Definitions
- the present invention relates to a fabric softening composition, in particular the invention relates to aqueous dispersions of fabric softening compositions comprising a water insoluble quaternary ammonium material and a nonionic stabilising agent suitable as rinse-added fabric softener compositions.
- Rinse added fabric softeners 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 .
- EP 0 331 237 discloses the use of hydrophobically modified nonionic cellulose ether for use as a thickener for fabric conditioning compositions containing quaternary ammonium cations.
- Rj, R 2 and R- are each an alkyl or hydroxyalkyl group containing from 1 to 4 carbon atoms, or a benzyl group, R 4 and R are each alkyl chains containing from 11 to 23 carbon atoms and X " is a water soluble anion.
- EP 280 550 and EP 507 478 discloses the use of selected nonionic stabilising agents to overcome the poor stability.
- many nonionic stabilising agents create a further problem in that their presence destroys the viscosity of these fabric softening compositions.
- nonionic stabilising agents do not destroy the viscosity of fabric softening compositions containing a biodegradable quaternary ammonium material.
- the present invention relates to a fabric softening composition
- a fabric softening composition comprising: a) a water insoluble, quaternary ammonium material comprising one ester link and two C 12-28 alkyl or alkenyl groups;
- nonionic stabilising agent is a sucrose ester or an alkyl polyglucoside.
- a water insoluble, quaternary ammonium material having at least one ester link and two C 12-28 alkyl or alkenyl groups
- a nonionic stabilising agent which is either a sucrose ester or an alkyl polyglucoside
- the present invention is a way of controlling the viscosity of a fabric conditioner composition containing a biodegradable quaternary ammonium material and a nonionic stabilising agent.
- Suitable nonionic stabilising agents include the sucrose esters such as sucrose distearate and sucrose monostearate, and the alkyl polyglucosides such as stearyl monoglucosides and stearyl triglucoside.
- this invention is thought to operate in that the interaction of the hydrogen bonding elements of the molecules of the nonionic stabilising agent are essential to maintain a vesicular structure.
- a vesicular structure in the context of this invention can be defined as a spherical structure having onion ring shaped bilayers. The presence of such vesicular structures are an important factor in the formation of a composition with a commercially acceptable viscosity.
- the preferred level of nonionic stabilising agent present is 0.1 to 2.5 % by weight.
- sucrose esters Most preferred nonionic stabilising agents are the sucrose esters.
- the sucrose esters have the additional benefit that they impart additional softening benefits over the cationic softening agent .
- suitable sucrose esters include the Crodesta (Trademark (ex Croda) ) series. Crodestas are sucrose esters esterified with 70/30 mixture of stearic/palmitic acid to form a mixes of mono-ester, di-ester and triester. According to the manufacturer the levels of mono-ester are as follows:
- the fabric softening compound is suitably a substantially water insoluble quaternary ammonium material comprising a polar head group and two alkyl or alkenyl chains each having an average chain length greater than or equal to C 14 , and at least one ester group.
- the fabric softening compound of the invention has two long chain alkyl or alkenyl chains, each having an average chain length greater than or equal to C 16 Most preferably at least 50% of each long chain alkyl or alkenyl group has a chain of C ⁇ e
- the long chain alkyl or alkenyl groups of the fabric softening compound are predominantly linear.
- the fabric softening compounds used in the compositions of the invention are molecules which provide excellent softening, and characterised by a chain melting -L ⁇ to LO - transition temperature greater than 25°C, preferably greater than 35°C, most preferably greater than 45°C.
- This L ⁇ to L ⁇ transition can be measured by DSC as defined in "Handbook of Lipod Bilayers, D Marsh, CRS Press, Boca Raton Florida, 1990 (Pages 137 and 337) .
- Substantially insoluble fabric softening compounds in the context of this invention are defined as fabric softening compounds having a solubility less than 1 x 10° wt% in demineralised water at 20°C.
- the fabric softening compounds Preferably have a solubility less than 1 x 10 " X
- the fabric softening compounds have a solubility at 20°C in demineralised water from 1 x 10 "8 to 1 x 10 "6 .
- the fabric softening compound is a water insoluble quaternary ammonium material which comprises a compound having two C 12 _ ⁇ a alkyl or alkenyl groups connected to the molecule via at least one ester link. It is more preferred if the quaternary ammonium material has two ester links present.
- An especially preferred ester-linked quaternary ammonium material for use in the invention can be represented by the formula:
- each Rl group is independently selected from C ⁇ alkyl, hydroxyalkyl or C 2-4 alkenyl groups; and wherein each R- group is independently selected from C 8 _ 28 alkyl or alkenyl groups;
- X " is any suitable anion. 0 0
- T is -0-C- or -C-0-; and n is an integer from 0-5.
- Di (tallowyloxyethyl) dimethyl ammonium chloride is especially preferred.
- a second preferred type of quaternary ammonium material can be represented by the formula :
- R ⁇ X ⁇ n and R L are as defined above.
- Preferred materials of this class such as 1,2 bis [hardened tallowoyloxy] -3- trimethylammonium propane chloride and their method of preparation are, for example, described in US 4 137 180 (Lever Brothers) .
- these materials comprise small amounts of the corresponding monoester as described in US 4 137 180 for example 1-hardened tallowoyloxy-2-hydroxy-3- trimethylammonium propane chloride.
- the quaternary ammonium compound is biodegradable.
- Biodegradable in the context of this invention should be interpreted as meaning degrades to materials that are not known to be harmful to the environment .
- the ratio of quaternary ammonium material to nonionic stabilising agent is in the range from 5:0.5 to 5:0.1.
- the composition may also contain long chain fatty acid material for example C 8 - C 2i alkyl or alkenyl monocarboxylic acids or polymers thereof.
- long chain fatty acid material for example C 8 - C 2i alkyl or alkenyl monocarboxylic acids or polymers thereof.

- HEQ 1,2 bis [hardened tallowoyloxy] -3- trimethylammoniu propane chloride ex Hoechst.
- Liquid fabric softening agents were made up as follows:
- the cationic fabric softening agent and/or fatty acid and/or nonionic stabilising agent where appropriate 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 70°C to 80°C with constant stirring to form a dispersion.
- Viscosity was measured using the Haake RV20 Rotoviscometer. Viscosity is quoted at a shear rate of 10s "1 .
