Washing and massaging ex vivo real human hair bundle with 2ml test object for 1min, and washing in tap water for 1min to avoid hair knotting. Then dried vertically in a room with 30 ℃ and 65% relative humidity for 12h. The carding performance is detected in a room with the temperature of 23 ℃ and the relative humidity of 65 percent, and the maximum carding force and the total carding work of the corresponding detection object are obtained. The reduction (%) of the maximum combing force is recorded in the table.

The results of the tests 1, 3 and 4 are shown in Table 3.

TABLE 3

The liquid hair conditioner prepared by the formula provided by the application has lower viscosity, presents good semitransparent galacto-make-up, can be well combed on hair when being used on the hair, is not easy to remain in the rinsing process, and is convenient to rinse. The liquid hair conditioner has light, thin and refreshing texture, can be quickly absorbed after being coated on hair, and can deeply care the hair after being scalded and dyed.

As can be seen from the comparison of the test data of example 1 and comparative examples 1-3 in Table 3, the conditioner of example 1 has a lower viscosity; the good form is kept under the high temperature, low temperature and centrifugal state, and the influence is small; it can be used for improving hair combing property. The performance of the product prepared in example 1 is clearly better than that of the products of comparative examples 1 to 3. The compatibility problem of the amino-terminated polydimethylsiloxane in the whole system is favorably improved, the function of the amino-terminated polydimethylsiloxane is fully exerted, and the whole system is long-acting and stable under the co-cooperation of the amino-terminated polydimethylsiloxane, the polyglycerol-10 and the polyglycerol-10 laurate in a specific proportion. In addition, the detection data of the comparative example 4 are combined, so that the three components have to be matched in a specific proportion to achieve a good effect; the product prepared in a specific ratio has poor stability.

In addition, as can be seen from comparison of the test data of example 1 and comparative example 5, various raw materials need to be added in a specific step, and if all raw materials are mixed in an unordered manner to prepare the product, the obtained product cannot be mixed sufficiently, and the effect has a great influence.

As can be seen from the comparison of the test data of examples 1, 4-5 and example 6 in Table 3, the effect of examples 1, 4-5 on the combing property of hair is more obvious than that of example 6, which shows that the proportion of the amino-terminated polydimethylsiloxane, the polyglycerol-10 and the polyglycerol-10 laurate is further limited, which is beneficial to further improving the compatibility of the amino-terminated polydimethylsiloxane and other raw materials in the system, thereby further improving the hair care effect of the liquid hair conditioner.

As can be seen from comparison of the test data of examples 1 and 7 and example 8 in Table 3, examples 1 and 7 have better combing properties than example 8. The description further limits the use ratio of the polyethylene glycol-160M and the polyester-7, which is beneficial to improving the hair care of the liquid hair conditioner and ensuring that the hair is softer and smoother.

As is clear from the comparison of the results of the tests of example 1 and examples 9 to 10 in example 3, example 1 can achieve a lower viscosity within a certain range, and can provide a light, thin and refreshing feeling in use while maintaining good combing properties. The selection and special matching of the supplementary emulsifier have an influence on the compatibility effect of the amino-terminal polydimethylsiloxane in the liquid hair conditioner in the system.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
