Abstract

The invention provides a black rice extract. The mass content of cyaniding in the black rice extract is 0.5-50%. The invention further provides a method for preparing the black rice extract and the application of the black rice extract to skin care products. The content of active ingredients in the black rice extract is high. Besides whitening, the black rice extract can also well resist aging and keep skin elastic by promoting collagen secretion; the black rice extract can remove free radicals in human cells so as to resist aging, and can be added to skin care products as a composite additive.

Description

technical field [0001] The invention belongs to the field of biochemistry, and relates to an extract, a preparation method thereof, and a cosmetic containing the extract, in particular to a black rice extract, a preparation method thereof, and application in cosmetics. Background technique [0002] Herbal ingredients have been used in cosmetic formulations since time immemorial. With the development of science, there are many new technologies that can be used to treat skin aging. However, natural herbal products still have great attraction and broad market because of their high efficiency and low toxicity. Research has confirmed that more and more herbal chemicals have skin benefits, many extracts and compounds have significant potential to treat skin aging, and their mechanisms have been initially elucidated. For skin aging, the application of natural herbal products is mainly aimed at these goals: repair of extracellular matrix (ECM); anti-oxidative stress of cells; anti...
