- 1 C. 1341 FABRIC CONDITIONING COMPOSITION
This invention relates to a fabric conditioning composition paxticularly suitable for the conditioning (eg softening) of fabrics in the rinse step of a fabric laundering process.
It is known to add fabric conditioning agents, particularly including fabric softening materials, to the rinse step of a fabric laundering process. These fabric softening materials are often cationic materials, for example quaternary ammoni~m salts.
One may wish to avoid or reduce the use sf quaternary ammonium salts for reasons of cost and processing difficulties, Nonionic abric conditioning agents are known, but when incorporated in compositions for treating fabrics from the rinse they sllfer from the disadvantage of not being efficiently deposited on the abricO
We have now discovered that the deposition o nonionic fab.ric conditioning agents can be improved by 6~ C. 1341 incorporating aluminium chlorhydrate in the fabric conditioning composition.
Thus, according to the invention there is provided a method of conditioning fabrics in the rinse step of a fabric laundering process in which fabrics are brought into contact with an aqueous liquor to which has been added a liquid or granular solid composition comprising a nonionic fabric conditioning agent, optionally a cationic fabric softening agent in an amount by weight which is less than that of the nonionic fabric conditioning agent and in which composition anionic surface active materials are absent or substantially absent, characterised in that said composition further contains aluminium chlorhydrate.
Aluminium chlorhydrate is a material which has a low degree of ionisation in the product to prevent coagulatlon and phase separation of the fabric conditioning materials.
The fabric conditioning composition for use in the invention includes at least one nonionic fabric conditioning agent. This material will normally be a nonionic fabric softening agent, but other nonionic fabric conditioning agents including nonionic anti static agents may also be included.
Typical nonionic fabric softening agents include the fatty acid esters of mono- or polyhydric alcohols, or anhydrides thereof, containing from 1 to 8 carbon atoms such as sorbitan esters including sorbitan monostearate, and sorbitan tristearate, ethylPne glycol ester including ethylene glycol monostearate, glycerol esters including glycerol monostearate, alkyl mono- or di-alkanolamides such as palm or tallow mono ethanolamide and tallow di-ethanol-amide, and other such materials disclosed in GB 1 550 206.
.~,~ ., 5~;~
- 3 - C.1341 Alternative nonionic fabric softening agents include lanolin and lanolin-like materials such as acetylated lanolin.
The fabric conditioning composition for use in the invention may optionally also include at least one cationic fabric softening material. Suitable cationic fabric softening materials and mixtures thereof axe well known in the art, particularly from Schwartz, Perry &
Berch, "Surface Active Agents" (Vol I and II), from Davidson & Milwidsky, "Synthetic Detergents" ~6th edition, John Wiley Sons 1978~ and from Gutcho, "Household and Industrial Fabric Conditioners" (Noyes Data Corporation 1980). The readerls attention is .
directed to these documents for lists of suitable cationic fabric softening materials.
In particular, the present invention is of advantage if the cationic fabric softening material is an alkyl quaternary ammonium salt of the general formula RlR2R3R4N+X-where R1 and optionally R2 is a substituted or unsubstituted, saturated or unsaturated, straight or branched chain alkyl group having 8 to 22 carbon atoms, R3, R4 and optionally R2 is an alkyl or substituted alkyl group having 1 to 4 carbon atoms and X is an anion. An alternative class of cationic fabric conditioning agents are the imidazolinium compounds of the general formula CH -CH

Specific examples of suitable cationic fabric softening materials include cetyl trimethyl ammonium bromide, dihardened to llow dimethyl ammonium chloride (available us Arquad 2HT), dist~earyl dimethylammonium chloride lavailable as Arosurf TA100), l-methyl-l-oleyl-amido-ethyl-2-oleylimidazolinium methosulphate and the disoft tallow equivalent available as Varisoft~475).
The fabric conditioning composition for use in the invention may also include other cationic fabric conditioning materials, such as cationic anti-static materials. When cationic fabric softening materials are included, the weight ratio of the cationic fabric softening material to the nonionic fabric softening material should be less than about 1:1, such as less than about 1 3.
nionic surface active materials should be absent or substantially absent from the compositions. By "substantially absent", we mean that the weight ratio of any anionic material to the nonionic fabric conditioning agent is less than about l:10, most preferably less than about 1:20.
The fabric conditioning compositions used in the method according Jo the invention may be in liquid or granulax solid formO
C/.o~ de ~csv us so - 5 - C.1341 When in liquid form, the composition may be in the form of a dilute rinse conditioner (containing say up to about 20% total active material) or in concentrated form. Suitable formulations for concentrated rinse conditioners will include viscosity control agents such as are disclosed in GB 2 053 249 (Unilever Limited) where the compositions contain materials such as polyethylene glycol and US 4 149 978 (Goffinet assigned to The Procter and Gamble Company) where the compositions contain hydrocarbons The fabric softening compositions optionally contain one or more nonionic emulsifying agents, such as the polymerised monoglycerides of long chain fatty acids having from 14 to 24 carbon atoms in the straight or branched saturated or unsaturated carbon chain, such as poly monolauryl glyceride, poly-monostearyl glyceride, poly-monopalmityl glyceride or poly-msnooleyl glyceride.
These nonionic emulsifying agents are available commercially by the Trade Marks WITCONOL (Witco Chemicals Limited and TWEEN (Atlas Chemical). The nonionic emulsifying agent may be present at a level from about 0.1 to about 10~ by weight, such as from about 0.5% to about 6g.
In dilute liquid fabric conditioning compositions the total concentration o the fabric conditioning agent (that is the nonionic fabric conditioning agent and the cationic fabric conditioning agent, if any) may by from about 0.5% to about 30~ by weight, preferably from about 1.5% Jo about 10% by weight. The aluminium chlorhydrate may occupy from about 0O1% to about Z.5% by weight, preferably from about 0.25% to about 1.0% by weight.
5~1 - 6 - C.13~1 The ratio of the fabric conditioning agent (or agents) to the alumniumum chlorhydrate is preferably at least about l.5:l, and less than ahout 40:l by weight, most preferably from about 4:l to about 20:l. In concentrated liquid fabric conditioning compositions the concentration of the fabric conditioning agent (or agents1 may be from about 10% to about 60% by weight, preferably from about 30~ to about 50% by weight. In this case the ratio of the fabric conditioning agent (or agents1 to the aluminium chlorhydr~te is preferably from about 3:l to about 80:l, most preferably from about l0:l to about 60:l.
When in liquid form, the fabric conditioning composition will contain, in addition to the fabric conditioning agent (or agents) and the aluminium chlorhydrate, a liquid carrier such as an aqueous base which may consist only of water or of a mixture of water with other materials such as those referred to below.
The pH of the compositions may lie between about 3 and about l0, although products having a pH about 2 and about 3 are also possible. Suitable compositions can be prepaxed having a pH between about 3 and about 6. On dilution in the rinse liquor the pH will generally change to about 6 to about 8.
The compositions may further include materials conventionally added to fabric conditioning compositions such as buffering agents, organic solvents, emulsifiers, colouring materials, bactericides, antioxidants, fluorescers, perfumes, perfume carriers, bleaches and hydrotropes.
When the fabric conditioning compositions are in granular solid form, they may be prepared either by dry 5~
7 - C.1341 blending the ingredients or by adsorbing the ingredients on a solid carrier, such as silica or urea.
Alternatively the compositions may be formed into a slurry which is subsequently spray dried. In the case of a solid composition it is preferred that the composition contains from about 0.5~ to about 85% by weight of the fabric conditioning agent (or agents), more preferably from about 2~ to about 25~ by weight, while the aluminium chlorhydrate accounts for from 0.1% to about 8~ by weight, more prefexably from about 0.3% to about 2.5% by weight. The remainder of the solid compssition will be made up of the solid carrier optionally together with the conventional additives for solid fahric conditioning compositions, such as those listed above for liquid compositions.
The aluminium chlorhydrate included in the compositions may confer other benefits, once deposited on the fabric. Thus, in addition to improving the deposition of the nonionic fabric conditioner, it may act as a deodorant, a germicide, an anti redeposition material, an anti-static material, an anti-yellowing material, an ironing aid, an anti-grease agent, a perfume carrier, or an anti-oxidantO
Compositions for use in the present invention may be prepared by a variety of methods. One suitable method, in the case of diiute liquid fabric conditioning compositions, is to form a molten premix consisting of the fabric conditioning agent (or agents), water and optionally a sslvent and adding the aluminium chlorhydrate to this molten premix in the presence of sufficient water to give the desired dilution in the product.
The invention will now be further illustrated by the following ~on-limiting Examples.

Claims (6)
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A method of conditioning fabrics in the rinse step of a fabric laundering process in which fabrics are brought into contact with an aqueous liquor to which has been added a liquid or granular solid composition comprising a nonionic fabric conditioning agent, optionally a cationic fabric softening agent in an amount by weight which is less than that of the nonionic fabric conditioning agent and in which composition anionic surface active materials are absent or substantially absent, characterised in that said composition further contains aluminium chlorhydrate.
2. A method according to Claim 1, characterised in that said composition is a solid composition comprising said nonionic fabric conditioning agent and said aluminium chlorhydrate supported on a carrier.
3. A method according to Claim 2, characterised in that said composition contains from about 0.5% to about 85% by weight of the nonionic fabric conditioning agent together with the cationic fabric softening agent, if any, and from about 0.1% to about 8% of aluminium chlorhydrate, the balance comprising a solid carrier.
4. A liquid fabric conditioning composition for use in the method according to Claim 1, comprising an aqueous base, at least about 0.5% by weight of a nonionic fabric conditioning agent, optionally a cationic fabric softening agent in an amount by weight which is less than that of the nonionic fabric conditioning agent and in which composition anionic surface active materials are absent or substantially absent, characterised in that the composition further comprises aluminium chlorhydrate.
5. A composition according to Claim 4, characterised in that it further contains one or more nonionic emulsifying agents.
6. A composition according to Claim 4, characterised in that it contains from about 0.5% to about 30% by weight of said nonionic fabric conditioning agent and from about 0.1% to about 2.5% by weight of aluminium chlorhydrate.
