LAUNDRY DETERGENT COMPOSITION

Abstract

A concentrated liquid laundry detergent composition premix having a viscosity measure at 21° C. 106 s-.sup.1 of from 100 to 800 mPa.Math.s. and which is dilutable in water to form a stable laundry liquid composition, said premix comprising from 20% wt. water, from 14-20% wt. hydrotrope, from 20 to 70% wt. surfactant, and wherein the surfactant comprises anionic surfactant and non-ionic surfactant in a weight ratio of from 1:1 to 1:99 and wherein the composition comprises from 0 to 5% wt. alkyl ether sulphate. Method of forming a laundry detergent composition by diluting one part premix in from 1 to 10 parts water. Container comprising the premix. Kit comprising the container in combination with a further keeper container.

Claims

Example 2

[0220] The following is an embodiment process.

[0221] 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).

[0222] Then add LAS acid and allow to react for 5 minutes.

[0223] Add the remaining (about 40%) of the NaOH to adjust pH for 6.5-7.5 (preferably 6.5 to 7.0).

[0224] 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.

[0225] Add pre-heated ethoxylated sorbitan ester and maintain batch temperature at from 45° C.-55° C.

[0226] Cool down to 30° C. by no more than 1° C. per minute.

[0227] At 40° C. add preservatives.

[0228] Add the premix of optical brighter and dye.

[0229] At 30° C. add enzymes.
