2X-Ultra Concentrate Laundry
New to the market is a range of products labelled as 2X concentrates and 2X Ultra concentrates. These are not the first of the highly concentrated products as we tested four in our recent 2009 analysis of 71 samples. What is new is that the major manufacturers (Colgate-Palmolive Pty Ltd, Unilever Australasia, United Laboratories Pty Ltd and PZ-Cussons) seem to have taken a major step to reduce the volume of detergent required for a "normal" wash (whatever "normal" is supposed to mean). If the dose of these 2Xultra products is to be taken as the norm for ultra-concentrates, then other manufacturers were doing this for several years. For the last batch (2009), 22 of 42 front loader samples had doses less than 65 g, and 13 of 47 top loaders fell into this category.
We purchased 16 products from Coles Supermarket in Armidale NSW on 16th March 2009 and analysed these products (7 front loader and 9 top loader) during the same week. The results are shown below, all on this one page without any reference to the interpretation of the constituents. We will not be repeating information that is available on other pages of this website. So to see the implication of sodium on greywater, you need to read the pages on Sodium, Greywater and Gardens.
What we bought.
Packet sizes varied from 0.5 kg, 0.65 kg to 1 kg.
Each pack came with a scoop that varied from 58 mL to 72 mL. These scoops are smaller than the scoops in the normal concentrates for these products.
When converted from volume to mass (required to calculate the number of washes per kilogram), the scoops varied from the smallest at 42 g to the largest at 65 g.
Moisture of each sample from a freshly opened pack of detergent varied from 1.05% to 13.7%.
Salinity - as measured by
electrical conductivity (wash water only)
pH (measure of the
acidity or alkalinity of the wash water - pH 7 is neutral, <7 is acid, >7
