As usual, Sonett is the option for not-quite-so-environmentally-unfriendly as other brands in the category. Laundry liquid is based on plant extracted chemicals with soap making up most of it. The ingredients are 100 % biodegradable and the fragrant come from natural plant oils, which usually aren't a problem for the allergic.

Attention! Due to the high olive oil content, the product will become a bit more solid and cloudy at temperatures below 10 °C. This is supposed to happen and things will normalize when the product gets back to room temperature.
The temperature range is 30 - 40 °C and this is suitable for both manual and machine washing. For 4,5 kg washing machine and soft water (like most of Finland), use 60 ml, for hard water conditions (like Lohja and other places, not Finland), use 90 ml. In soft water conditions, you get about 17 uses per bottle for 0,82 € per washing.
