Abstract: A method for determining the anisotropy of the magnetic susceptibility of a sample includes determining the resonant frequency of the sample in substantially zero magnetic field, the resonant frequency being for flexure vibration in a selected plane of vibration. A second step is applying a uniform dc magnetic field to the sample, the magnetic field having a component in the selected plane of vibration. A third step is determining the resonant frequency of the sample in the presence of the applied magnetic field, the resonant frequency being for flexure vibration in the selected plane. The fourth step is determining the anisotropy of the magnetic susceptibility of the sample, based on the amplitude of the magnetic field component and on the above-determined resonant frequencies.

Abstract: Heavy duty liquid laundry detergent compositions which clean, soften and provide static control, and which comprise: (1) sulfated (optionally ethoxylated) alcohol anionic surfactant, (2) ion pair complex, (3) cumene, xylene, or toluene sulfonate, (4) smectite-type clay, and (5) ethoxylated nonionic surfactant. The compositions are in the form of stable, homogeneous suspensions which have a low viscosity, a near-neutral pH, and a specified yield value. Such compositions impart fabric care benefits through-the-wash without significantly impairing cleaning performance.

Abstract: Stable liquid detergent compositions containing amine oxide and alcohol polyethoxylate sulfate surfactants, a water-soluble detergency builder, an alkanolamine and a hydrotrope are disclosed. The compositions recover, after freezing, to single phase isotropic liquids at relatively low temperatures.

Abstract: Stable liquid detergent compositions containing nonionic, amine oxide and alcohol polyethoxylate sulfate surfactants and a water-soluble detergency builder are disclosed. The compositions are single phase isotropic liquids which exhibit improved freeze-thaw stability. The polyethoxylate sulfate surfactant enhances detergency performance on textiles that have been softened with a conventional cationic fabric softener.

Abstract: Granular detergent compositions comprising at least 15% sodium tripolyphosphate are prepared by agglomeration with an agglomerating agent comprising an alkali metal silicate solution such process comprising addition of such agglomerating agent to a first portion of sodium tripolyphosphate and the addition of a second portion of sodium tripolyphosphate to the mixture of said first portion and the agglomerating agent after at least about 30% of the agglomerating agent has been added.
