Description

Skin refreshing lotion, preparation method thereof and collagenase inhibitor
Technical Field
The invention relates to skin refreshing lotion, a preparation method thereof and a collagenase inhibitor, belonging to the field of cosmetics.
Background
Collagen is mainly produced by fibroblasts in the dermis layer, is a main component of the dermis layer, and can maintain the structure of the skin and endow the skin with toughness and elasticity. The collagen content and distribution determine the youth or not of the skin. However, abnormal reduction of collagen content causes thinning of the dermis, skin sagging, loss of elasticity, appearance of wrinkles, and affects the quality of life of people. With the ongoing and intensive research on collagen, researchers have found that collagenase plays an important role in the dynamic balance of skin collagen, and its overexpression and abnormal activation are one of the major causes of skin aging. Therefore, inhibiting the activity of collagenase can block the degradation of collagen of skin, increase the content of collagen, and realize the anti-aging effect.
The main approaches to skin anti-aging and skin care include the following aspects, with respect to factors affecting the collagen content of the skin: (1) increasing collagen synthesis by stimulating proliferation of fibroblasts in the dermis layer; (2) increasing the total amount of collagen in the dermis by stimulating the speed of synthesizing collagen by fibroblasts through active factors; (3) the degradation speed of the collagen is slowed down by inhibiting the catalytic activity of collagenase, a key enzyme for degrading the collagen in the dermis, so that the anti-aging purpose is achieved; (4) through sun protection, the damage of ultraviolet rays in sunlight to collagen in the skin is prevented, and the photoaging of the skin is slowed down; (5) the induced expression of collagenase and abnormal cross-linking of biomacromolecules is slowed down by scavenging excess oxygen free radicals in the skin using antioxidants.
In order to prevent skin from sagging, losing elasticity, wrinkling, etc., and keep skin young, anti-aging products mixed with various components such as hydrolyzed collagen, hyaluronic acid, polypeptide, retinol and its derivatives have been proposed in the prior art. However, if these ingredients are used in large amounts, problems arise in the actual anti-aging effect, the feeling of use, and safety. If the molecular weight of the hydrolyzed collagen is too large, the hydrolyzed collagen is not easy to permeate the skin barrier of the human body to reach the dermis; hyaluronic acid cannot essentially slow down the loss of collagen; the polypeptide and the retinol have certain irritation and safety risks to the skin, and the like.
With the increase of attention of people to skin health, the development of a natural anti-aging agent with safety, stability, obvious effect and high cost performance has become one of the main research directions of the current pharmaceutical and cosmetic industries, and has a very good development prospect.

<First aspect>
A first aspect of the invention provides a collagenase inhibitor comprising: the collagenase inhibitor comprises a ginseng extract and a chamomile extract, wherein the ginseng extract is added in an amount of 30-70% and the chamomile extract is added in an amount of 30-70% based on the total mass of the collagenase inhibitor.
The inventors of the present invention found that using a combination of a chamomile extract and a ginseng extract, an excellent synergistic effect can be produced, and thus, the activity of collagenase can be inhibited to achieve an anti-aging effect.
Specifically, in the present invention, the mass ratio of the ginseng extract to the chamomile extract is 1:0.43 to 2.2, preferably 1:0.44 to 2.18, more preferably 1:0.45 to 2.16, even more preferably 1:0.46 to 2.14, even more preferably 1:0.47 to 2.12, and even more preferably 1:0.48 to 2.1. When the mass ratio of the ginseng extract to the chamomile extract is within the above range, a synergistic effect can be further exhibited, and the collagenase activity inhibition effect is excellent.
The method for preparing the collagenase inhibitor of the present invention is not particularly limited, and may be a method generally used in the art, and specifically may include a step of mixing the components of the collagenase inhibitor. For example, the ginseng extract and the chamomile extract are mixed uniformly by conventional mixing means.
Collagenase
Collagenases belong to one class of Matrix Metalloproteinases (MMPs). Matrix metalloproteinases are a family of endopeptidases with a zinc ion-dependent biological activity and the ability to degrade the extracellular Matrix (ECM). Collagenase mainly acts to degrade collagen and elastin in dermis, and its Tissue Type Inhibitor (TIMPs) specifically inhibits the activity of collagenase by covalently binding with its highly conserved zinc binding site, co-regulates the metabolism of the matrix, and maintains the structure of the dermis.
The collagenase includes interstitial collagenase (MMP-1), polymorphonuclear collagenase (MMP-8) and collagenase 3 (MMP-13). Among them, interstitial collagenase, also known as collagenase-1, has various functions and can act on different substrates. Interstitial collagenase degrades several matrix molecules, such as aggrecan, multipotent glycans, basement membrane proteoglycans, casein, nidogen, serine protein inhibitors, and mucin-C. Thus, interstitial collagenases play a key role in the physiological repair of the extracellular matrix. The invention is mainly based on the important function of interstitial collagenase in the skin aging process, and inhibits the activity of interstitial collagenase, thereby reducing the inflammatory reaction and wrinkles of the skin, and being used as a way for delaying aging to realize the anti-aging function.
It is to be noted that the object of the collagenase inhibitor of the present invention is to inhibit collagenase activity, for example: inhibit the activity of interstitial collagenase, but not the expression of collagenase.
Ginseng extract
Ginseng (Panax ginseng C.A. Meyer) is a perennial herbaceous plant of Araliaceae, and is one of the most potential medicinal plant resources in Changbai mountain.
Ginseng contains a variety of chemical components, such as: ginsenoside, ginseng polysaccharide, ginseng protein, polypeptide and the like. Wherein Ginsenoside (Ginsenoside) is a steroid compound, and is triterpene saponin with dammarane type and tetracyclic triterpene as main structure in chemical structure. Ginsenoside is one of representative active ingredients in ginseng, and is widely present in plants of the genus panax. The ginseng polysaccharide is another effective active ingredient of ginseng and is a good natural drug effect ingredient. The combined application of the ginseng polysaccharide and the small molecular chemotherapeutic drug can repair and reduce the damage of the chemotherapeutic drug to the human immune system, and play the role of synergy and attenuation.
The Ginseng radix extract can be used as a natural additive for cosmetic production. Ginsenoside has effects of resisting oxidation, preventing ultraviolet, and protecting skin, and is one of physiologically active substances in Ginseng radix. Ginsenoside can also stimulate the activity of skin fibroblasts, promote collagen synthesis, and increase the SOD content and activity in skin within a certain range. The Ginseng radix extract has high ginsenoside content, and can scavenge DPPH (1, 1-diphenyl-2-trinitrophenylhydrazine) free radical.
In the invention, the ginseng extract is added in an amount of 30-70% by mass based on the total mass of the collagenase inhibitor. When the addition amount of the ginseng extract is 30-70%, the collagenase activity can be effectively inhibited. Specifically, the ginseng extract may be added in an amount of 35%, 40%, 45%, 50%, 55%, 60%, 65%, etc.
Chamomile extract
Chamomile (Matricaria recutita L), also known as chamomile, is an annual herb of the chamomilla genus (Matricaria) of the family Compositae (Compositae). Chamomile is an important medicinal plant and spice raw material, and is mostly used as a medicine by using inflorescence or whole herbs. Chamomile is sweet, fragrant, slightly bitter in taste and rich in bioactive substances.
Essential oil extracted from flos Matricariae Chamomillae contains terpenoids, bisabolol, chamazulene, etc. as main ingredients, and has effects of diminishing inflammation, resisting allergy, relieving spasm, inhibiting bacteria, clearing heat, treating ulcer, etc.; the chamomile is rich in phenolic acid, coumarins and flavonoids, and has the effects of resisting oxidation, protecting liver, resisting vascular proliferation, diminishing inflammation, resisting allergy, resisting virus and the like.
In the invention, the chamomile extract is added in an amount of 30-70% by mass based on the total mass of the collagenase inhibitor. When the addition amount of the chamomile extract is 30-70%, collagenase activity can be effectively inhibited. Specifically, the added amount of the chamomile extract may be 35%, 40%, 45%, 50%, 55%, 60%, 65%, or the like.
<Second aspect of the invention>
In a second aspect, the invention provides a skin-refreshing lotion comprising a collagenase inhibitor according to the first aspect of the invention and a penetration enhancer; the invention can inhibit the activity of collagenase, particularly the activity of interstitial collagenase by adding a proper amount of collagenase inhibitor, so that the skin refreshing lotion has excellent anti-aging effect and can improve the skin elasticity. In order to promote the absorption of the collagenase inhibitor by the skin, the skin refreshing lotion also uses a penetration enhancer. By using a penetration enhancer, the collagenase inhibitor of the present invention can be exerted to a greater extent.
Wherein, the addition amount of the collagenase inhibitor is 0.01-10% based on the total mass of the skin-refreshing lotion, such as: 0.5%, 1%, 2%, 3%, 5%, 6%, 7%, 8%, etc. When the collagenase inhibitor is added in an amount of 0.01-10%, the elasticity of the skin after the collagenase inhibitor is used is increased. When the addition amount of the collagenase inhibitor is less than 0.01%, the collagenase inhibitor cannot play a role in resisting aging; when the addition amount of the collagenase inhibitor is more than 10%, the content of the collagenase inhibitor is too high, the cost is too high, and the corresponding anti-aging effect is not obviously improved.
The penetration enhancer is added in an amount of 0.01-10% by mass of the skin-refreshing lotion, for example: 0.5%, 1%, 2%, 3%, 5%, 6%, 7%, 8%, etc. When the addition amount of the penetration enhancer is less than 0.01%, the penetration enhancing effect is not significant. When the addition amount of the penetration enhancer is more than 10%, the penetration enhancer cannot further function.
In the present invention, the penetration enhancer includes one or a combination of two or more of propylene glycol, bis-diethoxydiol cyclohexane 1, 4-dicarboxylate, and chitosan. The invention preferably uses the combination of propylene glycol and bis-diethoxydiol cyclohexane 1, 4-dicarboxylate, and the propylene glycol and bis-diethoxydiol cyclohexane 1, 4-dicarboxylate have synergistic effect, so that the absorption effect of collagenase inhibitor can be more excellent.
When a combination of propylene glycol and bis-diethoxydiol cyclohexane 1, 4-dicarboxylate is used as the penetration enhancer, the addition amount of propylene glycol is 0.01-5% and the addition amount of bis-diethoxydiol cyclohexane 1, 4-dicarboxylate is 0.01-5% based on the total mass of the skin-refreshing lotion. When the addition amount of the propylene glycol is 0.01-5% and the addition amount of the bis-diethoxydiol cyclohexane 1, 4-dicarboxylate is 0.01-5%, the absorption effect of the collagenase inhibitor can be effectively improved.
