Description

Skin-care composition, preparation method and application thereof

Technical Field

The application relates to a skin care composition and a preparation method and application thereof, in particular to a skin care composition and a preparation method and application thereof, and a skin care essence containing the skin care composition, belonging to the field of cosmetics.

Background

In the current world, the problems of skin aging and relaxation plague people's lives. Generally, the skin aging and sagging are caused by four factors: natural aging of human body: with age, collagen loss causes skin aging relaxation; the microbiome balance of the skin is destroyed and the skin also ages and relaxes; exposure to contaminated environments, exposure to sunlight also causes aging relaxation of the skin; gravity and the like may also cause sagging and sagging of the skin.

In the prior art, in order to prevent skin from sagging, losing elasticity, causing wrinkles and the like, and keep skin youthful, anti-aging products mixed with various components such as hydrolyzed collagen, hyaluronic acid, polypeptide, retinol and derivatives thereof have been proposed. However, if these ingredients are used in large amounts, there are problems in terms of anti-aging effects, skin feel in use, and safety. If the molecular weight of the hydrolyzed collagen is too large, the hydrolyzed collagen is not easy to penetrate through the skin barrier of the human body to reach the dermis layer; hyaluronic acid cannot substantially slow down the loss of collagen; polypeptides and retinol present a certain irritation and safety risk to the skin, etc. In order to obtain a skin care product which has the effect of improving tension and can slow down skin aging after long-term use from the aspect of reducing environmental pollution, a lot of reports are not yet available at present.

Citation 1 discloses a skin tightening, nourishing and moisturizing composition, and a preparation method and application thereof. The composition contains traditional Chinese medicine essence components, wherein the traditional Chinese medicine essence components are extracts of polygonum multiflorum, bolbostemma paniculatum, angelica sinensis, gardenia and gallnut; the preparation method comprises the following steps: 1) Mixing the Chinese medicinal essence, antiallergic component, humectant and purified water, stirring, heating to 80-90deg.C, and dissolving completely to obtain water phase; 2) Mixing oil, antioxidant component and emulsifier, stirring, heating to 80-90deg.C, and dissolving completely to obtain oil phase; 3) Adding the water phase into the oil phase at 80-90deg.C, homogenizing and emulsifying for 3-20min, and cooling to 40-50deg.C; adding hydrolyzed collagen, hydrolyzed silk water solution, and essence, and stirring for 5-15 min; the composition of the application improves the blood circulation of the skin, so that the skin is tense and elastic; can moisten skin. Wherein multiple functional ingredients are used, resulting in excessive costs and their inability to block penetration and damage of contaminants.

Reference 2 discloses a multidirectional extraction and tightening polypeptide essence, which is an aqueous formula system and comprises the following components in parts by weight: 50-75 parts of aloe vera extract, 5-10 parts of active free radical scavenger, 5-10 parts of palmitoyl pentapeptide-4 3-10 parts of pseudoalteromonas fermentation product extract, 1-3 parts of creatine HCl, 2-8 parts of tripeptide-1 copper, 0.1-1 part of acrylic acid (ester)/C12-22 alkanol methacrylate copolymer, 3-11 parts of film-forming water-locking auxiliary agent, 3-8 parts of humectant and 0.3-0.8 part of preservative; however, the extraction tension polypeptide essence cannot reduce the pollution of the environment to the skin, cannot provide exogenous protection to the skin, and cannot block the penetration and damage of pollutants.

Therefore, it is an urgent need to develop a skin care composition that can reduce environmental pollution to the skin and has a tightening effect.

gum acacia: 0.5-2%, preferably 0.6-2%.

The application can reduce the pollution of the environment to the skin and pull the skin by combining the four functional components, thereby solving the problem of loose skin and slowing down the aging of the skin after long-term use. Further, the present application imparts exogenous protection to the skin, resembling the second layer of skin, and blocks penetration and damage of contaminants. Specifically:

biological sugar gum-4

The biological sugar gum-4 is generally obtained by fermentation, can form a film with effective protection function on the surface of the skin, and can reduce the damage of ultraviolet rays and external pollution to the skin. And has a certain moisturizing effect. In addition, the biological glycocoll-4 can improve the activity of deacetylase, has a certain relieving function, and can resist inflammatory aging.

Specifically, in the present application, the biogel-4 is added in an amount of 20 to 40%, preferably 25 to 40%, more preferably 28 to 40%, still more preferably 30 to 40%, based on 100% of the total mass of the lift-tensioning skin composition, for example: the addition amount of the biological sugar gum-4 can be 22%, 32%, 35%, 38% and the like. In the present application, the addition of the biose-4 is higher than 40%, which gives a sticky feeling on the skin and gives uncomfortable feeling to the user.

Alginate salts

In the present application, alginate is a byproduct obtained after iodine and mannitol are extracted from kelp of brown algae or gulfweed, and its molecule is formed by connecting beta-D-mannuronic acid (beta-D-mannuronic acid, M) and alpha-L-guluronic acid (alpha-L-guluronic acid, G) according to (1- > 4) bond, and is a natural polysaccharide with stability, solubility, viscosity and safety.

When the amount of the alginate added is less than 0.5%, stability is affected, and when the amount of the alginate added is more than 2%, stability is not improved but cost is increased. In the present application, when the amount of alginate added is 0.5 to 2%, excellent stabilization can be achieved.

In some specific embodiments, the alginate comprises sodium alginate and/or potassium alginate, preferably sodium alginate. Sodium alginate is a natural polysaccharide and the lift-tensioning skin composition applied to the application has excellent stability, solubility, viscosity and safety.

Aureobasidium pullulans

The pullulanase polysaccharide is also called pullulan polysaccharide, and is extracellular pure natural high molecular polysaccharide produced by taking starch or saccharide as a raw material and fermenting by microorganisms. The pullulanase polysaccharide has very good thickening effects of salt resistance, enzyme resistance, heat resistance and pH value change resistance. The pullulanase polysaccharide has strong film forming property, and a film formed by drying an aqueous solution of the pullulanase polysaccharide on a metal plate has strong gas barrier property to oxygen and nitrogen. The pullulanase polysaccharide is easy to form a water-soluble edible film, so that exogenous protection of skin can be given. And the pullulanase polysaccharide has better compatibility with other water-soluble high polymer substances.

Specifically, in the present application, the pullulanase polysaccharide is added in an amount of 0.5 to 2%, preferably 0.8 to 2%, more preferably 0.8 to 1.8%, still more preferably 1 to 1.5%, based on 100% by weight of the total weight of the lift-tightening skin-contacting composition, for example: the addition amount of pullulanase polysaccharide can be 0.6%, 0.7%, 0.9%, 1.1%, 1.2%, 1.4%, 1.6%, etc. The addition of pullulanase polysaccharide is less than 0.5%, so that the pullulanase polysaccharide cannot play a protective role, and the addition of pullulanase polysaccharide is more than 2%, so that mud rubbing is easy to cause.

Gum arabic

GUM arabic (ACACIA SENEGAL GUM), a natural vegetable GUM, mainly comprises arabinose, galactose, glucuronic acid, etc. Gum arabic generally consists of two components, 70% of which consist of polysaccharides containing no or small amounts of N, and the other of which consist of protein structures with high relative molecular masses; the polysaccharide is combined with hydroxyproline and serine in protein peptide chain by covalent bond, the total protein content is about 2%, and the content of special variety can reach 25%; whereas the polysaccharide molecules linked to proteins are highly branched acidic polysaccharides, which generally have the following composition: d-galactose, L-arabinose, D-glucuronic acid, L-rhamnose, 4-O-methyl-D-glucuronic acid and the like; beta-D-galactopyranose may be linked in the gum arabic backbone by 1, 3-glycosidic bonds, while the side chains may be linked by 1, 6-glycosidic bonds. The gum arabic has natural good collagen component, can be biodegraded, and has good skin tolerance.

Specifically, in the present application, the gum arabic is added in an amount of 0.5 to 2%, preferably 0.6 to 2%, more preferably 0.6 to 1.8%, still more preferably 0.6 to 1.5%, based on 100% by weight of the total weight of the lift-tensioning skin composition, for example: the addition amount of pullulanase polysaccharide can be 0.7%, 0.8%, 0.9%, 1%, 1.2%, 1.4%, 1.6%, etc. When the addition amount of the gum arabic is less than 0.5%, the effect is not obtained, and when the addition amount of the gum arabic is more than 2%, the skin feel is extremely sticky.

Furthermore, the application uses four functional components of biological sugar gum-4, alginate, pullulanase polysaccharide and gum arabic gum, which can play a synergistic role, so that the problems of skin relaxation can be solved by reducing the pollution of the environment to the skin and pulling up the skin, and the skin is recovered to be compact.

In some specific embodiments, the mass ratio of the biose-4, the alginate, the pullulanase polysaccharide, and the gum acacia is 20-60:0.5-3:0.5-3:1, for example: 25-55:0.6-2.5:0.6-2.5:1, 30-50:0.8-2:0.8-2:1, 35-45:0.9-1.5:0.9-1.5:1, etc. When the mass ratio of the biogel-4 to the alginate to the pullulanase polysaccharide to the gum arabic is 20-60:0.5-3:0.5-3:1, the effects of the biogel-4 to the alginate to the pullulanase polysaccharide to the gum arabic can be better exerted.
