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 soften- ing 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 penta- erythritol oligomer. The fabric softening component is prefer- ably 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.
