- the level of solvent materials as referred to above is less than the level of cationic fabric softener materials in the composition. More preferably the level of solvents is less than 75 %, more preferred less than 50 % based on the weight of the cationic fabric softener material. Typically compositions of the invention are substantially free from solvents.
- the fabric-treatment composition according to the invention also comprises a small amount of water-soluble, cationic material.
- suitable materials of this nature are given in GB-A-1,601,360.
- Other suitable water-soluble cationic materials include polyamine materials, preferably diamine materials, wherein each nitrogen atom is connected to three other atoms.
- a preferred diamine, water-soluble, cationic material of this nature is Ethoduomeen T13 (ex AKZO) which comprises an N,N',N'-tris (2-hydroxyethyl) N-tallow 1,3-diaminopropane.
- the amount of water-soluble, cationic material is preferably less than the amount of water-insoluble, cationic material.
- the amount of water-soluble, cationic material will preferably be from 0.5 to 10% by weight of the composition.
- compositions according to the invention can be prepared by any method suitable for preparing dispersed, emulsified systems.
- a preferred method involves the forming of a molten pre-mixture of the active materials in water at an elevated temperature, adding additional water to obtain the desired active concentration, and then cooling to ambient temperature. When desired, some minor ingredients such as electrolytes, colouring agents, etc. may be post-dosed.
- a second preferred method involves the forming of the product by phase inversion of a water in hydrocarbon emulsion, wherein the cationic softener is either part of the hydrocarbon phase or is added as a separate dispersion after phase inversion. This method is especially advantageous, because this provides very finely divided hydrocarbon particles in the final product.
- the fabric-treatment compositions according to the invention are preferably used in the final rinse of the washing cycle of an ordinary washing machine.
- the amount of fabric-treatment composition to be added is mainly dependent on the active concentration of the composition and the volume of the water used in the rinsing cycle.
- the dose is chosen such that the concentration of active material (softener plus hydrocarbon material) in the rinse water is from 0.05 to 3.0 g/l, preferably from 0.5 to 2.0 g/l.
- Fabric-treatment compositions A-D were prepared as follows: The cationic materials and the hydrocarbon materials were mixed, melted and heated to a temperature of 70°C. The molten actives were added to water of 70°C while mixing at a high speed with a Silverson mixer. After being mixed for 10 minutes, the compositions were cooled to room temperature by rapid chilling in an ice bath while being gently stirred.
- compositions were tested as follows :
- the viscosity of the compositions was measured by a Haake viscometer at ambient temperature. Values are quoted at 110 S ⁇ 1.
- Fig. 1 The results of the tested compositions are represented in Fig. 1.
- This Figure clearly shows that the creasing score increases by decreasing the ratio water-soluble cationic material to hydrocarbon material. From the Figure it is clear that at ratios of 1:2 or higher, the viscosity of the compositions is unacceptably high. At ratios from 1:2 to 1:3, a significant decrease in creasing score is observed. At ratios of 1:4 and lower, a satisfactory creasing score in combination with an adequate viscosity is obtained.
- Fabric-treatment compositions were prepared according to the method as described in Example I. The following compositions were obtained :
- compositions were tested according to the method of Example I.
- the results of the tests are represented in Fig. 2. These results clearly illustrate a relatively high viscosity for compositions of a ratio water-insoluble cationics to hydrocarbon mixture of 1:3 and higher. An acceptably low viscosity is obtained when ratios lower than 1:3 are used.
- the results also illustrate a consistent decrease in wrinkling score in lowering the ratio from 1:2 to 1:3, and an unexpected increase in creasing score at ratios of 1:4 and lower. The combination of acceptable viscosity and adequate creasing score is only found at ratios of 1:4 and lower.
- compositions were made by preheating the Sirius 85, the Silkolene 920, the Adogen 462, the GMS and the Dobanol 25-3 to 60°C and adding water to this premix under stirring.
- This provides a water in oil type emulsion, which upon further addition of water is phase reversed to a oil in water type emulsion, wherein the oil phase is very finely dispersed.
- a predispersion of the Adogen 442 and the Etoduomeeen T13 which had been prepared by heating the two materials to 60°C followed by the addition to water under stirring.
- the final product is obtained by adding the remaining ingredients to the mixture of the two dispersions.
