Essences, aromas and essential oils

It was 1945 when Carlo Pezzi, a renowned Italian perfumer, founded Muller & Koster in Geneva, a company specializing in the production of fragrances and the creation of high-quality scented essences for cosmetics.

Today, the third generation of the family creates fragrances, essential oils and aromas for a wide range of cosmetics and cleansing products for personal care, as well as for home cleaning and health & hygiene.
