Abstract
An aqueous fabric conditioning composition comprises a fabric conditioner, such as a cationic fabric softener, optionally an electrolyte, selected from ionic salts of lithium, sodium, potassium, calcium, magnesium and aluminum, at levels up to 0.5% together with a compound containing a transition metal ion, such as Cobalt (II) ions. The transition metal ion enhances bleaching of fabrics when they are subsequently washed in a bleach-containing detergent composition.
Claims2
A liquid fabric conditioning composition comprising from about 2 to about 25% of a fabric conditioner which is selected from the group consisting of alkylimidazolinium salts, quaternary ammonium salts having the formula:
- ##STR3## wherein R.sub.1 and R.sub.2 represent hydrocarbyl groups from about 12 to about 24 carbon atoms, R.sub.3 and R.sub.4 represent hydrocarbyl groups containing from 1 to about 4 carbon atoms, X is an anion, and mixtures of these salts, the composition being characterised in that it further comprises from about 0.04 to about 2.0% by weight based on the fabric conditioner of a compound containing a transition metal ion, selected from groups 4b-7b, 8 and 1b of the Periodic Table, said composition not containing a bleach.
