair.
From a comparison between Example 3 and Comparative Example 6 in Table 2, in Example 3, two kinds of solid fats having an average particle diameter of 121 nm and 11 μm were added by adding a small amount of solid fat having an average particle diameter of 121 nm. Thus, it is understood that the pearl gloss is excellent and the amount of adsorption of the silicone remaining on the hair is large.
From Examples 3-5, it turns out that the adsorption amount of the silicone which remain | survives in hair increases proportionally with the increase in the solid fat whose average particle diameter is 121 nm.
