Abstract: Provided is a composition containing, as an alkane polyol, a C4-18 1,2-alkane polyol in which the degradation over time of the C4-18 1,2-alkane polyol, which has inferior chemical stability and degrades easily, is suppressed, the composition being suitable for use in a cosmetic, an inkjet ink, a fiber or a coating material such as a paint. A composition containing 1,2-alkane polyol that can be used in a cosmetic, an inkjet ink, a raw material for fibers or a coating material, the alkane polyol being a C4-18 1,2-alkane polyol, and the composition containing a radical scavenger.

Abstract: A biocompatible material having excellent biocompatibility such as small interaction with a component of a living body such as a protein or blood cell. A biocompatible material comprising a polymer obtained by polymerizing a monomer composition comprising an amino acid-type betaine monomer represented by the formula (I): wherein R1 is a hydrogen atom or a methyl group; R2 is an alkylene group having 1 to 6 carbon atoms; each of R3 and R4 is independently an alkyl group having 1 to 4 carbon atoms; R5 is an alkylene group having 1 to 4 carbon atoms; and Z is an oxygen atom or an —NH group; and a polymerizable monomer represented by the formula (II): wherein R1 is as defined above; and R6 is a monovalent organic group, in a weight ratio, i.e. amino acid-type betaine monomer/polymerizable monomer, of from 1/99 to 100/1. The biocompatible material can be suitably used, for example, in food, a food additive, a medicament, a quasi-drug, a medical device, cosmetics, a toiletry article, or the like.
