Definitions
- the present invention relates to starch particles surface-treated with vegetable wax.
- plastics are used in various industries. Synthetic polymers are often developed for long-term stability and do not degrade in the natural environment. As a result, various environmental problems have arisen. For example, plastic products that have flowed into the water environment have accumulated over a long period of time, greatly affecting marine and lake ecosystems. In recent years, microplastics with a length of 5 mm or less to nm level have become a big problem. Examples of microplastics include fine particles contained in cosmetic products, small lumps of plastic resin before processing, and substances that become finer as large products float in the sea.
- plastic particles for example, polyethylene particles
- plastic particles have a low true specific gravity, they are difficult to remove at sewage treatment plants and easily flow into rivers, oceans, ponds, and the like.
- plastic particles tend to adsorb chemical substances such as insecticides, which may affect the human body through bioaccumulation. This has been pointed out by the United Nations Environment Program, etc., and various countries and industry groups are considering regulations.
- microplastics as synthetic polymers.
- biodegradable substances such as cellulose and starch derived from nature should not be regarded as microplastics.
- the cellulose in the patent document is a trans-polysaccharide whose constituent units are glucose molecules, and does not dissolve in water. Therefore, it is believed that cellulose is not highly degradable in nature. The definition of biodegradability is still unclear, and there remains concern that cellulose will become a regulated substance.
- the object of the present invention is to realize particles with excellent tactile properties and water repellency using a water-soluble material.
- coated particles are formed by treating the surface of starch particles with vegetable wax.
- starch and cellulose are polysaccharides having glucose as a constituent unit, but both are isomers. That is, starch is cis-type and cellulose is trans-type. This difference is related to the presence or absence of water solubility and biodegradability. Cosmetics containing water-soluble starch particles are less likely to cause environmental problems, and can provide the same tactile characteristics as conventional plastic beads.
- the coated particles according to the present invention are starch particles surface-treated with rice bran wax.
- the coated particles have an average particle diameter d1 of 0.5 to 20 ⁇ m, and a maximum particle diameter d2 of less than 30 ⁇ m and within 4.0 times the average particle diameter d1.
- the vegetable wax is contained in the coated particles in an amount of 0.5-10.0% by weight.
- the method for producing coated particles according to the present invention includes the steps of preparing a dispersion liquid containing 1 to 20% by weight of starch particles, adding vegetable wax to the dispersion liquid, heating and cooling to coat the surfaces of the starch particles with plant wax. and a step of separating the coated particles from the dispersion as a solid by solid-liquid separation. At this time, it is preferable to add 0.5 to 11.0% by mass of vegetable wax based on the mass of starch particles contained in the dispersion.
- rice bran wax As the vegetable wax. Furthermore, it is preferable to use starch particles having an amylopectin content of 90% by weight or more. Also, the content of globulin, which is a protein, is preferably 0.02% by weight or less.
- a cosmetic can be produced by blending the coated particles described above.
- the present invention relates to coated particles in which vegetable wax is provided on the surface of starch particles.
- the coated particles are particles obtained by surface-treating starch particles with vegetable wax, and contain 0.5 to 10.0% by weight of vegetable wax. That is, the weight of the vegetable wax corresponds to 0.5-10.0% of the weight of the coated particles. If it is less than 0.5%, the desired water repellency cannot be imparted. If it exceeds 10.0%, the coated particles may adhere to each other to form large agglomerates. 1.0 to 5.0% is more preferred.
- the surface of the starch particles need not be completely covered with the vegetable wax, and a part of the surface of the starch particles may be exposed. A water-repellent effect is obtained if the aforementioned proportion of vegetable wax is detected with respect to the weight of the coated particles.
- the weight of vegetable wax can be quantified by infrared absorption spectrum measurement.
- the average particle diameter d1 of the coated particles is 0.5 ⁇ m or more and 20 ⁇ m or less, and the maximum particle diameter d2 is less than 30 ⁇ m and 4.0 times or less of the average particle diameter d1.
- the average particle size d1 affects the tactile properties of cosmetics. If it is less than 0.5 ⁇ m, the tactile properties such as rolling feel, durability of rolling feel, and uniform spreadability are remarkably deteriorated.
- the average particle diameter d1 is preferably 1.5 ⁇ m or more, more preferably 2 ⁇ m or more, and most preferably 5 ⁇ m or more. On the other hand, when the thickness is larger than 20 ⁇ m, a rough feeling is felt, and the soft feeling and the moist feeling are lowered.
- the average particle diameter d1 is preferably 15 ⁇ m or less, more preferably 10 ⁇ m or less.
- the maximum particle diameter d2 is 30 ⁇ m or more , the texture is felt, and the softness and moistness are lowered.
- the maximum particle size exceeds 4.0 times the average particle size, the uniform spreadability is deteriorated.
- the average particle size d1 is the median value obtained from the particle size distribution of the particles, and the largest particle size detected in the particle size distribution is the maximum particle size d2 .
- Typical vegetable waxes include rice bran wax, carnauba wax, candelilla wax, and Japan wax. Carnauba wax and rice bran wax, which have relatively high melting points, are preferred. Furthermore, rice bran wax, which is also edible, is most preferred. Rice bran wax is mainly composed of a higher alcohol ester component and a fatty acid component, and does not contain an odorous free alcohol component.
- starch particles containing 90% by weight or more of amylopectin are generally composed of amylose and amylopectin.
- Amylose has a structure in which glucose molecules are linked in a straight chain.
- Amylopectin has a structure in which amylose is branched and connected, and has a large molecular weight.
- the higher the amylose content the higher the swelling property of the starch particles, which causes stickiness when blended in cosmetics. Therefore, the content of amylose is preferably less than 10% by weight.
- the higher the amylopectin content the better. 95% by weight or more is more preferred, and 98% by weight or more is most preferred.
- the content of amylopectin can be measured by a gel filtration method, an iodine colorimetry method, a two-wavelength measurement method, or the like.
- the starch particles contain protein derived from the raw material.
- proteins globulin has a strong allergenic activity and is regarded as a causative agent of rice allergy. Therefore, the globulin content is preferably 0.10% by weight or less. 0.05% by weight or less, or even 0.02% by weight or less is suitable.
- Globulin can be reduced by enzymatically treating the source of starch granules (generally starch kernels). Other examples include immersion treatment in a saline solution, dilute acid solution, or alkaline solution, and high pressure treatment (for example, 100 to 400 Mpa). These treatments may be combined.
- the coated particles preferably have a sphericity of 0.85 or more, that is, they are spherical.
- a sphericity of 0.90 or more is particularly preferable.
- the sphericity is determined by an image analysis method from a scanning electron microscope photograph.
- the coefficient of variation (CV) of the coated particles is preferably 50% or less. If the coefficient of variation of particles exceeds 50%, uniform rolling performance may not be obtained.
- the particle variation coefficient is preferably 40% or less, particularly 30% or less. Although the smaller the particle variation coefficient, the better, it is industrially difficult to obtain particles with a narrow distribution. If it is about 3% or more, it can be produced without any particular problem.
- the vegetable wax present on the surface of the coated particles has little effect on the shape of the particles. Therefore, it is desirable that the starch particles also have the properties of the coated particles described above.
- starch particles are dispersed in a solvent to prepare a dispersion having a starch particle solid content concentration of 1 to 20% by weight (first step).
- Rice bran wax is added to the dispersion and heated. This causes the rice bran wax to dissolve in the solvent.
- second step by cooling the dispersion, the dissolved rice bran wax is deposited on the surface of the starch particles (second step).
- the dispersion is subjected to solid-liquid separation to take out the coated particles as a solid (third step).
- Starch particles prepared here can be prepared by a known method. Also, a solvent with a boiling point higher than the melting point of rice bran wax is used.
- a dispersion of starch particles is prepared.
- the solid content concentration of starch particles is adjusted in the range of 1 to 20% by weight. If the solid content concentration of the dispersion exceeds 20% by weight, the starch particles tend to aggregate. Therefore, there is a possibility that the coating state of the rice bran wax may not be uniform in the subsequent process. In that case, desired water repellency cannot be obtained. If it is less than 1% by weight, the yield of the coated particles is small and economically unsatisfactory.
- a solvent for the dispersion liquid a solvent in which rice bran wax is dissolved by heating is used. Organic solvents are preferred as solvents. In particular, alcohol solvents are preferred, and IPA (isopropyl alcohol) is suitable.
- Rice bran wax is added to this dispersion and heated to dissolve the rice bran wax in the solvent. Heat above 78°C, the melting point of rice bran wax.
- the temperature is preferably less than 90°C, but may be appropriately determined according to the solvent used. If the temperature is too low, the rice bran wax may not be melted or melted insufficiently, resulting in an uneven coating. If the temperature is 90° C. or higher, it takes a long time to heat, which is economically inefficient.
- the mass of rice bran wax to be added is preferably 0.5 to 11.0% of the mass of starch particles. If it is less than 0.5%, the desired water repellency cannot be imparted. In order to make the coated particles contain about 10% by weight of vegetable wax, it is preferable to add about 11%. However, if it exceeds 11.0%, the particles may adhere to each other to form large aggregates. 1.0 to 5.0% is more preferred.
- the rice bran wax is deposited on the surface of the starch particles. It may be cooled to a temperature at which rice bran wax precipitates, and the temperature is preferably less than 40°C. If the temperature is 40°C or higher, the dissolved rice bran wax may not precipitate sufficiently. A large amount of rice bran wax remains dissolved, and the dissolved rice bran wax is discharged out of the system by solid-liquid separation in the subsequent step. As a result, the coating on the starch particles becomes insufficient, and sufficient water repellency cannot be obtained. Moreover, when cooling to less than 20° C., the time required for cooling becomes long, resulting in poor economy.
- a drying step of heating under normal pressure or reduced pressure may be provided in order to evaporate the solvent remaining in the cake-like substance. Furthermore, the dried solid matter is pulverized. As a result, a dry powder of coated particles having an average particle size of 0.5 to 20 ⁇ m is obtained.
- Cosmetics can be prepared by blending the above-described coated particles and various cosmetic ingredients. Such a cosmetic provides the same rolling feeling, long-lasting rolling feeling, and uniform spreadability as those of single-component inorganic particles (silica particles), and soft and moist sensations similar to those of plastic beads. Obtainable. That is, it is possible to satisfy the typical feel properties required for feel improvers for cosmetics.
- Examples of specific cosmetics are listed in Table 1 by category. Such cosmetics can be produced by conventionally known general methods. Cosmetics are used in various forms such as powder, cake, pencil, stick, cream, gel, mousse and liquid.
- Table 2 shows typical classifications and ingredients for various cosmetic ingredients. Furthermore, standards for quasi-drug raw materials 2006 (published by Yakuji Nippo Co., Ltd., June 16, 2006), International Cosmetic Ingredient Dictionary and Handbook (published by The Cosmetic, Toiletry, and Fragrance Association, Eleventh Edition 2006), etc. You may mix the cosmetic ingredients listed in.
- a starch dispersion is prepared. 250 g of Motil B (registered trademark) manufactured by Joetsu Starch Co., Ltd. was used as starch grains and added to 4750 g of pure water. The resulting suspension was heated and stirred (120° C., 16 hours). As a result, a starch dispersion (solid concentration: 5% by weight) was obtained. 200 g of this dispersion was added to a mixed solution of 3346 g of heptane (manufactured by Kanto Chemical Co., Ltd.) as a non-aqueous solvent and 25 g of surfactant (AO-10V, manufactured by Kao Corporation).
- Motil B registered trademark
- AO-10V surfactant
- This mixed solution was stirred at 10000 rpm for 10 minutes using an emulsifying disperser (TK Robomix manufactured by Primix). This resulted in an emulsified liquid containing emulsified droplets.
- This emulsified liquid was allowed to stand in a freezer at -25°C for 72 hours to freeze the water in the emulsified droplets. After that, the temperature was raised to normal temperature and thawed. This was filtered with quantitative filter paper (No. 2, manufactured by Advantech Toyo Co., Ltd.) using a Buchner funnel (3.2 L, manufactured by Sekiya Rika Glass Instruments Co., Ltd.). Thereafter, washing with 2500 g of heptane was repeated three times to remove the surfactant. The cake thus obtained was dried at 60° C. for 12 hours. This dry powder was sieved through a 250 mesh sieve (JIS test standard sieve) to obtain starch particles.

At this time, samples are prepared so that the ratio of rice bran wax is 0.5% by weight, 5% by weight, 10% by weight, and 20% by weight. 20 mg of each sample powder is molded into a 20 ⁇ disk. This was placed in an IR cell connected to a vacuum line, and vacuum exhaust treatment was performed at 70° C. for 1 hour to remove adsorbed moisture. After the evacuation process, the temperature is lowered to 25° C., and the IR spectrum of the sample disk is measured with an infrared absorption spectrometer (FT/IR-4600 manufactured by JASCO Corporation). Using the absorption peak intensity around 1700 cm ⁇ 1 obtained for each sample, a calibration curve of rice bran wax content and peak intensity is obtained.
- FT/IR-4600 infrared absorption spectrometer
- amylopectin Content of amylopectin Using an amylose/amylopectin analysis kit (manufactured by Nippon Biocon Co., Ltd.), the total starch content and amylose content were measured according to the procedure specified by the kit. The amylopectin content (% by weight) was determined by " ⁇ 1-(amylose amount/total starch amount) ⁇ 100".

Then, an emulsified liquid was prepared under the same emulsifying conditions as in Example 1. This emulsion was heated at 60° C. for 16 hours to dehydrate the emulsified droplets.
- this emulsion was stored at 2° C. for 16 hours. Furthermore, it was filtered with quantitative filter paper (No. 2, manufactured by Advantech Toyo Co., Ltd.) using a Buchner funnel (3.2 L, manufactured by Sekiya Rika Glass Instruments Co., Ltd.).

Abstract
Description
次に、被覆粒子の製造方法について説明する。ここでは、澱粉粒子を米ぬか蝋で表面処理した被覆粒子について詳述する。
まず、澱粉粒子の分散液を用意する。澱粉粒子の固形分濃度を1~20重量%の範囲に調整する。分散液の固形分濃度が20重量%を超えると澱粉粒子が凝集しやすくなる。そのため、後工程で米ぬか蝋の被覆状態が均一にならないおそれがある。その場合、所望の撥水性が得られない。1重量%未満では被覆粒子の収量が少なく経済性が悪い。なお、分散液の溶媒には、加熱によって米ぬか蝋が溶解するものを用いる。溶媒として有機溶媒が好ましい。特に、アルコール系溶媒が好ましく、IPA(イソプロピルアルコール)が適している。
この分散液に米ぬか蝋を添加し、加熱して米ぬか蝋を溶媒に溶解させる。米ぬか蝋の融点である78℃以上で加熱する。90℃未満が好ましいが、使用する溶媒に応じて適宜決めればよい。温度が低いと、米ぬか蝋が溶解しない、又は溶解が不充分になり、被覆状態が均一にならないおそれがある。90℃以上では、加温に時間がかかり経済性が悪い。
次に、従来公知の濾過、遠心分離等の方法を用いて、被覆粒子の分散液から固形分を分離する。これにより、被覆粒子のケーキ状物質が得られる。
上述の被覆粒子と各種化粧料成分を配合して化粧料を調製することができる。このような化粧料によれば、単一成分の無機粒子(シリカ粒子)と同様の転がり感、転がり感の持続性、および均一な延び広がり性、プラスチックビーズと同様のソフト感としっとり感を同時に得ることができる。すなわち、化粧料の感触改良材に求められる代表的な感触特性を満たすことができる。
はじめに、澱粉の分散液を準備する。澱粉穀粒として上越スターチ社のモチールB(登録商標)250gを用いて、純水4750gに加えた。得られた懸濁液を加熱攪拌(120℃、16時間)した。これにより、澱粉の分散液(固形分濃度5重量%)が得られた。この分散液200gを、非水系溶媒であるヘプタン(関東化学社製)3346gと界面活性剤(花王社製AO-10V)25gの混合溶液に加えた。この混合溶液を、乳化分散機(プライミクス社製T.K.ロボミックス)を用いて10000rpmで10分間撹拌した。これにより乳化され、乳化液滴を含む乳化液が得られた。この乳化液を、-25℃の冷凍庫中に72時間静置し、乳化液滴中の水を凍結させた。その後、常温まで昇温し、解凍した。これを、ブフナー漏斗(関谷理化硝子器械社製3.2L)を用いて定量濾紙(アドバンテック東洋社製No.2)で濾過した。その後、ヘプタン2500gを用いた洗浄を3回繰り返し、界面活性剤を除去した。このようにして得られたケーキ状物質を、60℃で12時間乾燥した。この乾燥粉体を250mesh篩(JIS試験用規格篩)でふるいにかけ、澱粉粒子を得た。
レーザー回折法を用いて、被覆粒子の粒度分布を測定した。この粒度分布からメジアン値を求め、平均粒子径d1とした。また、粒度分布で検出される最も大きい粒子径を最大粒子径d2とした。さらに、粒度分布(母集団)から標準偏差σと母平均μを求め、粒子変動係数(CV=σ/μ)を得た。表4では百分率で表している。また、最大粒子径d2を平均粒子径d1で除して最大粒子径と平均粒子径の比(d2/d1)を求めた。ここでは、粒度分布を堀場製作所製のLA-950v2を用いて測定した。
米ぬか蝋の主成分である高級アルコールエステルに含まれるカルボニル基に帰属する吸収ピークは1700cm-1付近にある。そこで、赤外吸光分光計を用いて測定したIRスペクトルの1700cm-1付近の値に基づいて、米ぬか蝋の含有量を特定した。
アミロース/アミロペクチン分析キット(日本バイオコン社製)を用いて、同キットが規定する手順に従い、総澱粉量、アミロース量を測定した。アミロペクチンの含有量(重量%)は、「{1-(アミロース量/総澱粉量)}×100」によりを求めた。
SDS-ポリアクリルアミドゲル電気泳動法を用いて、グロブリン残留量を測定した。まず、ドデシル硫酸ナトリウム(富士フィルム和光純薬社製)2g、尿素(富士フィルム和光純薬社製)24g、グリセリン10g、トリス(ヒドロキシメチル)アミノメタン(東京化成工業社製)0.76gを蒸留水で溶解した。この溶液を、1N塩酸水溶液を用いてpH6.8に調整した。さらに、2-メルカプトエタノール(富士フィルム和光純薬社製)2.5gを加えて100mLとし、これをタンパク質抽出液とした。実施例で得られた被覆粒子の粉体1gを、タンパク質抽出液0.7mLに加えて攪拌し、24時間静置した。その後、遠心分離にて上澄み液を分離した。この上澄み液0.01mLを、PGMEゲル(フナコシ社製)にチャージし、電気泳動を行った。その後、このゲルをCBB染色試薬(バイオダイナミクス研究所社製)し浸漬して染色した。染色されたゲルを画像解析(富士フィルム社製ルミノイメージアナライザーLAS-100plus、富士フィルム社製ImageGaugeによる自動定量)し、グロブリン残留量を算出した。
透過型電子顕微鏡(日立製作所製、H-8000)により、2000倍から25万倍の倍率で撮影し、写真投影図を得る。この写真投影図から、任意の50個の粒子を選び、それぞれの最大径DLと、これに直交する短径DSを測定し、比(DS/DL)を求めた。それらの平均値を真球度とした。
被覆粒子の粉体0.5gを水30mlに投入し、1時間静置後、目視で観察した。試料である粉体が水面に存在し、水中に沈んでいなければ“○”、水中に沈んだ場合は“×”と判定した。
澱粉粒子のIPA分散液(固形分濃度10重量%)90gに添加する米ぬか蝋の量を0.72gに変更した以外は、実施例1と同様にして被覆粒子の粉体を得た。
実施例1と同様に、澱粉の分散液(固形分濃度5重量%)を調製した。この分散液40gを純水160gで希釈し、固形分濃度を1重量%とした。この希釈分散液200gを、ヘプタン(関東化学社製)3346gと界面活性剤(花王社製AO-10V)25gの混合溶液に加えた。次いで、実施例1と同じ乳化条件で乳化液を調製した。この乳化液を60℃で16時間加熱し、乳化液滴を脱水した。脱水後、この乳化液を2℃で16時間冷却保管した。さらに、ブフナー漏斗(関谷理化硝子器械社製3.2L)を用いて定量濾紙(アドバンテック東洋社製No.2)で濾過した。これ以降は実施例1と同様にして被覆粒子の粉体を得た。
実施例1と同様に澱粉の分散液(固形分濃度5重量%)を調製し、この分散液200gを、ヘプタン3346gと界面活性剤(AO-10V)25gの混合液中に加えた。これ以降は実施例3と同様に被覆粒子を調製した。ただし、乳化工程における乳化分散機の回転速度を800rpmに、脱水工程における乳化液の加熱時間を24時間に変更した。
本実施例では、上越スターチ社のモチールB125gと上越スターチ社のファインスノウ(粳米由来アミロペクチン80%)125gを混合して澱粉穀粒とした。これ以外は実施例1と同様にして被覆粒子の粉体を得た。
本実施例では、アルカリ浸漬処理と酵素処理により澱粉穀粒のグロブリン量を低減させた。この澱粉穀粒を用いて澱粉粒子を調製した。まず、モチールB1kgを純水4kgに加え、得られた懸濁液に、5重量%の水酸化ナトリウム水溶液を加えて、pHを9.0に調整した(アルカリ浸漬処理)。さらに、酵素(ヤクルト薬品工業社製アロアーゼ AP-10)10gを加え、室温で24時間攪拌した(酵素処理)。次いで、この溶液を、ブフナー漏斗(関谷理化硝子器械社製3.2L)を用いて定量濾紙(アドバンテック東洋社製No.2)で濾過した。さらに、純水で洗浄して残留酵素と分解されたタンパク質を除去した。これにより得られたケーキ状物質を、60℃で12時間乾燥した。この乾燥粉体を250mesh篩(JIS試験用規格篩)でふるいにかけた。これにより、グロブリンが低減された澱粉の粉体が得られた。この粉体250gを純水4750gに懸濁した。この懸濁液を、加熱攪拌(120℃、16時間)して、澱粉の分散液(固形分濃度5重量%)を調製した。これ以降は実施例1と同様にして被覆粒子の粉体を得た。本実施例で得られた被覆粒子のグロブリン残留量は0.02重量%であった。
澱粉粒子のIPA分散液(固形分濃度10重量%)90gに添加する米ぬか蝋の量を0.05gに変更した以外は実施例1と同様にして被覆粒子の粉体を得た。
澱粉粒子のIPA分散液(固形分濃度10重量%)に米ぬか蝋を添加しなかった。これ以外は、実施例1と同様に被覆粒子の粉体を調製した。
澱粉粒子のIPA分散液90gに添加する米ぬか蝋の量を1.35gに変更した以外は実施例1と同様にして被覆粒子の粉体を得た。
本比較例では、固形分濃度20重量%の澱粉の分散液を調製した。すなわち、モチールB1000gを純水4000gに懸濁して、固形分濃度20重量%の分散液を調製した。この分散液200gを、ヘプタン3346gと界面活性剤(AO-10V)25gの混合液中に加えた。これ以降は実施例4と同様に澱粉粒子を調製した。
次に、各実施例と比較例で得られた粉体の感触特性を評価した。各粉体について、20名の専門パネラーによる官能テストを行い、さらさら感、しっとり感、転がり感、均一な延び広がり性、肌への付着性、転がり感の持続性、およびソフト感の7つの評価項目に関して聞き取り調査を行った。評価点基準(a)に基づく各人の評価点を合計し、評価基準(b)に基づき感触特性を評価した。結果を表5に示す。その結果、各実施例の粉体は、化粧料の感触改良材として極めて優れているが、比較例の粉体は、感触改良材として適していないことが分かった。
評価点基準(a)
5点:非常に優れている。
4点:優れている。
3点:普通。
2点:劣る。
1点:非常に劣る。
評価基準(b)
