The present invention relates to a coating composition with 10 to 100% by weight of a non-fluorinated compound mixture, which comprises at least one compound b and at least one compound a, c, or d: a) alkali metal salt of poly(meth)acrylic acid, alkali metal salt of poly(meth)acrylic acid copolymer, ammonium compound or amine salt of poly(meth)acrylic acid, ammonium compound or amine salt of poly(meth)acrylic acid copolymer, or mixtures thereof; b) silicone polyether, alkali metal salt of silicone polyether carboxylate, ammonium compound or amine salt of silicone polyether carboxylate, or mixtures thereof; c) salt of hydrolyzed &#x3b1;-olefin/maleic anhydride copolymer, salt of esterified &#x3b1;-olefin/maleic anhydride copolymer, &#x3b1;-olefin/maleic anhydride copolymer amic acid resin or salt thereof, or mixtures thereof; or d) polycarboxylate calcium sequestrants or mixtures thereof. Such coatings exhibit improved soil and stain cleaning performance.

Non-fluorinated coating and finish agents

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.

Method of imparting water repellency with non-fluorinated laundry treatment compositions

The present invention is an aqueous composition comprising at least one hydrophobic compound having at least one linkage of Formula I:&#x2014;NHC(O)&#x2014;X&#x2014;&#x2003;&#x2003;(I)wherein X is the residue of a cyclic or acyclic sugar alcohol which is substituted with at least one &#x2014;R; &#x2014;C(O)R; &#x2014;(CHCHO)(CH(CH)CHO)R; &#x2014;(CHCHO)(CH(CH)CHO)C(O)R; 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 Ris independently a linear or branched alkyl group having 5 to 29 carbons optionally comprising at least 1 unsaturated bond; each Ris independently &#x2014;H, a linear or branched alkyl group having 6 to 30 carbons optionally comprising at least 1 unsaturated bond, or mixtures thereof.

Non-fluorinated urethane based coatings

A compound for imparting water repellency and optionally stain release to substrates wherein the compound is prepared by reacting (a) at least one isocyanate group-containing compound, (b) at least one isocyanate-reactive compound and (c) at least one fluorinated isocyanate-reactive compound.

Partially fluorinated urethane based coatings

The invention relates to isocyanate derived organosilanes and the use thereof. The isocyanate derived organosilanes can be reacted with inorganic substrates, such as oxide particles, to result in a surface modified inorganic substrate.

Isocyanate derived organosilanes

Polyurethanes derived from non-fluorinated or partially fluorinated polymers

The present invention is a method for imparting surface effects to a substrate using at least one hydrophobic compound with at least one linkage of Formula I:&#x2014;NHC(O)&#x2014;X&#x2014;&#x2003;&#x2003;(I)wherein X is the residue of a cyclic or acyclic sugar alcohol which is substituted with at least one &#x2014;R; &#x2014;C(O)R; &#x2014;(CHCHO)(CH(CH)CHO)R; &#x2014;(CHCHO)(CH(CH)CHO)C(O)R; 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 Ris independently a linear or branched alkyl group having 5 to 29 carbons optionally comprising at least 1 unsaturated bond; and each Ris independently &#x2014;H, a linear or branched alkyl group having 6 to 30 carbons optionally comprising at least 1 unsaturated bond, or mixtures thereof.

Use of non-fluorinated or partially fluorinated urethanes in coatings

A method of treating a substrate comprising contacting the substrate with a composition comprising i) a wax which provides a surface effect and ii) a polymer extender composition comprising a urethane based compound, a composition for treating a substrate, and treated substrates thereof.
