Embodiment 1

[0083] A marigold extract, prepared by the following method:

[0084] (1) Add the wanshou fruit powder into the de-ethanol, control the mass ratio of wanshou fruit and ethanol to calculate, that is, mix wanshou fruit: ethanol at 1:20 to obtain a mixed solution;

[0085] The resulting mixed solution was subjected to ultrasonic extraction for 15-30 minutes under ultrasonic conditions with a control temperature of 70°C, a power of 150W, and a frequency of 40kHz, and then filtered with a 0.45 μm microporous membrane;

[0086] (2), the filtrate obtained after filtering step (1) is controlled to carry out vacuum rotary evaporation under the condition of 0.095MPa to obtain the longevity fruit extract concentrated solution, and the obtained longevity fruit extract concentrated solution is controlled at a temperature of - Freeze-drying at 55°C to obtain Longevity Fruit Extract.

[0087] The anti-sensitivity effect of the above-mentioned longevity fruit extract was investigated respect...

Abstract

The invention discloses a papaw extract. A papaw fruit is dried and then crushed into powder, then papaw powder and an ethyl alcohol or methanol solvent are mixed at the proportion of 1:(10-30), ultrasonic extraction is performed at 60-80 DEG C, liquid is filtered by a microfiltration membrane, the filtrate is collected, vacuum rotary evaporation is performed under the condition that the vacuum degree is controlled to be 0.094-0.096 MPa to obtain a papaw extract concentrated solution, and the concentrated solution is subjected to freeze drying to obtain the papaw extract. The papaw extract can serve as an anti-allergic agent and particularly can be applied to skin cosmetics, the mass ratio of the papaw extract to the skin cosmetics is (0.0002-10):100, and the papaw extract is added into the skin cosmetics. The characteristic of simple and feasible preparation process is achieved, the finally obtained skin cosmetics are natural and safe, and the characteristics of aging resistance and the like are achieved while the antiallergic property is ensured.

Description

technical field [0001] The invention belongs to the field of daily chemistry, and relates to a cosmetic, in particular to a marigold fruit extract and its preparation method and its application in skin care cosmetics for sensitive skin. Background technique [0002] Longevity fruit, also known as chicken feet, sweet midnight, etc., is a widely distributed deciduous tree of Rhamnaceae. Its fruit is rich in various functional components such as glucose, polysaccharides, dammarane-type triterpene saponins and calcium fruitate. It is used in boiling fructose, maltose, making beverages and fermenting wine. Ganping with fruit stem has the effect of invigorating the stomach and nourishing blood, can cure rheumatism, and has the effects of hangover, diuresis, blood pressure lowering, blood sugar lowering, and detoxification. [0003] The research results in the field of modern medicine show that the polysaccharides in Longevity Fruit have the effect of scavenging hydroxyl free radi...
