The application discloses a dandruff-removing composition for men with sensitive skin and application, and relates to the technical field of washing and protecting products.The application provides a dandruff-removing composition, which comprises the following components in parts by weight: Picea abies leaf extract 0.5-5 parts, Hypericum perforatum extract 0.1-2 parts, Salvia miltiorrhiza extract 0.1-2 parts and Olea europaea leaf extract 0.5-5 parts; the Salvia miltiorrhiza extract is a mixture of Salvia miltiorrhiza root extract and Salvia miltiorrhiza leaf extract.The composition prepared by the application can repair the scalp homeostasis from three aspects of fungus proliferation inhibition, sebum secretion regulation and barrier function repair, so that the effect of better controlling oil and reducing dandruff is achieved.

The utility model refers to a cosmetic cream containing extract of Hypericum perforatum (St. John's wort) and finds application in the cosmetic industry, skin care. The cream possesses the beneficial properties of Hypericum perforatum, such as anti-inflammatory, antibacterial, antimicrobial, antioxidant action, moisturizes and softens the skin, resulting in an exceptionally good nourishing, regenerating and protective effect on the skin, without causing irritation or skin rashes.

The invention relates to a multi-effect skin conditioning composition containing medicinal phellinus igniarius and application of the multi-effect skin conditioning composition, and belongs to the technical field of cosmetics. The multi-effect skin conditioning composition is prepared from active ingredients from medicinal phellinus igniarius, a hyperforin perforatum extract, a calendula extract and epigallocatechin gallate glucoside. According to the multi-effect skin conditioning composition, sebum secretion is inhibited through the active ingredient from the phellinus igniarius, the hyperforin perforatum extract has the effects of resisting inflammation and bacteria, the calendula extract has the effects of controlling oil and relieving, and epigallocatechin gallic acid glucoside has the strong effect of resisting oxidation, so that the skin permeability of the composition is remarkably improved; therefore, multiple skin conditioning effects of controlling oil, removing acnes, brightening, removing yellowness, soothing and the like are achieved, and the cream is mild and non-irritant and is suitable for people with sensitive skin to use.

The invention discloses a hypericum perforatum extract insecticide for preventing and treating plutella xylostella and application of the hypericum perforatum extract insecticide, and belongs to the technical field of agriculture. Firstly, a hypericum perforatum ethanol crude extract is prepared and extracted with ethyl acetate to obtain an ethyl acetate extraction fraction with the effect of preventing and treating plutella xylostella; furthermore, on the basis of the biological affinity effect of the acetylcholin esterase, the trypsin and small molecule ligands in the extraction fractions of the ethyl acetate, insecticidal active compounds are screened, and the screened multiple active components have potential acetylcholin esterase and trypsin multi-target inhibitory activity. Animal experiment results show that the botanical insecticide prepared by taking luteolin-7-O-glucoside, quercetin or ethyl acetate extraction fractions as main functional components has an excellent plutella xylostella prevention and treatment effect, is environment-friendly and does not generate secondary pollution. The invention provides an important strategy for the development of biopesticides taking acetylcholin esterase and trypsin as multiple targets.

This invention discloses a cleaning, antibacterial, and anti-inflammatory composition and its preparation method, specifically belonging to the field of daily cleaning and care. The composition comprises the following components in parts by weight: 10-18 parts surfactant, 3-5 parts plant extract, and the remainder being excipients and solvent. The surfactant is an amino acid-type surfactant, cocamidopropyl betaine, and cocamidomethyl MEA in a mass ratio of 10:(0.5-2):(2-3). The plant extract is Rubia cordifolia extract, St. John's wort extract, and Cyperus rotundus extract in a mass ratio of 1:(4-5):(1-3). The plant extract provided by this invention exhibits a significant synergistic effect in antibacterial and anti-inflammatory properties, effectively improving the overall antibacterial, antimicrobial, and anti-inflammatory effects of the formula. This invention also found that when potassium cocoyl glycinate, cocamidopropyl betaine, and cocamidomethyl MEA are used in a specific ratio, they can effectively enhance the detergency of the formula.
