Definitions

• the present invention relates to a fabric conditioning composition, in particular the invention relates to aqueous dispersions of fabric conditioning compositions comprising a water insoluble quaternary ammonium material and a zwitterionic compound suitable for a rinse-added fabric softener compositions.
• Rinse added fabric conditioning composition are known.
• Such compositions contain a water insoluble quaternary ammonium fabric softening agent dispersed in water at a level of softening agent up to about 7 wt%, in which case the compositions are considered dilute, or at levels from 7 wt% to 50 wt%, in which case the compositions are known as concentrates.
• R-, R 2 and R 3 are each an alkyl or hydroxyalkyl group containing from 1 to 4 carbon atoms, or a benzyl group
• R 4 and R 5 are each alkyl chains containing from 11 to 23 carbon atoms
• X " is a water soluble anion.
• a further problem that arises in colder climates is when a fabric conditioner is transported or stored in a cold place the product gels to form a solid. In some cases the product does not recover and in others the time taken to thaw back to a liquid product frequently takes a couple of days. This poses a problem to supermarkets whom can not place the frozen product directly onto supermarket shelves.
• EP 280 550 and EP 507 478 disclose the use of selected nonionic stabilising agents to overcome the poor stability. However no mention is made of the instability of the formulation when perfume is added.
• US 3 984 335 discloses compositions containing a quaternised fatty amine and a fatty acid zwitterionic compound as a softening agent .
• Zwitterionic softening agents such as amine oxides are disclosed in EP 0 332 270 (Unilever) in combination with cationic softening agents and an amine.
• the problem of forming a concentrated fabric conditioner with relatively high levels of perfume is mitigated by the present invention. Furthermore the present invention aids recovery of a liquid fabric conditioner from a frozen state to a homogeneous liquid.
• the present invention claims a fabric conditioning composition comprising greater than 7 wt% of a water insoluble cationic fabric softening agent, characterised in that the composition further comprises a zwitterionic compound of the formula:
• R is an C 7 - 27 alkyl or alkenyl group

• Liquid fabric softening agents were made up as follows:
• the cationic fabric softening agent and nonionic stabilising agent were premixed and heated together to form a clear melt .
• the molten mixture thus formed was added over a period of at least one minute to water at ambient temperature with constant stirring to form a dispersion.
• Perfume was added to the aqueous mixture. Addition of the zwitterionic material occurred either
• HT TMAPC is 1,2 dihardened tallowyloxy trimethyl ammoniopropane chloride ex Hoescht.
• Tego betaine L is Alkyl amido propyl dimethyl amino acetic acid betaine ex Shell.
• Example 7 and Example G flocculated on addition of perfume. However Example 7 needed twice as much perfume to flocculate as Example G.
