- An aqueous liquid laundry detergent was prepared of the following formulation:
- the surfactants other than AEC were linear alkyl benzene sulfonate (LAS), sodium lauryl ether sulfate (SLES) with 3 moles of ethoxylation and a non-ionic (Nl) a C12-C15 linear alcohol alcohol with 7 moles of ethoxylation.
- the level of surfactant given in the table is the sum of LAS, SLES and Nl.

- Formulations were made with and without the addition of 4 wt.% of Alkyl Ether Carboxylate (AEC).
- the AEC used had 10 moles of ethoxylation and an oleyl alkyl chain.
- the formulation was used to wash eight 5 x 5cm EMPA 1 17 stain monitor (blood/milk/ink stain on polycotton) in a tergotometer set at 200rpm. A 60 minute wash was conducted in 800ml of 26° French Hard water at room temperature (293K), with 2.3g/L of the formulation. To simulate oily soil (7.5 g) of an SBL2004 soil strip (ex Warwick Equest) cut into 4 equal pieces was added to the wash liquor.
- the cotton monitors were rinsed once in 400ml clean water, removed, dried and the colour measured on a reflectometer and expressed as the R460, which is the % reflectance at 460nm (UV excluded).
- AR460 L(AEC) - ..(control without AEC)
- the comparative example A is considered to fairly reflect the disclosure of the prior art WO 2016/180552 (example 1 ) and DE 10 2013 218 614A (example B) which disclose exemplar formulations having LAS:NI:SLES in weight ratios of 4:1 :5 (WO 2016/180552) and 4:2:5 (DE 10 2013 218 614A).
- inventive formulations with high proportion of LAS relative to the other surfactants showed a much greater benefit from the addition of the AEC in comparison to the formulations with much lower proportions of LAS.
