  • Patent number: 10308898
    Abstract: The present invention discloses a method of imparting water repellency and optionally stain release to fibrous substrates by contacting a fibrous substrate with a non-fluorinated laundry treatment composition inside a laundry machine. The laundry treatment composition contains a hydrophobic organic urethane compound having a urethane linkage and the residue of a substituted cyclic or acyclic sugar alcohol. Laundry additive compositions containing a first laundry treatment composition, having a hydrophobic organic urethane compound, and a second laundry treatment composition are also included.
