Detailed Description
The invention discloses a body care product composition with a whitening effect. The main whitening functional components of the body care product composition comprise: olive fruit extract, bletilla striata root extract, papain and ginkgo leaf extract, and has the effects of long-acting whitening and the like.
(1) Olea europaea extract
The Olea europaea is also called Olea europaea and Olea europaea, is evergreen arbor of Oleaceae, olea, and is native in China in the Zhonghai and coastal regions. The olive is rich in various proteins, carbohydrates, 17 amino acids, fats, vitamin C and minerals such as calcium, phosphorus, iron and the like required by human bodies, wherein the content of the vitamin C is 10 times that of the apple and 5 times that of the pear and the peach. It also has high calcium content and is easy to be absorbed by human body.
The cell culture method proves that the olive extract has strong activation effect on macrophage activity, one effect of the macrophage in the cortex is to phagocytize melanin, and the inhibition effect on the activity of B-16 melanocyte is combined, so the olive extract has whitening effect on the skin.
(2) Bletilla striata root extract
Bletilla striata is a perennial herb of the orchid family, which grows in hillside grassy bushes, forests and valley shady and wet places. The method is widely distributed in China, has rich resources, and mainly produces Guizhou provinces, sichuan provinces, hunan provinces and the like. The cosmetic is prepared from dried tuber of rhizoma Bletillae, or fresh rhizoma Bletillae and its tuber. After the bletilla striata rhizome extract is added into cosmetics, the bletilla striata rhizome extract can supplement skin nutrition, eliminate excessive free radicals in the body, delay skin aging, and avoid dull complexion caused by skin wrinkles due to oxidation of protein in the skin and loss of a supporting structure of the skin.
(3) Papain
Is a proteolytic enzyme, naturally occurring in papaya, often referred to as "plant protease". The main effects of the papain are cutin removal, dead skin removal on the surface of the skin, old cutin accumulated on the surface of the skin for a long time is removed, and the skin blackening and yellowing caused by long-time accumulation of pigment are avoided.
(4) Ginkgo leaf extract
Ginkgo is a plant with high medicinal value, and the ginkgo tree is one of the ancient tree species in China. The flavone component, manganese, molybdenum and other trace elements contained in the ginkgo leaves can also prevent the formation and deposition of pigments in the dermis, so as to achieve the effects of whitening the skin and preventing and treating pigment patches. The flavonol, amino acid, etc. can also effectively prevent the generation of wrinkles. After the whitening cream is applied to skin care products, the long-acting whitening can be effectively performed on the skin.
