Comparative example 1

Commercially available OSD bath oil was selected.

Comparative example 2

Commercial QY body washes were selected.

Comparative example 3

Blank control.

1. And (5) testing water loss.

The water loss test is carried out on the bath cream and the comparative example, the test conditions comprise an instrument and equipment, a percutaneous water diversion loss instrument, the temperature of 20-22 ℃, the humidity of 40-60% rh and the number of volunteers of 15 persons, the test method comprises the steps of cleaning the test part, standing for 20min between the tests, collecting basic data, and distributing samples for the volunteers after the basic data collection is completed. Volunteers required the use of body wash on the inside of the right forearm, no product on the inside of the left forearm as a blank, commercially available OSD body wash as comparative example 1, and commercially available QY body wash as comparative example 2. The test period of the moisturizing efficacy is 1h after use, and data on the inner sides of the left and right forearms are collected at the time point of returning to a laboratory. Note that volunteers did not touch the test site as much as possible during the test, and that other products of the same efficacy could not be used.

TABLE 1 volunteer basic information

Table 2 example 3 results of a body wash percutaneous moisture loss test:

Note that a larger transcutaneous water loss value represents a poorer moisturizing ability, a smaller transcutaneous water loss value represents a better moisturizing ability, "/" represents no relevant data here, test results were analyzed using a t-test for significance: "x" (P < 0.01); "(0.01. Ltoreq. P < 0.05);" ++ "(0.05. Ltoreq. P < 0.1);" - "(P. Gtoreq.0.1), n=6.

Comparing fig. 4 and 5, the average value of the percutaneous moisture loss was 9.47 as measured from the initial value of the left forearm area (blank) and 10.32 as measured from the right forearm area before using the body wash. After 1H product use, the average of the skin moisture loss was 8.75 in the left forearm area (blank) and decreased by 0.72, while the average of the skin moisture loss was 8.10 in the right forearm area (using body wash) and decreased by 2.22.

Conclusion volunteers measured a decrease in the average value of the percutaneous water loss from 10.32 to 8.10 at the product site of use after 1h of application of the body wash, with a rate of change of-21.5% higher than that of the left forearm area (blank) (-7.6%). Meanwhile, the result of P <0.01 is obtained by performing a significant difference analysis (T test) on the change value data of the percutaneous water loss after 1h use, which shows that the bath foam plays a role in promoting skin moisturizing relative to a blank control after 1h use.

Table 3 shows the percutaneous moisture loss test conditions of each of the examples and comparative examples

By reducing the percutaneous water loss value, the percutaneous water loss can be effectively reduced, so that the water locking capacity of the skin is enhanced. From the above performance test results, it is clear that in examples 1 to 5, example 3 reduced the percutaneous water loss value most, and the water-locking ability was stronger and the moisturizing performance was better. In contrast to the examples, the comparative examples are significantly inferior to the examples in terms of the respective performance tests due to the differences in the composition of the respective components and the production process, and the above experimental results further demonstrate the importance of the technical solutions defined in the present invention for the technical effects thereof.

2. Foam testing.

2G of the bath products of example 3, comparative example 1 and comparative example 2 were placed in a bubbler with 5g of purified water, and under bubbling 50, the comparative foam particle size and foam density were observed by a polarizing microscope.

As shown in FIG. 1, the foam form of the bath foam of example 3, the foam form of the OSD bath oil of comparative example 1, and the foam form of the QY bath foam of comparative example 2, if 3, the foam form of the bath foam of the invention has small particle size, small density and good foam effect.

While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the present invention.
