Description
Technical Field
The present invention relates to a liquid composition for external application to skin, and more particularly to a liquid composition for external application to skin which provides a refreshing feeling, has an appropriate viscosity, is free from sagging, and has excellent stability.
Background
The liquid skin external composition such as antiperspirant has the following effects: since the coated skin is provided with a pleasant cool feeling, and sweat generation and body odor are suppressed, it is desired that the coating composition can be easily applied to the skin even during travel and has excellent quick-acting properties and coating properties.
However, if the liquid antiperspirant is taken from the container into the hand and applied to the skin in an expanded manner, the antiperspirant slips off the hand or flows on the skin in many cases, and the application is not easy.
In addition, after applying an antiperspirant, it is common to blend a powder into the antiperspirant to give a smooth feel to the skin surface, but if the powder blended into the antiperspirant is left to stand in advance, it will settle at the bottom of a container in which the antiperspirant is stored, and therefore, before use, it is necessary to vibrate the container sufficiently to disperse the powder throughout the antiperspirant and use it. Moreover, such a behavior of vibrating the container before use becomes a troublesome behavior for the user.
On the other hand, if a thickening agent of the type thickened by polymerization of the polymer chain is added to increase the viscosity of the antiperspirant, the effect of imparting a cool feeling which the antiperspirant should originally have is significantly impaired, although the antiperspirant can be inhibited from slipping off or settling of the powder, but the drying rate of the antiperspirant after application to the skin becomes slow or stickiness occurs even after drying.
Therefore, in the case of liquid skin external compositions such as antiperspirants, it is important to develop a liquid skin external composition which has an appropriate viscosity without impairing the effect of imparting a refreshing feeling, is free from sagging, suppresses the sedimentation of powder, and has excellent stability.

Detailed Description
The liquid composition for external application to the skin of the present invention comprises: (A) 20-60 mass% of monohydric alcohol; and (B) a microgel obtained by crushing a gel formed from a hydrophilic compound having gelling ability.
(A) Monohydric alcohol
Examples of the monohydric alcohol used in the present invention include methanol, ethanol, propanol, butanol, pentanol, hexanol, heptanol, octanol, and the like, and examples of monohydric alcohols having 1 to 8 carbon atoms, more preferably 1 to 3 carbon atoms include: a substance formed of a mixture of 1 or 2 or more selected from them.
(B) Microgel obtained by crushing gel formed from hydrophilic compound having gelling ability
In the present invention, the following microgels were used: a microgel having an average particle diameter of 0.1 to 1000 [ mu ] m, which is obtained by dissolving (heating and dissolving depending on the component) a hydrophilic compound having gelling ability in water or an aqueous component, then allowing the resulting solution to stand (or allowing the solution to stand and cool), and pulverizing the gel thus formed.
The microgel has an effect of improving viscosity by rubbing swollen microgel particles with each other, but can suppress a sticky feeling when applied to the skin compared with a thickener (thickening compound) of a type thickened by polymerization of a polymer chain, and therefore does not spoil a refreshing feeling.
The hydrophilic compound having a gelling ability is not particularly limited as long as it is a water-soluble compound having a gelling ability and can be used in the fields of cosmetics and pharmaceuticals. Specific examples thereof include hydrophilic gelling agents having gelling ability such as hydrophilic proteins having gelling ability such as gelatin and collagen, agar, curdlan, scleroglucan, gellan gum, alginic acid, carrageenan, mannan, pectin, and hyaluronic acid, and hydrophilic gelling agents such as crosslinked sodium N, N-dimethylacrylamide-2-acrylamide-2-methylpropanesulfonate copolymer and sodium acrylate/2-acrylamide-2-methylpropanesulfonic acid sodium salt copolymer. The hydrophilic compound having the gelling ability may be used in 1 kind or 2 or more kinds.
These hydrophilic compounds having gelling ability are dissolved (heated and dissolved depending on the components) in water or an aqueous component, and then allowed to stand (or stand and cooled) to solidify, thereby forming a gel. In the curing (gelation) after the dissolution by heating, it is particularly preferable that the heating is stopped and the mixture is allowed to stand (left) until the temperature becomes lower than the curing temperature (gelation temperature).
The aqueous component is not particularly limited as long as it is an aqueous component that can be used in the fields of cosmetics and pharmaceuticals, and may contain, for example, a component that is generally blended as an aqueous component of cosmetics, in addition to glycols such as 1, 3-butanediol and propylene glycol, and lower alcohols such as ethanol and propanol. Specific examples include chelating agents such as metaphosphate and ethylenediaminetetraacetate, pH adjusters, and preservatives, but are not limited to these.
The gel strength of the gel is not particularly limited as long as the gel itself can maintain its shape and the microgel of the next step can be obtainedAnd (4) determining. In the present invention, those having a relatively high gel strength can be used, and for example, those having a gel strength of 1000g/cm can be used2(measurement by cold water method) or less, and the gel strength is 30g/cm2A very weak gel strength around this can also give microgels. From the viewpoint of improvement in usability, the gel strength is preferably 100g/cm2The left and the right.
Further, for the purpose of changing the feeling of use, a thickening compound having no gelling ability may be used in combination with the hydrophilic compound having gelling ability. Examples of the thickening compound having no gelling ability include: hydrophilic synthetic polymers represented by polyacrylic acid, polyethylene glycol, polyacrylamide, polyalkylacrylamide/polyacrylamide copolymer, carboxymethyl cellulose, cationized cellulose, Pluronic (Pluronic); examples of the hydrophilic thickening compound include hydrophilic natural polymers typified by xanthan gum, succinoglycan, guar gum, and locust bean gum, and hydrophilic clay minerals such as saponite, bentonite, and montmorillonite. Also, salts of these compounds can be used. By using these hydrophilic thickening compounds having no gelling ability in combination, the gel strength of the obtained gel can be adjusted. The thickening compound having no gelling ability may be used in 1 kind or 2 or more kinds.
The gel formed from the hydrophilic compound having gelling ability is crushed by a homogenizer, a disperser, a mechanical stirrer, or the like to obtain a microgel having a predetermined average particle size. The microgel of the present invention has an average particle size of 0.1 to 1000. mu.m, preferably about 1 to 300. mu.m, and more preferably about 10 to 200. mu.m. When the average particle size of the microgel exceeds 1000. mu.m, the feeling is poor and the handling may be problematic, while when it is less than 0.1. mu.m, an appropriate viscosity may not be obtained. The average particle size of the microgel can be adjusted depending on the degree of pulverization, and when a smoother use is required, the microgel is crushed sufficiently by high-speed stirring to form a microgel having a fine particle size, while when the microgel itself is required to have a tactile sensation, the degree of crushing is reduced by gentle stirring to form a microgel having a slightly larger particle size.
The microgel used in the present invention can be obtained as follows: the gel is obtained by mixing (a) gellan gum and (b) a cation-forming gelation promoter as a hydrophilic compound having a gelation ability and pulverizing the formed gel.
As the gellan gum used in the present invention, there can be used: mixing D-glucose, D-glucuronic acid and L-rhamnose in a ratio of 2: 1: 1, 4 sugars bonded at a ratio of 1 as repeating units. Examples of commercially available gellan gum products include kelgel AFT (CP Kelco).
The gelation accelerator (b) which is blended with the gellan gum (a) and generates cations is not particularly limited as long as it has a function of gelling the gellan gum, and for example, it is possible to use: calcium salt, magnesium salt, sodium salt, potassium salt, dipotassium glycyrrhizinate, trimethylglycine, sodium metabisulfite, sodium citrate, potassium lactate, etc. which are dissolved in water to dissociate the salts, among which calcium chloride, magnesium chloride, sodium chloride, potassium chloride, etc. are preferably used.
(b) The amount of the cation-generating gelling agent to be blended is preferably 0.001 to 10% by mass of the total cosmetic composition, and is preferably 0.15 to 50 times the amount of gellan gum by mass. When the amount of the compound is less than 0.001% by mass based on the whole cosmetic, it is substantially difficult to sufficiently gel the whole cosmetic, and when the amount of the compound is more than 10% by mass based on the whole cosmetic, the feeling of use is rather deteriorated when the compound is applied to the skin.
In the step for obtaining a microgel, it is preferable to add (a) a gellan gum and (b) a cation-generating gelation promoter to water or an aqueous component, heat-dissolve them, then allow them to stand and cool, pulverize the obtained gel to form a microgel, and disperse the microgel in a monohydric alcohol to obtain a liquid composition for external application to skin. This is because, after (a) the gellan gum and (b) the cation-forming gelling agent are heated and dissolved, the resulting gel is pulverized while stirring and cooled to obtain a microgel, and even if the obtained microgel is dispersed in a monohydric alcohol, a predetermined viscosity cannot be obtained, and it is difficult to suppress sagging of an antiperspirant or the like, which is an object of the present invention.
In addition, the microgel used in the present invention can also be obtained as follows: the gel may be obtained by mixing water or an aqueous component with agar (c) and pulverizing the obtained gel.
When the agar (c) is used as the hydrophilic compound having the gelling ability, it is preferable that the agar (c) is added to water, dissolved at room temperature, allowed to stand and cool, and the gel is pulverized into a microgel and dispersed in a monohydric alcohol to obtain a liquid composition for external application to skin. This is because if the stirring is continued during the formation of the gel in which the component (c) is dissolved, a predetermined viscosity cannot be obtained even if the gel is then pulverized and dispersed in a monohydric alcohol, and there is a risk that it becomes difficult to suppress sagging of the antiperspirant and the like, which is an object of the present invention.
The liquid composition for external application to skin of the present invention may further contain a powder as component (C). In the liquid skin external composition containing a predetermined amount of a monohydric alcohol and a microgel obtained by pulverizing a gel comprising a hydrophilic compound having gelling ability, a moderate viscosity can be imparted without impairing the refreshing feeling required for antiperspirants and the like, and therefore, the powder can be stably maintained in a dispersed state for a long period of time.
As the powder of the component (C), for example, inorganic powders (for example, talc, kaolin, mica, sericite (serite), muscovite, phlogopite, synthetic mica, lepidolite, biotite, vermiculite, magnesium carbonate, calcium carbonate, aluminum silicate, barium silicate, calcium silicate, magnesium silicate, strontium silicate, metal tungstate, magnesium, silica, barium sulfate, calcined calcium sulfate (calcined gypsum), calcium phosphate, fluorapatite, hydroxyapatite, ceramic powder, metal soap (for example, zinc myristate, calcium palmitate, aluminum stearate), boron nitride, etc.) are preferable; organic powders (for example, polyamide resin powder (nylon powder), polyethylene powder, polymethyl methacrylate powder, benzoguanamine resin powder, polytetrafluoroethylene powder, cellulose powder, and the like) and the like, which impart smooth handling properties after coating.
The liquid composition for external application to the skin of the present invention may contain, as components for imparting an antiperspirant/deodorant function, aluminum compounds such as alum (aluminum potassium sulfate), aluminum chlorohydrate and aluminum chloride, zinc compounds such as zinc phenolsulfonate and zinc oxide, and antibacterial components such as benzalkonium chloride, benzethonium chloride, isopropylmethylphenol and antibacterial zeolite. As with zinc oxide, components that are not soluble in water or alcohol can be directly dispersed in a powder state and compounded.
In addition, the liquid composition for external application to skin of the present invention may contain components that can be blended in a general composition for external application to skin, within a range that does not impair the effects of the present invention. Examples of such components include surfactants, drugs, buffers, perfumes, bactericides, humectants, thickeners, pH adjusters, preservatives, antioxidants, chelating agents, whitening agents, ultraviolet absorbers, coloring materials, and the like. These components may be added to water for dissolving the hydrophilic compound having gelling ability or a monohydric alcohol for dispersing the microgel.
The liquid composition for external application to skin of the present invention gives a refreshing feeling and has an appropriate viscosity, and therefore, does not sag even when held in the hand and has a characteristic of being easily applied to the skin, and therefore, can be used as an antiperspirant or deodorant product. In addition, if the cosmetic is stored in a container provided with a one-touch cap (dispenser), the cosmetic can be used as a portable cosmetic.
The viscosity of the liquid composition for external application to skin of the present invention at 30 ℃ is preferably 1000 mPas or more. By maintaining such a viscosity, the composition can be held without sagging even by hand, has a property of being easily applied to the skin, and can suppress sedimentation of the powder when the powder is blended.
The viscosity of the liquid skin external composition is not particularly limited, and the form of the container to be stored may be selected according to the viscosity. For example, if the viscosity of the liquid composition for external application to the skin is 6000mPa · s or less, the amount of the liquid composition for external application to the skin can be reduced by storing the liquid composition in a bottle container, and the liquid composition can be used up to the end and can provide a good feeling of ease of use. On the other hand, if it is 6000 mPas or more, the container is stored in a tube container, so that the amount of the container can be reduced, the container can be used up to the end, and the portability can be improved.

< evaluation Standard >
A: excellent (acceptable), B: slightly poor (fail), C: poor (unqualified)
Table 1 shows the difference in viscosity of the liquid external skin composition due to the difference in the manufacturing process for obtaining the microgel.
Example 1 the following procedure was used: a liquid composition for external application to skin was obtained by adding ingredients such as gellan gum, sodium chloride and calcium chloride to water, dissolving the resultant mixture by heating, allowing the mixture to stand and cool, and then pulverizing the formed gel to form a microgel and dispersing the microgel in monohydric alcohol (ethanol), and comparative example 2 used the following procedure: the same components as in example 1 were added to water, and after heating and dissolving, the gel obtained was cooled while stirring, and the gel obtained was pulverized to disperse the microgel in monohydric alcohol (ethanol) to obtain a liquid composition for external application to skin.
As shown in table 1, it was confirmed that example 1 had an appropriate viscosity and was effective in preventing the powder from settling and slipping off the hand. On the other hand, comparative example 2 is the following result: a sufficient viscosity could not be obtained, and the powder settled and slipped from the hands.
[ Table 1]
Next, liquid skin external compositions (examples 2 and 3) thickened by dispersing a microgel obtained by pulverizing a gel formed from a hydrophilic compound in a monohydric alcohol and liquid skin external compositions (comparative examples 2 to 7) thickened by dissolving a conventional thickener in water were evaluated in comparison.
The formulations of examples 2 and 3 and comparative examples 2 to 7 are shown in table 2, and the following steps are employed for examples 2 and 3 in the same manner as in example 1: the liquid composition for external application to the skin is obtained by dissolving a hydrophilic compound for forming a gel in water, allowing the resulting solution to stand for cooling, and then pulverizing the formed gel to form a microgel and dispersing the microgel in an alcohol.
[ Table 2]
As shown in table 2, in examples 2 and 3, the powder did not settle and slip off the hand, and the dispersion of the precipitated components when the powder was dried on the skin did not occur even when the powder was applied to the skin, and it was confirmed that the results were good. In the case of the structure in which the microgel is filled in the preparation as in examples 2 and 3, the sedimentation of the powder with time can be prevented and the dispersion at the time of drying is not caused, but in the case of using the conventional thickener in which the viscosity is increased by the polymerization of the polymer as in comparative examples 2 to 7, the following results are obtained: even if the amount of the additive is increased, the powder cannot be prevented from settling, and even if the amount is small, deviation occurs during drying.
Table 3 shows the results of the investigation of the compounding amount of the monohydric alcohol. Examples 2 and 4 to 7 are as follows: the gellan gum and the gelation accelerator (sodium chloride, calcium chloride) are dissolved in the total amount of water in the formulation, and the formed gel is pulverized to obtain a microgel.
[ Table 3]
When the amount of water is large and the amount of monohydric alcohol (ethanol) is small, the viscosity tends to increase because the proportion of water to the monohydric alcohol or to the gel increases, but when the amount of monohydric alcohol is less than 20% as in comparative example 8, drying becomes slow or stickiness occurs when the gel is applied to the skin, and problems such as separation of oil-soluble components such as perfume during production occur. On the other hand, as in comparative example 9, if the monohydric alcohol is more than 60%, the amount of water constituting the gel decreases, and therefore, an appropriate viscosity cannot be obtained, and as a result, the powder falls, slips from the hands, and the like, resulting in "poor (defective)".
The following is an example of a formulation using the liquid composition for external application to the skin of the present invention. It was confirmed that in any formulation example, an excellent refreshing feeling was obtained, and the powder was stably maintained in a dispersed state for a long period of time without sagging even when held in the hand with an appropriate viscosity. The present invention is not limited to the above examples.
