LAUNDRY DETERGENT COMPOSITION

Abstract

A concentrated laundry composition premix which is dilutable in water to form a laundry liquid composition, said premix comprising at least 20% wt. water, from 0.1 to 8% wt. ethoxylated sorbitan di- or tri-ester, and comprising from 10 to 40% wt. surfactant active excluding the ethoxylated sorbitan di-or tri-ester.

Claims

1. A concentrated laundry composition premix which is dilutable in water to form a laundry liquid composition, said premix comprising at least 20% wt. water, from 0.1 to 8% wt. ethoxylated sorbitan di- or tri-ester, and comprising from 10 to 40% wt. surfactant active excluding the ethoxylated sorbitan di-or tri-ester.

2. A concentrated laundry composition premix according to claim 1 wherein the premix comprises from 0 to 5% wt. alkyl ether sulphate.

3. A premix according to claim 1 or 2 wherein the surfactant comprises anionic surfactant and non-ionic surfactant in a weight ratio of from 50:50 to 1:99 and wherein the composition comprises from 0 to 5% wt. alkyl ether sulphate.

4. Premix composition according to claim 1 comprising a hydrotrope.

5. Premix composition according to claim 1 having a viscosity measured at 21° C. and 106 s.sup.−1 of from 100 to 800 mPa.Math.s.

6. Premix composition according to claim 1 wherein the composition comprises from 0 to 1% wt. the total surfactant alkyl ether sulphate.

7. A method for forming a laundry detergent composition by diluting one part premix as claimed in claim 1 from 1 to 10 parts water.

8. A container comprising a premix as claimed in claim 1.

9. A container according to claim 8 wherein the container displaces a volume appropriate to permit dilution of said premix to form a liquid detergent composition at an appropriate dilution.

10. A kit comprising a container as claimed in claim 8 in combination with a further keeper container.

Example 2

[0175] The following is an embodiment process.

[0176] Make a pre-mix of optical brighter, water, dye. Separately, prepare a batch of brine, water, MPG, glycerin, TEA, NaOH (60% of total formula quantity).

[0177] Then add LAS acid and allow to react for 5 minutes.

[0178] Add the remaining (about 40%) of the NaOH to adjust pH for 6.5-7.5 (preferably 6.5 to 7.0).

[0179] Add Betaine (55° C.) before adding the non-ionic surfactant and maintaining the temperature of the batch at 45° C.-55° C. Mix for 5 min.

[0180] Add pre-heated ethoxylated sorbitan ester and maintain batch temperature at from 45° C.-55° C.

[0181] Cool down to 30° C. by no more than 1° C. per minute.

[0182] At 40° C. add preservatives.

[0183] Add the premix of optical brighter and dye.

[0184] At 30° C. add enzymes.
