Definitions

  • the present invention relates generally to bathing compositions. More specifically, the present invention provides a rinse-free bathing composition that exhibits excellent cleansing activity, while being devoid of alcoholic solvents.
  • Bathing forms an essential part of daily routine for cleansing the body and removing dirt and germs. Bathing soaps and body baths are widely used worldwide for this purpose. Bathing compositions can broadly be classified into two types: bathing compositions that require rinsing with water (also known as“wet body baths”) to remove the lather along with dirt and rinse-free bathing compositions that do not require rinsing but generally wiped with a soft cloth.
  • wet body baths are quite efficient, while they require the use of water, which is not feasible for several sections of persons like those who are bed-ridden or hospitalized. Further, wet body baths compositions generally contain alcohol and other harsh chemicals, which can cause skin dryness and are as such harmful.
  • Rinse-free compositions are a great way to reduce or preclude use of water in cleansing the skin and other body parts. Since no water is required, rinse-free bathing compositions can be used even by people living in areas where water is scarce, including campers, backpackers, defence personnel in remote areas, and the like. These are also very useful in hospitals for providing a warm, comfortable patient-friendly bathing or sponging alternative (especially useful for bedridden patients).
  • An object of the present disclosure is to provide a rinse-free bathing composition that satisfies the existing needs, as well as emerging ones, and generally overcomes the deficiencies found in the prior art.
  • Another object of the present disclosure is to provide a rinse-free bathing composition that is free from alcoholic solvents.

Abstract

La présente invention concerne une composition de bain sans rinçage qui présente une excellente activité de nettoyage sur les surfaces corporelles, tout en étant dépourvue de solvants alcooliques. La présente invention est basée, au moins en partie, sur le principe de découverte inattendue qu'une composition de bain comprenant une combinaison de tensioactifs comprenant une quantité efficace de cocamidopropyl bétaïne et de capryl glucoside présente une activité synergique, la combinaison présentant un indice de moussage étonnamment faible par rapport à son utilisation individuelle sans compromettre l'efficacité globale de nettoyage de la composition. En conséquence, selon un aspect de la présente invention, une composition de bain sans rinçage comprenant une combinaison de tensioactifs synergiques comprenant de la cocamidopropyl bétaïne en une quantité allant de 1,3 % à 1,9 % en poids de la composition et du capryl glucoside en une quantité allant de 1,3 % à 1,8 % en poids de la composition.
