- a novel detergent composition can be formed which gives excellent softening properties and also excellent detergency.
- a fabric softening detergent composition comprising (i) a detergent surfactant comprising an amphoteric surfactant and/or a nonionic surfactant;
- a substantially water insoluble fabric softening compound comprising a compound having two C 12-22 alkyl or alkenyl groups connected to a quaternary ammonium head group via at least one ester link or a quaternary ammonium compound comprising of a single chain with an average chain length equal to or greater than C 20 ;
- a detergency booster wherein when constituents (i) and (ii) are diluted in water to a concentration of 5 wt% of (i) and (ii), at least 70 wt% of the fabric softening (ii) compound is in solution.

Where the composition is in a form containing water the composition itself may be at least partially in the form of self-size-limiting molecular aggregates. It is thought that it is this new structure of the fabric softening system within the detergent composition that overcomes the problems of the prior art.

- an amount of an alkali metal silicate particularly sodium ortho-, meta- or preferably neutral or alkaline silicate.
- alkali metal silicates at levels, for example, of 0.1 to 10 wt%, may be advantageous in providing protection against the corrosion of metal parts in washing machines, besides providing some measure of building and giving processing benefits.
- ingredients which may be present in the composition include fabric softening agents such as fatty amines, fabric softening clay materials, lather boosters such as alkanolamides, particularly the monoethanolamides derived from palm kernel fatty acids and coconut fatty acids; heavy metal sequestrants such as EDTA; perfumes including deodorant perfumes; germicides; pigments, colorants or coloured speckles; and inorganic salts such as sodium and magnesium sulphate.
- the formulation can also contain anionic surfactant, which, at a level of up to 100 mole%, preferably 50 mole%, of the cationic softener present, may promote the softening performance of the formulation.
- the detergent compositions according to the invention may be in any suitable form including powders, bars, liquids and pastes.
- suitable liquid compositions may be non ⁇ aqueous or aqueous.
- the compositions may be prepared by a number of different methods according to their physical form. In the case of granular products they may be prepared by dry- mixing, coagglomeration, spray-drying from an aqueous slurry or any combination of these methods.
- One preferred physical form is a granule incorporating a detergency builder salt. This may be prepared by conventional granulation techniques or spray-drying. It is preferred if compositions are in liquid form, especially preferred are transparent or translucent liquid detergents.
- the formulations detailed below were tested in model mixed load tergotometer experiments at a liquor:cloth ratio of 25:1.
- the fabric load used in each tergotometer pot comprised 3 pieces each of cotton terry towelling, cotton sheeting, 50/50 polycotton, and polyester, totalling 40g in weight.
- Each tergotometer run was performed three times. Wash treatments were done at 40°C for 15 minutes and were followed by a 5 minute rinse at ambient temperature. Fabrics were line-dried, following a short spin. Three wash-rinse- dry cycles were performed for each treatment prior to softness evaluation of the terry towelling and staining of each of the other fabrics with 0.05ml olive oil (highly refined, ex Sigma Diagnostics) containing a small amount of solvent violet dye. The stains were allowed to wick out for 4 days, prior to measurement of reflectance spectra and re- washing, together with the terry towelling, using the detergent system used for the pre-treatments.
- Softening of the fabrics was assessed by an expert panel of 4 people using a round robin paired comparison test protocol. Each panel member assessed four sets of test cloths. Each set of test cloths contained one cloth of each test system under a evaluation. Panel members were asked to assess softness on a 8 point scale. Softness scores were calculated using an "Analysis of Variance" technique. Lower values are indicative of better softening.
- Dobanol 91-5 is C9-C11 alcohol ethoxylate (5 EO) , ex Shell.
- Soil release polymer is a copolymer of poly(ethylene glycol methyl ether) , terephthalic acid, and glycerol as described in British patent applications 9513799.8 and 9518011.3.
- DMDAPS is 3- (Dimethyldodecylammonio) propanesulphonate, ex Fluka.
- Genapol C200 is coco-alcohol ethoxylate (20 EO) , ex Hoechst.
- HTTMAPC is 1,2 bis [dihardened tallowyloxy] 1-3 trimethylammonium propane chloride.
- the formulations containing builder were prepared by shearing the ingredients together in a Moulinex blender until an homogeneous slurry was obtained.
- the formulations containing SRP were prepared by equilibrating the ingredients together at 80°C, with occasional agitation, until an homogeneous solution/dispersion was obtained.
- nonionic surfactant - ethylene oxide condensation product comprising 1 mole of higher fatty alcohol of 12 to 15 carbon atoms and 11 moles of ethylene oxide.
- the formulations were prepared by equilibrating the ingredients together at 80°C, with occasional agitation, until an homogeneous solution/dispersion was obtained.
- Example 7 was a clear liquid, whilst comparative Example E was turpid and went cloudy on standing.
