Definitions

  • the present invention generally relates to emollient and sanitation compositions; and more particularly, representative embodiments of the present invention generally concern delivery of emollients in topically applied disinfectant formulations.
  • Antibiotic resistant strains of disease-causing bacteria such as Staphylococcus aureus
  • Staphylococcus aureus are now commonly acquired in hospital settings due to close contact of patients who are more susceptible to infection and the extensive use of antibiotics, which generally provide selection pressure for these strains of bacteria. Consequently, people infected with these microbes are likely to have longer hospital stays and may require treatment with second- and third- choice antibiotics that may be less effective and more expensive.
  • non-compliance with these policies has been reported to be between 45% and 70%.
  • a prominent reason cited for non-compliance is the incidence of acute and chronic irritated skin and, to a lesser extent, contact allergic hand dermatitis due to repeated use of antibacterial soaps and the use of alcohol-based (either ethanol or isopropanol, 60%- 95% wt/wt) hand sanitizers.
  • the use of these sanitizers can be as high as fifty or more times during each work day.
  • the chronic stripping of the lipid barrier usually results in xerosis, scaling, erythema, rough skin, and tight skin.
  • More serious and painful side effects include inflammation, fissures, allergic contact dermatitis, and the harboring of transient pathogenic organisms that may cause infections.
  • Common sensations associated with de-lipidization include itching, tingling, burning, stinging, and the like.
  • the present invention provides compositions and methods for providing botanically-sourced and/or botanically-derived topical emollient compositions with disinfectant properties to ameliorate dermatitic symptoms of mammalian integument.

Abstract

La présente invention concerne des compositions désinfectantes émollientes d'origine botanique et dérivés de composés botaniques pour une utilisation topique. Des compositions représentatives aident généralement à la reconstitution du profil lipidique du stratum corneum (310) en fournissant des lipides et/ou des dérivés de lipides d'origine botanique qui ressemblent au sébum humain - ces composants étant ordinairement réduits par l'utilisation de produits traditionnels désinfectants pour les mains. Les caractéristiques et spécifications décrites peuvent être diversement contrôlées, adaptées ou éventuellement modifiées pour réaliser, par exemple, des formulations désinfectantes pour les mains améliorées. Des modes de réalisation représentatifs de la présente invention concernent généralement des compositions anti-microbiennes mélangées avec des lipides et/ou des dérivés lipidiques d'origine botanique pour contrôler ou sinon améliorer les symptômes de dermatoses (par exemple, 320) associés à une utilisation fréquente de produits désinfectants pour les mains traditionnels.
