JP5917293B2 - Al-containing yellow plate-like iron oxide pigment, method for producing the same, and cosmetics containing the same - Google Patents

Description

  The present invention relates to a plate-like iron oxide pigment having a high yellowness tone, a method for producing the same, and a cosmetic containing the iron oxide pigment.

  Conventionally, in makeup cosmetics such as foundations and lipsticks, it covers the reddish face, dullness, spots, freckles, etc. caused by the skin, and produces a skin with a uniform and beautiful appearance. The skin tone is changed by adding colorants such as other inorganic pigments and organic pigments.

As the colorant, iron oxide pigments having high safety and high coloring power and hiding power are often used, yellow being goethite (α-FeOOH) and red being hematite (α-Fe ₂ O _3). ) And black are magnetite (Fe ₃ O ₄ ). However, since these iron oxides have a rod-like or spherical shape, when they are applied to the skin using a foundation containing the iron oxide, they feel squeaky as if they have stopped on the skin, and there is no smooth feeling. May end up. In order to solve this problem, methods of making the particle shape plate-like and attempts to combine iron oxide with plate-like substrate particles have been studied.

  For example, plate-like iron oxide (AM-200 manufactured by Titanium Industry) described in JIII Journal of Technical Disclosure No. 2007-500909 (Non-patent Document 1) has a very smooth feel when applied to the skin. It has red iron oxide. In addition, since the scale-like iron oxide particles having a magnetite structure described in JP 2010-83727 A (Patent Document 1) are plate-shaped, they are black and have a very smooth feel when applied to the skin. It is iron oxide. Since these are red or black, the deterioration of the feel is inevitable when the rod-shaped yellow iron oxide conventionally used for toning is used together, and the development of yellow-based plate-like iron oxide is desired. It was.

  JP-A-8-12337 (Patent Document 2) describes a yellow luster pigment having the form of δ-FeOOH. Since δ-FeOOH is plate-shaped, it feels good when it is applied, such as stretch and slip, but the yellowness is not sufficient.

  Japanese Patent Application Laid-Open No. 2000-265154 (Patent Document 3) describes a composition in which iron oxide is coated on plate-like barium sulfate. When iron oxide is peeled off from the particles, the smooth feel is deteriorated and color separation may occur. Therefore, the performance is not sufficient.

  An object of the present invention is a yellow plate-like iron oxide that can be smoothly applied to the skin when used in cosmetics, has no squeaky or rough feeling on the skin, and can produce a natural skin feeling It is to provide a pigment, a method for producing the same, and a cosmetic containing the iron oxide pigment.

As a result of repeated studies aimed at providing yellow iron oxide that can be smoothly applied to the skin when blended in cosmetics, the present inventors have found that 100 wt.% Of Fe in the formation reaction of δ-FeOOH. The plate-like iron oxide produced by containing 0.1 to 10.0 parts by weight of Al with respect to parts, the average particle size in the plate surface direction being 0.1 to 5.0 μm, with respect to the plate surface The average thickness in the normal direction is 20 to 100 nm, and the average plate ratio (hereinafter, the term “average plate ratio” in the present specification is “average particle diameter in plate direction: relative to plate surface of particles”. "Mean thickness in the normal direction") is mica-like or plate-like in the range of 5: 1 to 100: 1, and the phase angle tan ^-1 (b / a) of the powder color is 50 ° or more The cosmetics containing Al-containing yellow iron oxide with a yellowness of However, the present invention has been completed.

The present invention contains 0.1 to 10.0 parts by weight of Al with respect to 100 parts by weight of Fe, the average particle diameter in the plate surface direction is 0.1 to 5.0 μm, and the normal direction to the plate surface The average thickness is 20 to 100 nm, the average plate ratio is mica or plate in the range of 5: 1 to 100: 1, and the phase angle tan ⁻¹ (b / a) of the powder color An Al-containing yellow plate-like iron oxide pigment characterized by having an angle of 50 ° or more is provided.

The present invention also includes a step of forming a ferrous hydroxide slurry by adding an aqueous alkali solution having a neutralization equivalent or more to a ferrous salt aqueous solution in an inert gas atmosphere. Production of Al-containing yellow plate-like iron oxide pigments comprising a step of aging at -100 ° C and further cooling to 50 ° C or lower, and a step of oxidizing the aged ferrous hydroxide slurry using an oxidizing agent It is a method, Comprising: In any of the said alkaline aqueous solution, ferrous salt aqueous solution, or the ferrous hydroxide slurry formed by making these react, 0.1-10.0 in conversion of Al with respect to 100 weight part of Fe There is provided a production method characterized by adding a part by weight of a water-soluble aluminum compound.
Moreover, this invention provides the cosmetics which mix | blended said Al containing yellowish plate-shaped iron oxide particle.

  An important means in the present invention is to contain 0.1 to 10.0 parts by weight of Al with respect to 100 parts by weight of Fe before the plate-like iron oxide is formed. Even if it is contained, good yellowness cannot be obtained. When Al is contained before the plate-like iron oxide is formed, if the Al content is less than 0.1 parts by weight, the plate-like ratio becomes small and the color tone becomes reddish. On the other hand, if the Al content exceeds 10.0 parts by weight, the average particle size in the plate surface direction becomes smaller than 0.1 μm, and a squeaky feeling is exhibited when spreading on the skin, which is not preferable.

  The reason why a plate-like iron oxide having a high yellowness can be obtained by containing 0.1 to 10.0 parts by weight of Al with respect to 100 parts by weight of Fe before the plate-like iron oxide is formed is that Al This is presumably because, in the crystal growth of the plate-like iron oxide particles, the growth in the thickness direction is suppressed and the plate-like ratio of the iron oxide to be produced is improved. In the case of plate-like iron oxide, as the thickness increases, the amount of light absorbed on the long wavelength side increases and becomes red, and the yellowness decreases. Moreover, when Al addition amount exceeds 10.0 weight part, since said growth inhibitory effect is too strong, it stops crystal growth and the average particle diameter of a plate surface direction reduces.

  When the Al-containing yellow plate-like iron oxide of the present invention is blended in cosmetics, especially makeup cosmetics, it can be applied smoothly to the skin, and there is no squeaky or rough feeling on the skin, and a good yellow color By having a degree, there is an effect of producing a natural skin feeling.

2 is a scanning electron micrograph showing the particle structure of Al-containing yellow plate iron oxide obtained in Example 1. FIG.

  Hereinafter, the Al-containing yellow plate-like iron oxide pigment of the present invention, a method for producing the same, and a cosmetic containing the iron oxide pigment will be described in detail.

The Al-containing yellow plate-like iron oxide pigment of the present invention contains 0.1 to 10.0 parts by weight of Al with respect to 100 parts by weight of Fe, and the average particle size in the plate surface direction is 0.1 to 5.0 μm. The average thickness in the normal direction with respect to the plate surface is 20 to 100 nm, the average plate ratio is in the range of 5: 1 to 100: 1, exhibits a mica shape or a plate shape, and has a powder color The phase angle tan ⁻¹ (b / a) is 50 ° or more.
(Average particle diameter, thickness, average plate ratio in plate surface direction)

The average particle diameter in the plate surface direction, the average thickness in the direction normal to the plate surface, and the average plate ratio of the Al-containing yellowish plate-like iron oxide particles of the present invention are 70 pieces from the scanning electron micrograph. It is a value obtained by measuring individual in-plane length, thickness and plate ratio of particles and averaging them.

When the average particle size in the plate surface direction is smaller than 0.1 μm, it is not preferable because a squeaky feeling is exhibited when spreading on the skin. Further, if the average particle size in the plate surface direction is larger than 5.0 μm, the adhesiveness to the skin becomes weak and it is difficult to attach the makeup, which is not preferable.

An average plate ratio of less than 5: 1 is not preferable because the color tone becomes reddish. On the other hand, when the average plate ratio is larger than 100: 1, the particles are easily crushed and the stability of the color tone is deteriorated.
(Analysis of Al content)

The amount of Al in the Al-containing yellow plate-like iron oxide pigment of the present invention was measured using a Rigaku Simultix 10 type fluorescent X-ray analyzer.
(Measurement of phase angle of powder color measurement)

5 g of the iron oxide powder weighed out is placed in an aluminum ring, pressurized to 40 kg / cm ² with a hydraulic molding machine to produce pellets, and L, a, b is measured. The phase angle is calculated by tan ⁻¹ (b / a). If the phase angle is less than 50 °, the reddish color becomes strong and cannot be called yellow.
(Method for producing Al-containing yellow plate-like iron oxide)
The method for producing the Al-containing yellowish plate-like iron oxide of the present invention will be described in detail.

  A ferrous hydroxide is produced by adding an aqueous alkali solution having a neutralization equivalent or more to a ferrous salt aqueous solution set at a predetermined temperature in an inert gas atmosphere. In this case, 0.1 to 10.0 parts by weight in terms of Al with respect to 100 parts by weight of Fe, in any of the above alkaline aqueous solution or ferrous salt aqueous solution or ferrous hydroxide produced by reacting these. Add water soluble aluminum compound. As the water-soluble aluminum compound, aluminum sulfate, aluminum chloride, aluminum nitrate, sodium aluminate or the like is used.

  Examples of ferrous salts that can be used in the present invention include ferrous chloride, ferrous sulfate, and ferrous nitrate. Moreover, hydroxides such as sodium hydroxide, potassium hydroxide, and ammonium hydroxide, carbonates such as sodium carbonate, potassium carbonate, and ammonium carbonate, and ammonia gas can be used as the alkali source of the alkaline aqueous solution. However, when the neutralization temperature is high, ammonia-based compounds are volatilized, so it is preferable to use a hydroxide.

  The alkali addition amount with respect to the ferrous salt aqueous solution needs at least neutralization equivalent or more, and preferably 1.02 to 10 times equivalent. If it is 10 times equivalent or more, not only the product is not affected, but also the cost is wasted.

  Next, the iron hydroxide slurry obtained by neutralization is aged at the neutralization temperature or higher. The aging temperature is preferably 60 to 100 ° C. When the temperature is less than 60 ° C., the average particle size in the plate surface direction becomes small, and a squeaky feeling is exhibited when spreading on the skin, which is not preferable. Even when the temperature exceeds 100 ° C., the target Al-containing yellowish plate-like iron oxide of the present invention can be obtained, but this is not preferable because it becomes industrially inefficient.

  The slurry after aging is cooled to 50 ° C. or lower, and an oxidizing agent is added to oxidize. When oxidation is performed at 50 ° C. or higher, a form other than a plate shape is generated, which is not preferable. The added amount of the oxidizing agent is required to be at least an oxidation equivalent or more, but is preferably about 1.1 to 1.5 times equivalent in terms of cost. As the oxidizing agent, peroxides such as hydrogen peroxide and sodium peroxide, perchlorates such as potassium perchlorate and permanganates such as potassium permanganate can be used.

The oxidized product is filtered and washed to remove miscellaneous salts and then dried. The drying temperature is not particularly limited, but if it exceeds 150 ° C., it is not preferable because it dehydrates and discolors.
