Description

Itching-relieving and relaxing bath lotion and preparation method thereof
Technical Field
The invention relates to the technical field of daily necessities, in particular to itching-relieving and relaxing shower gel and a preparation method thereof.
Background
The bath lotion is a liquid cleaning agent used during bath, is convenient to use and has good cleaning effect, and is an indispensable cleaning daily product in the daily life of modern people. In addition, as the life pursuit of people is continuously improved, the functional pursuit of people on the bath foam is higher, and the bath foam is expected to bring more and better nursing effects to human skin.
In the environment where humans live, microorganisms such as bacteria and dust mites are ubiquitous, and human skin serves as a barrier between the human body and the environment, and is in struggle with these microorganisms at all times. In the process of invading human skin by microorganisms such as bacteria and dust mites, the immune system of the human skin can generate stress, prevent the continuous invading, and generate irritation symptoms such as itching, stinging and the like. At present, most of bath lotions on the market only have the effect of cleaning the surface of human skin so as to remove microorganisms such as bacteria infected on the human skin, and the like, have no relieving effect on symptoms such as itching, stinging and the like, and cannot meet the new demands of people.
Although the bath lotion with the itching relieving effect is available in the market at present, the bath lotion has the problems of more effective components, high cost, poor cleaning power and the like. The refreshing and itching relieving Chinese herbal medicine bath lotion disclosed in the patent application CN201910832394.X comprises 45wt% of a Chinese medicinal composition, 30wt% of a washing material and 25wt% of water, wherein the Chinese medicinal composition comprises folium nelumbinis, purslane, dandelion, radix sileris, tribulus terrestris, fructus kochiae, paniculate swallowwort root, amur corktree bark, fineleaf schizonepeta herb, peppermint and the like, and the refreshing and itching relieving effects are ensured, but the adding amount of the functional components is too large, the cost is extremely high, and the cleaning power is poor. As disclosed in patent application CN201811235196.7, the bath lotion with mite-removing and itching-relieving functions is added with a large amount of chemical compositions, and is added with various functional components such as radix stemonae, cortex phellodendri, radix sophorae flavescentis, paris polyphylla, scandent hop, herba humifuse euphorbiae herb, herba oxalis, rhizoma arisaematis, chinese lobelia, thistle juice, yellow-opening juice and the like, the cleaning functional components act with a small amount of sodium laureth sulfate and cocamidopropyl betaine, the cost is high, and a large amount of chemical compositions also irritate skin, reduce the effect of the itching-relieving functional components and have poor cleaning power.
Moreover, no itching relieving shower gel based on a compound mixture of gentiana macrophylla extract, clove bud extract and kuh-seng root extract is found in the shower gels on the market at present.
In addition, the bath cream on the market at present mainly comprises soap liquid as a main component. The soap base type bath lotion can well remove skin grease, but has poor use temperature and poor performance, is easy to cause irritation to human skin, causes symptoms such as dryness, water shortage, tightness, itching and the like of the human skin, can not effectively relieve the symptoms such as itching, stinging and the like caused by microorganisms, and can aggravate the occurrence of the symptoms.
