Persil Megaperls comes with oxy bleach and brighteners - no need to add extra oxy. Persil Megaperls Color has neither oxy nor brighteners but color transfer inhibitors. Perwool lacks enzymes so it's suitable for woolens.

- Persil Megaperls for load 1) and 3) - the oxy ingredients starts working at 104F (warm) but works even better at 140F (hot). Dust mites die at 140F and above.
- Persil Megaperls Color for load 2) and 4). It's certainly gentle enough for most cottons and blends and even has an enzyme in it to eat cotton fuzz/lint balls off your clothes.
- Perwool for load 5).

I always go by the dosing instructions on the package and never has sudsing issues or allergic reactions. By German definition (and I suppose Henkel goes by this one), soft water is below 8 gpg, medium is below 14 gpg and hard above 14 gpg.

The Persil Color liquid was just recently tested by our consumer magazine and, as usual, didn't clean quite as well as the powder.
