Description

  The present invention relates to a cleansing composition for removing makeup, and more particularly to a cleansing composition capable of removing both oily mascara and film-forming mascara.

  As a technique for removing makeup, it is known to use an aqueous solution of a surfactant or to use an oil in the form of a gel, cream or oil. Among makeup cosmetics, mascara that is relatively difficult to remove includes aqueous mascara containing a water-soluble polymer for curl retention effect and the like, and oil-based mascara that does not easily lose makeup against sweat or water. However, conventional surfactant aqueous solutions can quickly remove aqueous mascara that is easily dissolved or dispersed in water but cannot remove oily mascara, and oil-based cleansing agents can remove oily mascara but cannot remove aqueous mascara. There was a problem. Further, when the surfactant aqueous solution and the oil agent coexist, there is a problem that the oil agent is emulsified by the surfactant and the oil agent cannot effectively act on the oily makeup stain.

  With the spread of mascara in recent years, film-forming mascara utilizing the film-forming ability of latex polymer, especially mascara containing an alkyl acrylate copolymer with excellent film-forming ability, has increased in both oiliness and aqueous properties. ing. Latex polymer is a polymer in which a water-insoluble polymer is present in water as an emulsion.Evaporation of water creates a strong bond between latex polymer particles and forms a film. Does not disperse and dissolves quickly in oils. For this reason, there is a problem that the film once formed cannot be effectively removed by a conventional makeup removing technique using a surfactant aqueous solution or an oil agent.

  Patent Document 1 discloses an eye makeup remover in which isoparaffin is emulsified in water with a polyoxyethylene alkyl ether-based surfactant for the purpose of removing oily and film-formed eye makeup cosmetics. However, in this method, the cleaning power was insufficient for a mascara containing a large amount of an alkyl acrylate copolymer that forms a strong film.

  As a technique for removing makeup without using other general surfactants, Patent Document 2 discloses a non-emulsifying surfactant coexisting with an emulsion containing an acrylic acid / alkyl acrylate copolymer type emulsifier, an oil agent, and water. Patent Document 3 discloses a cleansing composition in which oil and water coexist in a large amount of a polyol as a humectant. Patent Document 4 discloses a makeup remover in which low-boiling point isoparaffin or low-boiling point silicone oil is dispersed in an aqueous phase with a polyacrylic thickener, and Patent Document 5 discloses a water-soluble polysaccharide, A makeup remover containing a boiling oil agent and water as essential components is disclosed. However, they can remove oily or aqueous mascara, but cannot effectively remove film-forming mascara.

  Patent Document 6 discloses a composition for cleansing tissue comprising a mixture of polyalkylene glycol, ethanol, a water-soluble polyhydric alcohol, a surfactant and water, and Patent Document 7 discloses polyoxyethylene methyl. A composition for removing makeup cosmetics comprising one or more selected from glucoside and polyoxypropylene methyl glucoside and a nonionic surfactant having an HLB of 10 or more is disclosed. However, they can remove aqueous mascara but cannot remove oily mascara and cannot effectively remove film-forming mascara.

  Therefore, according to the prior art, a mascara blended with a latex polymer, particularly an alkyl acrylate copolymer that forms a strong film, even though common makeup such as foundation, lipstick, and ordinary aqueous or oily mascara can be removed. Was not able to drop enough.

JP-A-5-163116 Japanese Patent Publication No. 11-503461 JP-A-9-48706 JP-A-62-135406 JP-A-9-110638 JP-A-2-104511 JP-A-9-143028

  It is an object of the present invention to remove not only ordinary makeup, but also oil-based mascara and film-forming mascara, and furthermore, an alkyl acrylate copolymer that forms a particularly strong film among latex polymers that are film-forming agents. An object of the present invention is to provide a cleansing composition having an excellent feeling in use, which can effectively remove mascara containing a large amount of coalescence and can sufficiently remove all makeup cosmetics.

  Makeup cosmetics, such as mascara, which are difficult to remove consist of a film-forming polymer, an oil-soluble component and a water-soluble component fixed thereto. The present inventors have found that a water-soluble compound having a polyoxypropylene structure having 3 or more moles of propylene oxide added and not having an alkyl group having 4 or more carbon atoms and / or having no polyoxyethylene structure is contained in an aqueous phase in an amount of 1%. A water phase containing 水 25% by mass and an oil phase which is liquid at 30 ° C. are combined in a specific ratio, and the cleansing composition containing more than 10% by mass of water in the total composition is the strongest among general makeup stains. It has been found that it is possible to remove oily mascara, which is a very oily stain, and mascara containing a large amount of an alkyl acrylate copolymer, and to solve the above problems.

  The cleansing composition according to the present invention can remove not only ordinary makeup stains but also oily mascara and film-forming mascara, and an alkyl acrylate that forms a particularly strong film among latex polymers that are film-forming agents. It is a cleansing composition that can effectively remove mascara containing a large amount of a copolymer, can remove all makeup stains, and is excellent in usability.

The cleansing composition of the present invention comprises the following components (A) and (B):
(A) A water-soluble compound (a) having a polyoxypropylene structure having 3 or more moles of propylene oxide added and having no alkyl group having 4 or more carbon atoms and / or no polyoxyethylene structure is added to the aqueous phase by adding 1 Aqueous phase containing ~ 25% by mass,
(B) an oil phase liquid at 30 ° C.
Wherein the weight ratio (A) :( B) of the component (A) and the component (B) is 97: 3 to 40:60, and water is more than 10% by mass in the total composition. It is a cleansing composition that contains a lot.

  The component (A) used in the present invention has a polyoxypropylene structure having 3 or more moles of propylene oxide added, an alkyl group having 4 or more carbon atoms (hereinafter abbreviated as “C”) and / or a polyoxyethylene structure. An aqueous phase containing 1 to 25% by mass of a water-soluble compound (a) having no (hereinafter sometimes referred to as “compound (a)”) is selected. Such an aqueous phase (A) has a low detergency for general oily makeup stains, but has a certain detergency for a polymer film. By combining the aqueous phase (A) with the oil phase (B) having excellent detergency against oily makeup stains and having a slight detergency against the polymer coating at a specific ratio, the oil phase It has high detergency against mascara and other common makeup stains. Further, the effect of removing film-forming mascara, particularly mascara containing a large amount of an alkyl acrylate copolymer that forms a strong film, is significantly improved.

The compound (a) contained in the aqueous phase (A) has a polyoxypropylene structure in which the number of moles of propylene oxide added is 3 or more from the viewpoint of detergency against the polymer film. Since the compound (a) does not have a C4 or higher alkyl group, it does not behave like a surfactant, and hardly forms micelles in water, and thus easily enters a fine portion of a polymer film. Furthermore, the polyoxypropylene structure acts on the strong bonds between the latex polymer particles to promote the re-dispersion of the polymer film in water, and thus is presumed to be excellent in removing the film-forming mascara. When it has, distribution to the aqueous phase is increased, and the washing effect is reduced.
Further, the compound (a) has appropriate water solubility. The term "water-soluble" as used herein means having a solubility of 1% by mass or more in water at 25 ° C.

As the compound (a) contained in the aqueous phase (A) of the present invention, a hydroxyl group, a glyceryl group, a polyglyceryl group, or a hydrophilic group such as a sugar residue is bonded to a polyoxypropylene structure having 3 or more moles of propylene oxide added. It is preferable that the compound is a modified compound.
Specific examples of the compound (a) include polyoxypropylene diglyceryl ether, polyoxypropylene glyceryl ether, polyoxypropylene methyl glucoside, and polypropylene glycol.

  Polyoxypropylene diglyceryl ether is obtained by adding propylene oxide to diglycerin. Among them, the addition mole number of propylene oxide is preferably 4 to 24 moles, and more preferably 6 to 18 moles from the viewpoint of detergency for the polymer film. Polyoxypropylene glyceryl ether is obtained by adding propylene oxide to glycerin. Among these, the number of moles of propylene oxide added is preferably from 8 to 24 moles, and more preferably from 8 to 16 moles, from the viewpoint of detergency for the polymer film. Polyoxypropylene methyl glucoside is obtained by adding propylene oxide to methyl glucoside. Among these, the number of moles of propylene oxide added is preferably 5 to 25 mol, and more preferably 10 to 20 mol, from the viewpoint of detergency for the polymer film. From the viewpoint of the detergency of the polymer film, the number of moles of propylene oxide added to the polypropylene glycol is preferably 5 to 20 mol, and more preferably 7 to 16 mol.

  Among them, polyoxypropylene diglyceryl ether and polyoxypropylene glyceryl ether have the effect of improving the skin familiarity of the composition, and are not sticky after use, and are preferable because they give a moist feeling, and polyoxypropylene diglyceryl ether is preferred. Particularly preferred.

  The compound (a) contained in the aqueous phase (A) can be used alone or in combination of two or more. The amount of the compound (a) in the aqueous phase (A) is 1% by mass or more based on the total amount of the aqueous phase (A), since sufficient detergency is obtained even for the film-forming mascara. The content is set to 25% by mass or less so as not to cause a residual feeling on the skin after that. From the balance between detergency and feeling of use, it is more preferably used in an amount of 3 to 20% by mass, particularly preferably 5 to 15% by mass, based on the total amount of the aqueous phase (A).

  Further, the water contained in the aqueous phase (A) must be contained in an amount of more than 10% by mass, preferably 30% by mass or more based on the total amount of the composition, from the viewpoints of sufficient detergency and good usability. And particularly preferably 50% by mass or more.

  The aqueous phase (A) contains the above compound (a) and water as main components, but may contain other water-soluble components. For example, the use feeling can be improved by including alcohols such as ethanol and polyol. In particular, the blending of ethanol is highly effective in improving the refreshing feeling, and the blending of 1,3-butylene glycol and glycerin is highly effective in improving the moist feeling.

  The component (B) used in the present invention is an oil phase that is liquid at 30 ° C. and has excellent detergency against oily mascara and general oily makeup stains. Also, it has a certain degree of dissolving power to the polymer film, though not so much as the component (A), and has some detergency. The oil phase having a low viscosity has high permeability to fine parts and high solubility of dirt, and thus has high detergency. Further, the feeling of use is good without a strong oily feeling.

  Therefore, it is preferable to use an oil phase having a viscosity of 10 mPa · s or less at 30 ° C. as the oil phase (B). The oil phase (B) may be used alone or in combination of two or more oil components. When two or more oil components are used as a mixture as the oil phase (B), even if an oil component that is not liquid at 30 ° C. alone or an oil component having a viscosity greater than 10 mPa · s at 30 ° C. is used, If the total viscosity of the mixture of two or more is not more than 10 mPa · s at 30 ° C., it can be suitably used. Here, the viscosity can be measured by a BM type viscometer (for example, manufactured by Tokimec) (measurement conditions: rotor No. 1, 60 rpm).

  Specific examples of the oil component having a viscosity of 10 mPa · s or less at 30 ° C. include liquid isoparaffin, alkyl 1,3-dimethylbutyl ether (JP-A-9-87223), cetyl 2-ethylhexanoate, and myristic acid. Examples include isopropyl, isopropyl palmitate, isononyl isononanoate, isotridecyl isononanoate, diisobutyl adipate, diisopropyl adipate, octamethyltrisiloxane, decamethylcyclopentasiloxane, dodecamethylpentasiloxane, octamethylcyclotetrasiloxane, and the like.

  Among them, an oil component having a molecular weight of 300 or less is more preferable because it has a high detergency and has an excellent use feeling with little oiliness after use. Specific examples include light liquid isoparaffin, isopropyl myristate, isopropyl palmitate, isononyl isononanoate, diisobutyl adipate, diisopropyl adipate, octamethyltrisiloxane, octamethylcyclotetrasiloxane, and the like. Particularly preferred is light liquid isoparaffin having a boiling point of 160 ° C. to 300 ° C. at 1013.25 hPa, from the viewpoints of detergency against the polymer film and excellent refreshing usability, and isododecane is particularly preferred.

  From the viewpoint of improvement in detergency, light liquid isoparaffin having a boiling point of 160 ° C. to 300 ° C. at 1013.25 hPa, more preferably isododecane, and the concentration in the oil phase (B) is 50% by mass or more, preferably 80% by mass or more. It is preferable to contain them so that

Light liquid isoparaffin is generally a mixture of branched hydrocarbons having 8 to 18 carbon atoms and has a unique odor when it contains low molecular weight hydrocarbons. Since such an odor may not be preferred by a user, it is preferable that the odor does not contain a low molecular weight component having 8 to 9 carbon atoms as much as possible. On the other hand, when a large amount of a hydrocarbon having 16 to 18 carbon atoms is contained, the detergency is poor, and the oily feeling after use tends to be strong. From such a point, it is preferable to contain a large amount of isoparaffinic hydrocarbon having 10 to 15 carbon atoms. Above all, it is preferable to contain a large amount of isododecane having 12 carbon atoms in view of a balance between odor, feeling of use, and cleansing performance.
Light liquid isoparaffins are trade names Marcazole R (Maruzen Petrochemical), IP Solvents 1620, 2028 (above, Idemitsu Petrochemical), Isopar L, Isopar H (above, Exxon Chemical), Isosol 300, 400 (above, New Japan) Petrochemicals) and the like, but Marcazole R is particularly preferably used because it contains isododecane with high purity.

  The oil phase (B) has a mass ratio (A) :( B) of 97: 3 to the aqueous phase (A) from the viewpoint that a sufficient detergency and an oily feeling are not strengthened and a good feeling in use is obtained. The content is 40:60, preferably 90:10 to 70:30, particularly preferably 88:12 to 75:25.

  The mixture of the water phase (A) and the oil phase (B) separates into two phases when left to stand. However, the mixture is temporarily homogenized by shaking, and is wiped off with makeup such as cotton for makeup. Or, it can be picked up as it is, and used after being applied to dirt.

  When only the water phase (A) and the oil phase (B) are easily separated into two phases in a short time, the cleansing composition of the present invention contains an aqueous thickener as the component (C) in order to further facilitate use. It can be contained. By containing the water-based thickener, a uniform state is maintained when the composition is shaken and the viscosity is increased to make it easier to use, so that the familiarity with the skin and the massage properties are improved.

  Specific examples of the water-based thickener include the following water-soluble polymers. Examples of natural water-soluble polymers include, for example, gum arabic, tragacanth, galactan, guar gum, carob gum, karaya gum, carrageenan, pectin, agar, quince seed (quince), alge colloid (cassow extract), starch (rice, corn, potato, Wheat), plant polymers such as glycyrrhizic acid, microbial polymers such as xanthan gum, dextran, succinoglucan and pullulan, and animal polymers such as collagen, casein, albumin and gelatin. Examples of semi-synthetic water-soluble polymers include, for example, carboxymethyl starch, starch polymers such as methylhydroxypropyl starch, methylcellulose, nitrocellulose, ethylcellulose, methylhydroxypropylcellulose, hydroxyethylcellulose, cellulose sodium sulfate, hydroxypropylcellulose, Cellulose polymers such as sodium carboxymethylcellulose (CMC), and alginic acid polymers such as sodium alginate and propylene glycol alginate are exemplified. Examples of the synthetic water-soluble polymer include polyvinyl alcohol, polyvinyl methyl ether polymer, polyvinyl pyrrolidone, vinyl polymer such as carboxyvinyl polymer (CARBOPOL 940, 941; Noveon, Inc.), polyethylene glycol 20000, Polyoxyethylene polymers such as polyethylene glycol 6000 and polyethylene glycol 4000, copolymer polymers such as polyoxyethylene polyoxypropylene copolymer, and acrylic polymers such as sodium polyacrylate, polyethyl acrylate and polyacrylamide , Polyethyleneimine, cationic polymers and the like.

  In particular, when a water-based thickener having a hydrophobic part is used, the aqueous phase (A) is thickened, and the oil phase (B) is dispersed in an oil-in-water type, whereby an apparently uniform preparation can be obtained. It is possible. The term "water-based thickener having a hydrophobic part" as used herein refers to a water-soluble polymer having a C10 or more hydrophobic group in a side chain. When a water-based thickener having a hydrophobic portion is used, the hydrophobic portion interacts with the oil agent, so that the oil agent can be relatively stably held in water. However, as in the case of emulsification using a normal surfactant, Since the oil is not finely emulsified, the oil is easily released at the time of use, and the detergency is not impaired.

  Specific examples of such an emulsifying and dispersing water-based thickener include acrylic acid / alkyl methacrylate (C10-30) copolymer (manufactured by Noveon, Inc., trade names: PEMULEN TR-1, PEMULEN). TR-2, CARBOPOL ETD, etc.), and hydroxyethyl cellulose hydroxypropyl stearyl ether sodium hydroxypropyl sulfonate (JP-A-9-235301).

  The aqueous thickeners can be used alone or in combination of two or more. The content of the water-based thickener (C) is preferably 0.01 to 5% by mass, and more preferably 0.1 to 5% by mass based on the total amount of the composition from the viewpoint of ease of use, elongation on the skin, and lack of sliminess. It is preferably from 0.01 to 2% by mass, particularly preferably from 0.01 to 1% by mass.

  In addition, you may use the neutralizing agent for neutralizing the said water-based thickener and thickening as needed. Examples of the neutralizing agent include inorganic alkali agents such as sodium hydroxide and potassium hydroxide, basic amino acids such as L-arginine, amines such as triethanolamine, and ammonia. The amount of the neutralizing agent to be added may be determined depending on the type and amount of the aqueous thickener, and is preferably about 0.005 to 0.5% by mass based on the total amount of the composition. The neutralizing agent may be added by dissolving in water in advance or by directly mixing with the aqueous thickener.

The cleansing composition of the present invention can contain a surfactant as the component (D) as long as the effects of the present invention are not impaired. The addition of an appropriate amount of a surfactant stabilizes the emulsified state and improves the compatibility of the composition with the skin, but the surfactant coexists with the aqueous phase (A) and the oil phase (B). Since it is adsorbed and stabilized on the oil-water interface below, if a large amount is blended, the component (B) cannot effectively act on makeup stains. Therefore, it is preferable that the function of stabilizing the emulsification / dispersion is mainly obtained from the above-mentioned aqueous thickener.
(D) In order to use the surfactant within a range that does not hinder the action of the aqueous phase (A) and the oil phase (B), the content of the surfactant is 2% by mass or less based on the total amount of the composition. It is more preferably 0.5% by mass or less, particularly preferably less than 0.05% by mass.

  Surfactants can be used alone or in combination of two or more. As a specific example, from the viewpoint of mildness to the skin, polyoxyethylene alkyl ethers and sucrose fatty acid esters, fatty acid monoglycerides, sorbitan fatty acid ester and its polyoxyalkylene addition type, polyoxyethylene hardened castor oil and its Fatty acid esters, polyoxyalkylene fatty acid esters and the like can be mentioned.

  In addition, the cleansing composition of the present invention, in addition to the above components, components used in ordinary cleaning compositions, such as humectants, oil gelling agents, ultraviolet absorbers, fragrances, pigments, dyes, salts, and stabilizers Various additives such as preservatives, antioxidants, vitamins, proteins, conditioning agents and the like can be added within a qualitative and quantitative range that does not impair the objects and effects of the present invention.

  The cleansing composition of the present invention can be produced according to a conventional method using each of the above-mentioned materials, and can be in the form of a liquid type, a gel type, a cream type or a two-phase separation type.

  As a method of removing makeup using the cleansing composition of the present invention, a method of wiping the makeup on the skin by impregnating the composition as it is or after shaking to homogenize and then impregnating with a wiping medium, And apply it to the skin, apply it to make-up, wipe off with a wiping medium or rinse off. Here, examples of the wiping medium include cotton and tissue paper.

(Method of evaluating detergency)
For evaluation of detergency, oil-based mascara and a film-forming aqueous mascara containing a large amount of an alkyl acrylate copolymer were used.
A predetermined amount of mascara was uniformly applied on a slide glass in a circular shape having a diameter of 1.2 cm, and allowed to dry for 12 hours. 0.0070 g of Kanebo Testimo Mascara Effect (Carl Long) BK18 (trade name) is applied as a film-forming type aqueous mascara, and 0.0045 g of Kose Sports Beauty Fashio Power Stay Mascara (Carl Long) BK001 (trade name) is applied as an oily mascara. did. Due to the difference in liquid properties of each mascara, the amount of application when the mascara is uniformly applied over a certain area is different.

  The cleansing composition composed of the components (A) and (B) separates promptly even after mixing. Therefore, when evaluating the detergency, 3.8 g of the cleansing composition is added to 1 g of cotton, and the cotton is gently rubbed. After spreading the material over the entire cotton and making it uniform, apply the cotton to the mascara, gently press it for 5 seconds, and wipe it with a constant pressure (100 g / cm2) to determine the number of wipes required to remove the mascara. Each mascara was measured and evaluated according to the following criteria (Example 1, Comparative Examples 1 to 5).

<Evaluation criteria for detergency against film-forming aqueous mascara>
◎ 14 times or less ○ 15-19 times ○ △ 20-24 times △ 25-29 times × 30 times or more

<Evaluation criteria for detergency against oily mascara>
◎ 5 times or less ○ 6 to 10 times ○ △ 11 to 15 times 16 to 20 times × 21 times or more

  Further, as for the liquid-type cleansing composition homogenized using the component (C), 0.1 g of the cleansing composition is applied to a mascara that has been applied to a slide glass and dried as described above, and a film-forming type. For water-based mascara, 60 times, for oil-based mascara, 30 times, massage with a finger to float dirt, wipe off with tissue paper, and evaluate according to the following evaluation criteria (Examples 2 to 9, Comparative Examples 6 to 9) 11).

<Evaluation criteria for detergency for each mascara>
◎ The mascara has dropped enough.
○ Mascara is almost dropped.
○ △ Some mascara is left. Some mascara is not dropped.
× Mascara has not fallen.

(How to evaluate usability)
Ten expert panelists apply the appropriate amount of the cleansing composition evenly to the face, and have a feeling of use (good, sticky, slimy), "good", "somewhat good", "neither", "not very good", "good" The sensory evaluation was performed at five levels of "not available", and the evaluation was made according to the following criteria.

[Evaluation criteria]
◎; 9 or more out of 10 answered “good” or “somewhat good” ○; 7 to 8 out of 10 answered “good” or “somewhat good” △; 4 to 6 out of 10 Answered “good” or “somewhat good” ×; 3 or less out of 10 answered “good” or “somewhat good”

(Example 1, Comparative Examples 1 to 5)
Each component was mixed with the composition shown in Table 1 to produce a cleansing composition, and when the cleansing composition was used, the detergency against a film-forming type aqueous mascara, the detergency against an oily mascara, and the feeling of use were evaluated. . Table 1 shows the evaluation results of the cleansing compositions.

  From the results shown in Table 1, Example 1 shows that the two components (A) and (B) were blended in the proportions specified by the present invention, and a coating film in which a large amount of the alkyl acrylate copolymer was blended. Both the formation type mascara and the oily mascara could be effectively removed, and the feeling in use was excellent. On the other hand, in the composition not containing the compound (a) in the component (A) (Comparative Example 1) or containing the compound (a) in an aqueous phase concentration of 25% by mass or more (Comparative Example 2), the oily mascara can be removed. However, the detergency against the film-forming mascara was inferior to that of the examples. Further, the composition containing no component (B) (Comparative Example 3) has a detergency for film-forming mascara, but has insufficient detergency for oily mascara. It has been clarified that, by combining the components, not only the detergency for oily mascara but also the detergency for a film-forming mascara containing a large amount of an alkyl acrylate copolymer is significantly improved. The composition containing both the component (A) and the component (B), but the mass ratio (A) :( B) is out of the range of 97: 3 to 40:60 (Comparative Example 4), is an oily mascara and a coating. Although both of the formation type mascara can be effectively removed, the feeling of use was inferior to the examples because of a strong oily feeling. When the concentration of water in the composition was 10% by mass or less (Comparative Example 5), the film-forming mascara could not be removed, and the feeling of use was inferior to the examples because of the stickiness and stickiness.

(Examples 2 to 9, Comparative Examples 6 and 7)
As a composition further containing the component (C) of the present invention, each component is mixed with the composition shown in Table 2 to produce a cleansing composition, and washing of the film-forming aqueous mascara when the cleansing composition is used. The power, detergency against oily mascara, and feeling of use were evaluated. Table 2 shows the evaluation results of each cleansing composition.

  In Examples 2 to 9, which are liquid cleansing compositions to which an aqueous thickener having a hydrophobized part is added as the component (C), the components (A) and (B) become uniform emulsions. It was possible to evaluate the detergency by directly applying without using. From the results shown in Table 2, in Examples 2 to 9, by blending the two components (A) and (B) at the ratio specified by the present invention, a large amount of the alkyl acrylate copolymer was blended. It was clarified that both the film-forming mascara and the oil-based mascara could be effectively removed, and the feeling of use was excellent.

Example 5 in which polyoxypropylene (10) glyceryl ether was blended as compound (a) contained in component (A), and Examples 6 to 9 in which polyoxypropylene (9) diglyceryl ether was blended, Better feeling than in Examples 2 to 4 in which the compound (a) was blended. Further, in Examples 6 to 9 in which polyoxypropylene (9) diglyceryl ether was blended, the feeling of use was particularly excellent, and a pleasant moist feeling was obtained.
On the other hand, Comparative Example 6, which contains a compound further having a C4 alkyl group and a polyoxyethylene structure together with the polyoxypropylene structure, had inferior detergency to both the film-forming mascara and the oily mascara to the examples. . In Comparative Example 7 in which polypropylene glycol (34), which was not water-soluble because of the large number of moles of propylene oxide added, had a detergency against the film-forming mascara, which was inferior to that of the examples, even though oily mascara could be removed. became.

In addition, Example 7 in which glycerin was blended had a moist and excellent use feeling compared to Example 6, and Example 8 in which ethanol was blended had a refreshing and excellent use feeling compared to Example 6. .
Further, in Example 3, in which isododecane was blended in an amount of 50% by mass or more in the oil phase (B), compared to Example 2, in which isododecane was not blended at all, both the film-forming mascara and the oily mascara were washed. It was an excellent one. Further, in Example 4 in which isododecane was blended in the component (B) in an amount of 80% by mass or more, the detergency of the oil-based mascara was increased as compared with Example 3.

  In Examples 6 to 8 in which the surfactant (D) was incorporated in an amount of 0.045% by mass and in Example 9 in which 2% by mass was incorporated, the detergency against both the film-forming mascara and the oily mascara was recognized. In addition to that, the skin became familiar. In particular, in Examples 6 to 8 in which the surfactant was blended at 0.045% by mass, good detergency was obtained in both the film-forming mascara and the oily mascara as compared with Example 9 in which 2% by mass was blended. Was done.

(Comparative Example 8)
Each component was mixed with the composition shown in Table 3 to produce a cleansing composition, and the detergency against mascara was evaluated. Table 3 shows the evaluation results.

  A composition containing polyoxypropylene methyl glucoside and a nonionic surfactant (hexaglyceryl monomyristate) having an HLB of 10 or more can be obtained by the method described in Patent Document 7 (Japanese Patent Application Laid-Open No. 9-143028). Although corresponding to the example, it has been found that although it has a detergency to a film forming type mascara to a certain extent, its detergency to oily mascara is inferior.

(Comparative Example 9)
Each component was mixed with the composition shown in Table 4 to produce a cleansing composition, and the detergency against mascara was evaluated. Table 4 shows the evaluation results.

  A composition containing a polyalkylene glycol, ethanol, a water-soluble polyhydric alcohol, a surfactant and water corresponds to the example of Patent Document 6 (Japanese Patent Application Laid-Open No. 2-104511). Although it has some detergency, it has been found that the detergency for oily mascara is inferior.

(Comparative Example 10)
The components shown in Table 5 were mixed to produce a cleansing composition, and the detergency against mascara was evaluated. Table 5 shows the evaluation results.

  A non-emulsifiable surfactant (alkyl (8-16) glucoside) coexists in an emulsion containing an alkyl acrylate emulsifier (Noveon, Inc., trade name: PEMULEN TR-2), an oil agent, and water. The composition corresponds to the example of Patent Document 2 (Japanese Unexamined Patent Publication No. 11-503461), but does not contain the compound (a) used in the present invention. Also, the detergency against the film-forming mascara containing a large amount of the alkyl acrylate copolymer was inferior to that of the examples.

(Comparative Example 11)
Each component was mixed with the composition shown in Table 6 to produce a cleansing composition, and the detergency against mascara was evaluated. Table 6 shows the evaluation results.

A composition in which isoparaffin is emulsified in water with a polyoxyethylene alkyl ether-based activator corresponds to the example of Patent Document 1 (JP-A-5-163116). However, even if oily mascara can be removed, an alkyl acrylate copolymer can be obtained. The detergency against the film-forming mascara containing a large amount of was inferior to that of the examples.
