Definitions

  • the present invention provides a new composition, in gel form, to be applied to the skin of individuals subjected to skin affections, as acne, pimples and blackheads, caused due to excessive oiliness of the sebaceous secreting glands, with the aim of reducing skin oiliness, maintaining it balanced in relation to cutis optimizing conditions.

  • the Hawthorn extract is also a vegetable extract, being rich in organic acids and natural antioxidants, flavonoids and procyanides, which have a significant action in skin lesions reduction, caused by inflammations and acne.
  • This extract is capable of reducing the Propionibacte um acnes population. Great quantities of this microorganism can be found in the skin subjected to acne affections. This extract collaborates to the inflammatory process reduction and, in association to salicylic acid, mitigates the hyperkeratinization.
  • This oiliness regulating agents association corresponds to composition's 10,00 to 50,00%, by weight.

  • Cytobiol iris extract is a product extracted from Iris germanica, a complex containing zinc and vitamin A in hydrosoluble forms, having proved favorable action in the bacteriostatic and anti-inflammatory (in case of acne) actuation area and sebaceous secretion regulation.
  • the above listed active substances are formulated in the form of an aqueous gel through usual processing techniques, and can be processed at room temperature, with adjunction of adequate additives, also known by themselves.

  • An antioxidant agent to avoid the deterioration of the substances sensible to the oxygen contained in the air, contributing for composition's chemical stability. This antioxidant is chosen between butyl hydroxytoluene (BHT), butyl hydroxyanisole (BHA), di-alpha-tocopherol and ascorbic acid, added in a ratio varying between 0,01 to 0,10%, by weight, in relation to the basis.

Abstract

La présente invention concerne un gel fluide, antiseptique, à action kératolitique pour les soins de la peau et procurant une sensation de fraîcheur agréable lors de son application sur la peau. Ledit gel est constitué d'un ensemble de nouvelles substances actives, chacune d'elle agissant de manière spécifique, à savoir : un agent régénérant, l'allantoïne, un agent humectant, le PCA de sodium, un agent restaurateur dermique, l'extrait d'Aloe vera, un agent kératolitique, l'acide salicylique, un agent antiseptique, le triclosan, deux agents de régulation séborrhéique de la peau, l'extrait d'aubépine et l'extrait de Cytobiol iris. Tous ces éléments coopèrent pour la régulation séborrhéique de la peau, en empêchant les excès de sécrétion et/ou l'obstruction des glandes sébacées ou des follicules, évitant ainsi les irritations de la peau. On prépare ces substances actives au moyen d'additifs classiques qui sont dissous et/ou dispersés dans un excipient aqueux, épaissis selon les techniques habituelles pour former un gel de consistance et de stabilité adéquates. L'usage dudit gel est particulièrement recommandé dans la composition d'un savon liquide antiseptique qui fait l'objet d'une requête séparée du même déposant.
