Description

Oil-control acne-removing composition and application thereof

Technical Field

The invention relates to the technical field of cosmetics, and particularly relates to an oil-controlling acne-removing composition and application thereof.

Background

The mask market is one of the fastest-growing segment markets of China's daily chemical industry at present, according to Nielsen retail research data, the continuous three-year composite growth rate of the mask market in 2012-2014 exceeds 21.9%, and the conservative sales in 2015 reaches 300 hundred million. The fast development of the facial mask is closely related to the efficacy, and the facial mask can comprehensively solve 5 big problems of skin: the facial mask has the functions of moisturizing, controlling oil, whitening, resisting allergy, resisting aging and removing acnes.

The daily skin care product only aims at partial problems and cannot comprehensively and quickly improve the skin condition. The facial mask temporarily isolates outside air and pollution by covering the facial mask on the skin for a short time, improves the skin temperature, expands pores, promotes secretion and metabolism of sweat glands and promotes oxygen content of the skin to rise. The water in the mask penetrates into the horny layer of the skin to soften the skin and increase the elasticity; the mud film adheres to and removes dirt, metabolites, excess oil and the like on the skin surface and in pores.

The tear-off facial mask is a facial mask which is applied to the face and becomes a film after being dried. It can keep the skin of face warm, and promote blood circulation and metabolism. After the mask is dried, dirt in pores is taken out in a tearing mode to achieve the effect of removing dead skin.

The earliest tear-off masks were powdered, with a synergistic effect of natural polymeric thickeners and porous adsorptive diatomaceous earth in the formulation, and magnesium oxide and calcium sulfate dried to form a dense sealing film.

In addition, the jelly-shaped tear-off facial mask mainly takes polyvinyl alcohol as a main raw material in the formula, and the aqueous solution of the polyvinyl alcohol is transparent and stable and forms a uniform and closed transparent film after being dried. However, the drying speed of the polyvinyl alcohol is affected by the adding proportion of the ethanol and the polyhydric alcohol in the formula, and the polyvinyl alcohol can be completely dissolved by slowly stirring for a long time.

The traditional tear mask has the defects that the tear mask has large damage to the skin, so that symptoms such as large skin pores and skin allergy are easily caused, and meanwhile, the mask has poor water replenishing capacity.

The traditional mud mask contains rich mineral substances and has the effects of diminishing inflammation, sterilizing, removing grease, inhibiting acne and shrinking pores. The minerals and microelements can also supplement nutrition for skin, and achieve the purpose of caring skin. When in use, a closed mud film is formed on the skin, and the effects of deep moisturizing, skin repairing, cell vitality recovery and cutin removal are achieved.

The main components of the mud paste type mask are solid powder, a surfactant and a high molecular polymer. Solid powders are typically kaolin, silica gel and clay; the surfactant has the solid dispersing effect in the formula, the high molecular polymer has the suspension stabilizing effect, and the micelle formed by the surfactant and the high molecular polymer has the synergistic effect on the year and the stability of the mud mask, but the traditional mud mask has the defects of difficult cleaning and poor experience for consumers.

Oily skin is likely to cause acne, 80% of teenagers suffer from acne problems, and paint is a hormone disorder caused by adolescence. Among patients going to dermatologists for diagnosis and treatment, oily skin and acne prone skin problems account for 20%.

Oily skin is a problem that afflicts many people and is found on the upper parts of the face, head, cleavage, and back that are often seen by those people. Oily skin does not bring about any aesthetic feeling: it is often considered a dire social barrier but is so compelling to be biased. It is intolerable and can sometimes cause non-negligible psychological problems.

The existing mud paste type mask has single function and cannot meet the requirement of multiple effects of consumers.

Tear-off type cosmetics, which use polymeric compound film-forming agents as the main active ingredient, are often used in styling products and styling products, and are capable of forming a transparent, firm film on hair fibers, thereby maintaining the styling effect of hair. Meanwhile, the sunscreen agent can also improve the waterproofness, the fastness and the durability of skin care products, sunscreen products and color cosmetic products.

Currently, there are mainly 2 film formers on the market: a polyvinyl pyrrolidone (vinyl pyrrolidone homopolymer or vinyl pyrrolidone/vinyl acetate copolymer) film former and a carboxylic acid resin (acrylate polymer or acrylate/acrylamide copolymer) film former.

Such film formers have the following disadvantages:

1) the carboxylic acid resin and the vinyl pyrrolidone product can easily bring sticky feeling to the skin;

2) the mechanical properties of the polymer forming a film on the skin or hair are difficult to master, and the film is usually very brittle;

3) in hair styling products, the carboxylic acid resin and the vinylpyrrolidone copolymer often require the addition of a solvent, so that the copolymer is difficult to dissolve in the production process, and the application of the copolymer in the hair styling products or aqueous products is very limited particularly for low-volatility organic substances.

On one hand, consumers increasingly prefer cosmetics capable of bringing natural effects (such as no sticky feeling of skin, tight feeling and the like); on the other hand, the cosmetic industry, including the united states, is beginning to follow the environmental regulations that limit the formulation of products, i.e., limit the amount of volatile organic compounds.

The oil-control acne-removing composition adopts the water-soluble polyurethane film forming agent, the dipropylene glycol which is beneficial to film forming and the mineral substance soil are selected for carrying out formula proportion optimization combination, the finally prepared mud film can be dried to form a film within 15-20 minutes of the habit of using a consumer and the habit of applying the film, and the formed soft film is subjected to hydration stress contraction by using water spraying, so that the film can easily and mildly peel off the skin, the problem of difficulty in cleaning the mud film is solved, and the skin care experience of using the mud film is pleasantly and interestingly for the consumer.

1 film formation mechanism

The aqueous polyurethane dispersion used (high molecular weight polyurethane dispersed in water). Emulsifiers are added to the polyurethane chains to maintain the stability of the dispersion, and the polyurethane chains are made to coalesce by reacting isocyanates with compounds containing active hydrogen (e.g., polyols, polycarbonates, and polyesters).

The properties of the polyurethane depend on its segment structure, and the aqueous polyurethane dispersion used in the present application has a hard segment composed of low molecular weight components (isocyanate and solubilizer) and a soft segment composed of high molecular weight components (amorphous rubbery state of polyol). The combination of soft and hard segments determines the mechanical properties of the polymer film.

The water-soluble polyurethane adopted by the application is a pure water dispersion, does not contain solvents such as N-methylpyrrolidone (NMP) or ethanol and the like, does not contain an antibacterial agent, and can be suitable for preparing cosmetics for sensitive people.

2 film Forming Process

A traditional preparation method of the tear-off facial mask adopts a polyvinyl alcohol film forming agent, and in order to obtain an ideal product performance, namely, a continuous polymer film is formed on the surface of skin, the drying time is short, the peel-off is easy, and auxiliary agents such as ethanol and the like are required to be added.

The water-soluble polyurethane adopted by the application is in a liquid pair form, so that no cosolvent is added, and the viscosity is not increased in the formula. The product film-forming process completely adopts a physical drying film-forming technology, and the film is formed by water evaporation and dispersed ion agglomeration at room temperature.

Residual moisture in the polymer matrix acts as a plasticizer to lower the glass transition temperature of the film. According to the film forming principle, in order to enable the film forming to be uniform, the lowest concentration in the formula of the water-soluble polyurethane is also determined, so that the film forming is uniform.

The mud film is prepared from the mineral kaolin and the water-soluble titanium dioxide, and the drying time of the formula is controlled to be about 15min-20min by adjusting the component content ratio of the mud film, so that the habit of using the mud film by a consumer is met. The water-soluble polyurethane selected by the application is used as a film forming agent, is convenient to use, does not need neutralization or low viscosity, is suitable for cold processing, and does not need to add a cosolvent; has good compatibility with various cosmetic components, has good elasticity retention under high humidity, is natural and fresh, and is not greasy.

3 film-Forming Properties are preferred

The mud film forming auxiliary agent is optimized in order to meet the characteristics of the mud film, so that the mud film can be formed in 15-20min within the film application habit time range of a consumer, is complete in film forming and easy to tear and form, and achieves the washing-free skin care experience like a patch type facial mask. In order to let moisture volatilize fast, let water-soluble polyurethane polymer can gather the integrated membrane, traditional way adds ethanol and promotes moisture volatilization rate, and this patent considers that ethanol skin care promotes consumer's allergic probability easily, has selected the mineral composition in the mud membrane to participate in moisture regulation of volatilizing.

In order to improve the tearing performance of the mud film and ensure the integrity of the torn mud film, the elasticity and the toughness of the water-soluble polyurethane film and the torn mud film are preferably developed, glycerin, propylene glycol and dipropylene glycol are compared, and finally, the dipropylene glycol is selected as the film forming auxiliary agent.

The film forming mechanism proposed by the patent is that moisture is volatilized and combined into a film through the acting force of a hydrogen bond.

Model of the effect of glycerol on film formation: glycerol will be inserted into the hydrogen bonds between PUDs, preventing the formation of hydrogen bonds, thereby disrupting the film-forming properties.

Model of the effect of propylene glycol on film formation: propylene glycol will be inserted in the hydrogen bonds between PUDs, preventing the formation of hydrogen bonds, thus destroying the film-forming properties.

Model of the effect of dipropylene glycol on film formation: dipropylene glycol does not intercalate into hydrogen bonds between the PUDs, preventing the formation of hydrogen bonds, but rather adheres to the PUD chain, thereby helping the chain to be more elastic and the film to be stronger.

Mechanism of 4 pox formation

It is also a real international plague: approximately 40% of european women and 50% of asian women are suffering from oily skin. Glossy skin readily transforms into oily skin that is prone to acne.

Oily skin is characterized by dysregulation of seborrhea secretion by hormones. It causes unnatural shine to the skin, often causing discomfort to people: the face is shiny and the hair is oily and shiny, giving a greasy feel without a fresh feel.

the mechanism for effectively inhibiting the formation of acne is that because sebum secretion is regulated by male hormones, especially testosterone, sebaceous gland cells contain an enzyme, 5- α reductase, which can convert testosterone into Dihydroxytestosterone (DHT), which affects the activity of hair follicles, stimulates sebaceous glands, and causes excessive sebum secretion.

Excessive sebaceous gland secretion is often accompanied by the proliferation of flora, particularly acne bacilli produced in pores, which causes pain and inflammation. Sebaceous gland hypersecretion and glial cell hyperkeratosis cause pore blockage, propionibacterium acnes is anaerobic bacteria, bacteria are massively propagated in the pore blockage environment, lipase is produced, fatty acid formation is promoted, inflammation is aggravated, and a vicious circle is formed.

the acne treatment agent adopts the efficacy components to control endogenous acne mechanism, inhibit 5- α reductase, inhibit propionibacterium acnes, deeply clean, strip excessive keratinization dead skin and dredge pores, thereby repairing the acne skin from the inner and outer roots and effectively inhibiting the generation of acne.

5 acne-removing effective component

5.1 Octanylglycine, sarcosine, Cinnamomum zeylanicum bark extract (sepicontrol A5)

The caprylyl glycine, sarcosine and the cinnamomum zeylanicum bark extract selected by the patent are used as acne-removing efficacy components, and are effectively inhibited in a progressive manner based on each target point causing skin imbalance, and the efficacy mainly occurs in the following 5 aspects:

(1) inhibiting bacteria, improving immune defense, promoting expression of microbial protein HBD2, inhibiting bacterial reproduction at low concentration, and resisting bacteria causing imbalance and oily acne prone skin, and has the following antibacterial activities:

(2) can effectively reduce interleukin-1 α, resist elastase activity and resist free radical activity;

reduce the release of cytokine, interleukin-1 α (1L-1 α) which induces inflammation, and reduce inflammation caused by skin irritation.

The present patent uses caprylylglycine, sarcosine and Cinnamomum zeylanicum bark extract to have anti-elastase activity, reduce inflammation and protect extracellular media, and exhibit a stronger anti-elastase activity than zinc gluconate (positive reference).

Quantitative analysis of elastin inhibition activity using spectroscopic analysis: in the presence of elastase, N-methoxysuccinyl-alanine-proline-desmoic acid-pera-nitroanilide (a colorless substance) releases pera-nitroanilide (a colored substance), and DO/min is quantified at 410nm as% colored substance reduction ═ t-elastase activity.

(3) Controlling excessive keratinization and reducing expression of filaggrin;

can effectively control excessive keratinization, and the protein expression level of a keratinocyte proliferation marker is measured through filaggrin, so that the blockage of pores is reduced, and the generation of acnes is reduced.

(4) inhibiting 5 α -reductase activity and inhibiting excessive secretion of grease of sebaceous glands;

the application reduces the content of DHT (5 α -dehydrotestosterone) by inhibiting the activity of 5 α -reductase, thereby reducing the generation of 5 α -Androstenedione (ASD), inhibiting the activity of sebaceous glands and reducing the sebum secretion.

(5) Inhibit lipase activity, and control generation of peroxidized free fatty acid.

The lipase is inhibited by caprylyl glycine, sarcosine and the extract of the bark of the Cinnamomum zeylanicum, the production of free fat which is easily oxidized is controlled, and the reaction and stimulation of the skin are controlled.

5.2 Zinc Pyrrolidinone carboxylates

The zinc pyrrolidone carboxylate selected for use in the patent has dual biological activities, namely pyrrolidone carboxylic acid and zinc.

Pyrrolidone carboxylic acid, also known as L-PCA, pyroglutamic acid, was discovered by haitingner as early as 1882 as a cyclization product of glutamic acid, an amino acid abundantly present in plant substrates.

L-PCA exists in all tissues and organs of human body, and the content of human epidermis is high, and the L-PCA is located in Natural Moisturizing Factor (NMF) of epidermis, and plays a role in connecting ligaments.

Energy metabolism

precursors of the alpha-ketoglutarate/tricarboxylic acid cycle.

Protein synthesis

Collagen protein contains amino acids-proline and hydroxyproline precursor.

Skin hydration

L-PCA can be combined with active molecules and becomes a delivery carrier, and researches show that the biological activity of cations combined with L-PCA is greatly improved compared with common salts.

5.3 mechanism of action of PCA-Zinc

PCA-zinc is the zinc salt of pyrrolidone carboxylic acid, an active that brings about the dual efficacy of zinc and L-PCA simultaneously to the skin.

(1) inhibition of 5 α -reductase activity

by comparison with the inhibitory effect of capelin, zinc chloride and zinc PCA on the activity of 5 α -reductase.

PCA-zinc can remarkably inhibit the activity of 5 α -reductase at low dose (10)^-7M and 10^-6M, PCA-zinc) and inhibits 5 α -reductase more strongly than both zinc chloride and moroxydine, mainly because of its good cell permeability.

(2) Antibacterial effect

The propagation of harmful microorganisms, acne bacilli and white staphylococcus is the main cause of oily skin pain phenomena which are easy to breed acne. PCA-zinc is antibacterial mainly because it contains zinc, whose antibacterial properties have been confirmed by the determination of the Minimum Inhibitory Concentration (MIC) of PCA-zinc for different strains.

The MIC values of PCA-zinc for different bacteria were as follows:

bacterial strains	PCA-Zinc Minimum Inhibitory Concentration (MIC)%
		Acne bacillus	0.1％
Staphylococcus albus	0.5％
		Staphylococcus aureus	0.7％
Pseudomonas aeruginosa	0.7％
		Escherichia coli	0.7％
Candida utilis	0.7％
