Abstract
The invention discloses a compound plant extract and its preparation method and application. The preparation method of the extract comprises the following steps: taking the following raw materials in parts by weight: 1 to 3 parts of black beans, 1 to 3 parts of black tea, 1 to 3 parts of black rice, 1 to 3 parts of dried black currant, moisturizing 0-60 parts of solvent, 20-60 parts of deionized water, 0.2-1.0 parts of preservative, 0.5-2.0 parts of antibacterial agent; after heating the moisturizing solvent and water to 90-110°C, add black beans, black tea, and black rice , Dried blackcurrant fruit, heat preservation and stirring for 1 to 4 hours, after concentration, dehydration and deodorization, cool to obtain the concentrate and condensate, mix the condensate and concentrate evenly, then add preservatives and bacteriostats and mix evenly, after filling Obtain the extract. The prepared extract has an inhibition rate of tyrosinase of over 80%, which has an excellent therapeutic effect on reducing melanin deposition, and is also conducive to the gradual restoration of the damaged skin's natural barrier during the skin's own metabolism, and continuous skin care , suitable for long-term nourishing and conditioning of the skin.
Description
technical field [0001] The invention relates to the technical field of cosmetics, in particular to a compound plant extract and its preparation method and application. Background technique [0002] Among the existing whitening and anti-aging products, most of the high-efficiency whitening and anti-aging products on the market currently use hormone-based raw materials, or use other prohibited and restricted ingredients. For example, dexamethasone, mercury, kojic acid, etc., can cause skin allergies, damage, dark spots, skin loss of elasticity, and side effects such as melanosis, which is not conducive to the healthy circulation of the skin. High-efficiency whitening products on the market widely use prohibited ingredients , such as hydroquinone, kojic acid, hydroquinone, hormones, etc., contain skin irritation and damage the physiological health of the skin. Contents of the invention [0003] The purpose of the present invention is to provide a compound plant extract and i...
