Definitions
- TITLE Product comprising a fibrous support and a benefit agent
- the invention relates to a product comprising a fibrous support and a benefit agent.
- the product can provide benefits such as preventing bacteria proliferation.
- the invention also relates to a process of treating a surface for example against bacteria proliferation, comprising the step of applying onto the surface a product according to the invention. This can provide cleaning, disinfection, suppression of odors, and/or prevention of malodors.
- WO02085109 disinfection of hard surfaces in the house with thymol, geraniol, carvacrol, citral, terpinene, carvone, limonene.
- WO9802044 describes the use of thymol, eugenol, verbenone, eucalyptol, terpineol, cinnamic acid in hard surfaces and laundry detergent formulations.
- natural ingredients mentioned above are not considered as completely safe, although they benefit from a great impact in consumers mind because they have a natural origin.
- Others essential oils are under scrutiny and the Directive European 2003/15/EC now limits the amount of some fragrances or oils in cosmetics and detergents in order to reduce the risk of skin irritation or sensitization that may occur by repeated exposure to these compounds.
- Limonene, geraniol, eugenol cinnamal and cinnamyl alcohol are amongst the essential oils that need to be incorporated at levels below 100 ppm for rinse off formulations and below 10 ppm for leave on formulations, in order to limit the risk of allergy and sensitization. These low amounts can limit the benefits thereof.

- Hop extracts such as hop acids (alpha acids also referred to as Humulone and Beta acids also referred to as Lupulone) present in Hop have been long known and used for their bacteriostatic and bacteriocidal functions in the beer industry.
- Hop acids include the alpha and beta acids and their GRAS derivatives traditionnaly used for the preparation of beer like: humulone, cohumulone, adhumulone, iso humulone, iso cohumulone, iso adhumulones, dishydro iso alpha acids, tetrahydro isoalpha acids, hexahydro iso alpha acids, hexahydrolupulone, hexahydrocolupulone ( hexahydro beta acids)...
- hop acids used alone or in blends
- hop compounds like iso alpha acids are weak acids that can cross cytoplasmic membranes and disrupt the pH gradient of the cell, which results in the starving of the cell. Examples of references about this topic include the following documents:
- Environmet.l Microbiol., 2002,68,11 , 5374-5378 Methods have been described to extract bacteriostatic agents from hop flower and use these extracts to neutralize resident gram + bacteria on skin, that when in contact with sweat will be responsible for the development of malodor.
- a method for producing a skin deodorant based on this bactericidal extract is described in document US 4,170,638.
- Beta acids from hop have been shown as demonstrating superior efficiency against development of gram + bacteria and claimed for use in food preservation. This is for example described in documents US 5,286,506 and US 6,475,537.
- Blends of hexahydrocolupulone and tetrahydroisohumulone have been described to inhibit listeria growth, in document US 5,455,038.
- hop extracts as herbal medicine has been long established by tradition and is now supported by current research. Hop extract is reported to have been used topically to treat sores and skin injuries. It is used in skin creams and lotions as a skin emollient (Hops, Presentation to Herbal Medicine Seminar, Canterbury College of Natural medicine, New Zealand July, 2001 ). There is a revived interest for hop properties in modern medicine as evidenced by the recent scientific publications dealing with applications of its relaxant and bacteriostatic properties. Relevant references include the following: - Pharmacodynamic study of the lupulus' tranquilizing action. Boll Chim. Farm 1974.

- the product can provide disinfecting as well as odor and/or malodor control benefits, while trying to prevent any risk of sensitization by skin contact/ inhalation, during the cleaning step to remove source of malodor and/or while the consumer wears the clothes to neutralize the gram + bacteria that can be present on skin and are responsible for the malodor generation.
- This is true for the detergent used to clean clothes in the home as well as for the detergents used to clean linen and clothes, carpets and upholstery in collectivities such as schools, restaurants, hotels, hospitals, elderly homes where the risk of contamination by gram + bacteria is even greater.
- This operation of disinfecting clothes and/or preventing malodor generation due to resident bacteria on skin can be done without being detrimental to the skin and without risking to generate irritation and sensitization through skin contact and inhalation.
- the product can provide bacteriostatic, bactericidal and/or malodor treatment to surfaces in the home, like those that are susceptible to be contaminated by gram + bacteria, while diminishing the risks of sensitization of the consumer by skin contact and/or inhalation.
- the product can provide bacteriostatic, bactericidal and/or malodor treatment, while preventing any risk of sensitization by skin contact and/or inhalation.
- the product can provide bacteriostatic , bactericidal and/or malodor treatment to surfaces while trying to prevent any risk of sensitization by skin contact and/or inhalation.

- the most prevalent groups of bitter acids found as components of hops are the alpha-acids and the beta-acids, also referred to as humulones and lupulones, respectively. Both contribute bitterness to beer, but the alpha-acids are much more intense in this regard than the beta-acids.
- Producers of hop extracts isolate the alpha and beta acids commercially by various chromatographic techniques and have recently developed a technique to separate the two acid fractions using liquid carbon dioxide under supercritical conditions.
- a by-product of the operation is a product which contains approximately 61 weight percent beta-acids, the remainder consisting essentially of hops resins.
