Description

[Technical field]

[0001] The present invention relates to an organopolysiloxane-modified cyclodextrin compound and a cosmetic composition containing the same. [Background technology]

[0002] Cyclodextrin has a doughnut-shaped structure, with the inside being lipophilic and the outside being hydrophilic, and has the ability to incorporate various active substances into the cavity. Therefore, it can solubilize poorly soluble substances and improve the stability in the product, and is therefore widely used in products such as medicines, foods, cosmetics, fibers, and paints. Cyclodextrin is often added and used, but polymers containing cyclodextrin groups have also been reported. For example, cyclodextrin condensation polymers obtained by reacting cyclodextrins with diisocyanate compounds are used as selective fixing agents for halogenated aromatic compounds contained in organic media (Patent Document 1). In addition, derivatives in which cyclodextrin is bonded via an amide group can improve the water solubility of poorly water-soluble compounds, and their application to medicines and cosmetics has been reported (Patent Documents 2 and 3).

[0003] Acrylic hydrogels with cyclodextrin in the side chain have the ability to incorporate drugs, active substances, or protective agents, and are used in contact lenses and cosmetics (Patent Document 4). In addition, cyclodextrin conjugates containing polyoxyethylene groups as linkers are used to encapsulate various guest molecules (Patent Document 5). However, all of these are intended to encapsulate various substances. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The present invention will be described in detail below. [Component (A)] The organopolysiloxane-modified cyclodextrin compound of the present invention is represented by the following formula (1): [ka] [In the formula, R independently represents a hydrogen atom, [ka] (In the formula, R 1 are independently a group selected from an alkyl group having 1 to 8 carbon atoms, a fluorine-substituted alkyl group having 1 to 8 carbon atoms, an aryl group having 6 to 12 carbon atoms, and an aralkyl group having 7 to 12 carbon atoms, n is an integer of 1 to 10, and a is an integer of 0 to 3. or a group represented by the following formula (3): [ka] (In the formula, X is a divalent organic group, and * is a bond that bonds to a hydroxyl group of another sugar unit.) is a group represented by the following formula: The organopolysiloxane-modified cyclodextrin compound is composed of sugar units represented by the following formula: H , the number of moles N of the group represented by the above formula (2) S, the number of moles N of the group represented by the above formula (3) L The ratio of N H :N S :N L = 0.5~2.5:0.3~2.0:0.1~0.5, and N H +N S +N L = 3.0.

[0010] The sugar unit represented by formula (1) is preferably a cyclodextrin structure consisting of sugar units derived from a cyclodextrin compound selected from α-cyclodextrin, β-cyclodextrin, and γ-cyclodextrin, as well as derivatives of these cyclodextrins having a hydroxyethyl group or a hydroxypropyl group.

[0011] R in formula (1) is independently a group selected from a hydrogen atom, a triorganosilyl-modified amide group represented by formula (2), and a linking group having a divalent urethane bond represented by formula (3), and N is the number of moles of hydrogen atoms in 1 mole of the organopolysiloxane-modified cyclodextrin compound. H , the number of moles N of the group represented by the above formula (2) S , the number of moles N of the group represented by the above formula (3) L The ratio of N H :N S :N L = 0.5~2.5:0.3~2.0:0.1~0.5, and N H +N S +N L = 3.0.

[0012] In the triorganosilyl-modified amide group represented by formula (2), R 1are independently selected from an alkyl group having 1 to 8 carbon atoms, a fluorine-substituted alkyl group having 1 to 8 carbon atoms, an aryl group having 6 to 12 carbon atoms, and an aralkyl group having 7 to 12 carbon atoms. Examples of the alkyl group include linear alkyl groups such as methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, and octyl groups, and cycloalkyl groups such as cyclopentyl and cyclohexyl groups. Examples of the aryl group include aryl groups such as phenyl and tolyl groups, and examples of the aralkyl group include benzyl and phenethyl groups. Examples of the fluorine-substituted alkyl group include trifluoropropyl and heptadecafluorodecyl groups. Among them, alkyl groups having 1 to 8 carbon atoms and phenyl groups are preferred, and methyl groups are more preferred.

[0013] n is an integer of 1 to 10, preferably 2 to 6, and more preferably 3. a is an integer of 0 to 3, and preferably 3. If it is within this range, the compatibility of the obtained organopolysiloxane-modified cyclodextrin compound with oils such as silicone oils is further improved. Furthermore, cosmetics using such organopolysiloxane-modified cyclodextrin compounds have good spreadability, are not sticky, and have an excellent feel when used.

[0014] In the linking group having a divalent urethane bond represented by formula (3), X is a divalent organic group, and * is a bond that bonds to the hydroxyl group of another sugar unit. By using urethane bonds to link cyclodextrins together, the molecules have self-association properties due to intermolecular interactions, and can exhibit the thickening properties of oils such as silicone oil. In addition, by adjusting the amount of urethane bonds, the product does not feel sticky when incorporated into cosmetics, has excellent adhesion to the skin, and can also improve the durability of the cosmetics.

[0015] Examples of the divalent organic group X include a divalent aliphatic hydrocarbon group having 1 to 10 carbon atoms, a divalent aromatic hydrocarbon group having 6 to 20 carbon atoms, or a divalent group having a siloxane bond in the main chain represented by formula (4). Among these, the divalent group represented by formula (4) is preferred because it has a siloxane bond at the linking site between cyclodextrins, which can further improve compatibility with oils such as silicone oils and can expand the types of oils that can be blended and stabilized.

[0016] Examples of divalent aliphatic hydrocarbon groups having 1 to 10 carbon atoms include alkylene groups having 1 to 10 carbon atoms and cycloalkylene groups having 5 to 10 carbon atoms. Specific examples include methylene groups, ethylene groups, trimethylene groups, ethylidene groups, isopropylidene groups, tetramethylene groups, pentamethylene groups, hexamethylene groups, cyclohexylene groups, and divalent hydrocarbon groups having a cyclohexyl ring derived from isophorone diisocyanate.

[0017] Examples of divalent aromatic hydrocarbon groups having 6 to 20 carbon atoms include 1,3-phenylene group, 1,4-phenylene group, 2-methyl-1,3-phenylene group, 4-methyl-1,3-phenylene group, diphenylmethane-4,4'-diyl group, etc. Among these divalent hydrocarbon groups, a hexamethylene group and a divalent hydrocarbon group having a cyclohexyl ring derived from isophorone diisocyanate are preferred.

[0018] A divalent group having a siloxane bond in the main chain, represented by the following formula (4): [ka] [where, X 1 are independently a divalent aliphatic hydrocarbon group having 1 to 10 carbon atoms or a divalent aromatic hydrocarbon group having 6 to 20 carbon atoms, and Sx is represented by the following formula (5): [ka] (In the formula, R 2are independently a group selected from an alkyl group having 1 to 8 carbon atoms, a fluorine-substituted alkyl group having 1 to 8 carbon atoms, an aryl group having 6 to 12 carbon atoms, and an aralkyl group having 7 to 12 carbon atoms, b is independently 2 to 4, c is independently an integer of 2 to 12, d is independently an integer of 0 to 200, and e is independently 0 to 40. where p is a number from 1 to 5.]

[0019] In the divalent group having a siloxane bond in the main chain represented by formula (4), X 1 are each independently a divalent aliphatic hydrocarbon group having 1 to 10 carbon atoms or a divalent aromatic hydrocarbon group having 6 to 20 carbon atoms. Specific and preferred examples can be the same as those exemplified for X above. In formula (4), p is a number from 1 to 5, and preferably 1 to 3. By setting p to 5 or less, the molecular weight of the organopolysiloxane-modified cyclodextrin compound of the present invention is reduced, and when it is intended to be incorporated into a cosmetic composition, the solubility with oils is improved, and the compounding stability is further improved.

[0020] Sx is a divalent group having a siloxane bond in the main chain, represented by formula (5). In formula (5), R 2 are independently selected from an alkyl group having 1 to 8 carbon atoms, a fluorine-substituted alkyl group having 1 to 8 carbon atoms, an aryl group having 6 to 12 carbon atoms, and an aralkyl group having 7 to 12 carbon atoms. Specific examples and preferred examples are as described above for R 1 Examples of the substituents include the same as those exemplified in 1. b is independently 2 to 4, and preferably 2 or 3. c is independently an integer of 2 to 12, and preferably 2 or 3. d is an integer of 0 to 200, and preferably an integer of 0 to 100, and more preferably an integer of 1 to 80. e is independently 0 to 40, and preferably 0 to 20, and more preferably 1 to 15.

[0021] The number of moles of hydrogen atoms in 1 mole of organopolysiloxane-modified cyclodextrin compound is N H , the number of moles N of the group represented by the above formula (2) S , the number of moles N of the group represented by the above formula (3) LIn other words, the ratio (proportion) of the hydrogen atoms of three hydroxyl groups in the sugar units constituting the organopolysiloxane-modified cyclodextrin compound that are substituted with the triorganosilyl-modified amide group represented by the above formula (2) and the divalent organic group represented by the above formula (3) is as follows: N H :N S :N L =0.5~2.5:0.3~2.0:0.1~0.5 (N H +N S +N L = 3.0.) N H : Number of moles of hydrogen atoms N S : Number of moles of the above formula (2) N L : Number of moles of the above formula (3) N H :N S :N L The ratio is preferably 0.5-2.5:0.4-2.0:0.1-0.5, and more preferably 1.0-2.45:0.45-1.75:0.1-0.4.

[0022] As is clear from the above ratio, it is not necessary for all hydroxyl groups to be substituted with the substituents represented by the above formula (2) or (3), and the hydroxyl groups of the sugar units remain. These ratios affect the solubility in each oil, the degree of crosslinking, and the molecular weight, so they can be combined according to the oil used. In addition, this organopolysiloxane-modified cyclodextrin compound can be directly incorporated into the cosmetic, but since it is usually in a solid form, it is preferable to incorporate it into the cosmetic in a state where it is dissolved in an oil or gelled in an oil. In this case, the oil can be the same as the oil that can be incorporated into the cosmetic of the present invention described later.

The gelling (thickening) properties are shown in Table 1.

[0091] [Table 1]

[0092] All of Synthesis Examples 1 to 5 were dissolved at 100° C. and gelled at room temperature with no fluidity. On the other hand, Comparative Synthesis Example 1 was dissolved at 100° C. and did not gel at room temperature, whereas Comparative Synthesis Example 2 was not dissolved at 100° C. and was not dissolved at room temperature.

[0093] [Examples and Comparative Examples (Stability Evaluation)] Components (1), (3), (4) to (9) were mixed and uniformly dispersed, and then (2) was gradually added and mixed. To this, a solution of components (10), (11), and (12) was gently added and emulsified to obtain a water-in-oil emulsion with the composition shown in Table 2. The obtained water-in-oil emulsion was filled into a glass bottle, and the appearance after 7 days at 50°C was visually inspected, and the stability over time was evaluated based on the change in viscosity from the initial emulsion. The viscosity was measured at 25°C using a BM type viscometer (manufactured by Toki Sangyo Co., Ltd.) (rotor No. 3 or No. 4, 30 rpm, 1 minute). The blend amounts in the table are the blend amounts of the blended products shown (the same applies below).
