Definitions

  • the invention relates to a multi-phase cleaner in which a droplet-shaped apolar component is incorporated so that a homogeneous distribution of the ingredients is ensured during use, preferably by spraying.
  • Sprayable cleaners are usually liquid or gel-like. Usually water, occasionally another polar solvent, forms the basis of the formulation.
  • the incorporation of non-polar additives therefore poses a problem for the person skilled in the art, particularly with a low surfactant content, the homogeneous distribution in the system is not always guaranteed.
  • a low surfactant content is desirable since high amounts of surfactant are not required in ready-to-use, that is to say undiluted, agents and can leave streaks when used as cleaning agents, and they also cause higher production costs.
  • a corresponding product must be available in a visually appealing form that is easy to handle by the consumer.
  • the incorporation of the hydrophobic phase as droplets and / or particles and / or bubbles is desirable.
  • these droplets or particles can float or sediment due to the difference in density, and on the other hand they can coagulate into a uniform phase.
  • Products are known from the prior art (e.g. WO 99/47635) and from the market, which the consumer has to shake before use in order to obtain a temporary emulsion. It must be ensured that a sufficient amount of active ingredient is applied to the surface to be cleaned even after very short or weak shaking. This makes handling difficult, especially with sprayable cleaners. It is therefore desirable to obtain a cleaner, in particular a sprayable cleaner, which keeps such droplets or particles in suspension due to its internal structure.
  • the application WO 96/37594 presents a multi-phase personal cleanser in which two oily components of different interfacial tension are dispersed.
  • the oil droplets have a maximum diameter of 30 ⁇ m and are kept stable there by the addition of clays and gums to the aqueous phase.
  • the use of such an agent for cleaning hard surfaces is just as little described as the possibility of spraying the agent.
  • Japanese publication JP 11 246348 A2 describes a multi-phase agent for cleaning the facial skin and for removing makeup.
  • An aqueous, surfactant-containing system is emulsified with an oil, so that the two phases originally present can no longer be distinguished by the consumer. Neither the cleaning of hard surfaces nor the spraying of the agent is described here.
  • European patent EP 490 749 B1 finally describes an agent in which an oil phase in the form of microspheres is present in an aqueous, surfactant-containing phase.
  • the microspheres sink to the bottom; by shaking, they are temporarily suspended in the aqueous phase.
  • the oil phase consists largely of dialkyl phthalates. Again, it is a cosmetic product that is neither intended for cleaning hard surfaces nor for spraying.
  • the object of the present invention is therefore to provide a preferably sprayable multiphase cleaner which combines the advantages of a cleaner with hydrophobic components and is thereby obtained in an optically appealing form which is easier for the consumer to handle, and which can be used directly, so that the disadvantages described are not occur more.
  • the aqueous phase of a multiphase cleaner for example by adding a thickener, can be given an internal structure through which a gaseous, solid or liquid phase in the form of bubbles and / or particles and / or droplets in suspension can be held.
  • a gaseous, solid or liquid phase in the form of bubbles and / or particles and / or droplets in suspension can be held.
  • the invention accordingly consists of a preferably sprayable, multi-phase cleaner which keeps a discontinuous gaseous and / or a discontinuous solid and / or a discontinuous liquid hydrophobic phase in suspension due to the internal structure of the continuous aqueous phase.
  • a further subject of the invention is a product which contains an agent according to the invention and a spray dispenser.
  • a third subject of the invention is the use of an agent according to the invention for cleaning hard surfaces, in particular glass, and as a pretreatment and cleaning agent for textiles.
  • a fourth subject of the invention is a method for cleaning and / or maintaining hard surfaces, in which the agent according to the invention, preferably by spraying, is applied to the surface to be cleaned and / or cared for and is wiped over the surface with an absorbent soft object to develop the cleaning effect.
  • a fifth subject of the invention is a process for cleaning and / or maintaining textile surfaces and for pretreating textiles, in which the agent according to the invention is applied, preferably by spraying, to the surface to be cleaned and, if appropriate after a contact time, by washing, suctioning or dabbing or wiping with a damp cloth or sponge.
  • the sixth object of the invention is a process for the preparation of the agent according to the invention, in which an outer aqueous phase with an inner structure is first produced, then an inner oil-containing phase is produced and this is then dispersed in the aqueous phase.
  • the aqueous phase preferably contains one or more thickeners to produce an internal structure.

Abstract

L'invention concerne des agents aqueux, sous forme de gels, multiphases, renfermant des tensio-actifs, contenant au moins une phase aqueuse (I) et une phase hydrophobe (II), non miscible avec cette phase aqueuse, la phase hydrophobe étant maintenue en suspension, sous forme de bulles et/ou de particules et/ou de gouttelettes, dans la phase aqueuse. Les agents précités sont utilisés, éventuellement sous forme d'un produit renfermant un véhiculeur de pulvérisation, pour le nettoyage de surfaces dures ou de surfaces textiles, en pulvérisant l'agent, sans l'agiter au préalable, sur la surface à nettoyer ou en l'appliquant d'une toute autre façon au moyen d'un réservoir. L'agent nettoyant selon l'invention est fabriqué en créant une structure interne dans une phase aqueuse extérieure et en dispersant dans celle-ci, la phase hydrophobe interne, après sa production, de telle façon que les bulles et/ou particules et/ou gouttelettes soient détectables, au moins en partie, à l'oeil nu.
