Technical Field

The invention relates to the technical field of whitening essence, in particular to rose whitening essence and a preparation method thereof.

Background

Roses (Rose rugosa Thumb.) are perennial evergreen or deciduous shrubs of the genus rosa of the family rosaceae and are widely grown worldwide. The roses have the functions of eating and health care, and are officially approved by the state as new resource food in 2010. Modern medicine shows that roses contain more than 300 chemical components, and the roses contain flavonoid compounds which have antioxidant activity and can reduce and eliminate free radicals. The plant flavonoid compound not only can eliminate free radicals in human bodies, but also can inhibit the generation of free radicals, has the effects of preventing aging, cardiovascular diseases, cancers and the like, is an effective antioxidant, and is widely applied to the industries of foods, medical health products, cosmetics and the like. Text of materia medica (text of materia medica) Zhongdao: "Rose flower, clear but not turbid, and not fierce, liver softening and stomach awaking, qi-flowing and blood circulation promoting, and dredging and suffocating without the disadvantage of pungent, warm and hard dryness, among the qi-pushing-off and medicine-dividing, it is most quick and most tame, fragrant, so there is no way to match. The rose contains more than 300 chemical components, such as aromatic alcohol, aldehyde, fatty acid, phenol and oil and fat containing essence, and the rose product is usually eaten to soften liver and wake stomach, relax qi and activate blood, maintain beauty and keep young and refresh people. The flowers and roots of the rose can be used as medicine, has the functions of regulating qi, promoting blood circulation, astringing and the like, and is mainly used for treating irregular menstruation, traumatic injury, liver qi and stomach pain, breast swelling and pain and other symptoms. The rose pulp can be made into jam, has special flavor, contains abundant vitamin C and vitamin P, and can be used for preventing acute and chronic infectious diseases, coronary heart disease, liver disease, carcinogen generation and metastasis, etc. The rose essential oil (called rose dew) extracted from rose petal by distillation method can also improve skin texture, and promote blood circulation and metabolism. The current utilization of roses has the problems of low acquisition rate, insufficient activity maintenance of effective components and the like during filter pressing.

The haematochrome (14d) ═ 58.22E.U., the haematochrome (28d) ═ 52.02E.U., the L value (14d) ═ 59.73, the L value (28d) ═ 65.42, the flavone ═ 728.6mg/g, and the DPPH free radical scavenging rate (96.8%) of example 1 (using litsea cubeba oil or lemongrass oil as the penetration enhancer), comparative examples 1-3 (using peppermint oil and/or litsea cubeba oil and lemongrass oil as the penetration enhancer), comparative example 4 (without the penetration enhancer) the haematochrome (14d) ═ 59.89-68.11E.U., the haematochrome (28d) ═ 52.86-57.99E.U., the L value (14d) ═ 53.40-57.62, L value (28d) ═ 60.51.68, and L value (3519.64.82.0-36709), and the DPPH free radical scavenging rate (96.8%) of example 2-3 (using litsea cubeba oil and lemongrass oil as the penetration enhancer), this is because: the litsea cubeba oil and the lemongrass oil are rich in solvents with active chemical properties, such as alpha-lupinene, alpha-pinene and the like, can effectively promote the rose total flavonoids to seep out of cells of the rose, and improve the collection rate of the filtrate obtained by medium-pressure filtration of the rose soak solution; when the rose extract and the rose flavone are compounded for use, the rose total flavone can be promoted to exude, and simultaneously, the antioxidant protection effect is achieved, and the rose extract with higher rose total flavone content and stronger active ingredient activity can be obtained; the peppermint oil contains more menthol, menthyl acetate and other components, and the effect of improving the collection rate of the total rose flavone obtained from the rose soaked substance is not as good as that of litsea cubeba oil and lemongrass oil. The rose extract contains a large amount of rose total flavonoids which are active ingredients with various beautifying effects of removing free radicals, resisting inflammation, resisting oxidation, removing yellow, brightening, resisting wrinkles, fading spots and the like, can improve the skin state after long-term use, and presents tender, white and bright water. The active ingredients of the vetiver iris root extract, the salvia miltiorrhiza bunge extract, the sudan cola seed extract, the squalane, the trehalose, the linoleic acid, the polydimethylsiloxane and the like can effectively remove free radicals, improve the immunity of the skin, reduce inflammation and sensitivity, reduce the content of red pigment and enable the integral appearance of the skin to be transparent, bright, white and shiny. The active antioxidant components such as total flavonoids in the rose extract prepared by the specific method can promote the metabolism of the generated melanin, has stronger inhibition effect on tyrosinase, simultaneously acts at the source and the route of the melanin, further reduces the content of the melanin in the skin, and further improves the whiteness and the brightness of the skin.
