Definitions

  • the invention relates to a new category of ecobiological cosmetic topical products comprising alcohol at a defined dose to be endowed with virucidal, bactericidal and yeasticidal activities and a lipid substrate at a defined dose to preserve and promote the lipid film of the skin, thus making it possible to maintain its properties in terms of its barrier effect and its hydration.

  • the hands are cleaned in particular with washing compositions, washing gels or else by friction with hydro-alcoholic solutions or gels.
  • biocides are particularly aggressive for the skin and for the skin microbiome, that is to say the community of microorganisms that make up the skin flora. Biocides are therefore the cause of side effects such as intolerance, allergies or skin lesions which have been frequently noted by health professionals; their use is generally limited.
  • the skin is the first protective barrier against external aggressions (pathogens, contamination, chemical attacks, etc.). Through its barrier function, the skin plays a protective role against external stress factors and also prevents the evaporation of water. Regularly attacked by these cleansing compositions, the skin can lose its natural defense and protection capacities over time. Repeated multi-daily washes have an undeniable effect on the skin ecosystem by eliminating the lipids which naturally preserve and protect the skin.

  • the measurements of the bactericidal, virucidal, yeasticidal, barrier and tolerance effects are carried out by following the protocols described in Example 1 of the invention.
  • Example 3 in particular Examples 3B to 3E, are therefore capable of exerting all the expected effects, unlike the hydroalcoholic solutions currently marketed.
  • the measurements of the bactericidal, virucidal, yeasticidal, barrier and tolerance effects are carried out by following the protocols described in Example 1 of the invention.
  • Example 4 in particular Examples 4B to 4F are therefore capable of exerting all the expected effects, unlike the hydroalcoholic solutions currently marketed.
  • Example 5 Cosmetic compositions of lipoalcoholic gel type
  • the measurements of the bactericidal, virucidal, yeasticidal, barrier and tolerance effects are carried out by following the protocols described in Example 1 of the invention.
  • Example 5 The formulations of Example 5 are therefore capable of exerting all the expected effects, unlike the hydroalcoholic solutions commonly marketed.
  • Example 6 Cosmetic compositions of lipoalcoholic emulsion type
  • the measurements of the bactericidal, virucidal, yeasticidal, barrier and tolerance effects are carried out by following the protocols described in Example 1 of the invention.
  • Example 6 The formulations of Example 6 are therefore capable of exerting all the expected effects, unlike the hydroalcoholic solutions currently marketed.
  • Example 7 Comparative cosmetic compositions according to the invention The ingredients are identified according to the INCI nomenclature and the percentages are given by weight / weight in tables 13 and 14. T corresponds to a formulation of the composition according to the invention and the formulations 7A to 7N are formulations of the prior art.
  • the measurements of the bactericidal, virucidal, yeasticidal, barrier and tolerance effects are carried out by following the protocols described in Example 1 of the invention.
  • Example 7 (7A to 7N) are therefore not capable of exerting all the expected effects of the invention, unlike the control T which corresponds to a formulation of the composition according to invention.
  • Strong to very strong intolerance problems have been demonstrated after only a few days of multiple daily applications, in particular with the use of essential oils, perfumes, pH adjusters, bactericides, and more. more surprising with emulsifiers derived from silicone and foaming surfactants.
