Definitions

  • the present invention relates to a sanitary article, such as an absorbent article or a hygiene tissue, comprising a delivery member for delivery of an additive to a user.
  • the additive contributes to the effect and function of the sanitary article and comprises one or more constituents which are of interest to deliver to the skin and/or the urogenital area of a user.
  • the urogenital area harbors a complex microbial ecosystem comprising more than 50 different bacterial species (Hill et al., Scand. J. Urol. Nephrol. 1984;86 (suppl.) 23-29).
  • the dominating species in this area for fertile women are lactic acid producing bacteria.
  • Examples of such bacteria include bacteria belonging to the genus Lactobacillus, Lactococcus, Bacillus and Bifidobacteria. These lactic acid producing members are important for retaining a healthy microbial flora in this area, and act as probiotic bacteria with an antagonistic effect against pathogenic microbial species.
  • Lactic acid producing bacteria inhibit growth and colonization by other microorganisms by occupying suitable niches for colonization, by forming biofilms and competing for available nutrients, thereby excluding colonization by harmful microorganisms. Also, the production of hydrogen peroxide, specific inhibiting substances, such as bacteriocines, and organic acids (including lactic acid and acetic acid) that lower the pH, inhibit colonization by other microorganisms.
  • the microbial ecosystem in the urogenital area of a healthy individual can be disturbed by the use of antibiotics, during hormonal changes, such as during pregnancy or use of contraceptives with estrogen, during menstruation, after menopause, in people suffering from diabetes etc. Also, microorganisms may spread from the anus to the urogenital area, thereby causing infections. This results in a disturbance of the normal microbial flora and leaves the individual susceptible to microbial infections that cause vaginitis, urinary tract infections and ordinary skin infections.
  • Microorganisms commonly associated with these kinds of infections belong to the genera Escherichia, Enterococcus, Psedomonas, Proteus, Klebsiella, Streptococcus, Staphylococcus, Gardnerella and Candida. Women are at particular risk due to their shorter distance between the anus and the urogenital tract; especially at risk are young women, who not yet have a well developed microflora in the urogenital area and older women, who no longer have a protective flora.
  • the balance is easily disturbed, whereby discomfort and smarting may result.
  • the balance may be disturbed by extensive cleaning, by the use of antibiotics or antifungal agents, by the use of absorbent articles that may dry out the skin and mucous membranes and/or by the above mentioned microbial ecosystem being disturbed.
  • the skin has a delicate balance of moisture, fat and microorganisms, which is easily disturbed by conditions that dry out the skin and that disturb the microbial balance, such as extensive cleaning.
  • infections in the urogenital area and the skin caused by undesirable microbial organisms have been treated by the administration of antibacterial and antifungal agents to the affected body part.
  • antibacterial and antifungal agents may be used to treat infections, they may also in themselves cause a disturbed microflora.
  • probiotic bacteria such as lactic acid producing bacteria
  • prebiotics may be interesting to deliver to the urogenital area or the skin in order to improve the milieu in these areas.
  • Prebiotics promote a balanced microflora when administered in adequate amounts to a host.
  • Examples of prebiotics are nutrition for probiotic bacteria, substances that promote adhesion to the host of probiotic bacteria and pH regulating substances.
  • pH regulating substances may be of interest to deliver to the skin and/or urogenital area in order to maintain and/or achieve a low pH for several other reasons.
  • cooling substances, anti-itching substances and aromatic substances may also be delivered to the skin and/or urogenital area for achieving increased comfort.
  • additives comprising a beneficial substance, composition or agent such as e.g. any of those mentioned above, in a sanitary article, such as a hygiene tissue or an absorbent article, and to deliver the additive to the skin and/or urogenital area of a user via the sanitary article.
  • a beneficial substance, composition or agent such as e.g. any of those mentioned above
  • additives comprising probiotic bacteria can be delivered to a user via absorbent articles, such as diapers, sanitary napkins, incontinence guards, panty liners and tampons, as described in, for example, WO 92/13577, WO 97/02846, WO 99/17813, WO 99/45099 and WO 00/35502. It has also been suggested to deliver additives comprising probiotic bacteria to a user via hygiene tissues, as disclosed in WO 04/060416.
  • an additive may be delivered to a user via a sanitary article in a confined area of the article such that it does not spread to other parts of the article before and/or during use.
  • a sticky additive may stick to the package or smear over the article in an undesired manner which makes the article look messy or which may impair its function, e.g. by reducing its liquid absorbing properties.
  • fatty acids and other hydrophobic substances may impair the liquid absorbent properties of absorbent articles and therefore need to be protected from being spread over the article during transport and storage.
  • it may be of interest to deliver an additive to a specific body area of a user of a sanitary article.
  • WO 2007/073263 and WO 2008/054268 disclose sanitary articles comprising one type of a delivery member for delivery of an additive to the skin and/or the urogenital area of a user.

  • Water activity a w measures the vapour pressure generated by the moisture present in a hygroscopic product.
  • Water activity reflects the active part of moisture content or the part which, under normal circumstances, can be exchanged between the product and its environment. Water activity is usually defined under static conditions of equilibrium. Under such conditions, the partial pressure of water vapour (p) at the surface of the product is equal to the partial pressure of water-vapour in the immediate environment of the product. Any exchange of moisture between the product and its environment is driven by a difference between these two partial pressures.

  • the second interior surface 15 is three-dimensionally structured according to the invention, the percentage of the additive 7 that is removed together with the first layer 8 or parts thereof upon removal in order to expose the additive 7 is reduced compared to the case when the second interior surface 15 is smooth. This is due to several reasons. However, above all this is due to the fact that the structuring implies that the contact surface of the second layer 9 with the additive 7 in the chamber 10 is increased compared to the case when the second interior surface 15 is smooth.
