Long-form detergent review
Experienced members of our community test detergents with cloth nappies and general laundry.
Excellent option for soft water. All varieties except OMO Sensitive contain enzymes and wash well at 40ÂșC.
OMO/ Persil are the flagship products of CPG multinational Unilever. Our 2025 State of laundry survey showed that almost half (45%) of Australasian members use at least one product in the range.
Almost all products perform well at 40ÂșC, although enzyme-free products like Sensitive benefit from 60ÂșC washes for enhanced stain removal. The Ultimate range performs slightly better on stubborn stains.

Product varieties
Unilever lists detergent ingredients on its website; we cross-compared the product line and found that most of the range shares a consistent chemical foundation. In these cases, the individual products may still differ, with the exact formula containing different proprietary ratios, fragrances or colourants.
The primary differences come down to the inclusion of optical brighteners, specific scent profiles, and extra stain-removal boosters (such as sodium carbonate peroxide and TAED found in Ultimate powder).

Long-form review: OMO Ultimate Sensitive Liquid Front & Top (Anastasia)
I’ve been reading more about the differences between sensitive, “eco” and mainstream detergents, and wanted to test a new sensitive option.
This is an excellent detergent, especially if you want to avoid fragrances. It washes very well at 60ÂșC degrees and it washes well at 40ÂșC.
I used a lot of detergent because I have harder water and everything in my house seems to get filthy. I also used laundry booster in both the first wash and main wash cycles.
How do I know when to add more detergent? I check the wash cycle about 30-45 minutes in, and add more until I see a decent level of suds. Adding more detergent (when needed) during the cycle ensures everything comes out clean, smell and stain-free.
When you open the bottle it stinks! Not like fragrance, but like raw surfactant. I remember this smell from my days making cosmetics, they smell horrible. But it doesn’t matter, because there’s no smell left whatsoever on your laundry. Win!
Advantages
- Low fragrance.
- Performs well.
- Good for soft water areas (because it is a liquid).
Disadvantages
The liquid stinks! However, items do not smell after washing.
You need to use a lot if you have filthy laundry or harder water. If you have filthy laundry and harder water you’ll need to use significant amounts. This means it would be a costly detergent.
