Plant extract composition with multi-target scalp oil control and dandruff removal effects, preparation method of plant extract composition and scalp care composition

Abstract

The invention discloses a plant extract composition with multi-target scalp oil control and dandruff removal effects, a preparation method of the plant extract composition and a scalp care composition. The plant extract composition comprises the following components in percentage by mass: 20 to 40 percent of camellia seed extract, 15 to 25 percent of tea bran polysaccharide, 10 to 30 percent of citrus peel extract, 10 to 30 percent of folium eucalypti extract and 1 to 20 percent of radix sophorae flavescentis extract. The multi-target oil control and dandruff removing purposes are achieved infour different ways (inhibition of microbial lipase, inhibition of malassezia beta-carbonic anhydrase, inhibition of 5[alpha]-reductase in scalp cells and inhibition of propionibacterium acnes), and the research shows that compared to a single-target component, the multi-target compositions have characteristics of having the synergistic effect and being capable of remarkably improving the oil control and dandruff removal effects.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a plant extract composition with multi-target scalp oil control and anti-dandruff effects, a preparation method thereof and a scalp care composition. Background technique [0002] The oil control and anti-dandruff functions of hair products are one of the important demands of consumers. In some people, the scalp sebum secretion is too strong, which affects the beauty of the hair. The strong sebum secretion will also lead to the excessive proliferation of microorganisms such as Malassezia and Propionibacterium acnes on the scalp. These microorganisms not only cause dandruff, but also decompose sebum to produce free fatty acids and other metabolites, which cause inflammation in the scalp, causing problems such as itching and sensitivity of the scalp, further stimulating the imbalance of sebaceous gland secretion, aggravating symptoms such as dandruff, and producing se...

Problems solved by technology

There are also many literature reports and published technologies that have developed antibacterial agents based on various plant extracts, but they often have the problem of low antibacterial activity and cannot replace synthetic anti-dandruff agents

[0004] In the prior art, oil control often uses some organic acid components (such as salicylic acid, fruit acid, lactic acid) to peel off the cuticle of the scalp, dredge the pores, and avoid the accumulation of oil in the pores to cause the imbalance of sebum secretion, but the acid components have no effect on the scalp. Strong irritation, not suitable for people with very sensitive scalp
