Problems solved by technology

[0004] At present, the research on the functional components of Camellia plants mainly focuses on camellia seed oil and its traditional pressing process, while the research on camellia leaves is relatively small, especially the natural extracts developed with camellia leaves as raw materials in skin care products. There are very few studies on application research and efficacy testing; at the same time, camellia seed oil products are mainly edible products on the market, and are rarely used as high-end raw materials for cosmetics; the current refining technology of camellia seed oil is difficult to refine into high-grade camellia oil for cosmetics; In addition, the harvest of tea oil seeds is seasonal, the storage conditions are relatively strict, and mildew, rot and oxidation are prone to occur during storage.

Abstract

The invention discloses a camellia azalea composite extract as well as preparation and application thereof in cosmetics. The composite extract comprises the following components in percentage by mass:50-80% of a camellia azalea seed supercritical extract, 10-30% of a camellia azalea leaf supercritical extract and 10-30% of a camellia azalea leaf residue supercritical extract. The composite extract prepared by carrying out supercritical extraction on camellia azalea seeds, carrying out mixing and supercritical extraction on camellia azalea leaves and carrying out enzymolysis and alcohol extraction on camellia azalea leaf residues contains multiple active ingredients such as sitosterol, squalene and alpha-VE and oleic acid with relatively high content, so that the oxidation resistance is better. Cosmetics prepared from the composite composition has better skin barrier restoration effects such as catching moisture, resisting oxidation and improving the skin elasticity.

Description

technical field [0001] The invention relates to the technical field of deep processing of camellia raw materials, in particular to a red camellia compound extract for improving the comprehensive utilization of camellia plants, its preparation and its application in cosmetics. The red camellia combination extract of the present invention has the effects of enhancing the antioxidant capacity of the skin, improving skin elasticity, improving the water-holding ability of the skin and repairing the skin barrier, and can be added to cosmetics as high-end cosmetic functional raw materials. Background technique [0002] Camellia japonica (Camellia japonica L.) is a plant of the genus Camellia in the family Theaceae, which belongs to the woody plant of evergreen broad-leaved forest. Yunnan, Jiangxi, Sichuan and other places. As a natural resource, camellia is rich in flavonoids, polyphenols, VE, oleic acid, squalene, phytosterols and other bioactive components and nutrients such as ...
