Problems solved by technology

For example, the molecular weight of hydrolyzed collagen is too large, and it is difficult to penetrate the skin barrier of the human body to reach the dermis; hyaluronic acid cannot essentially slow down the loss of collagen; peptides and retinol have certain irritation and safety risks to the skin, etc.

preparation example Construction

[0043] The preparation method of the collagenase inhibitor of the present invention is not particularly limited, and may be a common method in the art, specifically including the step of mixing the components of the collagenase inhibitor. For example, the wild chrysanthemum flower extract and the chamomile extract are uniformly mixed in a conventional mixing manner.

[0044] Collagenase

[0045] Collagenase belongs to a class of matrix metalloproteinases (Matrix Metalloproteinase, MMPs). Matrix metalloproteinases are a family of endopeptidases whose biological activity depends on zinc ions and has the ability to degrade extracellular matrix (Extra-Cellar Matrix, ECM). The main function of collagenase is to degrade collagen and elastin in the dermis, and its tissue inhibitors (Tissue Inhibitors of Metalloproteinase, TIMPs) specifically inhibit the activity of collagenase by covalently binding to its highly conserved zinc binding site , jointly regulate matrix metabolism and...

Embodiment

[0091] Embodiments of the present invention will be described in detail below in conjunction with examples, but those skilled in the art will understand that the following examples are only used to illustrate the present invention, and should not be considered as limiting the scope of the present invention. Those who do not indicate the specific conditions in the examples are carried out according to the conventional conditions or the conditions suggested by the manufacturer. The reagents or instruments used were not indicated by the manufacturer, and they were all commercially available conventional products.

[0092] Wild chrysanthemum extract: Quzhou Zhanhong Biotechnology Co., Ltd.;

[0093] Chamomile extract: Quzhou Zhanhong Biotechnology Co., Ltd.

Embodiment 1-5

[0099] Provides wild chrysanthemum flower extract and chamomile extract as collagenase inhibitors. Wild chrysanthemum extract and chamomile extract are in mass ratio 3:1 (embodiment 1), 2:1 (embodiment 2), 1:1 (embodiment 3), 1:2 (embodiment 4), 1:1 3 (Example 5) After mixing, a collagenase inhibitor was obtained. The collagenase inhibitors of Examples 1-5 were respectively dissolved in 5 groups of deionized water corresponding to the volumes of Comparative Examples 1-5. Examples 1-5 can obtain 5 groups of test solutions corresponding to the concentrations of Comparative Examples 1-5. Wherein, among the collagenase inhibitors, the contents (mass %) of the extracts of Chrysanthemum officinalis and Chamomile are shown in Table 1 below, and the logarithmic mass concentrations of the collagenase inhibitors are shown in Table 3 below.

Abstract

The invention provides a moisturizing lotion, a collagenase inhibitor and a preparation method of the collagenase inhibitor. The moisturizing lotion comprises a collagenase inhibitor and a penetration enhancer, and the addition amount of the collagenase inhibitor is 0.01-10% based on the total mass of the moisturizing lotion; the addition amount of the penetration enhancer is 0.01-10% ; the collagenase inhibitor comprises a wild chrysanthemum flower extract and a chamomile extract, and based on the total mass of the collagenase inhibitor, the addition amount of the wild chrysanthemum flower extract is 27-74%, and the addition amount of the chamomile extract is 26-73%. The moisturizing lotion disclosed by the invention is mild in formula and can effectively improve skin elasticity, so that an anti-aging effect is achieved.

Description

technical field [0001] The invention relates to a moisturizing milk, a collagenase inhibitor and a preparation method thereof, belonging to the field of cosmetics. Background technique [0002] Collagen is mainly produced by fibroblasts in the dermis and is the main component of the dermis. It can maintain the structure of the skin and give the skin toughness and elasticity. The content and distribution of collagen determine the youthfulness of the skin. However, the abnormal reduction of collagen content will cause the thinning of the dermis, loose skin, loss of elasticity, and wrinkles, which will affect people's quality of life. With the deepening of research on collagen, researchers have found that collagenase plays an important role in the homeostasis of skin collagen, and its overexpression and abnormal activation are one of the main causes of skin aging. Therefore, inhibiting the activity of collagenase can block the degradation of skin collagen, increase the conten...
