[0001] LIQUID SKIN CLEANSER COMPOSITION [0002]

The present invention relates to a liquid skin cleanser composition which is excellent in the creaminess of the foam diary, has no skin irritation, gives a moist feeling after towel drying, and has good low-temperature stability.

The liquid skin detergent composition is required to be excellent in the amount of foam and quality during cleaning, and is free from slippage after rinsing and can be cleanly washed. Among them, a liquid skin cleanser composition in which a fatty acid salt (RCOOM (M is Na and K) as a main base agent is superior to a general surfactant in creaminess of foamy diary, , And it has been used for a cleanser, a body soap, a hand soap, etc. because of a fresh rinse feeling.

However, the liquid skin cleansing composition containing the above-mentioned fatty acid salt has a problem in that the pH is lowered due to the absorption of carbon dioxide in the air and the hydrolysis of the flavor (especially ester system) in the past and the fatty acid salt becomes a water- A relatively hydrophobic polyhydric alcohol such as propylene glycol, dipropylene glycol, polyethylene glycol, or 1,3-butylene glycol has been used as a solvent (see Patent Document 1) ).

In addition, since the consciousness change of the modern woman's skin and the awareness of care for the child are increased, the skin quality of her own skin is considered as sensitive skin, and the milder detergent is used for the child There is a need for a liquid skin cleanser composition that gives a feeling of moistness even after drying, especially in winter. However, the relatively small number of polyhydric alcohols such as propylene glycol makes the intercellular lipid structure in the keratinous substance to be loose, and the permeability to the skin is high. Therefore, the liquid skin detergent composition containing the above components has a weak skin barrier function It was a problem to have irritation to the skin of sensitive skin. In addition, the relatively small number of polyhydric alcohols such as propylene glycol has a low ability to retain moisture, so that it is difficult to obtain a sufficiently moist feeling by drying or pulling after cleaning.

For example, Patent Document 2 includes (a) a fatty acid salt represented by the following general formula (1)

R ¹ COOM ... In general formula (1)

(In the general formula (1), R ¹ represents a linear or branched monovalent hydrocarbon group having 5 to 25 carbon atoms, and a part of the hydrogen atoms may be substituted with a hydroxyl group.) M represents an alkali metal.

(b) an amphoteric surfactant or a semipolar surfactant,

(c) a compound having an acid dissociation constant of from 8.0 to 11.0, wherein in the component (a), a fatty acid salt in which R ^{1 in} the general formula (1) is not more than 11, 1) has a mass ratio of 1.5 to 10.0, wherein R ¹ is a fatty acid salt having 12 or more monovalent hydrocarbon groups. According to this proposal, a liquid detergent composition excellent in low-temperature stability and foam dischargeability and excellent in inspection performance can be obtained.

However, in this proposal, since propylene glycol is used as the polyhydric alcohol, there is a problem that the user of the sensitive skin has a skin irritating property, and after the cleaning, it is dried or pulled, and a sufficiently moist texture can not be obtained .

On the other hand, glycerin is known as a polyhydric alcohol having high hydrophilicity and high water retaining ability. When propylene glycol is replaced with glycerin, there is a problem that precipitation of fatty acid occurs when stored at a low temperature.

In addition, in the liquid skin cleanser composition, it is preferable that the fragrance when washing is remained even after rinsing is reminiscent of a washing power or for pleasant hand-washing. However, in the system using propylene glycol and glycerin in combination, since propylene glycol is a hydrophobic solvent, even when a perfume ingredient is added, it dissolves in the bulk and flows during rinsing, making it difficult to leave a fragrance on the skin.

Japanese Patent Application Laid-Open No. 2002-80345 International Publication No. 2007/145054 pamphlet

It is an object of the present invention to solve the above-mentioned conventional problems and to achieve the following objects. That is, the present invention has a good foaming diary at the time of use. It is excellent in the creaminess of the bubble diary, has no irritation to the skin, can be used safely to the child who has sensitive skin and weak skin, gives a moist feeling after the towel dry, and also causes the precipitation of fatty acid even when stored at low temperature It is an object of the present invention to provide a liquid skin cleanser composition which is free from scum and which has good low-temperature stability.

(A) a fatty acid potassium salt (soap) represented by the general formula (1): R ¹ COOK (wherein, in the general formula (1), R ¹ Represents a linear or branched monovalent hydrocarbon group having 5 to 25 carbon atoms and a part of the hydrogen atoms of the monovalent hydrocarbon group may be substituted with a hydroxyl group) The pH is lowered by decomposition, and fatty acids are precipitated. Propylene glycol, dipropylene glycol, polyethylene glycol, and 1,3-butylene glycol, which have high hydrophobicity, have a high ability to dissolve fatty acids, but are irritating to users of sensitive skin having weak skin and are not preferable for use . Glycerin, even with the same polyhydric alcohol, has low skin irritation and has a moisturizing power, so that a hand soap of good texture can be made, but the solubility of the fatty acid is low and the low temperature stability is poor because it is hydrophilic. This low-temperature stability is considered to be because the pH is lowered at the time of setting (at the time of setting), and the dissociation equilibrium of the fatty acid potassium salt and the fatty acid is shifted to the fatty acid side having poor solubility.

Therefore, the inventors of the present invention have extensively searched for a substance having a buffering ability at around pH = 10. As a result, it has been found that (B) amines represented by the general formula (2): R ² -NH ₂ , R ² represents a linear or branched monovalent hydrocarbon group having 1 to 6 carbon atoms and part of the hydrogen atoms of the monovalent hydrocarbon group may be substituted with a hydroxyl group (hydroxyl group) And that the storage stability at low temperature is improved by using glycerin without using polyhydric alcohol having high hydrophobicity such as propylene glycol. As a result, skin irritation of the liquid skin cleanser composition can be minimized.

Further, (A) the general formula (1): that a review about the ratio of fatty acid potassium salt of a fatty acid chain length represented by R ¹ COOK, of the R ¹ carbon number of fatty acid potassium salt less than 11 (C ₁₁ or less), and R ¹ (C ₁₁ or higher / C ₁₂ or higher) of the fatty acid potassium salt having a carbon number of 12 or higher (C ₁₂ or higher) in the range of 1.5 to 5 is preferable, and the fatty acid potassium salt as the component (A) (A / C) with glycerin in the range of 0.3 to 3.0 exhibit excellent creaming characteristics in the foamy weather, moist feeling after drying, and storage stability at a low temperature.

Further, when 5% by mass or more of glycerin as the component (C) was added, the moist feeling after drying was improved. Further, by replacing propylene glycol with glycerin, the creaminess of the foamy diary was improved. This is because the hydrophobicity of the solvent is weakened by replacing polyhydric alcohols having high hydrophobicity such as propylene glycol with hydrophilic glycerin. As a result, it is considered that the foam membrane is rigid by promoting the adsorption of the surface of the soap powder, and the creaming property of the foam diary is improved.

More preferably, by blending 1% by mass to 20% by mass of a hydrophilic sugar alcohol as the component (D), it is possible to solve the clogging of the pump, to moisturize the skin, Respectively.

More preferably, 0.05% by mass to 3% by mass of any one of the ampholytic surfactant and the semi-polar surfactant as the component (E) is mixed to improve the quality of the gel, to make the creamy foam more abundant, To give a smooth texture.

More preferably, it has been found that by blending a certain amount of the specific flavor as the component (F) with respect to the glycerin as the component (C), the specific flavor tends to remain on the skin even after rinsing.

By filling the foam container with the liquid skin detergent composition having the above characteristics, it is possible to dispense a foam, to discharge a creamy foam from the beginning, and to prevent the liquid skin, which gives a moist and good texture, It is possible to provide a liquid skin cleanser composition which can realize a detergent composition and which can be safely used even for a child with sensitive skin or a child with sensitive skin without causing clogging which is a drawback of a former container. Thereby completing the invention.

<(A) Fatty acid potassium salt represented by the general formula (1): R ¹ COOK>

As the fatty acid potassium salt as the component (A), a compound represented by the following general formula (1) is used.

R ¹ COOK ... In general formula (1)

In the general formula (1), R ¹ represents a linear or branched monovalent hydrocarbon group having 5 to 25 carbon atoms, and a part of the hydrogen atoms of the monovalent hydrocarbon group may be substituted with a hydroxyl group.

R ¹ preferably has 5 to 25 carbon atoms, preferably 7 to 17 carbon atoms, and more preferably 11 to 17 carbon atoms in terms of "straight-chain or branching" from the viewpoint of "creaming property of foamy diary" Chain monovalent hydrocarbon group, and may be saturated or unsaturated.

If the number of carbon atoms is less than 5, it may fall out in terms of skin irritation, crease of foamy diary, and foamy diary. If it exceeds 25, low-temperature stability may be poor.

As the fatty acid potassium salt as the component (A), a fatty acid potassium salt in which R ¹ in the general formula (1) is a monovalent hydrocarbon group having a carbon number of 11 or less and a fatty acid potassium salt in which R ¹ in the general formula (1) A fatty acid potassium salt, which is a monovalent hydrocarbon group, is suitably used. These may be used alone, or two or more kinds may be used in combination.

Examples of the fatty acid potassium salt in which R ¹ in the general formula (1) is a monovalent hydrocarbon group having not more than 11 carbon atoms include potassium caprate, potassium heptanoate, potassium caprylate, potassium pelaric acid, potassium caprylate, Potassium permanganate, potassium laurate, potassium caprylate, potassium undecylenate, potassium lauroolate, potassium 2-ethylbutanoate, potassium isopentanoate, potassium 2-ethylpentanoate, potassium 2-ethylhexanoate , Potassium isononanoate, potassium 3,5,5-trimethylhexanoate, and the like.

Examples of the fatty acid potassium salt in which R ¹ in the general formula (1) is a monovalent hydrocarbon group having 12 to 25 carbon atoms include potassium tridecanoate, potassium tetramethylononanoate, potassium myristate, potassium pentadecanoate, Potassium stearate, potassium stearate, potassium arachic acid, potassium behenate, potassium lignosulphate, potassium lecithin, potassium myristoleate, potassium palmitoleate, potassium oleate, potassium laurate, potassium kononate, Potassium laurate, potassium linolenate, potassium arachidonate, potassium 2-hexyldecanoate, potassium isostearate, potassium 12-hydroxystearate, and the like.

Further, potassium salts such as palm oil fatty acid, cured palm oil fatty acid, palm oil fatty acid, hard palm oil fatty acid, palm kernel oil fatty acid, hardened palm kernel oil fatty acid, tallow fatty acid and hardened tallow fatty acid, which are a mixture of fatty acids,

Among these, from the point of view of the creaminess of the bubble diary and the "low-temperature stability", the blending temperature at the time of production and the odor of the fatty acid remain in use, potassium laurate, potassium myristate, potassium palmitate, potassium stearate, potassium isostearate, Potassium and palm oil fatty acid potassium are preferable, and potassium laurate, potassium myristate, potassium palmitate, and palm oil fatty acid potassium are particularly preferable.

These fatty acid potassium salts may be blended with potassium fatty acid as a raw material, but fatty acid and potassium hydroxide may be added to the mixing tank to form potassium fatty acid.

Examples of the salt to be a counterpart of the fatty acid include an alkali metal such as sodium and lithium, and a potassium salt of fatty acid is particularly preferable from the viewpoint of suppressing precipitation and is used in the present invention. Amino acids are also widely used as salts for the fatty acids, but they are not used in the present invention because they may cause deterioration of color tone and aroma when stored at high temperatures.

The component (A) wherein the carbon number of R ¹ fatty acid potassium salt of the following ₁₁ (C 11 or less) and the number of carbon atoms is the salt of 12 or more fatty acid potassium of R ¹ mass ratio of the (C ₁₂ or greater) (C ₁₁ or less / C ₁₂ or more) Is preferably from 1.5 to 5, and more preferably from 1.7 to 4, from the viewpoints of low-temperature stability, creaminess of foamy diary, and skin irritation. This, of R ¹ is the number of carbon atoms is at least 12: 1 hydrocarbon group fatty acid potassium salt is likely to be the main cause of the precipitation, in particular, because it significantly at the time when the pH is lowered and the low temperature, the weight ratio (C ₁₁ or less / C ₁₂ Or more) is less than 1.5, the low-temperature stability may be remarkably lowered, and if it is more than 5, the creaminess of the foaming period may be lowered and skin irritation may occur.

The content of the fatty acid potassium salt represented by the general formula (1) in the component (A) is 4% by mass to 20% by mass with respect to the total amount of the liquid skin cleanser composition, and from the viewpoint of low temperature stability and creaminess of the foam diary, By mass to 16% by mass. If the content of the component (A) is less than 4% by mass, the foamability of the foaming agent may be insufficient. If the content of the component (A) exceeds 20% by mass, precipitation may occur at a low temperature and the low-temperature stability may deteriorate.

&Lt; (B) Amines represented by general formula (2): R ² -NH ₂ >

As the amine (B), a compound represented by the following general formula (2) is used.

R ² -NH ₂ ... In general formula (2)

In the general formula (2), R ² represents a linear or branched monovalent hydrocarbon group of 1 to 6 carbon atoms, preferably 1 to 4 carbon atoms, and a part of the hydrogen atoms of the monovalent hydrocarbon group is a hydroxyl group . When the number of carbon atoms is more than 6, solubility in the system (system) is poor, and it may become difficult to ensure low-temperature stability.

The monovalent hydrocarbon group may be either saturated or unsaturated, and examples thereof include a methyl group, an ethyl group, and a propyl group.

The amine represented by the general formula (2) is not particularly limited as long as it has an acid dissociation index of 9.0 or more, and can be appropriately selected in accordance with the purpose. Examples thereof include monoethanolamine (9.64), ethylamine (10.66) , 2-amino-2-methyl-1-propanol (9.82), isopropanolamine (9.68) and isopropylamine (10.93). These may be used alone, or two or more kinds may be used in combination. Among them, monoethanolamine (9.64), ethylamine (10.66) and isopropanolamine (9.68) are particularly preferable in view of low-temperature stability and no coloring during long-term storage.

The acid dissociation index is -log [acid dissociation constant], and the acid dissociation constant is a value measured at 25 占 폚.

The content of the amine (B) is preferably from 0.2% by mass to 2% by mass, more preferably from 0.3% by mass to 1% by mass from the viewpoint of low temperature stability and skin irritation with respect to the total amount of the liquid skin cleanser composition Do. If the content of the component (B) is less than 0.2 mass%, improvement in low-temperature stability may be insufficient, and if it exceeds 2 mass%, skin irritation may occur.

&Lt; (C) Glycerin >

As the glycerin as the component (C), there is no particular limitation, and any of glycerides of a fatty acid hydrolyzed or chemically synthesized may be used. However, glycerin obtained by hydrolyzing a fatty acid triglyceride derived from a vegetable oil fit. Among these, crude glycerin obtained by hydrolyzing palm oil, palm kernel oil, palm oil, rapeseed oil and sunflower oil is purified from the viewpoint of "creaming property of bubble diary", "skin irritation property" and "moist feeling after drying" Particularly preferred.

The method for purifying glycerin as the component (C) is not particularly limited and can be appropriately selected in accordance with the purpose. However, it is preferred that the distillation is highly distilled and then the ion exchange resin treatment or the activated carbon treatment is carried out to remove the impurities, Do.

The content of glycerin as the component (C) is preferably from 5% by mass to 30% by mass with respect to the total amount of the liquid skin cleanser composition, and is preferably from 7% by mass to 20% by mass from the viewpoint of low temperature stability and creaming property . If the content of the component (C) is less than 5% by mass, low-temperature stability and moist feeling after drying may be inferior. When the content is more than 30% by mass, the creaminess of the foamy diary may be deteriorated.

In the present invention, the mass ratio (A / C) of the potassium salt of the fatty acid as the component (A) to the glycerin as the component (C) is 0.3 to 3.0, and in terms of the creaminess of the foamy diary and the moist feeling after drying 0.6 to 2.0 is preferable. If the mass ratio (A / C) is less than 0.3, the low-temperature stability is deteriorated. If the mass ratio (A / C) is more than 3.0, the creaming property of the foaming period may be deteriorated.

In the present invention, it is preferable not to include a polyhydric alcohol other than glycerin (excluding sugar alcohol) as the component (C).

(IOB value = 3.33) and dipropylene glycol (IOB value = 1.83), which tend to dissolve fatty acids having a low solubility, in the low-temperature stability of the fatty acid potassium salt as the component (A) The use of polyhydric alcohols other than sugar alcohols of less than 4 is well known in the art.

(IOB value = 5.00) which is a component (C) having an IOB value of 4 or more, which inhibits the low-temperature stability of the fatty acid potassium salt as the component (A) It is on.

Herein, the IOB value (abbreviated as Inorganic Organic Balance) refers to an oil component (meaning an oil component of a mineral oil, and refers to oil fractions such as oils, waxes, hydrogen carbides, higher fatty acids, higher alcohols, esters, (The same applies to common alcohols and fatty acids, etc.), the same applies hereinafter), and is a value indicating the ratio of the inorganicity to the organic matter (Organic value) "is 20 and the" inorganic value "is 100 for one copper hydroxide group, and the value is calculated based on the inorganic value of another substituent (inorganic group) based on this value Specifically, the IOB value = the inorganic value of the oil / the organic value of the oil (see, for example, Fujita et al., "Organic Analysis" (1930) published by Kaniya Bookstore).

Use of polyhydric alcohols other than the alcohol having an I.O.B value of less than 4 may maintain low-temperature stability, but may result in poor creaming properties of the foamy diary, susceptibility to skin irritation, and poor moist feeling after drying. On the other hand, in the case of using glycerin as the component (C), the creaminess of the foam diary can be realized while ensuring low-temperature stability, and skin irritation is not observed. This is a new knowledge of the present inventors.

For this reason, polyhydric alcohols other than sugar alcohol having the above-mentioned I O.B value of less than 4 are highly hydrophobic and increase the solubility of soap molecules, so that the interfacial adsorption of soap molecules is lower than that of pure water. On the other hand, glycerin as the component (C) is extremely hydrophilic and is considered to enhance the interface adsorption of soap molecules. In addition, it is known that skin irritation penetrates intercellular lipids showing the barrier function of skin into a surfactant such as soap and affects the dermis from the stratum corneum. It is also known that polyhydric alcohols other than polyhydric alcohols having an I.O.B value of less than 4 are highly compatible with intercellular lipids and make the intercellular lipid structure loose, thereby promoting the penetration of the surfactant. Therefore, polyhydric alcohols other than sugar alcohols having an IOB value of less than 4 promote the penetration of the surfactant, whereas glycerin as the component (C) does not impair the intercellular lipid function and prevents penetration of soap It is considered that the skin irritation is low.

In addition, glycerin as the component (C) has low solubility in the potassium salt of the fatty acid as the component (A), and thus has a low temperature stability until now. However, by combining with the amine (B), it is possible to ensure the low temperature stability of the potassium salt of the fatty acid (A) even when glycerin, which is the component (C), is used, Which is one of the achievements of the present invention.

<(D) Sugar Alcohol>

In the liquid skin detergent composition of the present invention, it is preferable that the sugar alcohol is blended as the component (D) in view of preventing the clogging of the pump and providing a feeling of bruising after drying.

The sugar alcohol as the component (D) is not particularly limited and can be appropriately selected in accordance with the purpose. Examples thereof include erythritol, arabitol, xylitol, galactitol, sorbitol and mannitol. These may be used alone, or two or more kinds may be used in combination. Of these, sorbitol, xylitol, mannitol and galactitol are more preferable, and sorbitol is particularly preferable in view of preventing the clogging of the pump and providing a feeling of being prickly after drying.

The content of the sugar alcohol as the component (D) is preferably 1% by mass to 20% by mass, and more preferably 3% by mass to 10% by mass, based on the whole amount of the liquid skin cleanser composition. If the content is less than 1% by mass, the effect of suppressing the clogging of the pump is small, and the feeling of being sticky after drying may be poor. When the content exceeds 20% by mass, the effect of suppressing the clogging of the pump is small, Since the ness is reduced and it becomes sticky after drying, there is a feeling that the feeling which is not conspicuous may fall behind.

In the present invention, the mass ratio (C / D) of the glycerin as the component (C) to the sugar alcohol as the component (D) is preferably 0.5 to 14, Lt; RTI ID = 0.0 &gt; 1 &lt; / RTI &gt; If the mass ratio (C / D) is less than 0.5, the effect of suppressing the clogging of the pump is small and the feeling of being bogged after drying may be poor. When the mass ratio is more than 14, the effect of suppressing the clogging of the pump is small. Because it is sticky, there is a feeling that it feels bad.

&Lt; (E) Amphoteric surfactant or semi-polar surfactant >

In the liquid skin detergent composition of the present invention, it is preferable to blend an amphoteric surfactant or a semi-polar surfactant as the component (E), in view of the amount of bubble diarrhea and the feeling of being softer at the time of rinsing, Do.

Examples of the amphoteric surfactant include imidazoline type (amide amine type), carbobetaine type, sulfobetaine type, phosphobetaine type and the like. These may be used alone, or two or more kinds may be used in combination.

Examples of the imidazoline type include palm oil alkyl-N-hydroxyethyl imidazolinium betaine and the like.

Examples of the carbobetaine include alkylbetaines such as laurylbetaine and lauryldimethylaminoacetic acid betaine; Lauric acid amide propyl betaine, palm oil fatty acid amide propyl betaine and the like.

Examples of the sulfobetaine include alkylsulfobetaines such as coconut oil fatty acid dimethylsulfopropyl betaine; And alkyl hydroxysulfobetaines such as lauryl dimethyl amino hydroxysulfobetaine.

Examples of the phosphobetaine include laurylhydroxyphosphobetaine and the like.

The amphoteric surfactant may contain sodium chloride in the production process, and it is more preferable to perform the desalting treatment from the viewpoint of improving the low-temperature stability.

The semi-polar surfactant means an alkylamine oxide type nonionic surfactant.

Examples of the above-mentioned semi-polar surfactant include acyl tertiary amine oxide, acyl tertiary phosphonoxide and the like. These may be used alone, or two or more kinds may be used in combination.

Examples of the acyl tertiary amine oxides include lauryldimethylamine oxide, POE palm oil alkyldimethylamine oxide, dihydroxyethyl lauryl amine oxide, and the like.

Examples of the acylic tertiary phosphonoxide include lauryldimethylphosphonous acid and the like.

Among them, the amount of the bubble diarrhea and the amount of the surfactant lauryldimethylaminoacetic acid betaine, lauric acid amide propylbetaine, coconut fatty acid amide propylbetaine , And lauryldimethylamine oxide, a semi-polar surfactant, are particularly preferred.

The content of the amphoteric surfactant or semi-polar surfactant as the component (E) is preferably 0.05% by mass to 3% by mass with respect to the total amount of the liquid skin cleanser composition, and the amount of the foam diary, the creaminess of the foam diary, More preferably 0.5% by mass to 1% by mass from the viewpoint of suppressing a stiff feeling at the time of rinsing and giving a smooth feeling to the skin. If the content of the component (E) is less than 0.05% by mass, a sufficient effect may not be obtained from the viewpoint of the amount of foaming diarrhea and smoothness at the time of rinsing. When the content is more than 3% by mass, And the smoothness at the time of rinsing may be poor.

&Lt; Specific fragrance which is component (F) >

The specific fragrance as the component (F) is contained for the purpose of enhancing the reverberation of the fragrance to the skin. In order to leave a fragrance, especially a citrus flavor, on the skin, the compound having a clogP value of 5.1 to 6.3 .

The clogP value is a value obtained by dividing the 1-octanol / water partition coefficient (P), which represents the ratio of the equilibrium concentration of 1-octanol and water (in water) And the lower the hydrophilicity, the higher the hydrophilicity. The clogP value is obtained by decomposing the chemical structure of a compound into its constituent elements by the f value method (hydrophobic fragment integer method), integrating the hydrophobic fragment constant f of each fragment (See, for example, Clog 3 Reference Manual Daylight Software 4.34, Albert Leo, David Weininger, Version 1, March 1994). The clogP value was obtained from a database provided by Syracase research corpration.

If the clogP value is less than 5.1, hydrophilicity increases and the effect on remaining skin may be thinned. If the clogP value is more than 6.3, the hydrophobicity tends to be high and the skin tends to be improved. On the contrary, the clogP value tends to dissolve in a water- It may be difficult and the stability may be deteriorated.

Examples of the fragrance having a clogP value of 5.1 to 6.3 as the component (F) include, for example, galactoside (clogP = 6.3), hexyl salicylate (clogP = 5.1), moscone (clogP = 6.0) It is preferable in terms of skin remaining. These may be used alone, or two or more kinds may be used in combination. Among them, galactoside (clogP = 6.3) is particularly preferable.

The content of the fragrance having a clogP value of 5.1 to 6.3 of the component (F) is preferably 0.005 mass% to 1 mass% with respect to the total amount of the liquid skin detergent composition, more preferably 0.01 mass% More preferably 0.5% by mass. When the content is more than 1% by mass, precipitation at a low temperature or a decrease in the foaming period is observed, which is not preferable.

The mass ratio (F / C) of glycerin as the component (C) to the fragrance having a clogP value of 5.1 to 6.3 of the component (F) is preferably 0.001 to 0.1, more preferably 0.001 to 0.05. When the mass ratio (F / C) is less than 0.001, there is almost no residual skin with an effective smell, and when the mass ratio (F / C) is more than 0.1, the skin remaining effect of aroma is not remarkably improved.

- Other ingredients -
