Description

  The present invention relates to an aqueous cleansing cosmetic.

  In recent years, the evolution of makeup technology has diversified from simple light makeup to makeup that is highly resistant to sweat and oil. In addition, the use of makeup cleansing has been subdivided due to the advancement of women in society and the diversification of lifestyles. Therefore, there are various cleansing agent types such as a conventional cold cream, a gel type, a lotion type and a milk type, and an oil type having a high cleansing power for oily makeup. In addition, recently, a liquid type (for example, see Patent Documents 1 to 3) in which cleansing power is improved by using a bicontinuous phase (isotropic surfactant continuous phase) has been attracting attention.

  Lotion-type cleansing cosmetics have been in constant demand from the past due to their fresh and non-sticky feeling and the convenience of simply impregnating and wiping cotton or nonwoven fabric. However, in skin lotion type cleansing cosmetics, blending oily ingredients such as oils and low-polarity surfactants to increase cleansing power makes transparent dissolution difficult, resulting in poor visual aesthetics and problems with stability. was there.

  Recently, sheet-type cleansing cosmetics (for example, see Patent Documents 4 and 5) in which a cleansing liquid is impregnated into a highly convenient non-woven fabric have high needs. However, it has been limited to light makeup users because eye makeup with a high waterproof property and heavy makeup, which are recent trends, cannot be removed sufficiently.

Therefore, it contains a silicone oil, a nonionic surfactant having a specific HLB value, an anionic surfactant, and a polymer thickener as a sheet-type cleansing cosmetic for heavy makeup. A sheet-like cleaning agent (see Patent Document 6) obtained by impregnating a nonwoven fabric with an oil-in-water emulsion cleaning composition having an emulsified particle size, comprising fibers having a cellulose content of 70% by mass or more, and a density Is a sheet-like cleansing material obtained by impregnating a non-woven fabric having a water content of 0.15 to 0.3 g / cm ³ with an aqueous thickener, an oil with a boiling point of 160 to 300 ° C., and an oil-in-water emulsion composition containing water. (Refer to Patent Document 7), a surfactant having an HLB of 5 to 8, a surfactant having an HLB of 10 to 15 and an oil component having an IOB of 0.1 to 0.7, Patent (See Document 8).

  However, although wiping can be easily performed based on these attempts, there is a problem that the oily feeling peculiar after wiping remains and the refreshing feeling after wiping is inferior. In addition, there may be a problem that undesired irritation occurs when the agent is mixed into the ocular mucosa during cleansing.

JP 2007-320884 A Japanese Patent No. 4274491 JP 2008-266224 A Japanese Patent Laid-Open No. 11-49641 JP 2002-154926 A JP 2005-34394 A JP 2005-145872 A JP 2002-68936 A

  The present invention has been made in view of the above prior art, and is an aqueous cleansing cosmetic that does not irritate the eye mucous membrane, can easily remove oil and dirt such as makeup, and suppresses stickiness after wiping. It is an issue to provide.

That is, the present invention
[1] Contains (A) water, (B) glyceryl polyoxyethylene fatty acid, (C) diethoxyethyl succinate, (D) polyether-modified silicone, and (E) linear silicone and / or cyclic silicone. The content of the component (A) is 75 to 97% by mass, the content of the component (B) is 0.2 to 5% by mass, and the content of the component (C) is 0.2 to is 5 wt%, the content of component (D) is 0.2 to 3 wt%, (E) content of the component, 0.2 to 3% by mass Ru aqueous cleansing cosmetic composition,
[2] The aqueous cleansing cosmetic according to [1], wherein the polyoxyethylene fatty acid glyceryl is polyoxyethylene (capryl / capric acid) glyceryl and / or polyoxyethylene coconut oil fatty acid glyceryl,
[3] HLB of the polyether modified silicone, an aqueous cleansing cosmetic composition according to above, wherein the 4 to 8 [1] or [2], <br/> in parallel beauty is [4] Appearance Clear The aqueous cleansing cosmetic according to any one of [1] to [ 3 ], which is characterized in that it exists.

  The aqueous cleansing cosmetic of the present invention has no effect on the ocular mucosa, and can be easily removed even when it is oily and fat stains such as heavy makeup, and has an effect of suppressing the sticky feeling after wiping. Moreover, since the aqueous cleansing cosmetic composition of the present invention is excellent in formulation stability, it has an effect of maintaining a transparent appearance with high aesthetics.

  The aqueous cleansing cosmetic of the present invention comprises (A) water, (B) polyoxyethylene fatty acid glyceryl, (C) diethoxyethyl succinate, (D) polyether-modified silicone, and (E) linear silicone and / or Or it contains cyclic silicone.

  The water of component (A) is not particularly limited as long as it can be used as a cosmetic raw material, but purified water is usually used. Although content of (A) component in this invention will not be specifically limited if a desired effect is provided, From a viewpoint made into aqueous | water-based, 70-97 mass% is preferable in cosmetics, More preferably, 75- 97% by mass. The reason is that when the amount is less than 70% by mass, a sticky feeling is generated and the feeling of use is inferior, and when the amount exceeds 97% by mass, a sufficient cleansing effect cannot be obtained.

  Examples of the fatty acid part of component (B) include caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, and the like. Examples thereof include oxyethylene fatty acid monoglyceryl and / or polyoxyethylene fatty acid diglyceryl. One of these components may be used alone, or two or more thereof may be used in appropriate combination. The number of added moles of ethylene oxide polymerized to these components is not particularly limited, but is preferably 2 to 50, more preferably 4 to 50 from the viewpoint of oily soil removal, water solubility and safety. 20.

  As a suitable component (B), it is preferable to use polyoxyethylene fatty acid monoglyceryl having 8 to 16 carbon atoms from the viewpoint of exerting a good cleansing power without irritation to the ocular mucosa. It is more preferable to use (capryl / capric acid) glyceryl and polyoxyethylene coconut oil fatty acid glyceryl.

  In addition, a commercial item can be used for (B) component as it is. Specifically, as polyoxyethylene (capryl / capric acid) glyceryl, for example, CETIOL HE810 (trade name, manufactured by Cognis Japan), Softiggen 767 (trade name, manufactured by Sasol), L. A. S (trade name, manufactured by Gatefosse) can be exemplified. Moreover, as polyoxyethylene coconut oil fatty acid glyceryl, for example, CETIOL HE (trade name, manufactured by Cognis Japan Co., Ltd.), M Fine Oil COG-7M (trade name, manufactured by Miyoshi Oil & Fats Co., Ltd.), Glycerox HE (trade name, Croda) (Manufactured by Japan Co., Ltd.).

  The content of the component (B) is not particularly limited as long as a desired effect is imparted, but usually 0.1 to 8% by mass is preferable in the cosmetic from the viewpoint of imparting an excellent cleansing effect. More preferably, it is 0.2-5 mass% or less. The reason is that if it is less than 0.1% by mass, an excellent cleansing effect cannot be obtained, and if it exceeds 8% by mass, ocular mucosal irritation is caused.

  The content of component (C) diethoxyethyl succinate is not particularly limited as long as a desired effect is imparted. However, from the viewpoint of imparting a desired cleansing power, usually 0.1 to 8 mass% is preferable, More preferably, it is 0.2-5 mass%. The reason is that if it is less than 0.1% by mass, a desired cleansing force cannot be imparted, and if it exceeds 8% by mass, a sticky feeling will occur after wiping.

  The HLB of the polyether-modified silicone as the component (D) is not particularly limited as long as a desired effect is imparted, but is preferably 4 to 8, more preferably 4 to 6. The reason for this is that if the HLB is less than 4, the solubility in the system is low, resulting in white turbidity, and a transparent appearance with high aesthetics cannot be maintained. This is because the stability is impaired.

  Examples of the polyether group of the polyether-modified silicone include a polyoxyethylene group, a polyoxypropylene group, and a polyoxybutylene group. In the present invention, either a linear block copolymer in which polyether and polysiloxane are alternately bonded in the molecule or a side chain modified type in which a polyether group is bonded to a side chain of polysiloxane can be used. However, it is more preferable to use a side chain-modified type from the viewpoint of maintaining the stability of the system. In addition, the molecular weight of the polyether-modified silicone is not particularly limited.

  In addition, (D) component can use a commercial item as it is. Specifically, SH3773M (HLB = 8, PEG-12 dimethicone; manufactured by Toray Dow Corning), SH3775M (HLB = 5, PEG-12 dimethicone; manufactured by Toray Dow Corning), SH3749 (HLB = 8, PEG) / PPG-20 / 20 dimethicone; manufactured by Toray Dow Corning), SS2910 (HLB = 4, PEG-10 dimethicone; manufactured by Toray Dow Corning), BY25-339 (HLB = 8.5, PEG / PPG-30) / 10 dimethicone; manufactured by Toray Dow Corning), KF-6012 (HLB = 7, PEG / PPG-20 / 22 butyl ether dimethicone; manufactured by Shin-Etsu Chemical), KF-6015 (HLB = 4.5, PEG-12 dimethicone) Manufactured by Shin-Etsu Chemical Co., Ltd.), KF-6016 (HLB = 4.5, PEG-9 methyl ether) Meticon; manufactured by Shin-Etsu Chemical Co., Ltd.), KF-6017 (HLB = 4.5, PEG-10 dimethicone; manufactured by Shin-Etsu Chemical Co., Ltd.), KF-6028 (HLB = 4, PEG-9 polydimethylsiloxyethyl dimethicone; manufactured by Shin-Etsu Chemical Co., Ltd.) ), SILSOFT 305 (HLB = 5-8, PEG / PPG-5 / 3 dimethicone; manufactured by Momentive Performance Materials Japan), SILSOFT 805 (HLB = 5-8 PEG-8 dimethicone; Momentive Performance Materials Japan) SILSOFT 810 (HLB = 5-8 PEG-8 dimethicone; manufactured by Momentive Performance Materials Japan), etc., among which SH3775M, SS2910, and KF-6017 are particularly preferable.

  (D) Content of a component becomes like this. Preferably it is 0.1-5 mass%, More preferably, it is 0.2-3 mass%. The reason is that if it is less than 0.1% by mass, the solubilization of the silicone oil is insufficient, and if it exceeds 5% by mass, a sticky feeling is produced after use, which is not preferable.

  Examples of the component (E) include linear silicones such as dimethylpolysiloxane (dimethylsilicone oil), phenylmethylpolysiloxane (phenyl-modified silicone oil), and highly polymerized methylpolysiloxane; octamethylcyclotetrasiloxane, decamethylcyclo Examples thereof include cyclic silicones such as pentasiloxane and dodecamethylcyclohexasiloxane, and it is more preferable to use dimethylpolysiloxane, octamethylcyclotetrasiloxane, and decamethylcyclopentasiloxane from the viewpoint of usability. These (E) components may be used individually by 1 type, and can also be used in combination of 2 or more types as appropriate.

  (E) Content of a component becomes like this. Preferably it is 0.1-5 mass%, More preferably, it is 0.2-3 mass%. The reason is that if it is less than 0.1% by mass, the desired cleansing power cannot be obtained, and if it exceeds 5% by mass, the stability of the system is impaired and the skin feel after use is unfavorable. Because.

  In the aqueous cleansing cosmetic of the present invention, within the range not impairing the effects of the present invention, in addition to the above-described components, components commonly used in cosmetics, such as ultraviolet absorbers, powders, antioxidants, Additives such as preservatives, fragrances, coloring agents, chelating agents, refreshing agents, thickeners, plant extracts, vitamins, neutralizing agents, amino acids, pH adjusters, whitening agents, anti-inflammatory agents, fungicides, etc. It can mix | blend suitably according to the use and the objective.

  Moreover, it is preferable that the aqueous cleansing cosmetic of the present invention does not substantially contain ethanol. As a result, it is possible to reduce irritation to the skin and mucous membranes without rinsing with lukewarm water and post-face washing after the treatment. In the present invention, “substantially does not contain ethanol” means “does not contain ethanol separately”, and does not exclude a trace amount of ethanol contained in each compounding component. .

  The aqueous cleansing cosmetic of the present invention can be used without being washed away after wiping. This is because the skin is prevented from being dried and the moisturizing feeling can be maintained by not washing it off. In the case of washing away, it is preferable to wash away with water or hot water, and it is preferable not to wash it twice with an aqueous facial cleanser. More preferable usage examples include a method of impregnating a cotton or non-woven fabric with an aqueous cleansing cosmetic and performing treatment on the application site, or a method of wiping the aqueous cleansing cosmetic on the application site and then wiping with cotton or non-woven fabric. can do.

  As described above, the water-based cleansing cosmetic of the present invention not only has an excellent effect of removing oil and fat stains such as makeup, but also has an excellent effect on stability, and thus maintains a transparent appearance with high aesthetics. It is something that can be done. Here, the term “transparent” refers to a degree of transparency that allows the opposite shore to be seen through the glass when the contents are put in a circular glass container having a diameter of 5 cm.

  EXAMPLES Hereinafter, although this invention is demonstrated further in detail based on an Example, this invention is not limited only to these Examples. The blending amount represents “% by mass” unless otherwise specified. In the table, the number of added moles of polyoxyethylene is shown in parentheses.

(Sample preparation 1)
According to the composition described in Tables 1 to 3, each of the aqueous cleansing cosmetics of Examples 1 to 5 and Comparative Examples 1 to 8 was prepared according to a conventional method and subjected to the following evaluation. The results are shown in Tables 1 to 3, respectively.
In addition, all evaluation was implemented on the constant conditions of constant temperature and humidity of 23 degreeC and 60% of humidity.

(Test Example 1: Evaluation of makeup dirt (foundation) removal)
Black urethane cloth (trade name: Supplar, manufactured by Idemitsu Petrochemical Co., Ltd.) 2 cm x 10 cm, uniformly apply 0.3 g of liquid foundation (trade name: Diaferne Plus Creme Tandosur <Natural>, manufactured by Pierce Lab.) It was extended for one day and dried. Next, 3 mL of the aqueous cleansing cosmetic obtained in each Example and each Comparative Example was impregnated into cotton, and a load of 25 gf was applied to the sample-containing cotton using a friction tester (KES-SE, manufactured by Kato Tech Co., Ltd.). The urethane cloth was pulled over 10 cm.

In addition, evaluation evaluated the area value from which the foundation | substrate was removed in the urethane cloth by image analysis, calculated the removal rate by the following formula, and evaluated it according to the following evaluation criteria.
Removal rate (%) = (Area value from which foundation is removed / Area value of urethane cloth) × 100

<Evaluation criteria for removing makeup dirt (foundation)>
◎: Removal rate is 80% or more ○: Removal rate is 50% or more and less than 80% Δ: Removal rate is 20% or more and less than 50% ×: Removal rate is less than 20%

(Test Example 2: Evaluation of makeup stain (mascara) removal)
20 female panelists who regularly use waterproof mascara have their water-based cleansing cosmetics obtained in each of the examples and comparative examples used to actually wipe off the mascara. Sensory evaluation was performed.

<Evaluation criteria for removing makeup stains (mascara)>
◎: Reply if 16 or more out of 20 people are excellent in removal effect ○: Reply if 11-15 out of 20 people are excellent in removal effect △: Reply if 6-10 out of 20 people are excellent in removal effect ×: 20 5 or less of the names responded that they had excellent removal effects

(Test Example 3: Evaluation of stimulation)
Twenty female evaluation panels with makeup were made to impregnate the cotton with the water-based cleansing cosmetics obtained in each of the examples and comparative examples, and used to actually wipe off the makeup. The "mucosal irritation" was sensory evaluated according to the following evaluation criteria. Further, “eye mucous membrane irritation” refers to “feeling tingling” or “tingling sensation” that is felt when the eyes are rubbed into the eyes during cleansing.

<Evaluation criteria for ocular mucosal irritation>
◎: More than 16 out of 20 responded that there was no ocular mucosal stimulation ○: 11-15 out of 20 responded that there was no ocular mucosal stimulation △: 6-10 out of 20 responded that there was no ocular mucosal irritation ×: 5 or less of 20 responded that there was no ocular mucosal irritation

(Test Example 4: Evaluation of feeling of use)
The 20 panelists evaluated the stickiness immediately after cleansing in Test Example 2 and the moist feeling of the skin after 1 hour according to the following evaluation criteria.

<Evaluation criteria for stickiness>
◎: 16 or more of 20 people answered that there was no stickiness ○: 11-15 of 20 people answered that there was no stickiness △: 6-10 of 20 people answered that they did not feel sticky ×: 20 5 or less people answered that there was no stickiness

(Test Example 5: Appearance evaluation)
The prepared aqueous cleansing cosmetic was filled in a glass tube having a diameter of 3 cm and a volume of 50 ml, and the appearance after 1 hour was observed.

<Evaluation criteria for appearance>
○: Transparent Δ: Slightly cloudy ×: Cloudy, precipitated or separated

  From the results of Tables 1 to 3, although the water-based cleansing cosmetics of each example have a remarkably superior effect on the removal effect of the foundation and the waterproof mascara as compared with those of the respective comparative examples. No ocular mucosal irritation or stickiness. Moreover, since the water-based cleansing cosmetic of each Example is excellent in formulation stability, it turns out that the transparent appearance with high aesthetics is maintained.

  On the other hand, from Example 1, Comparative Example 1 in which the component (B) is simply not blended, Comparative Example 3 in which the component (D) is simply not blended from Example 3, and the component (D) from Example 3 are the same. The aqueous cleansing cosmetics of Comparative Examples 4 and 5 replaced with another amount of the silicone-based surfactant cannot obtain a stable product with a poor system balance. Therefore, it can be seen that the sticky feeling is high and the effect of removing makeup stains is low. Further, from Example 2, Comparative Example 2 in which the component (C) is simply not blended, Comparative Example 6 in which the component (E) is simply not blended from Example 4 and the component (B) from Example 5 to another interface are separated. The aqueous cleansing cosmetics of Comparative Examples 7 and 8 replaced with an active agent have a low effect of removing makeup stains especially on mascara, have a sticky feel, and cause undesired irritation to the ocular mucosa. I understand.
