Definitions

  • Disinfecting composition for topical use is a composition for topical use
  • the present invention relates to compositions for topical use, preferably used for hygienic disinfection and for disinfecting washing of the hands, mucous membranes, damaged parts of the skin.
  • the present invention finds application in the cosmetic and dermocosmetic, dermopharmaceutical and human and veterinary pharmaceutical fields.
  • the objective of hand disinfection, hand decontamination and more generally skin antisepsis is to prevent the transmission of microorganisms and viruses or to suppress their unwanted introduction into threatened and / or injured areas of the body or more sensitive areas.
  • the compositions for hygienic disinfection and for disinfecting washing of hands and sensitive skin parts must meet efficiency requirements, some of which are defined by standards. Different methods are possible for treating the hands after contamination.
  • compositions for topical use for disinfecting washing and hygienic hand disinfection must be effective after having acted for short periods (for example 30 seconds or 1 minute). For toxicological reasons, it is also necessary, in addition to adequate efficacy, in particular compatibility with human skin.
  • compositions include as biocidal agents, for example short chain alcohols and excipients, regreasing agents, moisturizers and perfumes to improve the compatibility and acceptance of the skin.
  • the known compositions often also include additional agents such as biguanides (for example chlorhexidine), quaternary ammonium compounds (for example benzalkonium chloride), phenolic derivatives (for example orthophenylphenol) or carboxylic acids.
  • additional agents such as biguanides (for example chlorhexidine), quaternary ammonium compounds (for example benzalkonium chloride), phenolic derivatives (for example orthophenylphenol) or carboxylic acids.
  • biguanides for example chlorhexidine
  • quaternary ammonium compounds for example benzalkonium chloride
  • phenolic derivatives for example orthophenylphenol
  • formulations for topical foaming and disinfecting use require rapid foaming when applied to the part of the body to be disinfected.
  • the formation of foam constitutes one of the proofs of the effectiveness of the application and of the disinfection.
  • the speed of foam formation (or expansion time), the volume of this foam, its stability, as well as the pleasant sensations it induces, are important parameters to take into account to hope for the commercial success of these formulations.
  • Formulations for topical foaming and disinfecting use include foaming surfactants, whether of a cationic, anionic, amphoteric or nonionic nature. These surfactants are called amphiphilic because they consist of a hydrophilic part (or polar head), soluble in water, and by a lipophilic part (hydrophobic tail) which has an affinity with oils and fats. This amphiphilic structure makes it possible both to dissolve greasy dirt and to remove it by a washing operation.
  • Anionic surfactants are historically the surfactants which have been used to prepare foaming formulations for topical use.
  • Sulphated anionic surfactants are a class of surfactants frequently used because of their good foaming properties. These surfactants to produce an aerated foam whose feel is not considered unpleasant by the consumer.
  • these surfactants have the drawback of being sensitive to the degree of hardness of the water and to the presence of greasy dirt, which consequently results in a reduction in the volume of foam initially generated by these formulations but above all in a reduction in the stability over time of this volume of foam.
  • foam stabilizing additives are often not very biodegradable and sometimes toxic, which makes them non-compliant with the new environmental requirements and regulations, and for application to the skin.
  • compositions based on a sodium salt of cocoyl glutamate and mixtures of alkylpolyglucosides Cl 2- 16, and / or alkylpolyglucosides in which the alkyl chain carries from 4 to 7 carbon atoms do not allow to produce stable foam after addition of disinfecting agent.
