  • Patent number: 4772403
    Abstract: Stable aqueous fabric softening compositions based on water-dispersible cationic fabric softeners such as the di-long chain, di-short chain quaternary ammonium salts are provided using synergistic proportions of fatty alcohols to enhance the softening performance. Both concentrated and ready-for-use formulations can be prepared. The active ingredients concentration in the concentrated formula is generally in the range of 11 to 20% by weight while for the ready-for-use formulations, concentration of the active ingredients may range from about 3 to about 8% by weight. In either case, the weight ratio of cationic softening agent to fatty alcohol being in the range of from about 4.5:1 to 3.5:1. These compositions have low viscosity and are easily dispersible in cold water and are storage stable. Water soluble electrolytes can further reduce viscosity and ethoxylated amines can further increase stability. Methods for making the compositions are also disclosed.

  • Patent number: 4725377
    Abstract: A liquid dishwashing detergent composition for hand washing of dishes in cold water includes a synthetic organic nonionic detergent, a cationic surface active agent, a water soluble C.sub.21 dicarboxylic salt and an aqueous medium. The proportion of the combination of nonionic detergent and cationic surface active agent is a detersive proportion, useful to remove fatty deposits on dishes, and the proportion of the C.sub.21 dicarboxylic salt is sufficient to improve the detersive action in cold water of the combination of nonionic detergent and cationic surfactant so that the composition better removes fatty deposits on dishes being washed.

  • Patent number: 4721581
    Abstract: Detergent laundry bars of acceptable mildness, foaming properties and processing characteristics are described which are based on built higher fatty alcohol ethoxylate sulfate detergent and which contain bentonite, which acts as a bodying agent for the laundry bars, facilitating production thereof, and contributes fabric softening properties to laundry washed with such laundry bar. When the bentonite is omitted or is replaced by water insoluble filler, such as calcium carbonate powder, bars made are not of acceptable hardness and such compositions are not satisfactorily processable in conventional soapmaking apparatuses.Also described are processes for converting aqueous solutions of higher fatty alcohol ethoxylate sulfate detergent to solid form by treatment with bentonite, and for making detergent laundry bars from such solidified detergent.
