  • Patent number: 5080848
    Abstract: The present invention relates to an energy saving process for preparing concentrated or condensed surfactant granules. High active surfactant paste is chilled and granulated using fine dispersion mixing. The product surprisingly provides discrete, uniform (200-2,000 micron) granular particles. The granules of the present invention are preferably pure surfactant to be used as an intermediate in a final detergent formulation.

  • Patent number: 4925585
    Abstract: The present invention relates to an energy saving process for preparing condensed detergent granules. Dry detergent builders and a high active surfactant paste are finely dispersed into a uniform dough. The dough is chilled and granulated using fine dispersion mixing to surprisingly provide discrete, uniform (300-1200 micron) free flowing, granular particles. The granules of the present invention are preferably formulated to be fully formulated.

  • Patent number: 4395342
    Abstract: A comelted, granular fabric softening composition which is water dispersible in the cold water rinse of a washing machine, comprising about 60% to about 85% of a di-(long chain) quaternary ammonium salt and about 15% to about 40% of a mono- (long chain) quaternary ammonium salt having from 10 to 14 carbon atoms in its single long chain. The fabric softening composition may also contain up to about 25% of optional ingredients. In one embodiment of the invention the fabric softening agent is adapted to be placed within a water-permeable envelope. The envelope can be inserted into a washing machine during a laundering operation to provide fabric softening benefits to the clothes being laundered.
