Definitions

• the present invention relates to a laundry detergent composition having a lenticular size and shape, and to a process for making such lenticular detergent compositions.
• compositions that are in the form of lenticles.
• These solid particles are of a shape and size that exhibit improved physical performance characteristics compared to the conventional particulate detergent products. For example, dosing from the container, especially a bottle, can be improved compared to conventional laundry detergent powders.

• the lenticular particles often have the form of a surfactant-rich core surrounded by a coating layer. Hence there is an interest in processes that can change the properties of the surfactant-rich cores through process conditions such as shear rate and temperature so as to increase dissolution behaviours.

• the degree of the alignment of the lamellar sheets is related to the shear rate the material is subjected to as it passes through the orifice and the amount of time this shear is applied for. The greater the applied shear rate the greater the degree of surfactant lamellar alignment.
• the degree of alignment and structure that is in the extruded material and hence any resultant extrudate has an impact on the rate of dissolution of the extrudates. This is because the surfactant bilayers which actually form the lamellar surfactant phases dissolve by the action of the bilayers becoming detached from each other due to the solvation from the water. Hence the nature of the processing conditions of the extrudates can be expected to have some impact on the rate of dissolution of the extrudates.
• SAXS Small Angle X-Ray Scattering techniques
• SAXS analysis was caried out on the extrudates as follows: A Xenocs Xeusss 2.0 machine was used equipped with a Pilatus 200k detector and a Cu Genix source. The sample to detector distance was 363mm as per manfacturers recommendations for surfactant type materials.
• the data was recorded using a 2D detector so as to allow measurement of the degree of orientation of the lamellar phase.

• 245g of a 50% active sodium hydroxide solution were gradually added to the HLAS over a 5 minute period with vigorous stirring so as to avoid excessive generation of heat.
• the stirring was continued at a medium speed for a further 20 minutes to allow the reaction to complete.
• the stirring was then stopped and the paste allowed to cool to ambient. This formed a high active paste of sodium linear alkylbenzene sulphonate of 82% active (by wt) with the balance being water and miscellaneous (such as unsulphonated material).
• the LAS paste described above was then converted to a surfactant powder containing LAS, AE7 nonionic surfactant (Neodol 45-7) and Polyethylene Glycol 4000 as follows. 91.3g of the LAS paste described above were vigorously mixed by hand with 7.3g of warm (hence liquid) Neodol 45-7 and 1.5g of molten PEG 4000. The nonionic surfactant and the PEG4000 were easily blended into the LAS paste to make a visually homogenous paste. This paste mixture was then dried in an oven at 90 °C for 48 hours to make a hard and dry material. This material was then ground in a domestic coffee grinder to make a fine powder which was passed through a 425 micron sieve.
• the equilibrium relative humidity of the powder was measured to be 6% at 23 °C.
• the composition of the surfactant powder was calculated (based on measurement of weight loss) to be 88.4% LAS, 8.6% AE7, 1.8% PEG 4000 with the balance being water and miscellaneous.
• This powder was then divided into three batches and used to make surfactant extrudates at different shear rates as follows. All tests were done at ambient temperature ( ⁇ 20 °C) with no sources of external heating or cooling on the die or piston.
• - 30g of surfactant powder was loaded into a die consisting of a circular steel cylinder of length 100mm and internal diameter 26mm. One end of the die was open to allow entry of a suitable piston or punch and in the other end there was a 5mm diameter circular orifice located axisymmetrically. The length of the orifice through the steel of the die was 3mm.
• the loaded die was suitably mounted on an Instron 3369 Compression Tester and a suitable punch placed in the die such that it closely fitted the internal diameter but could still be moved without excessive force.
• the punch loosely compressed the surfactant powder.
• the crosshead of the Instron was moved such that the load cell of the Instron (model 2525) forced the punch down at a controlled speed. This first compressed the surfactant powder and then forced the surfactant powder to be extruded through the orifice at a controlled constant speed. This was continued until all the surfactant powder had been extruded.
• the test was carried out at three different crosshead speeds (0.1mm/minute, 0.5mm/minute and 5mm/minute) using ⁇ 30g portions of the powder made above. This gave three separate examples of extrudates made at different crosshead speeds and thus different shear rates in the orifice.
