Description

Technical Field

[0001] This invention relates to the field of raw materials for shampoo products, and in particular to a dandruff-reducing, anti-itch, oil-controlling, and volumizing composition containing a complex of natural plants. Background Technology

[0002] With social development, people's needs for shampoo products are no longer limited to cleaning. Therefore, existing shampoos usually add functional ingredients such as dandruff-removing, anti-itch, and oil-controlling ingredients to give them more hair care benefits. In order to reduce the potential threats posed by chemically synthesized raw materials, plant extracts have become the main functional ingredients. Although existing shampoos can achieve corresponding effects by adding plant extracts with oil-controlling, soothing, and Malassezia-inhibiting effects, they are simply a matter of stacking multiple functional ingredients without research on their reasonable combination. As a result, the actual dandruff-removing, anti-itch, and oil-controlling effects of these shampoos are relatively average and fail to meet consumer needs. Therefore, there is still room for improvement. Summary of the Invention

Heat to 82°C, stir at 60 rpm for 20 minutes, then cool to 42°C and add 2.288 kg polydimethylsiloxane. Alkyl alcohol, 0.048 kg TEA salt of dodecylbenzenesulfonate, 0.008 kg ethylhexylglycerin, 0.04 kg phenoxyethanol, 0.1232 kg lauryl ether-23, 0.392 kg zinc pyrithione, 0.991 kg sodium chloride, 0.5 kg (daily use) fragrance, 0.144 kg panthenol-hydroxypropyl stearyl dimethyl ammonium chloride, 0.006 kg methylisothiazolinone, 0.024 kg benzyl alcohol, 0.042 kg propylene glycol, 0.08 kg sodium hydroxide, 0.05 kg zinc chloride, and 1 kg of a dandruff-reducing, antipruritic, oil-controlling, and volumizing composition containing complex natural plant extracts were mixed at 60 rpm for 15 minutes, and then discharged to obtain the shampoo to be tested.

[0111] A number of volunteers were recruited and divided into groups of 10. The groups used the test shampoo containing a compound natural plant-based anti-dandruff, anti-itch, oil-controlling, and volumizing composition, which was added to each of the embodiments and comparative examples. The volunteers washed their hair once every two days and used it continuously for 60 times.

[0112] After the first shampoo, each volunteer randomly plucked 10 hairs from the top of their head and measured the diameter of the hair 1-2 cm from the root. This was recorded as the initial hair diameter. After the 60th shampoo, another 10 hairs were randomly plucked from the top of each volunteer's head and the diameter of the hair 1-2 cm from the root was measured. This was recorded as the hair diameter after conditioning. The average of the data from each group was taken.

[0113] The thicker the diameter of the hair, the stronger it is, and the better it can present a fluffy appearance.

[0114] The diameter of a hair was measured using a photoelectric microscope.

[0115] The detailed experimental data for Experiments 1-4 are shown in Table 1.

[0116] Table 1

[0117] According to the data in Table 1, the 5-α reductase inhibition rate, hyaluronidase inhibition rate, and inhibition ring diameter of each embodiment were significantly higher than those of the control ratios. This shows that the combination of camellia seed cake extract, soapberry pericarp extract, sophora flavescens root extract, gentian root extract, arborvitae leaf extract, dictamnus dasycarpus root bark extract, rice bran extract, and tribulus terrestris fruit extract can fully exert the synergistic effect of each active ingredient, making the oil control, itch relief, and dandruff removal effects more significant. In addition, the camellia seed cake extract obtained through a special extraction process has a better effect when combined with other extracts, further enhancing the oil control, itch relief, and dandruff removal effects.

[0118] Meanwhile, after using the shampoo with the added ingredients from the example, the increase in hair diameter after conditioning was more significant compared to the initial hair diameter. This shows that the combination of the ingredients in the example can effectively promote hair follicle repair, making the hair follicles healthier, thereby making the new hair thicker and stronger. In addition, the camellia seed cake extract obtained through a special process has a better effect when combined with other extracts, resulting in a better effect of making the new hair thicker and stronger.
