Estimating the term…
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. Also within the invention are processes for softening fibrous materials, in washed laundry, by employing such compositions and articles, and processes for manufacturing the compositions.
A biodegradable fabric softening composition or article for application to laundry so that a fabric softening component thereof is deposited on the laundry and softens it, which fabric softening composition or article is non-toxic to aquatic organisms in waters into which waste waters containing such fabric softening component are discharged, which fabric softening composition or article comprises, by weight, 1% to 25% of the composition or article of a fabric softening component selected from the group consisting of a higher aliphatic C12-C22 ester of pentaerythritol, an oligomer of pentaerythritol, a C2-C3 alkylene oxide derivative of pentaerythritol or a C2-C3 alkylene oxide derivative of an oligomer of pentaerythritol, and mixtures thereof in or on a clay carrier for the softening compound and an adsorbent or cellular material, said carrier being 75% to 99% by weight of the composition or article and said composition or article being essentially free of quaternary ammonium compound fabric softener.
A biodegradable fabric softening composition in particulate or powder form for application to fibrous materials, so that the fabric softening component thereof is deposited on the fibrous materials and softens them, which fabric softening composition is non-toxic to aquatic organisms in waters into which waste waters containing such fabric softening component are discharged, which comprises, by weight, by weight, 1% to 25% of a fabric softening component selected from the group consisting of a higher aliphatic C12-C22 ester of pentaerythritol, an oligomer of pentaerythritol, a C2-C3 alkylene oxide derivative of an oligomer of pentaerythritol, and mixtures thereof, and 75%-99% of a clay carrier for said softening compound, said composition being essentially free of quaternary ammonium compound fabric softener.
