Abstract
Description
Technical Field
[0001] This invention relates to organopolysiloxane-modified cyclodextrin compounds and cosmetics containing them. Background Technology
[0002] Cyclodextrins have a donut-like structure, with a lipophilic inner surface and a hydrophilic outer surface, exhibiting inclusion properties that allow various active substances to be contained within the cavities. Therefore, they are widely used in pharmaceuticals, food, cosmetics, textiles, coatings, and other products because they can solubilize poorly soluble substances and improve product stability. While the addition of cyclodextrins is common, polymers containing cyclodextrin groups have also been reported. For example, cyclodextrin condensation polymers obtained by reacting cyclodextrins with diisocyanate compounds are used as selective fixatives for halogenated aromatic compounds contained in organic media (Patent Document 1). Furthermore, derivatives of cyclodextrins bonded via amide groups can improve the water solubility of poorly soluble compounds, and their applications in pharmaceuticals and cosmetics have been reported (Patent Documents 2, 3).
[0003] Acrylic hydrogels with cyclodextrins in their side chains have the ability to introduce drugs, active substances, or protective agents, and are used in contact lenses and cosmetics (Patent Document 4). Additionally, various guest molecules are encapsulated using cyclodextrin conjugates containing polyoxyethylene as a linker (Patent Document 5). However, these are all aimed at encapsulating various substances.

[0060] The sugar unit represented by formula (1) is preferably a cyclodextrin structure comprising sugar units from cyclodextrin compounds selected from α-cyclodextrin, β-cyclodextrin, and γ-cyclodextrin, as well as derivatives of these cyclodextrins having hydroxyethyl or hydroxypropyl groups.
[0061] In formula (1), R is independently selected from hydrogen atoms, triorganosilyl-modified amide groups represented by formula (2), and linking groups with divalent urethane bonds represented by formula (3), and the number of moles of hydrogen atoms N in 1 mole of the organopolysiloxane-modified cyclodextrin compound. H The number of moles N of the groups represented by the above formula (2) S The number of moles N of the group represented by the above formula (3) L The ratio is N H :N S :N L =0.5~2.5:0.3~2.0:0.1~0.5, to become NH +N S +N L Choose the appropriate method for the range = 3.0.

[0072] [Chemistry 11]
[0073]
[0074] (where R is in the formula) 2 (a) is independently selected from alkyl groups having 1 to 8 carbon atoms, fluorosubstituted alkyl groups having 1 to 8 carbon atoms, aryl groups having 6 to 12 carbon atoms, and aralkyl groups having 7 to 12 carbon atoms; b is independently 2 to 4; c is independently an integer from 2 to 12; d is an integer from 0 to 200; and e is independently 0 to 40.

Specific examples, preferred examples, etc., can be listed as groups that are the same as the groups exemplified in X above. The p in formula (4) is a number from 1 to 5, preferably 1 to 3. By making p 5 or less, the molecular weight of the organopolysiloxane modified cyclodextrin compound of the present invention is suppressed, and when it is to be formulated as a cosmetic, its solubility with oils becomes good, and the formulation stability is further improved.
[0077] Sx is a divalent group represented by formula (5) that has a siloxane bond in the main chain. In formula (5), R 2 The group is independently selected from alkyl groups having 1 to 8 carbon atoms, fluorosubstituted alkyl groups having 1 to 8 carbon atoms, aryl groups having 6 to 12 carbon atoms, and aralkyl groups having 7 to 12 carbon atoms.

[0084] It should be noted that, as can be seen from the above ratios, it is not necessary for all hydroxyl groups to be replaced by the substituents represented by formulas (2) and (3) above; the presence of hydroxyl groups in the sugar units is a characteristic feature. Since the solubility, degree of crosslinking, and molecular weight change in each oil depending on their ratios, they can be combined according to the oil used. Furthermore, these organopolysiloxane-modified cyclodextrin compounds can also be directly incorporated into cosmetics, but they are generally in solid form, preferably in a state dissolved in the oil or gelled in the oil. As an oil in this case, the same oil as that used in the cosmetics of the present invention described below can be used.
