Frosch is a trademark for cleaning and care agents made by the Mainz-based company Werner & Mertz GmbH.

By launching Frosch, the company complemented its current product portfolio (including Erdal) by adding a brand with a clear focus on ecological aspects in addition to efficiency.

[3] Werner & Mertz registered the "Frosch neutral soap cleaner" in April 1986 as the first phosphate-free household cleaning agent.

In her 1998 work "Bedeutung und Analyse einer umweltorientierten Kommunikationspolitik", Kerstin Haas writes that Frosch products were developed to be both environmentally sustainable and efficient at cleaning.

[16] Like the products by other manufacturers, Frosch cleaning agents continue to use surfactants acquired from palm kernel oil.

This practice is criticised, as the cultivation of suitable plantations requires deforestation, especially of tropical rainforests in South-East Asia.

[19][20] Werner & Mertz uses the "Frosch Initiative" to pool its sustainability efforts to increase the plastic recycling quota and use of European vegetable oils.

[22] Professor of marketing Franz-Rudolf Esch states that Frosch is a successful brand for green cleaning agents.

[23] Kerstin Haas argues that the Frosch brand stands for "innovation and competence in the market of environmentally friendly cleaning products".

[24] According to professor of marketing Marcus Stumpf, Frosch is the "best-known and most popular organic cleaing products brand".

[9] Most recently, it took first place in the household cleaner category of the Trusted Brands 2020 market study by Reader's Digest.

Most recently, Frosch Senses Orange Blossom Sensitive Shower Gel was awarded 2020 Product of the Year in gold.

[36] Since 2014, Frosch has been making its PET packaging from post-consumer recyclate, 20 per cent of which was obtained from yellow sack waste.

The Frosch Universal detergent was marked down due to the dye transfer inhibitor it contains, which Ökotest counts as a synthetic polymer.
