  • Patent number: 8992901
    Abstract: The invention is in the field of skin hygiene, especially hand hygiene and/or hand soap compositions. It remains to be desired to prepare skin hygiene compositions having a high anti-microbial effect, even with a low dosage of anti-microbial essential oils. It is therefore an object of the invention to provide a skin hygiene composition, having good anti-microbial properties, at low levels of essential oil. Surprisingly it has been found that composition comprising a low amount of at least two essential oils and a polymer provides improved hygiene efficacy.
