Hello Yolibolli, thank you for your inquiry. We have of course discussed your request with the relevant department. We are happy to provide you with the following information: By switching from "Migros Plus" to "Nature Clean", we have set ourselves the goal of making an important contribution to sustainability. The products from the "Nature Clean" line are characterized by a very high biodegradability of between 96% and 100%, which has a positive impact on the environment. We have also succeeded in increasing the proportion of recycled plastic in the packaging. In addition to these aspects, we have also revised the composition. The products are now free from preservatives, microplastics and perfume. This has led to an increase in raw material costs, which explains the price increase. However, the formulas are now more concentrated than those of the predecessors, which means that the dosage is more economical. In concrete terms, this means that you can use the contents of an item for longer. We hope that our answer will be helpful to you. Best regards, Lea
