Description

Technical Field

[0001] The present invention relates to a peeling gel cosmetic composition, and more particularly to a peeling gel cosmetic composition having a natural origin index of 90% or more.

Background Art

[0002] One of the skin care cosmetics is a peeling gel cosmetic. A peeling gel cosmetic is a cosmetic that exhibits a beauty effect by applying it to the skin to remove the stratum corneum of the skin and regenerate the skin.

[0003] As a peeling gel cosmetic, there is a chemical peeling gel containing α-hydroxy acid, fruit acid, glycolic acid, etc. These chemical peeling gels peel and regenerate the skin (such as the stratum corneum) by bringing an acid into contact with the skin. However, since chemical peeling gels have a high irritation to the skin, there are limitations in use, and they are used in beauty dermatology, aesthetic salons having a doctor's license, etc.

[0004] As a water-soluble polymer, there is a peeling gel containing carbomer or a cationic surfactant (for example, Patent Document 1). When this type of peeling gel is applied to the skin and massaged, a hydrogel is formed, and the water-soluble polymer (for example, carbomer) attached to the skin becomes insoluble and forms an aggregate. When becoming insoluble and forming an aggregate, the stratum corneum, sebum, dirt, etc. are taken into the aggregate and removed. As a result, the skin turnover is promoted.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Chemical peeling gels are highly irritating to the skin, so there is a demand for peeling gels made from safe, naturally derived ingredients. Furthermore, carbomer and cationic surfactants contained in peeling gels are synthetic compounds, not naturally derived ingredients. Changing water-soluble polymers like carbomer contained in peeling gels can lead to problems such as decreased stability over time, or the water-soluble polymers failing to form aggregates even with massage, resulting in a lack of peeling effect.

[0007] This invention has been made in view of the above circumstances, and aims to provide a novel peeling gel cosmetic composition that is made from naturally derived raw materials (ingredients), has excellent stability over time, and generates aggregates (exhibits a peeling effect) when applied to the skin and massaged. [Means for solving the problem]

[0008] The peeling gel cosmetic composition of the present invention, which has been able to solve the aforementioned problems, is characterized by containing 2% to 10% by mass of cellulose, 0.1% to 1.0% by mass of gellan gum, 0.1% to 2.0% by mass of xanthan gum, 0.5% to 5.0% by mass of carrageenan, 0.1% to 1.4% by mass of dextrin, and water.

[0014] The natural index as defined in ISO 16128 is an index that indicates the percentage of natural raw materials included. The index for raw materials is shown on a scale of 0 to 1, and the index for the product is shown as a percentage.

[0015] The natural origin index specified in ISO 16128 is an index that indicates the natural portion of naturally derived raw materials. The index for a single raw material is shown as a value between 0 and 1, while the index for mixed raw materials and products is shown as a percentage. Whether or not water is included should be clearly indicated near the index. If water is included, it is common to indicate what percentage of the index is water.

[0016] The peeling gel cosmetic composition of the present invention preferably has a naturally derived index (including water) of 90% or more, more preferably 95% or more, and most preferably 100% as defined in ISO 16128.

[0017] The peeling gel cosmetic composition of the present invention is characterized by containing cellulose, gellan gum, xanthan gum, carrageenan, and dextrin. By containing these components, the peeling gel cosmetic composition of the present invention has improved stability over time and exhibits a peeling effect.

[0018] The cellulose, gellan gum, xanthan gum, carrageenan, and dextrin used in this invention are all naturally derived raw materials that comply with ISO 16128 standards.

[0019] Cellulose is a naturally derived peeling ingredient that gently removes dead skin cells and smooths the skin surface. From this perspective, the cellulose content is preferably 2% by mass or more, more preferably 4% by mass or more, preferably 10% by mass or less, and more preferably 8% by mass or less.

[0020] Gellan gum stabilizes the texture of the peeling gel cosmetic composition and improves its stability. From this viewpoint, the gellan gum content is preferably 0.1% by mass or more, more preferably 0.3% by mass or more, preferably 1.0% by mass or less, and more preferably 0.5% by mass or less.

[0021] Xanthan gum is a naturally derived thickening agent that enhances the overall stability of the product. From this perspective, the xanthan gum content is preferably 0.1% by mass or more, more preferably 0.2% by mass or more, preferably 2% by mass or less, and more preferably 1% by mass or less.

[0022] Carrageenan is a thickening agent derived from seaweed that improves the feel of the product and enhances its adherence to the skin. The carrageenan content is preferably 0.5% by mass or more, more preferably 1% by mass or more, preferably 5% by mass or less, and more preferably 2% by mass or less.

[0023] The peeling gel cosmetic composition of the present invention contains dextrin. Dextrin improves the stability of other components and maintains the quality. From such a perspective, the content rate of dextrin is preferably 0.1% by mass or more, more preferably 0.2% by mass or more, preferably 1.4% by mass or less, and more preferably 0.6% by mass or less.

[0024] The peeling gel cosmetic composition of the present invention preferably contains an extract component. When the peeling gel cosmetic composition contains an extract component, the feeling of use is improved and the skin beautifying effect is exhibited. As the extract component, it is preferable to contain pomegranate extract, date palm extract, fig extract, apple extract, apricot extract, and grape extract.

[0025] Regarding the mechanism of improving the skin beautifying effect by containing these extracts, it is unclear, but it is considered that the skin beautifying active ingredients (polyphenol components) contained in these extracts activate skin cells and impart a skin beautifying effect.

[0026] Pomegranate extract is an extract extracted from the pomegranate (Punica granatum L.), a plant of the family Lythraceae, and is excellent in antioxidant and whitening effects. Pomegranate extract preferably contains ellagic acid as a polyphenol component.

[0027] Date palm extract is an extract extracted from the date palm (Phoenix dactylifera L.), a plant of the family Arecaceae, and is excellent in antioxidant and anti-wrinkle effects. Date palm extract preferably contains rutin as a polyphenol component.

[0028] Fig extract is an extract extracted from the fig (Ficus carica L.), a plant of the family Moraceae, and is excellent in anti-inflammatory and anti-tumor formation effects. Fig extract preferably contains epicatechin as a polyphenol component.

[0029] Apple extract is derived from the green apple (Malus pumila Mill.), a plant belonging to the Rosaceae family, and possesses excellent antioxidant and anti-allergic effects. Apple extract containing procyanidin as a polyphenol component is preferable.

[0030] Apricot extract is an extract derived from the apricot plant (Prunus armeniaca L.) of the Rosaceae family, and it has excellent antioxidant, antibacterial, and anti-wrinkle effects. Apricot extract containing catechins as a polyphenol component is preferable.

[0031] Grape extract is an extract derived from the grape (Vitis spp.), a plant of the Vitaceae family, and has excellent antioxidant, whitening, and anti-wrinkle effects. Grape extract preferably contains anthocyanins, myricetin, and resveratrol as polyphenol components.

[0032] In the peeling gel cosmetic composition of the present invention, the total content of the extract components is preferably 0.0001% by mass or more, more preferably 0.001% by mass or more, even more preferably 0.01% by mass or more, preferably 2% by mass or less, more preferably 1% by mass or less, and even more preferably 0.5% by mass or less. This is because the desired skin beautifying effect is more easily obtained when the total content of the extracts is within the above range.

[0033] The following mass ratios are preferable for the blending ratio of each extract. If the blending ratio of each extract is within the following range, a peeling gel cosmetic composition with a good feel and higher skin beautifying effect can be obtained. Pomegranate extract: 10% to 20% by mass is preferred, and about 17% by mass is more preferred. Date palm extract: Preferably 10% to 20% by mass, and more preferably about 17% by mass. Fig extract: 10% to 20% by mass is preferred, and about 17% by mass is more preferred. Apple extract: Preferably 10% to 20% by mass, and more preferably about 17% by mass. Apricot extract: 10% to 20% by mass is preferred, and about 17% by mass is more preferred. Grape extract: remainder (total extract is 100% by mass).

[0034] These extracts are all plant-derived and highly safe. There are no particular restrictions on the part of the plant used for extraction, as long as the desired effect is obtained. For example, the whole plant, or roots, stems, trunks, bark, buds, leaves, flowers, fruits, seeds, etc., can be used, with the use of fruits being preferable. Each extract used in this invention preferably contains polyphenol components in high purity. The polyphenol component content is preferably 90% by mass or more, and more preferably 98% by mass or more.

[0035] The plant parts used for extracting the extract may be used as is, or the parts may be processed before extraction. Specific examples of processing include juicing, drying, crushing, pressing, shredding, and fermentation. Furthermore, as long as the polyphenol components are present, the whole plant, or any part such as the roots, stems, trunk, bark, buds, leaves, flowers, fruits, or seeds may be used.

[0036] The method for extracting the aforementioned extract from each plant is not particularly limited, but examples include solvent extraction and supercritical fluid extraction. Either one of these methods may be used, or both may be used. Furthermore, each extraction method may be performed only once, or two or more times.

[0037] When extracting by solvent extraction, the solvent used is not particularly limited, but examples include water, methanol, ethanol, isopropanol, butanol, methyl ethyl ketone, 1,3-butylene glycol, ethylene glycol, propylene glycol, glycerin, acetic acid, and pentane. One of these solvents may be used, or two or more may be used in combination. From the viewpoint of suitably extracting polyphenols and using naturally derived raw materials, it is preferable to use water or ethanol.

[0038] When using water as the extraction solvent, the extraction temperature should be between 20°C and 100°C, preferably between 40°C and 70°C. This is because if the extraction temperature is too low, the polyphenol components will not be easily extracted. The type of water used for extraction is not particularly limited; tap water, purified water (distilled water, deionized water, etc.), mineral water, alkaline ionized water, etc., can be used.

[0039] When using aqueous alcohol as the extraction solvent, it is preferable that the alcohol concentration be 30% by mass or higher, preferably 50% by mass or higher. This is because if the concentration is less than 30% by mass, the amount of skin-beautifying active ingredients extracted tends to decrease. Furthermore, the extraction temperature should be between 0°C and 95°C, preferably between 20°C and 80°C. In addition, aqueous alcohol extraction should be repeated at various concentrations to improve the polyphenol content.

[0040] When extraction is performed by solvent extraction, the extraction method is not particularly limited; for example, any method such as continuous extraction, immersion extraction, or countercurrent extraction can be employed, and any apparatus can be used at room temperature or under reflux heating. Furthermore, when performing extraction using the above methods, only one of these methods may be used, or a combination of these methods may be used. In addition, these extractions may be performed only once or two or more times.

[0041] The specific method involves placing plant material or its processed product into a processing tank filled with an extraction solvent and eluting the polyphenol components while stirring. For example, when using water or aqueous alcohol as the extraction solvent, approximately 5 to 100 times the amount (by weight) of the raw material is used as the extraction solvent, and extraction is carried out for approximately 1 minute to 150 hours. After eluting the polyphenol components into the solvent, the extraction residue is removed by filtration to obtain the extract. Subsequently, the extract is subjected to dilution, concentration (evaporation concentration, vacuum concentration, reduced pressure concentration, membrane concentration, freeze concentration, etc.), drying (heat drying, freeze drying, spray drying, etc.), and purification (purification by activated carbon treatment, resin adsorption treatment, ion exchange resin treatment, liquid-liquid countercurrent partitioning, etc.) according to conventional methods to obtain an extract containing a high concentration of polyphenol components.

[0042] Furthermore, when extraction is performed by supercritical fluid extraction, the supercritical fluid used is not particularly limited, but examples include carbon dioxide and nitrogen. One of these may be used alone, or two or more may be used in combination. Of these, carbon dioxide is particularly preferred because it allows for easier extraction of skin-beautifying active ingredients. The extraction method at this time may be carried out by known methods. After that, the extract is subjected to treatments such as dilution, concentration, drying, and purification according to conventional methods to obtain an extract containing a high concentration of skin-beautifying active ingredients.

[0043] In the extraction method described above, each extract may be extracted individually, or multiple extracts may be extracted together from a mixed raw material consisting of two or more plant-based raw materials. From the viewpoint of efficiently extracting skin-beautifying active ingredients, it is preferable to employ an extraction method appropriate for each plant-based raw material.

[0044] The peeling gel cosmetic composition of the present invention preferably contains citric acid. Citric acid balances the pH of the skin and maintains a healthy state. From this viewpoint, the citric acid content is preferably 0.01% by mass or more, more preferably 0.05% by mass or more, preferably 2.0% by mass or less, and more preferably 1.0% by mass or less.

[0045] The peeling gel cosmetic composition of the present invention preferably contains sodium citrate. Sodium citrate, together with citric acid, stabilizes the pH of the composition and improves the feel of use. From this viewpoint, the sodium citrate content is preferably 0.001% by mass or more, more preferably 0.01% by mass or more, preferably 1.0% by mass or less, and more preferably 0.5% by mass or less.

[0046] The peeling gel cosmetic composition of the present invention preferably contains propanediol. Propanediol is a naturally derived moisturizing ingredient that protects the skin from dryness and maintains moisture even during peeling. From this viewpoint, the propanediol content is preferably 10% by mass or more, more preferably 15% by mass or more, preferably 30% by mass or less, and more preferably 25% by mass or less.

[0047] The peeling gel cosmetic composition of the present invention preferably contains human oligopeptide-1. The inclusion of human oligopeptide-1 enhances cell proliferation. Human oligopeptide-1 is preferably excipient-formed. For example, mannitol is a preferred excipient.

[0048] The dextrin, human oligopeptide-1, mannitol, citric acid, sodium citrate, propanediol, and ethanol used in this invention are preferably all naturally derived raw materials that comply with ISO 16128 standards.

[0049] The peeling gel cosmetic composition of the present invention contains water as a remainder. As the water, tap water, purified water (distilled water, deionized water, etc.), mineral water, alkaline ionized water, etc. can be used. The water is a naturally derived ingredient. The water content as a remainder is preferably 60% by mass or more, more preferably 65% ​​or more, preferably 85% or less, and more preferably 80% or less. [Examples]
