A novel saccharide siloxane copolymer has improved stability in the presence of water as compared to certain previously known saccharide siloxanes. The saccharide siloxane copolymer is useful in personal care compositions. 1. A saccharide siloxane copolymer of formula:{'br': None, 'sup': 2', '1', '2', '1', '1', '1', '2, 'sub': a', '(3-a)', 'm', '2', 'n', 'y', '(3-a)', 'a, 'RRSiO—[(SiRRO)—(SiRO)]—SiRR; where'}{'sup': 1', '1', '3, 'claim-text': 'Q comprises an epoxy, cycloalkylepoxy, primary or secondary amino, ethylenediamine, carboxy, halogen, vinyl, allyl, anhydride, or mercapto functionality;', 'each Rcan be the same or different and each Rcomprises hydrogen, an alkyl group, an organic group, or a group of formula R-Q;'}subscripts m and n are integers from 0 to 10,000 and may be the same or different;each subscript a is independently 0, 1, 2, or 3;subscript y is an integer such that the copolymer has a molecular weight less than 1 million;{'sup': 2', '1', '2', '2, 'sub': b', 'c, 'claim-text': [{'sup': '1', 'Gis a saccharide component comprising 5 to 12 carbon atoms,'}, 'a quantity (b+c) has a value ranging from 1 to 10, and', 'subscript b or subscript c can be 0,', {'sup': '2', 'Gis a saccharide component comprising 5 to 12 carbon atoms additionally substituted with organic or organosilicon radicals,'}, {'sup': 3', '8', '4', '3', '8', '4', '3', '4', '8, 'sub': 2', '2, 'claim-text': [{'sup': 3', '4', '5', '6', '7, 'sub': r', 's', 't, 'claim-text': where at least one of subscripts r, s and t is 1, and', {'sup': 5', '7', '9, 'sub': 'p', 'each Rand each Rare independently either an alkylene group of 1 to 12 carbon atoms or a group of formula (RO), where'}, 'subscript p is an integer with a value ranging from 1 to 50, and', {'sup': '9', 'each Ris a divalent organic group, and'}, {'sup': '90', 'each Rmay be the same or different,'}, {'sup': 6', '8', '8', '3, 'each Ris —N(R)—, where Ris selected from R, a group of formula Z—X, an unsaturated hydrocarbon group, or a ...
