Abstract: A water repellant composition for imparting water-repellancy to fibrous materials comprises an oxidized wax having a molecular weight of at least 750 (e.g. in 12.5 to 87.5% by weight), a fatty ketone having from eighteen to sixty carbon atoms (e.g. in 12.5 to 87.5% by weight) and optionally a cross-linking agent which is capable of resin forming polymerization and of reaction with ketones, carboxylic acid groups (present in the oxidized wax) and active hydrogen groups in the fibrous material. Specified oxidized waxes are oxidized polyolefins (such as oxidized polyethylene, polypropylene or polybutene), oxidized Fischer-Tropsch wax and oxidized microcrystalline wax.  Of the many possible ketones listed those used in the examples are stearone, laurone and methyl heptadecyl ketone. The composition may be applied to fibrous materials in the form of an aqueous emulsion which may contain an emulsifying agent preferably of the non-ionic type, or may be applied as a solution in an organic solvent such as chlorinated hydrocarbon, a ketone or an aliphatic ester (in particular tetrachloro-ethylene is used).  The cross-linking agent may be an aldehyde, a methylol melamine, a dimethylol urea, an intermediate stage melamine-formaldehyde resin, a water-dispersible stage resin derived from an aldehyde, or an epoxy-polyol resin and many examples of each class are listed.  The cross-linking is preferably effected in situ on the fibrous material, e.g. by heating. Optional composition ingredients are fluorine containing oil repellants such as a fluoro-carbon Werner complex or a polyperfluoroacrylate, alkaline materials to reduce acidity (hydroxides, amines and alkaline salts are specified), viscosity increasing agents such as cellulose ethers, and unspecified dyes, pigments, textile lubricants, moth-proofing agents, flame-proofing agents, shrink-proofing agents, brightening agents, sizes, paper-making chemicals, mildew-proofing agents, leather-treating agents, and softening agents.  The examples illustrate the application of typical compositions resistant to laundering and dry cleaning, to fibrous materials selected from wool, cotton, silk, ramie, jute, cellulose, wood, leather, paper, hemp, sisal, linen, maguey, viscose rayon, acetate rayon, nylon, polyacrylonitrile, polyvinylidene chloride, vinyl chloride/acrylonitrile copolymers, polyvinyl alcohol, terephthalic acid/glycol polyesters, zein, peanut protein, casein, alginates, mineral wool and fibrous glass.  The compositions also find application as furniture or floor polish.ALSO:A water repellant composition for imparting water-repellency to fibrous materials comprises an oxidized wax having a molecular weight of at least 750 (e.g. in 12.5 to 87.5% by weight), a fatty ketone having from eighteen to sixty carbon atoms (e.g. in 12.5 to 87.5% by weight) and optionally a cross-linking agent which is capable of resin forming polymerization and of reaction with ketones, carboxylic acid groups (present in the oxidized wax) and active hydrogen groups in the fibrous material.
