Definitions
- This invention relates to Rinse Conditioners comprising a softening or anti-static component.
- EP 111074 is typical and uses a silica to carry the softener.
- a disadvantage of using a carrier such as silica is that it bulks up the product and serves no function beyond making the powder compatible with other ingredients that may be contained in a washing powder.
- WO 92/18593 describes a granular fabric softening composition comprising a nonionic fabric softener and a single long alkyl chain cationic material.
- the specification teaches that effective cationic softening compounds when used in granular form exhibit poor dispersion properties.
- EP 569 184 discloses use of the granular composition to form a pre-dilute which is then added to the dispenser drawer of the washing machine.
- EP 568 297 discloses a granular fabric conditioner comprising a nonionic dispersing aid and a water insoluble cationic active having the formula: wherein each R 1 group is independently selected from C 1-4 alkyl, hydroxyalkyl or C 2 -C 4 alkenyl groups; and wherein each R 2 group is independently selected from C 2-27 alkyl or alkenyl groups and n is an integer from 0-5.
- EP 0 239 910 discloses this problem and attempts to solve it by limiting the pH range of aqueous formulations.
- the present invention mitigates the problems of both hydrolytic stability and of dispersion of a granular fabric conditioner.
- a powdered rinse conditioner comprising:
- the water insoluble cationic active has the formula: in which R 1 is a C 1 -C 4 alkyl groups, R 2 and R 3 are the same or different C 12 - C 22 alkyl or alkenyl groups, X - is a softener compatible anion.
- water insoluble cationic active is N,N-di(tallowoyl-oxy-ethyl) N,N-dimethyl ammonium chloride.
- the temperature of the rinse water is above 10°C, preferably above 20°C. However an acceptable level of softening is achieved below 10°C.
- the cationic active comprises more than 40% by weight of the powder and less than 95% by weight of the powder, more preferably the level of cationic active is greater than 60% by weight of the powder.
- the powder may also contain a co-active at levels of up to 20%.
- Preferred co-active are fatty acids.
- the ratio of cationic active:fatty acid is greater than 6:1. More preferably the ratio of cationic active:fatty acid is 12:1, most preferably 20:1.
- the fatty acid co-active may comprise hardened tallow fatty acid.
- composition of the invention also contains a wetting aid.
- a wetting aid may be defined as any material which promotes the ingress of water into the softening material thus aiding dispensing and dispersion of the material. In some instances the wetting aid may further boost softening.
- Preferred wetting aids are nonionic materials such as sugar alcohols, alcohol ethoxylates, (poly)ethylene glycols and mixtures thereof.
- alcohol ethoxylates preferably alcohol ethoxylates with a chain length between 9-20, most preferred due to superior biodegradability are alcohol ethoxylates with greater than 5 moles of ethylene oxide such as Dobanol 91-6EO (trademark ex Shell) and Genapol C100 (trademark ex Hoechst).
- the level of wetting aid is between 1 wt% and 20 wt%.
- the powder may also contain a flow aid and other ingredients commonly found in rinse conditioners such as perfume, antifoam, preservative, dye and dispersing aids such as low molecular weight cationics.
- a flow aid and other ingredients commonly found in rinse conditioners such as perfume, antifoam, preservative, dye and dispersing aids such as low molecular weight cationics.
- the quaternary ammonium material is biologically degradable.
- the invention is of particular use when applied directly to the rinse liquor.
- Example 1 Example A Example B DEEDMAC 89 - - Stepantex - 89 - Arquad 2HT - - 89 Perfume 3.8 3.8 3.8 Microsil 4 4 4 Genapol C100 3.2 3.2 3.2
- the dispersibility of the Examples in water was evaluated by weighing 5g of conditioner powder into a glass jar and adding 95g of demineralised water (at 20°C or 7°C). The jar was sealed and shaken for 2 seconds. The dispersion was filtered through pre-weighed polymon 43T (trademark) (150 ⁇ m) mesh. The mesh was then oven dried and the percentage residue calculated.
- Example 1 has superior dispersibility to examples A & B when the water temperature is 20°C.
- the softening properties on fabric of Examples A, B and 1 were evaluated by adding three 19 x 19 cm sqare of standard 8 terry towelling (40g) to cold US water. 1ml of sodium alkyl benzene sulphonate solution was added and the cloths stirred (80 rpm) for one minute. The cloth was removed from the pot and at the relevant time the product was added to the added to the solution. The cloths were added to the pot and stirred for 5 minutes. The cloths were removed, spun dry and line dried overnight.
- 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 evaluation. Panel members were asked to pick the softer cloth of each pair during evaluation. A "no difference" vote was not permitted. Softness scores were calculated using an "Analysis of Variance” technique. Higher values are indicative of better softening.
- Example 1 softens better than Example A and B.
