Problems solved by technology

[0008] At present, there have been reports on compositions or products for skin care compounded with one or more of Atractylodes macrocephala, Bletilla striata, and Baishui as raw materials, but these products generally have the following problems: 1. Most of the reports use Crude plant extracts, rather than functional components derived from plants; or unidentified main functional components in compositions or products, which can easily lead to poor stability or even invalid product effects; 2. Angelica dahurica is added to many compositions or products
Angelica dahurica is a plant component prohibited by the 2015 edition of the "Safety and Technical Specifications for Cosmetics"; 3. The mechanism of action is single
Skin aging involves a series of factors, such as skin barrier damage caused by skin dryness, skin peroxidation, skin inflammation, skin microecological imbalance, etc., while the currently reported compositions or products have a single mechanism of action, and many active ingredients Does not have a synergistic effect, it is difficult to achieve the best expected anti-aging skin effect

Embodiment 1

[0046] 1. The preparation of the extract is as follows:

[0047] 1. Bletilla striata extract

[0048] The dried Bletilla striata was crushed and passed through a 80-mesh sieve, mixed with 50°C hot water at a material-to-liquid ratio of 1:15 (g / mL), and extracted in a 50°C water bath for 1 hour. After cooling down to room temperature, the extract was centrifuged at 5000rpm for 10 minutes, and the supernatant was taken to obtain the extract. The bletilla striata extract was freeze-dried to obtain the bletilla striata extract. The polysaccharide content (with glucose as standard) in the Bletilla striata extract was 69.8% detected by the sulfuric acid-phenol colorimetric method.

[0049] 2. Atractylodes macrocephala extract

[0050] The dried Atractylodes macrocephala is crushed and passed through a 80-mesh sieve, mixed with 65°C hot water at a ratio of 1:20 (g / mL) to liquid, and then extracted in a 65°C water bath for 1.5 hours. After cooling down to room temperature, the ext...

Embodiment 2

[0071] (1), the preparation of extract is as embodiment 1.

[0072] (2) Take and mix the obtained extracts to obtain an external composition with anti-aging properties, which is compounded from Bletilla striata polysaccharide extract, Atractylodes macrocephala polysaccharide extract, Atractylodes polyphenols extract and lotus flower flavonoids extract. In parts by weight, the ingredients are 1 part of bletilla striata polysaccharide extract, 1 part of atractylodes polysaccharide extract, 1 part of rhizome polyphenol extract, and 1 part of lotus flower flavonoid extract.

[0073] (3) Taking the emulsion as an example, explain the application of the external composition in skin care products and test its effect on the moisturizing, microecology and roughness of human skin.

[0074] An emulsion of a composition for external use, prepared from the following components by weight:

[0075] Oil phase: polyglycerol-3-diisostearate 2.5g, cetyl alcohol 0.6g, olive oil 4.2g;

[0076] W...

Abstract

The invention discloses an external composition for resisting skin aging and application thereof, and belongs to the technical field of daily cosmetics. The external composition is formed by compounding a bletilla striata polysaccharide extract, an atractylodes macrocephala polysaccharide extract, an ampelopsis japonica polyphenol extract and a lotus flavone extract according to the mass ratio of (1-4): (1-6): (1-3): (1-3), the composition is prepared into emulsion to be used for human skin, a stronger skin aging resisting effect is shown, the four extracts have a synergistic interaction effect, and the anti-skin aging effect of the composition is obviously improved.

Description

technical field [0001] The present invention relates to the technical field of daily cosmetics, in particular to an external composition with anti-aging effects on the skin compounded from Atractylodes macrocephala polysaccharide extract, Bletilla striata polysaccharide extract, Radix striata polyphenol extract and lotus flower flavonoid extract. its application. Background technique [0002] Skin aging refers to the aging caused by environmental factors such as light (sun exposure) and air pollution, and lifestyle factors such as diet, sleep, and exercise. dilation, pigmentation, etc. Current research shows that the important means to fight skin aging are as follows: [0003] 1. Moisturize. External environmental factors or genetic factors can lead to a decline in the water retention capacity of the skin, which in turn affects the hydration state of the stratum corneum of the skin. The physical properties of the skin will change accordingly, its flexibility and plasticit...
