Abstract

The invention discloses an antioxidant composition applied to cosmetics. The antioxidant composition is prepared from, by weight, 6-10 parts of angelica keiskei extract, 3-5 parts of resveratrol and 1-2 parts of sodium hyaluronate. The invention also provides a preparation method of the angelica keiskei extract in the antioxidant composition. Through improvement of the method, coumarin in the angelica keiskei extract is removed, so product safety is improved. The antioxidant effect of the composition is obviously superior to the antioxidant effect of each single component in the composition, and the composition is high in safety, low in sensitization and suitable for preparation of cosmetics.

Description

technical field [0001] The invention relates to an antioxidant composition applied to cosmetics and a preparation method thereof. Background technique [0002] Ashitaba (Angelica keiskei koidzumi) is a perennial herbaceous plant of Umbelliferae, also known as Ashitaba, Hachijo Celery, Binhai Angelica, etc. It is native to Izu and Hachijo Islands in Japan. Ashitaba is rich in secondary metabolites such as vitamins, coumarins, and flavonoids. It has been used in food development, beverages, and pharmaceutical products in Japan, but related research in my country started relatively late. Studies have shown that Ashitaba extract has physiological effects such as anti-oxidation, enhancing human immunity, improving sleep, and delaying aging. [0003] At present, Ashitaba and its extracts are mainly used in the fields of functional food and medicine, and are rarely used in the field of cosmetics. The preparation method of Ashitaba extract usually uses water extraction method or a...
