Description

  The present invention relates to a composition that can be used in cosmetics and a cosmetic containing the same.

  Conventionally, various surfactants have been added to cosmetics for the purpose of increasing the viscosity of the cosmetics, adjusting the viscosity, improving the feeling of application, and imparting detergency. As such surfactants, amino acid surfactants and fatty acid soaps are known. Amino acid surfactants and fatty acid soaps have the advantage of providing a refreshing feel with low irritation.

  However, amino acid-based surfactants and fatty acid soaps, when used in cosmetics, have low viscosity, poor foaming properties (for example, poor foaming, poor foam stability, and rough foam).

BEST MODE FOR CARRYING OUT THE INVENTION

  The composition according to the present invention comprises (A) a crosslinked product in which hydroxyalkyl-modified starch having 2 to 5 carbon atoms is crosslinked, a hydroxyalkyl-modified starch having 2 to 5 carbon atoms, and an acyl-modified starch having 2 to 18 carbon atoms. At least one selected from a crosslinked product obtained by crosslinking, a crosslinked product obtained by crosslinking acyl-modified starch having 2 to 18 carbon atoms (hereinafter also referred to as “(A) starch crosslinked product”), and (B) an amino acid surfactant. And at least one selected from fatty acid soaps.

The composition according to the present invention includes not only the form of an aqueous composition but also a form not containing a medium such as an aqueous medium, but the composition according to the present invention is particularly limited by the form. It is not something. The composition according to the present invention is preferably in the form of an aqueous composition containing an aqueous medium.
In the present specification, the composition “aqueous” means that a starch cross-linked product contained in the composition, a surfactant, and other components that can be contained in the composition are present in the aqueous medium. It includes a state where these resins are dissolved and / or dispersed in an aqueous medium.
Throughout this specification, parts by weight and% by weight are based on parts excluding a medium such as an aqueous medium unless otherwise specified.

  In the present specification, the “aqueous medium” refers to general water such as distilled water and ion-exchanged water, for example, but when the composition of the present invention is in the form of an aqueous composition, it adversely affects its properties. In the range which does not have a bad influence on the use as cosmetics mentioned later, you may contain the organic solvent, monomer, oligomer, etc. which are water-soluble or dispersible in water.

  The composition according to the present invention can be provided in any form, such as a solution, emulsion, suspension, gel or foam, and further provided as a form of a medium-free composition (eg, a dry powder composition). can do. When the composition according to the present invention is used in the form of an aqueous composition, it is preferably used after it is in the form of an aqueous composition in an aqueous medium.

In the present invention, “(A) a crosslinked product in which hydroxyalkyl-modified starch having 2 to 5 carbon atoms is crosslinked, a hydroxyalkyl-modified starch having 2 to 5 carbon atoms and an acyl-modified starch having 2 to 18 carbon atoms is crosslinked. "Crosslinked product, at least one selected from crosslinked products in which acyl-modified starch having 2 to 18 carbon atoms are crosslinked" (or (A) starch crosslinked product) is a specific modified starch, that is, 2 to 5 carbon atoms. These two types of modified starches, namely hydroxyalkyl-modified starches and acyl-modified starches having 2 to 18 carbon atoms, are crosslinked between the same species or between different species (refer to JP 2000-514435 A).
Furthermore, these cross-linked products can be used alone or in combination.

  “Hydroxyalkyl-modified starch having 2 to 5 carbon atoms” is a starch in which a hydroxyl group is bonded to a starch skeleton through an alkyl group having C2 to C5 carbon atoms, and is suitable for the hydrophilicity-new oiliness of starch. A good balance. The position of the hydroxyl group in the alkyl group is not critical and can be any position. The degree of substitution by hydroxyalkylation is preferably 0.08 to 0.3. The degree of substitution is the average number of hydroxyl groups of starch molecules per unit of anhydroglycol. Hydroxyalkylation of natural starch is accomplished by reacting with an alkene oxide having the appropriate number of carbon atoms in natural starch. Hydroxyethylated starch and / or hydroxypropylated starch obtained by reacting starch with ethylene oxide or propylene oxide is particularly preferred. In addition, you may have several hydroxyl groups per alkyl group.

The “C2-C18 acyl-modified starch” is a starch acylated with a C2-C18 acyl group, and a suitable balance between hydrophilicity and lipophilicity of the starch is obtained. The acylation is usually performed by a reaction with an acid anhydride represented by the general formula (R—CO) ₂ O. Here, R represents an alkyl group such as a methyl group or an ethyl group.

  Cross-linking of these modified starches is achieved by a suitable cross-linking agent, i.e. a bifunctional compound. As a preferred crosslinking method, for example, phosphorylation can be exemplified. In this case, the starch is reacted with phosphoryl chloride, phosphorus pentoxide and / or sodium trimetaphosphate. The two starches are cross-linked by anionic P—O groups. The anionic character of the cross-linking site helps the emulsion stabilizing action of the modified starch described above.

Furthermore, as a preferable crosslinking method, a method using a C4 to C18 alkane dicarboxylic acid or alkene dicarboxylic acid can be exemplified. It is preferable to use C4-C8 alkanedicarboxylic acid, particularly adipic acid. C4-C18 alkane dicarboxylic acids or alkene dicarboxylic acids bind two starches via an ester bond. The starch may be linear or branched. Such a crosslinked product crosslinked with a dicarboxylic acid can be obtained, for example, by reacting starch with a mixed anhydride of dicarboxylic acid and acetic acid. In the case of dry starch, generally less than 0.1% by weight, usually 0.6% by weight of a crosslinking agent is used.
As the starch cross-linked product, hydroxypropyl distarch phosphate and acetylated dister thiadipate are particularly preferred.

  The starting starch used to obtain the specific starch described above may be any vegetable starch. Examples of such starting starch include corn, potato, wheat, rice, tapioca, sweet potato and sago. These starting starches preferably have an amylopectin content of at least 70% by weight, more preferably at least 85% by weight and particularly preferably at least 90% by weight.

  The above-mentioned specific starch cross-linked product (A) is preferably gelatinized, and is preferably completely gelatinized. For gelatinization, the starting starch may be gelatinized in advance, or the cross-linked product may be gelatinized, and (A) the specific starch cross-linked product used as a result is preferably gelatinized.

Examples of methods commonly used for producing such starch include cylindrical drying and extrusion spray drying.
Cylindrical drying includes simultaneous cooking and drying of a highly viscous semi-solid starch paste on a heated drum. The dried film is peeled off from the drum using a metal blade and then crushed. This step can be carried out until the solid content is very high.

  Extrusion drying can be used to simultaneously cook and dry starch (see US Pat. No. 3,137,592). This method utilizes the physical treatment of the starch / water mixture at high temperature and pressure, whereby the starch is gelatinized and the starch coming out of the nozzle is suddenly exposed to water. Expands with evaporation.

  By using the gelatinized (A) starch cross-linked product, the composition according to the present invention is produced at a temperature lower than the ambient temperature and lower than the temperature used to produce a known starch-containing composition. can do.

  The gelatinized (A) starch cross-linked product is preferably produced by spray drying. Using other drying methods, such as cylindrical drying, tends to form a less soluble starch crust, which can result in undissolved particles in the composition of the present invention.

  (A) Most of the crosslinked starch is preferably intact starch granules. Dispersions of gelatinized starch derivatives that are mostly intact granule structures are more uniform than starch dispersions that do not have a granule structure, such as those obtained by drying starch solutions. Has a smooth texture. In the case of gelatinized starch having an intact granule structure, the original internal structure called hydrogen bonding is destroyed, but the appearance or external shape is maintained.

  Reference can be made to US Pat. No. 4,280,851 for a particularly suitable method for producing a cross-linked product of gelatinized starch by spray drying. A suitable apparatus for carrying out this method can be referred to US Pat. No. 4,600,472. In this method, granular starch or granular starch cross-linked product is made into a mist and cooked or gelatinized. The starch to be cooked or the starch cross-linked product is atomized between the nozzle and the nozzle device so as to be a relatively finely divided spray. Further, a heating medium is injected into the spray material through the opening of the nozzle device, and the starch is heated to a temperature necessary for gelatinization. A sealed chamber surrounds the spray and heating medium inlet and is formed with a priming port positioned so that the heated starch spray can leave the chamber. The apparatus is such that the starch gelatinization time can be determined by the elapsed time while the starch spray material passes through the chamber, that is, from the spray port to the ventilation port. The resulting spray-dried starch, cross-linked starch, contains jagged, spherical, uniformly gelatinized starch particles, the majority of the granules being intact and intact, It expands after being summed. Nozzles that can be used to produce such starch are described in US Pat. No. 4,610,760.

  The methods described in US Pat. No. 5,149,799 can also be used to produce the preferred gelatinized starch or gelatinized starch cross-linked product. In this method, starch is uniformly atomized and cooked in a single atomization step in the presence of an aqueous medium. The atomization stage is carried out in an apparatus equipped with an internal mix two-fluid spray drying nozzle, which is also connected to a cooked and atomized starch drying apparatus.

  The spray-dried preferred gelatinized starch, starch cross-linked product can also be produced by a continuous, coupled jet-cooking and spray-drying process. The starch suspension is gelatinized at 138 ° C to 160 ° C with direct steam injection in a jet cooker. The starch suspension and steam stream are mixed in a cooking or boiling chamber. The latter exhaust port is connected to a pneumatic spray nozzle or a high-pressure nozzle installed in a conventional spray dryer. The jet-cooked starch is guided into the spray nozzle under high temperature and pressure and is atomized by cold air, hot air or preferably steam. The jet cooked hot starch solution is treated in the same way as conventional spray-dried starch after being atomized. The drying process is performed reasonably quickly to prevent starch particles from aging during cooling and drying of the droplets. Spray dried starch is amorphous (ie substantially non-crystalline) and is readily soluble or colloidally dispersible in water.

  The (A) starch cross-linked product can also be used with other starches such as natural starch and modified starch.
