preparation example Construction

[0052] According to a first aspect of the present invention, there is provided a method for preparing hibiscus leaf extract, comprising the following steps:

[0053] S1. Hibiscus leaf powder is provided, and the mixed solution of hibiscus leaf powder and solvent is subjected to low-temperature and high-pressure homogenization;

[0054] S2. Concentrating the filtrate obtained after ultrasonic extraction of the mixture obtained by the low temperature and high pressure homogeneous treatment to obtain a concentrated suspension;

[0055] S3. purifying the concentrated suspension through a polyamide resin to obtain an eluate;

[0056] S4. Decolorizing and separating the eluent to obtain hibiscus leaf extract.

[0057] Specifically, hibiscus leaves are the leaves of Hibiscus hibiscus in Malvaceae, which is a traditional Chinese medicine, and its main components are flavonoids and sterols.

[0058] Hibiscus leaf powder is usually a powdery product obtained by crushing hibiscus leave...

Embodiment approach

[0123] As a preferred embodiment of the present invention, the antiseptic composition comprises the following raw materials in mass fraction: 2-8% of hibiscus leaf extract, 30-60% of polyol, 5-15% of solubilizer, and water to make up the remaining quantity;

[0124] Preferably, the antiseptic composition is made of the following raw materials in mass fraction: Hibiscus hibiscus leaf extract 2.5-8%, polyol 35-55%, solubilizer 5-13%, and water to make up the balance.

[0125] By further limiting the dosage of each raw material of the antiseptic composition, the antiseptic, antibacterial and anti-oxidation effects of the antiseptic composition are more significant, and at the same time, the irritation to the skin is smaller, and the safety is further improved.

[0126] As a preferred embodiment of the present invention, the polyhydric alcohol includes one or a combination of at least two of ethylhexylglycerin, caprylyl glycol, 1,2-pentanediol or 1,2-hexanediol.

[0127] Ethylhex...

Embodiment 1

[0146] The present embodiment provides a kind of preparation method of hibiscus leaf extract, comprising the following steps:

[0147] (1) removing impurities from the dried hibiscus leaves, and pulverizing them with a plant pulverizer, and crossing a 50-mesh stainless steel mesh sieve to obtain hibiscus leaf powder;

[0148] Add hibiscus leaves to 80% ethanol aqueous solution, pretreat it with a low temperature and high pressure homogenizer, the homogenization temperature is 4°C, the homogenization pressure is 5.5MPa, and the homogenization time is 30s;

[0149] (2) Extract the mixture obtained by homogeneous treatment at low temperature and high pressure using ultrasonic-assisted extraction method, ultrasonic power 304W, solid-liquid ratio 1:30, extraction temperature 35°C, extraction time 0.5h, after extraction, suction filter, and collect the filtrate;

[0150] The obtained filtrate was concentrated under reduced pressure to 1 / 6 of the original volume to obtain a concentra...

Abstract

The invention provides a cotton rose leaf and a preparation method thereof, an anti-corrosion composition and a preparation method thereof and a cosmetic composition, and relates to the technical field of cosmetic corrosion prevention. According to the preparation method of the cotton rose leaf extractive, through combination of low temperature and high pressure homogenization treatment, ultrasonic extraction, polyamide resin purification and decolorization, the advantages of high extraction ratio and high extraction speed are achieved. The cotton rose leaf extractive produced by the preparation method is high in flavonoid purity, light in color, high in stability and excellent in security. The invention further provides an anti-corrosion composition. The anti-corrosion composition comprises the cotton rose leaf extractive, polybasic alcohol, a solubilizer, water and the like. The synergistic effect is achieved among raw materials, and therefore the anti-corrosion composition has a significant bacteriostatic effect, a wide bacteriostasis spectrum, stable effect, little thrill and high security. Remarkable antioxidant efficacy is achieved meanwhile. The invention further provides acosmetic composition. The cosmetic composition comprises the cotton rose leaf extractive and the anti-corrosion composition.

Description

technical field [0001] The invention relates to the technical field of cosmetic antisepsis, in particular to Hibiscus hibiscus leaf extract and a preparation method thereof, an antiseptic composition and a preparation method thereof, and a cosmetic composition. Background technique [0002] Preservatives are a class of additives that prevent the growth of microorganisms and prevent product spoilage. In cosmetics, the addition of preservatives can avoid product deterioration, odor, and spoilage caused by microbial activities in cosmetics, prolong the shelf life of products, and prevent consumers from having adverse effects due to the use of cosmetics contaminated by microorganisms. At present, my country's "Safety and Technical Specifications for Cosmetics" (2015 Edition) stipulates 51 preservatives, among which the widely used preservatives mainly include parabens, formaldehyde releasers, benzyl alcohol and its derivatives, methyl iso Thiazolone, phenoxyethanol, etc., there ...
