Document Type and Number:
WIPO Patent Application WO/2022/259964
Kind Code:
A1
Abstract:
This organopolysiloxane-modified cyclodextrin compound is composed of a sugar unit represented by formula (1) [in the formula, R is a hydrogen atom, a group represented by formula (2) (in the formula, R1 is a group selected from among a C1-C8 alkyl group, a C1-C8 fluorine-substituted alkyl group, and a C6-C12 aryl group, n is an integer of 1-10, and a is an integer of 0-3), or a group represented by formula (3) (in the formula, X is a divalent organic group, and * is a bond that is bonded to a hydroxyl group of another sugar unit)], wherein the ratio among the number NH of moles of the hydrogen atom, the number NS of moles of the group represented by formula (2), and the number NL of moles of the group represented by formula (3) satisfies NH:NS:NL=0.5-2.5:0.3-2.0:0.1-0.5, and NH+NS+NL is 3.0.
