2. Comparative experiment of sterilization, dandruff removal and repair

1. Sterilization test

1.1 preparation of Gluconol Red Broth

To a tube that had been autoclaved (121 ℃,2 h) were added 1% glucose, 0.002% phenol red and broth, respectively, 25.00mL each.

1.3 results and analysis

1.3.1 Sterilization of the Natural conditions

The experimental results (table 2) of the bacteria solution cultured under natural conditions show that the phenol indicators in groups I and IV are changed from red to yellow and the color is obviously lightened due to the growth of bacteria and the fermentation of glucose in glucose phenol red broth to produce acid; in group III, the glucitol red broth is slightly lighter in color; group II, the color of the glucose phenol red broth was not substantially changed. The shampoo formula provided by the invention can enhance the obvious sterilization effect of nano sulfur on the mixed bacteria under natural conditions, and the sterilization effect is better than that of common precipitated sulfur.

2. Comparison of the effects of dandruff removal and repair

The hair can be divided into three parts from outside to inside, namely, hair cuticle, hair cortex and hair medulla. The hair cuticle (also called cuticle and cuticle) is formed by overlapping flat cells into a fish scale shape in a staggered way, is the outermost layer structure of hair, and mainly comprises keratin which is composed of a plurality of amino acids. The so-called damage caused by dyeing, perming and straightening hair is the damage of hair cuticle. If the cuticle is damaged, the cuticle scales will be arched. To obtain more visually apparent results, the hair washed with the shampoo to be tested was observed under an electron microscope. If the scale does not arch or slightly arches, the repairing effect is good.

The hair washed with the shampoo to be tested was observed under an electron microscope, and the results are shown in fig. 1 to 4: as can be seen from FIGS. 1 to 4, all of the 3 shampoos had the anti-dandruff effect, but the shampoo of example 3 with nano sulfur showed the best effect, and the scales of the hair were tightly closed after shampooing, and the arched scales were hardly found, and the scales were arranged in order to form a thin film, thereby protecting the hair from the external environment.

Although the embodiments disclosed in the present application are described above, the descriptions are only for the convenience of understanding the present application, and are not intended to limit the present application. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims.
