Comparative example 1

Substantially the same as in example 1, the only difference is that: the thickener acrylic copolymer is replaced by xanthan gum which is also used as a thickener.

Comparative example 2

Substantially the same as in example 1, the only difference is that: the mineral mud kaolin is replaced by titanium dioxide which is the same as the mineral mud.

The components and contents of the above comparative examples 1 to 6 are shown in Table 2 below.

TABLE 2

Comparative examples 1 to 6 were prepared in the same manner as in example 1 except that the other components were used instead of the specified components in Table 1.

Performance testing

(1) Test example 1: high temperature stability test

The high temperature stability test was performed on the cleaning care compositions prepared in examples 1-3 and comparative examples 1-6, and the specific test method is: 100g of the samples of examples 1 to 3 and comparative examples 1 to 6 were taken, respectively, and filled into transparent glass bottles, and then placed in a 45℃incubator for 1 week, and then the appearance change of the samples was visually evaluated. The results obtained are shown in Table 3.

TABLE 3 Table 3

As can be seen from the high temperature stability test of Table 3, under the system of the present invention, examples 1 to 3 and comparative example 2, comparative example 5, in which the thickener acrylic copolymer was added, were each capable of maintaining the viscosity of the system at 45℃and effectively suspending the powder, exhibited excellent high temperature stability, while comparative example 4, in which other synthetic thickeners such as acrylic acid (esters)/C10-30 alkanol acrylate crosslinked polymer was added, and comparative examples 1 and 3, in which conventional natural thickeners such as xanthan gum were added, were each subjected to a problem of high Wen Liaoti viscosity drop resulting in powder settling (see FIG. 1 for details). This demonstrates that the acrylic copolymer thickener is more capable of maintaining the viscosity of the system at high temperatures in high surfactant systems.

Meanwhile, in comparative example 6, which is added with the acrylic acid (ester) copolymer as a thickener but does not contain the amphoteric surfactant lauryl betaine, the phenomenon that the viscosity is reduced and powder cannot be suspended at high temperature (see figure 1 in detail) is also shown, and analysis shows that in the system of the invention, the betaine amphoteric surfactant can generate a synergistic effect with the anionic surfactant in the system to lead the volume of micelles formed by the surfactant in the system to be rapidly increased so as to achieve the effect of effective thickening, and the overall thickening effect is obviously reduced after the betaine amphoteric surfactant is absent.

(2) Test example 2: foam height test

The foam height test was performed on the cleaning and care compositions prepared in examples 1-3 and comparative examples 1-6, and the specific test method was: the cleaning and care product compositions prepared in examples 1-3 and comparative examples 1-6 are respectively prepared into aqueous solution samples with the mass concentration of 0.1%, 30mL are taken in a 100mL measuring cylinder, the mixture is vibrated up and down for 6 times, and the upper edge height of the foam after the vibration is finished, the mixture is kept stand for 5min and the foam is kept stand for 10 min. The results obtained are shown in Table 4.

TABLE 4 Table 4

As can be seen from Table 4, both the foam height and foam stability of examples 1-3 are significantly better than comparative example 3, which does not contain the thickener acrylic copolymer and kaolin powder. The foaming heights of comparative example 1 and comparative example 4 were close to those of examples 1 to 3, but the foam stability was poor and defoaming was fast, which suggests that the natural thickener xanthan gum used in comparative example 1 and the thickener acrylic/C10-30 alkanol acrylate crosslinked polymer used in comparative example 4 could not effectively suspend the kaolin powder in the system, resulting in gradual settling of the powder and rapid defoaming.

The foam stability of comparative example 2 and comparative example 5 was close to that of examples 1-3, but the foaming height was significantly lower than that of examples 1-3, which suggests that the titanium pigment used in comparative example 2 and the perlite used in comparative example 5, while also belonging to natural mineral powders, were not effective in supporting foam, and the effect of improving the overall foam amount was not significant, and analysis was considered that they had no three-dimensional porous structure similar to kaolin, and it was difficult to exert the corresponding effects in the system of the present invention.

Comparative example 6, although having a foam height similar to that of examples 1-3, has poor foam stability and fast defoaming, and analysis shows that the thickening agent acrylic copolymer is added, but the amphoteric surfactant lauryl betaine is not contained, so that the synergistic effect with the anionic surfactant in the system is lost, the viscosity of the material is reduced, the kaolin powder cannot be effectively suspended, and the gradual sedimentation and rapid defoaming of the kaolin powder are caused.

(3) Test example 3: cleaning effect test

The cleaning and child-resistant product was tested on the cleaning and child-resistant compositions prepared in example 1 and comparative examples 1-6, using the following test methods: the test samples were compared for residual child sunscreen on the skin before and after use under UV irradiation. The results obtained are shown in FIG. 2.

The cleaning and hip-care cream was tested on the cleaning and hip-care compositions prepared in example 1 and comparative examples 1-6, and the specific test method was: skin oil content values after each test sample was compared. The results obtained are shown in FIG. 3.

As can be seen from fig. 2 and 3, the products of example 1, comparative example 4, and comparative example 6, in which kaolin was added, had less residual child cream and hip cream on the skin surface and had excellent cleaning effects, as compared with comparative example 2, comparative example 3, and comparative example 5. However, the comparative examples 2 and 3 and the comparative example 5 added with titanium dioxide cannot effectively remove residual child sunscreen cream and hip-protecting cream, which shows that the addition of kaolin in the system of the invention can more effectively adsorb grease, and has more remarkable effect on cleaning child products rich in oily components and sunscreens.

(4) Test example 4: mild test

The composition of the washing and caring product prepared in example 1 was subjected to animal acute skin irritation and acute eye irritation tests, and the results obtained by comprehensive evaluation of the integrated average value of the skin irritation reaction and eye irritation reaction according to the "cosmetic safety technical Specification" are shown in tables 5 and 6.

TABLE 5 test results of acute skin irritation test of test subjects on rabbits

TABLE 6

(30 S flushing)

As can be seen from tables 5 and 6, example 1 showed no irritation to eyes and skin as determined by an average value of 0 for each integral response to acute skin and eye irritation of rabbits.

From this, the cleaning and caring product composition prepared in example 1 has excellent cleaning power, no irritation to eyes and skin of infants, and is a mild cleaning and caring product suitable for daily use of infants.
