Abstract:
Disclosed is a method comprising: a step in which a polyoxirane derivative of PEGDE or PPGDE having a water-dissolving rate of not less than 95 % by weight is dissolved in a solvent which has a solubility parameter of 13.0-10.1 (cal/cm.sup.3).sup.1/2, has a boiling point in a range of 101.degree.-190.degree. C. and is freely soluble in water, so as to provide a water-soluble solution; a step in which the water-soluble solution is added with an aqueous solution containing at least two or more species of catalysts for oxirane compounds selected from the group consisting of dicyandiamide, hydroxy carboxylic acid salts, thiocyanate and L-cysteines so as to prepare a treatment solution; a step in which a protein fiber product is immersed in the treatment solution followed by dehydration; a step in which the dehydrated protein fiber product is subjected to a heat treatment so as to make a cross-linking reaction of the polyoxirane derivative with the protein fiber product; and a step in which by-products are removed from the heat-treated protein fiber product. The hygral expansion behavior of the protein fiber product is stabilized more surely without deteriorating its feeling, and the scarcely water-soluble by-products generated by the heat treatment are removed.
Abstract:
Coating compositions based on ethylene vinyl acetate polymers have improved compatibility with solvents (especially with aliphatic hydrocarbon solvents) hydrocarbon oils, and mineral waxes by blending the EVA with a fatty acid and heating at or above the melting point of the EVA. Furthermore the resultant blends are much more easily emulsified in the presence of cations than blends which have not been processed with the fatty acids. Typically the starting material for the improved product of this invention is a composition comprising a blend of an EVA polymer and a fatty acid which is miscible in all proportions with mineral spirits at 25.degree. C. or forms a solution at a level 5% of fatty acid in mineral spirits, such as coconut or palm fatty acids. Also disclosed is that the addition of a salt of an amine acetic acid in sufficient quantity to an acidified salt of zirconium (for example EDTA and zirconium acetate) forms a novel emulsifying agent, and this emulsifying system is used advantageously with the described EVA/fatty acid blends.
Abstract:
Polymeric-containing compositions having improved oxidative stability have the polymer and at least two stabilizing agents. These agents are selected from low temperature antioxidants such as alkali metal and alkaline earth metal hypo or hydrogen phosphites, high temperature antioxidants such as: alkali metal or alkaline earth metal phenylphosphonates, thioethers like dialkyl thioalkylionate and polymers thereof and metal deactivating agents like polydentate ligands and ethylene diamine-tetracidic acid compounds. The composition can be a coating composition for substrates including those like fibrous material including fibers, bundles of fibers, strands, roving, flakes and beads. The composition can be present as a dried residue on the substrate. For fibrous substrates, the composition also has at least one organofunctional silane coupling agent, may also have processing aids such as epoxy polyester polymers and/or lubricants. In addition, the polymeric-containing composition can have a crosslinking agent in an effective amount to produce a dried residue of limited swellability from the composition.

The weight ratio of amphoteric material to co-active being from 5:1 to 50:1. The amphoteric material is preferably an amine oxide. The composition may also comprise from 1-75% of a water-insoluble cationic fabric treatment compositions.
Abstract:
An aqueous single phase composition, particularly for use in the treatment of keratinous fibres, comprises a cationic polymer or mixtures thereof, an anionic monomer or mixtures thereof, and a solubilizing agent chosen from amphoteric detergent active compounds, inorganic electrolytes and mixtures thereof. The composition should have an anionic to cationic charge ratio of from 0.2 to 1.0. When the monomer is an anionic dye, the composition can be employed in the dyeing of hair.

In the formula, R.sup.1 is a linear C.sub.6 -C.sub.22 alkyl group, R.sup.2 and R.sup.3 independently of one another represent a linear or branched C.sub.1 -C.sub.6 alkyl radical, and x is a number of 3 to 20.
Abstract:
Disclosed are conditioning agents and compositions containing such conditioning agent, said conditioning agent being particles from about 5% to about 95%, by weight of said particles, of an amine-organic anion ion-pair complex and from about 95% to about 5%, by weight of said particles, of an amine-inorganic anion ion-pair complex. The particles have an average diameter of from 10 microns to about 500 microns. These conditioning agents can provide excellent fabric care benefits when applied as part of, or in the presence of, detergent compositions without significantly impairing cleaning performance.
