  • Patent number: 5358647
    Abstract: A fabric softening product is a composition or article that is effective for its fabric softening purpose but preferably excludes ecotoxic quaternary ammonia salt, includes, as a fabric softening component, a PEC, which is an ester of pentaerythritol, an ester of an oligomer of pentaerythritol, an ester of a lower alkoxylated pentaerythritol or an ester of a lower alkoxylated pentaerythritol oligomer, with bentonite, which increases its fabric softening effect remarkably. The PEC is preferably a partial higher fatty acid ester of pentaerythritol or a partial higher fatty acid ester of a pentaerythritol oligomer, the bentonite is preferably sodium bentonite or swellable calcium bentonite, the fabric softening composition is a softergent or a non-detersive composition, both of which may be in solid (preferably particulate solid) or liquid state or form (preferably in aqueous suspension or gel), and the fabric softening article is an absorbent material with bentonite and PEC deposited on it or absorbed by it.

  • Patent number: 5290459
    Abstract: A fabric softening composition or article that is effective for its fabric softening purpose but does not include ecotoxic quaternary ammonium salt, includes, as a fabric softening component, an ester of pentaerythritol, an ester of an oligomer of pentaerythritol, an ester of a lower alkoxylated pentaerythritol or an ester of a lower alkoxylated pentaerythritol oligomer. The fabric softening component is preferably a partial higher fatty acid ester of pentaerythritol or a partial higher fatty acid ester of a pentaerythritol oligomer, the fabric softening composition is an aqueous emulsion or a particulate or powder composition (preferably with the carrier of the powder composition being a fabric softening bentonite) and the fabric softening article is an absorbent material with fabric softening component deposited on it or absorbed by it.

  • Patent number: 4960526
    Abstract: A water-soluble diammonium compound, such as N-methyl-N-(2-hydroxyethyl)-N-tallowalkyl-N'-methyl-N'-bis(2-hydroxyethyl) -propylene-diammonium methosulfate, is homogeneously and finely dispersed in a spray-dried detergent bead or granule. The spray-dried bead is blended with a clay mineral fabric softener. The final composition exhibits antistatic action even at low levels (e.g. less than 2%) of the antistat without adversely effecting softening, cleaning or whitening. In a typical formulation, the spray-dried beads include linear alkyl benzene sulfonate or other anionic surfactant, an inorganic polyphosphate and/or other inorganic and/or organic detergent builder salt, diammonium compound antistatic agent, and other heat stable and pH insensitive detergent additives and fillers.
