Abstract

The present invention is an aqueous composition comprising at least one hydrophobic compound having at least one linkage of Formula I: - NHC(O)-X- (I) wherein X is the residue of a cyclic or acyclic sugar alcohol which is substituted with at least one -R1; -C(O)R1; (CH2CH2O)n(CH(CH3)CH2O)mR2; (CH2CH2O)n(CH(CH3)CH2O)mC(O)R1; or mixtures thereof; where the cyclic or acyclic sugar alcohol is selected from a saccharide, reduced sugar, aminosaccharide, aldonic acid, or aldonic acid lactone; wherein each n is independently 0 to 20; each m is independently 0 to 20; m+n is greater than 0; each R1 is independently a linear or branched alkyl group having 5 to 29 carbons optionally comprising at least 1 unsaturated bond; each R2 is independently -H, a linear or branched alkyl group having 6 to 30 carbons optionally comprising at least 1 unsaturated bond, or mixtures thereof.

Description

technical field

[0001] The present invention relates to aqueous compositions comprising hydrophobic organic urethane compounds derived from sugar alcohols useful for imparting durable water resistance and optionally stain release properties to textiles. Background technique

[0002] Various compositions are known for use as treatments to provide water repellency and optionally stain release to textile substrates. Many of these treatments are fluorinated polymers and copolymers, or non-fluorinated polymers and copolymers. Non-fluorinated compounds are mainly polyacrylate-based or urethane-based copolymers.

[0003] Fluorinated copolymers provide good water and oil repellency. Various attempts have been made to produce non-fluorinated water repellents. Non-fluorinated copolymers are known to provide water resistance and optionally stain release to textiles, but less effectively than their fluorinated counterparts.
