Abstract

The invention discloses an eaglewood extract with allergy-relieving and anti-allergy effects, and a preparation method and application thereof. The method comprises the following steps: (1) grinding eaglewood, and then heating and extracting the eaglewood in an ethanol solution; (2) performing cooling and filtering, and extracting filter liquor for later use; (3) concentrating the filter liquor in the step (2) to obtain eaglewood extract concrete; (4) mixing and dissolving the eaglewood extract concrete in the step (3) and polyol, and performing filtering to obtain filter liquor namely the eaglewood extract with the allergy-relieving and anti-allergy effects. The method for preparing the eaglewood extract, provided by the invention, is simple and convenient to operate and suitable for large-scale production, and the purity of an obtained product is higher. The eaglewood extract provided by the invention has multiple effects of inhibiting the activity of hyaluronidase, scavenging free radicals, achieving anti-inflammation and anti-allergy, enhancing a skin barrier function and the like. The extract has an environmentally-friendly extraction mode, is healthy and safe, inhibits release of allergy mediators such as histamine, and can be widely applied to various cosmetics such as masks by serving as an active anti-allergy ingredient.

Description

technical field [0001] The invention relates to an agarwood extract with soothing and anti-allergy effects, a preparation method and application thereof. Background technique [0002] An allergic reaction is an abnormal or pathological reaction of the human body to an antigen. In the process of allergic reaction, the allergen (antigen) plays a direct role and is the external cause of the allergic reaction; while the body's immunity is low, and the oxidative damage of cells by a large number of free radicals is the internal cause of the allergic reaction. Skin allergy is a relatively common skin problem. With the increase in the use of cosmetics and other chemicals, environmental problems, the accelerated pace of life in modern society, and increased pressure, more and more people have sensitive skin. Coupled with some people's improper use of skin care products and other reasons, it is often easy to cause skin allergies, and allergic symptoms such as itching, scaling, redne...
