SCA Hygiene Products AB (Gothenburg, Sweden) has patented a hygiene
tissue is used for both cleaning and transferring lactic acid producing
bacteria to the skin and urogenital area. The hygiene tissue contains,
on separate parts of the tissue, cleaning liquid and a bacterial
composition. Bacterial viability and transfer ability is maintained by
suspending the bacteria in a lipid which protects the bacteria from
moisture. The lipid also enhances transfer of the bacteria from the
tissue to the skin or urogenital area. Different designs of the hygiene
tissue prevent the mixing of the cleaning liquid and the bacterial
composition. (US 7,482,023)
