- Fig 2 shows reflectance values against wash number in multi-cycle soil wash experiments employing white cotton (Fig 2A) and blue cotton (Fig 2B) pieces and powder fabric softener compositions with ( ⁇ ) and without (*) lipase
- Figs 3A and 3B show visual ranking scores on a scale of 4 for dirtiest to 1 for cleanest for white cotton (Fig 3A) and blue cotton (Fig 3B) pieces, washed in multi-cycle soil wash experiments employing powder fabric softener compositions with (hatched shading) and without (solid shading) lipase.
- the storage stability of LipolaseTM (100T encapsulate) a lipase from Novo Nordisk A/S, in the following solid (powdered) compositions was investigated.
- the 100T material is a non-dusty encapsulate comprising a binder/filler and Lipolase enzyme at an activity level of 100 NOLU/mg.
- NOLU is a lipase activity unit defined and determined by Novo according to a method described in their document AF95/5 available on request from Novo Nordisk A/S, Novo alle, DK-2880 Bagsvaerd, Denmark.
- each composition When diluted to a concentration of lg/litre each composition gives a lipase concentration of 5 NOLU/ml.
- compositions were stored at 25°C for at least 42 days and the stability of the enzyme in the composition was assessed by measuring the variation of enzyme activity with time.
- Lipase activity was determined by measurement of fatty acid production on olive oil soiled polyester according to the following method. 0.4g of olive oil was pipetted onto a 2.5cm 2 piece of polyester fabric. The cloth was allowed to stand overnight to allow the oil to spread evenly through the fabric. 3g of rinse conditioner containing Lipolase was then dissolved/dispersed in 97ml water.
- composition C with lipase
- composition D (without lipase)
- the evaluation was carried out under Japanese wash conditions in a Japanese washing machine with Kao's AttackTM (lg/L) as the main wash product.
- Kao's AttackTM lg/L
- a ten minute wash cycle with 35 litres of water, and a five minute rinse cycle with 40 litres of water were employed.
- the water employed was of 6°FH and had a temperature of 20°C.
- MCSW multi-cycle soil wash
- the wash load contained the following test pieces: 5 white (24 x 12 cm) and 5 blue (16 x 11 cm) soiled cotton pieces. 1 piece (30 x 22 cm) of AS8 cloth, a new piece for each wash cycle.
- the load v. r s made up to 1.1 kg with ballast containing a 50:50 mixture of cotton sheet and terry towelling.
- the white and blue cotton was soiled with standard multi cycle soil solution, which is a complex mixture containing olive oil, protein and an inorganic pigment. Soiling was performed by the following method. 3 days prior to starting the multi cycle test the fabric was soaked for 1 hour in a beaker of multi cycle soil. Excess soil was then removed by passing the fabric through a padder. After drying, additional soil was rollered on using the padder and the fabric dried again and then left to age. Additional soil was added between each wash cycle by rollering on with the padder.
- Figures 2a and 2b show the reflectance data obtained for the powder rinse conditioner with and without Lipolase.
- the reference values obtained can be compared with the R460 value for clean white cotton, which is 88.75, and that for clean blue cotton, which is 24.15.
- the product with Lipolase is seen to give significant cleaning benefits en white cotton, which benefits increase in size as the number of wash cycles is increased. Perhaps most surprising is the size of the benefit obtained with the Lipolase containing powder after a single cycle. This benefit cannot be attributed to any between-wash action and must occur simply as a result of Lipolase action and consequent soil removal during the rinse.
- the reflectance data is less clear but in general both Lipolase products performed as well as, or better than, the controls.
- the level of residual fat on the test cloths was determined at the end of the 5 wash cycles by solvent extraction (dry cleaning method) .
- the test cloths which had been treated with the Lipolase containing products had lower residual fats than the corresponding controls (Table 1) .
- the reduction in fat being 21.9% on white cotton with the 2HT/Bicarbonate Powder. 5.7% on blue cotton with the 2HT/Bicarbonate Powder.
- the trends in the residual fat data are clearly in line with the reflectance data ( Figure 2) .
- Lipolase As well as cleaning performance, it is desirable that the incorporation of Lipolase into a rinse conditioner does not greatly reduce softening. This could result from the Lipolase affecting the stability of the cationic dispersion or as a consequence of the Lipolase reducing the fat content of the fabric.
- Table 2 sets out examples of suitable base formulations of composition according to the present invention, and containing dimethyl dihardened tallow ammonium chloride (Arquad 2HT) as a cationic fabric softener.
- Arquad 2HT dimethyl dihardened tallow ammonium chloride
- compositions are suitable for use as powders or may be formed into tablets.
- Table 3 exemplifies formulations containing 1,2 ditallowoxytrimethyl ammonium propane chloride (HEQ) as cationic fabric softener.
- HEQ 1,2 ditallowoxytrimethyl ammonium propane chloride
- compositions J and K may be powders or tablets. Other compositions are more suitable for use as powders.
- Table 4 exemplifies three further solid formulations containing ester-linked cationic fabric softeners: Table 4
- Sodium Chloride 10 10 10 by weight MicrosilTM carrying a total of 5% by weight perfume and lipase may be added.
- Other optional ingredients such as antifoam, dye, and preservative may, of course, also be added.
- NDEQ is the corresponding methosulphate salt of HEQ
- R is a partially hardened tallow group.
