Description

  The present invention relates to a cosmetic composition containing water, a polysaccharide, and a polyhydric alcohol, having a stable viscosity and hardness over a long period of time without impairing the feeling of use, and a method for producing the same.

  Since cosmetics are required to have a multi-functional effect depending on the type of cosmetics, they contain a great variety of ingredients. For example, a functional oily base having functions such as cleansing, water retention, scrubbing effect, emollient effect, protective effect, etc., and cosmetic spreadability, lubricity, glossiness, adhesion, etc. on the skin surface As an agent or functional granule, components such as an organic solvent, an organic pigment, an inorganic pigment, an oil agent, a moisturizer, an astringent, a whitening agent, an ultraviolet ray inhibitor, an antioxidant, and a fragrance are included. When this functional oil base or functional granule is used in cosmetics, various types of surfactants are selected and used according to the required HLB of the functional oil base and the surface properties of the functional granule. , Emulsification and dispersion were performed (see Non-Patent Documents 1 to 4). In addition, since cosmetics are required to have multiple functions, various functional oil bases and functional granules can be stably maintained in a single cosmetic, and a stable emulsified dispersion state for a long time over a wide temperature range. There is a need to maintain. For example, since cosmetics generally have a long product display period after use and a long period of use after user purchase, the initial kinematic viscosity and hardness of the cosmetics increase by standing for a long period of time, resulting in a significant change in product properties. As a result, there is a problem that the feeling of use of the cosmetic material is remarkably impaired. This tendency was particularly prominent when stored for a long time at a high temperature. In addition, cosmetics are easy to take from a container to a hand or a finger, and a touch with little stickiness is emphasized.

  In general, a polysaccharide, which is a hydrophilic polymer substance, is blended in cosmetics in order to maintain an emulsified and dispersed state. Also, water-soluble polyhydric alcohols such as glycerin are blended for various purposes such as imparting water retention and moist feeling to cosmetics, improving the familiarity of functional oil bases or functional granules. However, when the amount of the polysaccharide is increased, the cosmetic material may have a “stickiness”, or the elongation and smoothness of the cosmetic material may be lost. In addition, the presence of polyhydric alcohols in polysaccharides increases the viscosity and hardness of cosmetics, which not only affects the stability of cosmetics over time, but also the feeling of use of cosmetics. Will be severely damaged.

  Therefore, a number of improvement measures have been proposed to solve such problems. For example, a method of improving the stickiness of cosmetics containing water-soluble polyhydric alcohol by blending specific polysaccharides (Patent Document 1), reducing the amount of surfactant by blending polysaccharides and applying the whitening component to the skin A specific polysaccharide is added to powdery aqueous cosmetics such as a method for improving the stabilization of the formulation (Patent Document 2), foundation, carmine lotion, lotion, emulsion, etc. And improving the stability of the dispersed state (Patent Document 3), adding a specific polysaccharide to a skin external preparation containing a medicinal or functional ingredient, improving viscosity stability over time and skin feel Skin external preparation (Patent Document 4) that improves the skin, conditioner that improves the yield of active ingredients on the hair, imparts “smoothness” and “moistness” to the hair, and improves the hair damage suppression effect, etc. Head of Cosmetics (Patent Document 5), a method for preparing a topical skin preparation for improving long-term stability of unstable components and altered components (Patent Document 6) by blending a specific polysaccharide, a plurality of polysaccharides and high hydrophilicity There is a method for preparing cosmetics (e.g., Patent Document 7) in which emulsion dispersibility is improved at low cost without impairing the feeling of use using a molecular substance. Furthermore, the present inventors have invented cosmetics having high emulsification dispersion stability by a three-phase emulsification dispersion method using a specific polysaccharide as an emulsification dispersant without using a surfactant for emulsification dispersion (Patent Literature). 8). However, there is still no way to suppress the increase in the viscosity or hardness of the cosmetic without impairing the feeling of use, and these improvements are strongly desired.

  The method for producing a cosmetic composition of the present invention is (I) a method for producing a cosmetic composition containing water, polysaccharides and polyhydric alcohols, and (A) at least one of glucose, glucuronic acid and rhamnose. Constituent monosaccharides, polysaccharides containing fucose and / or rhamnose or mannose and / or glucuronic acid in the side chain, (B) polyhydric alcohol, if necessary, emulsifying dispersant and emulsified dispersing component mixed (II) (C) water-soluble acrylic acid polymer, (D) water-soluble (meth) acrylic acid- (meth) acrylic acid ester copolymer, and then (E) base Or (E) a basic substance is added, and then (C) a water-soluble acrylic acid polymer, (D) a water-soluble (meth) acrylic acid- (meth) acrylic acid ester copolymer Add and mix A method for producing a cosmetic composition, characterized in and. When preparing the emulsified dispersion of the emulsified dispersion component, emulsification dispersion may be performed while heating.

  Component (A) is a polysaccharide that is sufficiently dissolved or dispersed in water in a cosmetic composition, but generally it is difficult to dissolve or disperse in water. Therefore, component (A) is dispersed in water in advance using a mixer or the like. May be used. Further, in order to improve the solubility and dispersibility of the component (A), the component (A) may be used by being previously wetted with a lower alcohol such as methanol, ethanol, isopropyl alcohol or the like. At this time, the component (A) is preferably used as a polysaccharide having a particle structure, and more preferably used as a single particle polysaccharide. The component (A) having a particle structure is prepared by dissolving (or dispersing) in water by applying a shearing force to the component (A) by using a dissolving device such as a homogenizer, a disperser, or a disperser mixer. To obtain. Furthermore, in order to obtain a single particle of the component (A), the shearing force of a homogenizer, a disperser, or a disperser mixer is operated at a tip speed of 0.5 m / s or more, preferably 0.9 m / s or more. If the tip speed is less than 0.5 m / s, the component (A) may not be sufficiently formed into single particles. By using the component (A) having a particle structure, the component (A) having a particle structure surrounds the emulsified and dispersed component (functional oily base and / or functional granule) and adheres in layers. An intermediate layer is formed between water and the emulsified dispersion component to form a three-phase emulsification dispersion system consisting of “water phase (solvent) —intermediate layer containing component (A) having a particle structure—emulsified dispersion phase”. Thus, a cosmetic composition having excellent thermal stability and stability over time can be obtained. More preferably, a three-phase emulsified dispersion system is formed as a polysaccharide having a particle structure in which the component (A) is made into single particles.

  In addition, as a method for preparing a cosmetic composition using the component (A) having a particle structure, water and the component (A) are mixed in advance, and a shearing force is applied by a homogenizer, a disperser, a disperser mixer, etc. After preparing the component (A) aqueous solution (or aqueous dispersion), the emulsified and dispersed components are mixed and stirred in the component (A) aqueous solution to create a three-phase emulsion dispersion system, ripen and homogenize There is also a method for producing the cosmetic composition of the present invention. In this case, the concentration of the component (A) aqueous solution is usually 0.01% to 0.8% by weight, preferably 0.05% to 0.2% by weight. If the concentration of the aqueous solution of the component (A) is less than 0.01% by weight, the amount of the component (A) may not be sufficient when the cosmetic composition is prepared, and the expected effect of the present invention may not be obtained. When the concentration of the aqueous solution (A) exceeds 0.8% by weight, the aqueous solution of the component (A) becomes viscous, the handleability is inferior, and the workability may be lowered.

  The average particle size of the component (A) having a particle structure is preferably 8 nm to 500 nm. When the average particle size of the component (A) is smaller than 8 nm, the suction action due to van der Waals force is reduced, and the component (A) May become difficult to adhere to the surface of the emulsified and dispersed component. Moreover, when the average particle diameter of (A) component is larger than 500 nm, it may become impossible to maintain a stable emulsion.

  The mixing ratio of the component (A) and the emulsified and dispersed component is 1:50 to 1: 1000 as a weight ratio, and preferably 1: 100 to 1: 500. Outside this range, an emulsified and dispersed state for obtaining the effects of the present invention may not be obtained.

  The blending amount of the component (A) may be appropriately determined in consideration of the degree of stability over time of the viscosity and hardness of the intended cosmetic composition, and cannot be uniformly determined. On the other hand, it is 0.001% to 1% by weight, preferably 0.01% to 0.5% by weight, and more preferably 0.05% to 0.2% by weight.

  (B) The addition time of a component is not specifically limited, When preparing an emulsified dispersion system by adding simultaneously with (A) component and an emulsified dispersion component, emulsification of (A) component and an emulsified dispersion component Either of them may be used when added after preparation of the dispersion.

  Although the addition method of (C) component and (D) component is not specifically limited, Since (C) component and (D) component require time to melt | dissolve in water comparatively, aqueous dispersion (or aqueous solution) previously ) Is preferred. The concentration in that case is usually about 0.05% to 2% by weight.

  In the method for producing a cosmetic composition of the present invention, the addition order of the component (E) is added after the emulsified dispersion of the cosmetic composition containing the component (A) and the component (B) is formed. Yes, avoid simultaneous addition with (C) component and (D) component, add (C) component and (D) component and uniformly disperse, or (C) component and (D) component It is preferable to add (E) component and disperse | distribute uniformly before adding. When the (E) component, the (C) component, and the (D) component are added simultaneously, the effects of the present invention may not be sufficiently obtained. The addition method of the addition (E) component is not particularly limited, and there are a direct addition method and a method of diluting and adding to water or a water-soluble solvent, and any of them may be used. As the water-soluble solvent in the method of diluting and adding to the water-soluble solvent, one or more kinds of methanol, ethanol, dioxane, acetone, ethylene carbonate and the like can be used. The dissolution concentration of the component (E) may be appropriately determined in consideration of the solubility of the component (E) in the water-soluble solvent.

  For the purpose of improving the viscosity and hardness stability of a cosmetic composition, various methods for combining a plurality of water-soluble polymers such as polysaccharides to expect a synergistic effect have been widely known. In general, a water-soluble polymer tends to crystallize with time and the viscosity of the aqueous solution tends to decrease. In particular, it is known that the tendency appears remarkably at high temperatures. In addition, polyvalent alcohols such as glycerin are added to general cosmetics for various purposes. Polyhydric alcohols tend to form strong hydrogen bonds with water and polysaccharides. As a result, the thixotropic properties of the cosmetic composition are lowered, and the initial product viscosity at the time of production of the cosmetic composition is reduced. Hardness increases.

  The present invention provides a polysaccharide (A) component specific to a cosmetic composition containing water, an emulsified and dispersed component (functional oil base and / or functional granule) and a polyhydric alcohol, (C) component and By adding (meth) acrylic acid polymer of component (D) and basic substance of component (E), these preferentially form hydrogen bonds with polyhydric alcohol, and polyhydric alcohol and polysaccharide. It is predicted that the stability of viscosity and hardness will be improved by significantly hindering and reducing the hydrogen bond between them. In particular, the polysaccharide of the general formula (1) is sterically hindered by the side chain of rhamnose or fucose having a hydrophobic group at the 6th position, and prevents crystallization by preventing the main chain from approaching in an aqueous solution. And exhibits excellent viscosity stability at high temperatures. Such facts could not be predicted from the knowledge obtained in the past.

[Viscosity stability test]
After preparing the cosmetic compositions of Examples 1 to 8 and Comparative Examples 1 to 9, the mixture was allowed to stand for 1 day, and the rotational speed was changed using a B-type viscometer (rotor No. 3) at a measurement temperature of 25 ° C. The viscosity at each rotational speed was measured. In the viscosity measurement, the rotor rotation speed was set to 6 rpm, the viscosity after rotating for 1 minute from the start of rotation of the rotor was measured. The later viscosity was measured. The thixotropic property was defined and calculated as follows.
[Thixotropic property] = (α / β) × 100
α: Viscosity at rotor rotation speed 60 rpm (mPa · s)
β: Viscosity at rotor rotation speed 6 rpm (mPa · s)
After measuring the viscosity, it was allowed to stand indoors at 4 ° C., 30 ° C. and 50 ° C., and the viscosity was measured after 3 months. Further, the thixotropic property (x) after 1 day of preparation was compared with the thixotropic property (y) after 3 months, and the change rate (%) was calculated according to the following formula. The smaller the rate of change (%), the better.
[Change rate (%)] = (x / y) × 100
x: thixotropic value 1 day after preparation y: thixotropic value results after 3 months are summarized in Tables 9 to 11.

  In the cosmetic composition of the present invention, the change rate (%) of thixotropic property is almost unchanged in the range of 96% to 116%. However, in the conventional cosmetic compositions (Comparative Examples 1 to 9), the change rate (%) of thixotropic property is 150% or more, and the thixotropic property decreases with the passage of time, resulting in an increase in viscosity. I understand that.

[Hardness test]
The creams 2 to 7 prepared in Examples 2 to 4 and Comparative Examples 2 to 5 were allowed to stand indoors at 4 ° C., 30 ° C., and 50 ° C. the next day, and the hardness after 3 months was measured. The hardness is measured by filling a cosmetic composition in a 30 ml container, making a sample, closing the lid and allowing it to stand overnight at 25 ° C., and attaching a rheometer (FUDOH RHEO METER) and a 5φ adapter for compression / elasticity. The hardness (g) was measured at a stage speed of 6 cm / min. The hardness after 1 day of preparation of the cosmetic composition was compared with the hardness after 3 months of standing and evaluated as the rate of change. The smaller the rate of change, the better.
[Change rate (%)] = (a / b) × 100
a: Hardness after one day of preparation (g)
b: Hardness after 3 months (g)
The results are summarized in Table 12.

  The creams 1 to 3 of the present invention have almost no change in hardness over time, but the creams 4 to 7 according to the conventional method have increased in hardness by 150% to 200% after 3 months after preparation, and the change in hardness over time It can be seen that

[Sensory test of cosmetic composition (usefulness evaluation)]
Creams 2 to 7 (Examples 2 to 4 and Comparative Examples 2 to 5) that were allowed to stand for 1 day after preparation, and creams 2 that were prepared 3 months ago, placed in a 5 ° C. incubator, and allowed to stand for 3 consecutive months -7 (Examples 2 to 4 and Comparative Examples 2 to 5) were subdivided into 10 sets of jars each having the same appearance so that they could not be distinguished from each other. Next, select 10 panelists, 2 from each age group from the 10s to the 50s, and each person takes an appropriate amount of cream with their fingers and then stretches them on the back of both hands. The sensory evaluation of “smoothness” was performed. The evaluation criteria for “hand feeling” and “smoothness” were as follows. The results are shown in Table 13.
・ Evaluation criteria of “hand-feel” ○: Evaluated when 8 or more out of 10 people can take smoothly Δ: Evaluated that 5-7 out of 10 people can take smoothly.
X: It is evaluated that 4 or less of 10 people can take smoothly.
Evaluation criteria for “smoothness” ○: 8 or more out of 10 people evaluated that they had a smooth feel Δ: 5 to 7 out of 10 people evaluated that they had a smooth feel.
X: 4 or less of 10 people evaluated that there was a smooth feel.

The creams 1 to 3 of the present invention maintain a good hand feeling over a long period of 1 day and 3 months after production without affecting the smoothness after 1 day and 3 months after production. On the other hand, the creams 4 to 7 according to the conventional method maintain the smoothness after 1 day of production and 3 months after production, but it is understood that the feeling of taking after 1 day of production is lost after 3 months.
