Abstract
The present invention relates to a powdery solid cosmetic comprising fatty acid calcium salt particles having 12 to 22 carbon atoms of fatty acid and an oily component comprising a polar oil having an IOB of 0.01 or more, wherein the fatty acid calcium salt particles have a median particle diameter of 4.0 to 15.0 [ mu ] m, a particle size description value A expressed by a specific formula satisfies the relation of A.ltoreq.2.0, and an average thickness of 350 to 800nm.
Description
Technical Field
The present invention relates to a powder solid cosmetic, and more particularly, to a powder solid cosmetic excellent in impact resistance.
Background
Powder solid cosmetics represented by foundations and eye shadows are produced by adding an oily component to a powder component such as a pigment, and filling the powder component into a container such as a middle plate. The powder solid cosmetic is excellent in portability, and on the other hand, the following problems may occur: the molded product is broken by an impact such as vibration or dropping, and is released from the container.
In addition, as one of methods for making the appearance of cosmetics look attractive, it is known to compound a glittering powder (pearlizing agent). The brightening powder is: plate-like or spherical powder having an interference color, a pearl luster, or a metallic luster, which is generally used in the cosmetic field for expressing luster. However, there is a case where the impact resistance of the powder solid cosmetic is lowered due to the blending of the shining powder.
In order to improve the moldability and impact resistance of a powder solid cosmetic, it is known to blend a metal soap. For example, patent document 1 describes: a solid powder cosmetic having excellent usability and impact resistance by containing metal soap particles of a specific particle size.

ADVANTAGEOUS EFFECTS OF INVENTION

Detailed Description
The cosmetic of the present invention contains specific fatty acid calcium salt particles as a metal soap.
The fatty acid calcium salt particles of the present invention have a carbon number of 12 to 22. By setting the carbon number of the fatty acid to 12 or more, excellent usability of the cosmetic can be imparted. On the other hand, the carbon number is 22 or less, so that the fatty acid can be easily obtained industrially, and the productivity is high. From the viewpoint of impact resistance, the carbon number of the fatty acid is preferably 12 to 18, more preferably 14 (i.e., the fatty acid calcium salt is calcium myristate).
The fatty acid is not particularly limited as long as it is a fatty acid having 12 to 22 carbon atoms. That is, the fatty acid may be either a natural fatty acid or a synthetic fatty acid, a saturated fatty acid or an unsaturated fatty acid, or a linear or branched fatty acid. Further, the fatty acid may have a functional group such as a hydroxyl group, an aldehyde group, or an epoxy group in its structure. The fatty acid is preferably a linear saturated fatty acid.
Examples of the fatty acid include lauric acid, myristic acid, myristoleic acid, palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, arachic acid, behenic acid, erucic acid, hydroxystearic acid, and epoxystearic acid, and among these, myristic acid is preferable. When a mixed fatty acid is used, the myristic acid content in the fatty acid is preferably 50% or more, more preferably 60% or more, and still more preferably 70% or more.
The fatty acid calcium salt particles of the present invention have a volume-based median particle diameter (D50) of 4.0 to 15.0. Mu.m. The particle diameter is excellent in impact resistance. The median particle diameter of the fatty acid calcium salt particles is preferably 5.0 to 12.0. Mu.m, more preferably 6.0 to 10.0. Mu.m. The particle size can be measured by the MICROTRAC laser diffraction method in the same manner as the particle size description value a described later.
Regarding the fatty acid calcium salt particles in the present invention, the particle size description value A represented by the following formula (1) satisfies the relationship of A.ltoreq.2.0.
Particle size description A= (D90-D10)/D50 … type (1)
(wherein, D50 is more than or equal to 4.0 and less than or equal to 15.0)
D10: 10% cumulative particle diameter (μm) in volume basis of fatty acid calcium salt particles
D50: median particle diameter (μm) in volume basis of fatty acid calcium salt particles
D90: 90% cumulative particle diameter (μm) in volume basis of fatty acid calcium salt particles
By narrowing the particle size distribution of the fatty acid calcium salt particles, the fatty acid calcium salt particles can be uniformly present in cosmetics, and impact resistance can be easily exhibited.
In the present invention, the particle size description value a is calculated from the particle size measured by the MICROTRAC laser diffraction method. By setting the particle size description value a to 2.0 or less, the particle size of the fatty acid calcium salt particles present in the cosmetic becomes uniform, the dispersibility of the cosmetic is good, the productivity is not lowered, and the cosmetic having a target touch can be produced. The particle size description value A more preferably satisfies the relationship of 0.5.ltoreq.A.ltoreq.1.8. When the relation of A being more than or equal to 0.5 and less than or equal to 1.8 is satisfied, the action and effect of the invention can be obtained more stably. If the particle size description value A is 0.5 or more, the yield is not lowered, and the production can be industrially stably performed.
In the above formula (1), when the cumulative curve is obtained by setting the total volume of the powder aggregate to 100%, the particle diameters at the points where the cumulative curve is 10%, 50% and 90% are referred to as 10% cumulative particle diameter (D10), 50% median particle diameter (D50; median particle diameter) and 90% cumulative particle diameter (D90) (μm), respectively.
The particle size description value a can be adjusted by appropriately adjusting the concentration of the fatty acid basic compound salt, the temperature at which the fatty acid basic compound salt reacts with the calcium salt, and the dropping rate at which the aqueous solution containing the calcium salt is dropped into the aqueous solution containing the fatty acid basic compound salt, respectively, in the method for producing fatty acid calcium salt particles described later. The substance having a broad particle size distribution, in other words, a large value of the particle size description value a can be adjusted by classifying the substance using a 100-mesh, 200-mesh, 330-mesh sieve or the like in the subsequent treatment.
The MICROTRAC laser diffraction method used herein is a method of obtaining a particle size distribution by using scattered light obtained by irradiating particles with laser light. In the present invention, the following wet-type measurement is set: when an organic solvent in which the fatty acid calcium salt particles are not dissolved, for example, an organic solvent such as ethanol or isopropanol is circulated, the sample is directly introduced. In the present invention, the particle size of the object to be measured is in the range of 0.1 μm to 200 μm, and the value represented by the above formula (1) is defined as the particle size description value A. In the present invention, for example, MICROTRAC MT-3000 manufactured by Nikkin corporation may be used for measurement.
The fatty acid calcium salt particles in the present invention have an average thickness of 350 to 800nm. By providing the above thickness, the cosmetic composition can be easily dispersed even under the condition (manufacturing method) of being gently mixed into the cosmetic composition, can be easily and uniformly applied to the skin as a cosmetic composition, and can also improve the touch feeling after application. Further, the above thickness gives sufficient impact resistance when added to cosmetics. The average thickness of the particles is more preferably 400 to 700nm. If 400 to 700nm is satisfied, the operational effect of the present invention can be obtained more stably.
The thickness of the particles means: the length of the side surface when the largest surface area of the fatty acid calcium salt particles is the front surface is set as the length value.
The fatty acid calcium salt particles of the above specific thickness are described in detail in the following description of the production method, but can be obtained as follows: when the aqueous solution containing a calcium salt prepared by the metathesis reaction and the aqueous solution containing a fatty acid alkali compound salt are mixed, the aqueous solution containing a calcium salt is slowly dropped into the aqueous solution containing a fatty acid alkali compound salt at an appropriate rate.
The shape of the fatty acid calcium salt particles in the present invention is not particularly limited, but is preferably plate-shaped.
The powder solid cosmetic of the present invention is excellent in impact resistance by containing the fatty acid calcium salt particles having the above specific properties. This is presumably because: in particular, by narrowing the particle size distribution of the fatty acid calcium salt particles, which satisfies the relation that A.ltoreq.2.0, the dispersibility is good and the particles are uniformly distributed in the molded article, so that the strain deviation at the time of impact application is small, and the stress relaxation of the whole agglomerate is easy. It can be considered that: as a result, the fatty acid calcium salt particles uniformly dispersed in the molded article can firmly bond the powders to each other, and can disperse the impact stress, thereby improving the impact resistance.
The content of the fatty acid calcium salt particles in the powder solid cosmetic of the present invention is preferably 0.01 to 30% by mass, more preferably 0.1 to 20% by mass, and particularly preferably 1 to 10% by mass, from the viewpoint of impact resistance.
The above-mentioned specific fatty acid calcium salt particles can be produced by a double decomposition method in which a fatty acid basic compound salt obtained by reacting a monovalent basic compound with a fatty acid having 12 to 22 carbon atoms and a divalent calcium salt are reacted in an aqueous solution.
Examples of the monovalent basic compound as a raw material of the fatty acid basic compound salt include hydroxides of alkali metals (sodium, potassium, etc.); amines such as ammonia, monoethanolamine, diethanolamine and triethanolamine. From the viewpoint of high solubility in water in the production of the fatty acid alkali compound salt, alkali metal hydroxides such as sodium and potassium are preferable.
The fatty acid basic compound salt used in the present invention is obtained by reacting a monovalent basic compound with a fatty acid at a temperature generally higher than the melting point of the fatty acid and to such an extent that the fatty acid does not decompose, preferably at 100 ℃ or lower, more preferably at 50 to 100 ℃, still more preferably at 60 to 95 ℃, particularly preferably at 70 to 95 ℃.
The fatty acid calcium salt particles of the present invention can be obtained, for example, by reacting the fatty acid basic compound salt obtained as described above with a calcium salt in an aqueous solution. Specifically, the calcium salt is a salt of inorganic calcium with an inorganic acid or an organic acid. Examples of the calcium salt include calcium chloride and calcium acetate. In particular, calcium chloride is preferable from the viewpoint of high solubility in water and efficient reaction with the fatty acid alkali compound salt.
For the reaction of the fatty acid basic compound salt with the divalent calcium salt, specifically, it can be carried out by the following means: after preparing an aqueous solution containing a calcium salt and an aqueous solution containing a fatty acid basic compound salt, respectively, they are mixed to perform. For example, the reaction is carried out by adding an aqueous solution containing a calcium salt to an aqueous solution containing a fatty acid alkali compound salt, or adding both to another reaction tank.
When an aqueous solution containing a fatty acid basic compound salt is mixed with an aqueous solution containing a calcium salt, for example, if the aqueous solution containing a calcium salt is added to the aqueous solution containing a fatty acid basic compound salt at one time, the shape of the obtained fatty acid calcium salt particles may become uneven, and the particle size distribution may be widened. Therefore, in the present invention, it is preferable to slowly drop an aqueous solution containing a calcium salt into an aqueous solution containing a fatty acid alkali compound salt at an appropriate rate. The drop acceleration is preferably 0.005 to 0.8 mol/mol, more preferably 0.01 to 0.5 mol/mol, per unit time. By mixing at this dropping rate, the exchange reaction between the base and the calcium can be performed gently, and the fatty acid calcium salt particles having an appropriate thickness can be obtained. By setting the speed to 0.005 mol/mol or more, the thickness of the particles is not thinned, and the fatty acid calcium salt particles having a desired thickness can be obtained. On the other hand, by setting the drop rate per unit time to 0.8 mol/mol or less, the particles of the fatty acid calcium salt are uniform in shape and become a desired thickness, and therefore, the particle size is not uniform, and it is preferable.
The unit "mol/mol" of the calcium salt to be added dropwise is the number of moles of the calcium salt to be added dropwise relative to 1 mole of the fatty acid-based compound.
The concentration of the fatty acid basic compound salt at the time of producing the fatty acid calcium salt is usually 1 to 20% by mass, preferably 5 to 15% by mass, from the viewpoint of productivity of the fatty acid calcium salt and from the viewpoint of handling of the aqueous solution containing the fatty acid basic compound salt or the obtained fatty acid calcium salt slurry. If the concentration of the fatty acid basic compound salt is 1 mass% or more, the productivity of the fatty acid calcium salt is good, and it is preferable. If the content is 20% by mass or less, the viscosity of the aqueous solution containing the fatty acid basic compound salt or the obtained fatty acid calcium salt slurry does not increase, and a uniform reaction can be performed. The concentration of the calcium salt in the liquid containing the calcium salt is usually 10 to 50% by mass, preferably 10 to 40% by mass, from the viewpoint of the productivity of the fatty acid calcium salt and from the viewpoint of the handleability of the aqueous solution containing the fatty acid basic compound salt or the obtained fatty acid calcium salt slurry.
The reaction of the fatty acid basic compound salt with the calcium salt is carried out under temperature conditions generally carried out by those skilled in the art in view of the solubility of the fatty acid basic compound salt. Preferably 50 to 100℃and more preferably 60 to 95 ℃. If the reaction temperature is 50 ℃ or higher, the reaction rate of the fatty acid basic compound salt and the calcium salt is good.
For the purpose of stabilizing the fatty acid calcium salt slurry at the time of the reaction of the fatty acid basic compound salt with the calcium salt and improving the productivity of the fatty acid calcium salt, it is preferable that a triblock ether having a structure (EO-PO-EO) obtained by sandwiching a polyalkylene glycol-based ether, particularly an oxypropylene segment, with an oxyethylene segment is present in the fatty acid calcium salt slurry. The content of the polyalkylene glycol ether in the fatty acid calcium salt slurry is usually 0.01 to 5 parts by mass, preferably 0.05 to 2 parts by mass, relative to 100 parts by mass of the fatty acid basic compound salt. The polyalkylene glycol ether may be present in the reaction system before the monovalent alkali compound is reacted with the fatty acid, or may be present in the reaction system before the salt of the fatty acid alkali compound is reacted with the calcium salt.
By the method, a dehydrator, a filter press and the like are utilized for separation, and a fatty acid calcium salt filter cake with reduced water content is obtained. The fatty acid calcium salt cake having a reduced water content is dried by a rotary dryer, an air-flow dryer, a ventilated shelf dryer, a spray dryer, a fluidized bed dryer, or the like.
In the present invention, the drying of the fatty acid calcium salt cake must be carried out at a temperature of (. Alpha. -40). Ltoreq.α.ltoreq.α+5). Ltoreq.c with respect to the water-containing evapotranspiration peak top temperature (. Alpha.C) of the produced fatty acid calcium salt. Here, the peak top temperature of the water-containing evaporation means: the peak of the peak in the temperature range from which residual water that cannot be removed by the drying starts to be separated, which is contained in the fatty acid calcium salt, for example, contains a water vapor emission peak top temperature of 110.3 ℃ in a thermal absorption diagram of calcium myristate based on differential thermal analysis (DSC). The specific drying temperature varies depending on the kind of the obtained fatty acid calcium salt, and is, for example, 115 ℃ or lower in the case of calcium myristate. If the drying treatment is performed at a temperature higher than 115 ℃, the fine particles are coagulated, and the thickness of the particles tends to be large. On the other hand, when the drying treatment is performed at a temperature lower than 70 ℃, the drying property is lowered and a large amount of moisture remains in the compound.
The fatty acid calcium salt particles are obtained by the above-described method.
