Description

technical field [0001] The invention belongs to the technical field of shampoos, and relates to an antibacterial, anti-dandruff, anti-itch conditioning shampoo containing organic silicon quaternary ammonium salt. Background technique [0002] Conditioning shampoo is a "two-in-one" shampoo that has conditioning functions such as softening and moisturizing and washing away dirt on the hair and scalp. So far, most shampoos at home and abroad fall into this category. However, the surface of hair and scalp is rich in nutrients such as oil and protein, which are easy to breed bacteria and fungi. There is a bacterium called Malassezia, which is the main bacterium that produces dandruff and makes the scalp itchy. There are also some fungi that can easily make the scalp itchy. Hair water is a much-needed product in the market. But there are not many varieties of this type of multifunctional shampoo on the market at present, and there are some problems in all of them.

AI Technical Summary

Problems solved by technology

Some have poor antibacterial and anti-dandruff effects; some have insufficient smoothing and conditioning functions

[0003] There are five types of anti-dandruff and anti-itch agents commonly used in the market: the first is zinc pyrithione, referred to as "ZPT", which can effectively inhibit and kill the bacteria Malassezia that causes dandruff, but it is insoluble in water , is a solid powder, not easy to disperse in shampoo, and the amount added is large, it must reach about 2% of the total amount of shampoo to have a good effect. In addition, it has a destructive effect on the growth environment of aquatic organisms

The second is piroctone ethanolamine salt, which has bactericidal and antioxidant effects. Its advantage is that it is mild and irritating, and is environmentally friendly. The disadvantage is that it is insoluble in water and soluble in organic solvents and surfactants, but it is easily destroyed. Washed off with water, it is not easy to adhere to the hair and scalp, so the antibacterial and anti-dandruff effect is limited, and the raw material of shampoo has high requirements on water quality, it is easy to turn yellow when encountering metal ions, and the light stability is also poor

The third is ketoconazole, which is a drug with good antibacterial effect, but its disadvantage is that it is very irritating to the eyes and skin, so it has been banned from use

The fourth is Climbazol—climbazol, which has a broad-spectrum bactericidal effect, but the anti-dandruff effect is average, and must be used in combination with "ZPT". As mentioned earlier, "ZPT" is not water-soluble and harmful to aquatic organisms.

In addition, there are salicylic acid, selenium sulfide, boric acid, borax, etc., all of which have certain anti-dandruff and antipruritic effects, among which selenium sulfide is more toxic; salicylic acid is slightly soluble in water; Poor compatibility of ingredients

[0004] In addition, many Chinese herbal medicine anti-dandruff and anti-itch shampoo patents have been published in China, but there are many kinds of Chinese herbal medicines as raw materials and limited resources
