Description

LAUNDRY COMPOSITION

Field of Invention

The present invention concerns the use of alkoxylated polyaryl or alkoxylated polyalkyl phenol with a cleaning cellulase.

Background of the Invention

Cellulases are enzymes that hydrolyse the glucosidic linkages in cellulose. They can be produced by a large number of bacteria, yeasts and fungi. In the laundry context cleaning cellulases are well-known which enhance the cleaning of cellulosic fabrics. Cleaning cellulases prevent re-deposition of soil from the wash liquor to fabrics reducing greying of fabrics. Cleaning cellulases do not cause significant fabric damage.

Cleaning Cellulases are discussed in Enzymes in Detergency edited by Jan H. Van Ee„ Onno Misset and Erik J. Baas (1997 Marcel Dekker, New York). The mechanism of the cleaning cellulase enzyme Celluclean™ from Novozymes (Bagvaerd, Denmark) is discussed in J Surfact. Deterg. (2012) 15:131-137 by A. Calvimontes; N. J. Lant; V. Dutschk.

WO 91/19794 discloses a method of increasing the effect of a polysaccharide hydrolase, characterized by incorporating a compound of the general formula:

R - O - (CH2 CH2 0)_n H whereby R is an aliphatic alkyl or alkyl-phenyl with 12-20 carbon atoms, and n is 10-100 into the reaction system in dissolved form.

There is a need to improve the performance of cleaning cellulose enzymes in detergent formulations. Summarv of the Invention

We have found that the combination of a cleaning cellulase and an alkoxylated polyaryl or polyalkyl phenol gives enhanced cleaning.

In one aspect the present invention provides a laundry detergent composition comprising:

(i) charged surfactant, preferably the level of charged surfactant is from 4 to 50 wt%, more preferably 6 to 30 wt%, most preferably 8 to 20 wt%;

(ii) alkoxylated polyaryl or alkoxylated polyalkyl phenol, of the following structure:

wherein Ri , is selected from linear or branched C3-C15 alkyl groups and aryl groups; X is selected from ethoxy or propoxy groups; n is from 2 to 70; T is selected from H , SO3; COO^" and PO3^2", preferably H and SO3^", preferably at a level from 0.1 to 20 wt%, more preferably 0.5 to 10 wt%, most preferably 2 to 9 wt%; and, a cleaning cellulase at a level of from 0.00005 to 0.5 wt % of pure enzyme, preferably 0.001 to 0.1 wt%.

Experimental Examples

A powder laundry detergent was prepared of the following formulation:

The formulation was used to wash eight 5x5cm knitted cotton cloth pieces in a tergotometer set at 200rpm. A 20 minute wash was conducted in 800ml of 13° French Hard water at 35°C, with 2.0g/L of the formulation. To simulate particulate soil 0.04g/L of 100% compressed carbon black carbon black (ex Sigma-Aldrich ) was added to the wash liquor.

Once the wash had been completed the cotton monitors were rinsed twice in 500ml clean water, removed dried and the colour measured on a reflectometer and expressed as the CIE L^*a^*b^* values. The colour difference between the monitors washed with carbob black and clean white cotton monitors, ΔΕ, was calculated using the following equation:

ΔΕ= [(Lc-Ls)² +(a_c-a_s)²+(bc-bs)²]^a5

Where L_c, a_c and b_c are the CIE L^*a^*b^* values of the clean white cotton monitor and L_s, a_s and b_s are the CIE L^*a^*b^* values of the monitors washed with carbon black.

Formulations were tested containing varying levels of Celluclean™ (Novozymes) a cleaning cellulase. Formulation were tested containing varying levels of the Celluclean.

The results are summarised in the table below. The 95% confidence limits are also given calculated from the standard deviation on the measurements from the 8 monitors. The L^* value is the mean of the measurements from the 8 monitors.

The cleaning cellulase, Celluclean™, reduces the deposition of the carbon black to the cotton cloth in a dose dependent manner, as observed by the ΔΕ values. Lower ΔΕ value indicates the cloth is closer to the original white. The cleaning effect of the enzyme saturates, so that no further significant benefit is observed above 40ppm.

The experiments at 10 and 20ppm was repeated with the addition of an alkoxylated polyarylphenol : polyethylene glycol mono(2,4,6-tris(1-phenylethyl)phenyl) ether with an average of 16 ethoxylate groups. (Emulsogen™ TS160 ex Clariant) and the results given in the table below.

Surprisingly addition of the Emulsogen TS160 increases the cleaning beyond that of the enzyme alone, even at the highest enzyme level tested. Thus 10ppm Celluclean™ and 100ppm Emulsogen™ has a lower ΔΕ (6.5) than 10ppm Celluclean™ alone (9.5) or 80ppm Celluclean™ alone (7.6).
