TABLE 3 Table 3

The liquid hair conditioner prepared by the formula provided by the application has low viscosity, shows good semitransparent galacto-makeup, can be better combed on hair when being acted 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 fresh texture, is coated on hair, is quickly absorbed, and can deeply care the injured hair after ironing and dyeing.

From comparison of the test data of example 1 with comparative examples 1-3 in Table 3, the conditioner of example 1 has a lower viscosity; the method has the advantages that the method keeps good form under the conditions of high temperature, low temperature and centrifugation, and is less influenced; the comb-like hair conditioner has obvious effect of improving the comb property of the hair when acting on the hair. The properties of the product obtained in example 1 are significantly better than those of comparative examples 1-3. The method is favorable for improving the compatibility problem of the ammonia-end polydimethylsiloxane in the whole system under the common matching of the ammonia-end polydimethylsiloxane, the polyglycerol-10 and the polyglycerol-10 laurate in a specific proportion, fully plays the role and ensures that the whole system is stable for a long time. Furthermore, by combining the detection data of comparative example 4, the three components must be matched in a specific proportion to achieve good effect; the stability of the product prepared in a specific ratio is poor.

In addition, as is clear from comparison of the test data of example 1 and comparative example 5, various raw materials are required 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 sufficiently mixed, and the effect is greatly affected.

As can be seen from comparison of the test data of examples 1, 4-5 and example 6 in Table 3, the effect of examples 1, 4-5 on hair combability is more obvious than that of example 6, and it is demonstrated that further limiting the ratio of the amino-terminal polydimethylsiloxane, the polyglycerol-10 and the polyglycerol-10 laurate is beneficial to further improving the compatibility of the amino-terminal polydimethylsiloxane and other raw materials in the system, thereby further improving the hair care effect of the liquid hair conditioner.

From comparison of the test data of examples 1 and 7 and example 8 in Table 3, examples 1 and 7 have better comb properties than example 8. The application ratio of polyethylene glycol-160M and polyester-7 is further limited, which is favorable for improving the maintenance of the liquid hair conditioner on hair and leading the hair to be softer and smoother.

As can be seen from comparison of the test results of example 1 and examples 9 to 10 in example 3, example 1 can achieve lower viscosity within a certain range, and can provide a light, thin and fresh feeling in use while maintaining good combability. The selection and special matching of the supplementary emulsifying agent are shown to have influence on the compatible effect of the ammonia-end polydimethylsiloxane in the liquid hair conditioner in the system.

The present embodiment is only for explanation of the present application and is not to be construed as limiting the present application, and modifications to the present embodiment, which may not creatively contribute to the present application as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present application.
