Abstract
The application relates to a low viscosity and to a stable fabric softening composition process for the preparation of a stable, and particularly to a viscosity stable, fabric softening composition having a low viscosity, said composition comprising from about 1 to 18 wt. % of an oligomeric esteramine or oligomeric esterquat, obtainable by reaction of an alkanol amine with a polycarboxylic acid and with a fatty alcohol and optionally a fatty acid, optionally followed by quaternization. The process comprises melting said oligomeric esteramine or oligomeric esterquat, dispersing said melted material in hot water, and subsequently cooling. In a second aspect, the application relates to a process wherein a thickening agent or mixture of thickening agents is added to the hot water containing the melted material or after the hot water has cooled. This thickening agent is selected from the group consisting of modified cellulosic polymer, non-ionic viscosity modifier, associative thickener and polyacrylate.
