摘要： An ophthalmic lens suited for extended-wear for periods of at least one day on the eye without a clinically significant amount of corneal swelling and without substantial wearer discomfort. The lens has a balance of oxygen permeability and ion or water permeability, with the ion or water permeability being sufficient to provide good on-eye movement, such that a good tear exchange occurs between the lens and the eye. A preferred lens is a copolymerization product of a oxyperm macromer and an ionoperm monomer. The invention encompasses extended wear contact lenses, which include a core having oxygen transmission and ion transmission pathways extending from the inner surface to the outer surface.

摘要： A polydextrose having improved color, flavor and decreased reactivity toward food ingredients having amine functionality. The polydextrose comprises a water-soluble highly branched polydextrose having been prepared by a process which comprises melting dextrose in the presence of a food-acceptable acid catalyst. The improved polydextrose of this invention has substantially no reducing glucose groups. Another aspect of this invention is directed to a method of making the above-described improved polydextrose which comprises exposing unimproved polydextrose to an environment capable of chemically transforming the reducing glucose groups contained in the unimproved polydextrose, thereby substantially eliminating their reducing properties. An improved polymaltose prepared by heating maltose in the presence of a food-acceptable acid catalyst and chemically transforming the reducing glucose groups contained in the polymaltose, thereby eliminating their reducing properties, is also described.

摘要： A method of imparting improved conditioning properties to hair comprising treating the hair with a composition comprising a water-soluble quaternary ammonium compound, such as cetrimonium chloride; an oil-soluble, water-dispersible quaternary ammonium compound, such as distearyldimonium chloride; an acid-neutralized amidoamine compound, wherein an amidoamine having the general formula: ##STR1## wherein R.sub.1 is a fatty acid chain containing from about 11 to about 21 carbon atoms, R.sub.2 is an alkylene group containing from two to about four carbon atoms, R.sub.3 is hydrogen, methyl, ethyl or a hydroxyalkylene group containing from one to about three carbon atoms, R.sub.4 is methyl, ethyl or a hydroxyalkylene group containing from one to about three carbon atoms, and Y is a heterocyclic nitrogen-containing moiety, like morpholine or pyridine, is neutralized with a suitable acid, such as the amidoamine compound stearamidoethylethanolamine neutralized with phosphoric acid; and a low molecular weight polydimethylsiloxane compound, such as cyclomethicone. The method and composition unexpectedly provide improved hair-conditioning properties such as wet feel, wet and dry combing, manageability, sheen, luster, body and overall hair condition.

摘要： A cross-linked urea-formaldehyde polymer matrix is formed by catalyzing, using a buffered acid as the catalyst, an aqueous mixture of a urea-formaldehyde concentrate, urea-formaldehyde resin, and powdered urea. The resulting thermoset polymer which possesses, in part, a cyclic structure, is of unusual hardness and has utility, with or without fillers, as a molding or casting material possessing controllable shrinkage characteristics because of uniform molecular structure and formula versatility.
