Definitions

  • the invention relates to the use of polyethyleneimine for the absorption of odor-active substances.
  • polyethyleneimine is extremely suitable for forming stable absorption compounds with fatty acids, aldehydes and ketones and thus rendering them odorless.
  • the invention accordingly relates to the use of polyethyleneimine for the absorption of odor-active substances.
  • odor absorbent The most important requirements to be met by an odor absorbent are good effectiveness ibei lower Amount of use, value for money, odorlessness, toxicological harmlessness, compatibility with materials to be treated and biodegradability. These requirements are ideally met by polyethyleneimine.
  • Polyethyleneimine is made by polymerizing ethyleneimine.
  • the degree of polymerization of the polyethylene imine used according to the invention must be so high that the polyethyleneimine is toxicologically harmless. As the degree of polymerization increases, the water solubility of the polyethyleneimine decreases.
  • the degree of polymerization of the polyethyleneimine used according to the invention is not subject to any restrictions apart from the aforementioned minimum degree of polymerization, those polymeric ethyleneimines which still have sufficient water solubility are preferred for reasons of easier handling.
  • Such polyethyleneimines are commercially available and are known to the person skilled in the art with regard to their properties (cf. Ullmann's Encyclopedia of Industrial Chemistry, 3rd edition, 3rd volume, page 144, for example "Polymin P", trademark of BASF).
  • polyethyleneimine according to the invention can be carried out in various ways. Doing so the amount to be used is of course dependent on the concentration of the odor-active substances to be absorbed in the medium to be treated. Because of their ease of use, the use of aqueous polyethyleneimine solutions is appropriate. Although the polyethyleneimine concentration in these solutions is not of critical importance (good results are already achieved with polyethyleneimine concentrations in the range of 0.01%), a polyethyleneimine concentration of 0.1 to 10% and preferably 1 to 3% has been found, particularly from an economic point of view. proven.
  • Solutions of polyethyleneimine in water or other solvents and mixtures thereof are suitable for spraying or atomizing and are preferably used in this way.
  • Another preferred embodiment of the invention consists in impregnating materials which come into contact with odor-active substances with polyethyleneimine. So substances, substances, filters or filter masses and objects such as shoe insoles can be impregnated with polyethyleneimine,
  • polyethyleneimine in particular fatty acids, aldehydes and ketones
  • Absorp tion of amines and sulfides less pronounced, so that a longer contact is required for fully satisfactory results.
  • the polyethyleneimine used according to the invention together with other odor absorbents in order to ensure that compounds such as amines and sulfides are also completely absorbed with short contact times.
  • the polyethyleneimine can be used alone or together with other odor absorbents, depending on the application, together with other customary substances.
  • polyethyleneimine to absorb odor-active substances is practically possible wherever odor elimination is desired.
  • Preferred areas of application are cosmetics and body care, technical odor elimination and room air improvement.
  • polyethyleneimine can be used in body deodorants.
  • shoe insoles can be impregnated with polyethyleneimine.
  • polyethyleneimine for odor control in sewage treatment plants, in particular the waste air that accumulates in these.
  • the invention in particular gives the municipalities the possibility of freeing the residents of municipal sewage treatment plants from often very unpleasant odors in a simple and inexpensive manner.
  • Other areas of application that are suitable for odor elimination using polyethyleneimine include stables, animal processing plants, hospitals and chemical companies.
  • polyethyleneimine as an odor absorbent
  • Another focus of the use according to the invention of polyethyleneimine as an odor absorbent is in the field of indoor air improvement. So can in the air duct. Lines, ducts and shafts of air conditioning and air circulation systems are sprayed with polyethyleneimine solutions, which leads to a continuous elimination of unwanted and undesirable odors.
  • filters which are impregnated with polyethyleneimine can be used in the systems mentioned and in exhaust air purification systems. In this way, the required fresh air supply is reduced, which in turn leads to energy savings.
  • the use of polyethyleneimine solutions in the form of sprays to improve the odor in, for example, toilets and kitchens is particularly suitable.
  • the absorption of a number of odor-active substances was investigated with the help of polyethyleneimine.
  • polyethyleneimine For this purpose, about 50 g of gauze were impregnated with 100 ml of a 1.5% aqueous polyethyleneimine solution and then for 24 hours air dried.
  • the gauze impregnated in this way was introduced into a closed system with a volume of approximately 300 ml.
  • the air in the closed system was circulated by an integrated diaphragm pump. In each case 0.01 g of an odor-active substance was introduced into the circuit.
  • the action of the polyethyleneimine can be supported by adding other absorbents such as zinc sulfate, zinc ricinoleate, soda and zinc carbonate.
  • the exiting air mixture (see Example 1) is then free of all odor-active substances used.
  • a typical wording is as follows:
  • porous support materials such as cotton mats, felt mats, paper or plastic mats were treated with a 1.0 to 2.0% aqueous solution of polyethyleneimine and arranged in an air stream.
  • activated carbon was soaked or sprayed with a 1.0 to 2.0% polyethyleneimine solution and placed in a frame in an air stream.
  • a 0.1 to 2.0% aqueous solution of polyethyleneimine was atomized into an air circuit or an air outlet (e.g. air conditioning, Exhaust air) or atomized via clarifiers or introduced into their air suction.
  • Formulations for cosmetic purposes a) deodorant spray
  • composition is filled as a pump spray using a "press pack” system or with propellant.
  • compositions according to a) and b) are suitable as an additive in soap finishing, the amount of the additive preferably being about 1.0 to 2.0%.
  • Composition A was filled using a "press pack” system while Composition B was filled with a blowing agent in a weight ratio of 70:30.
  • polyethyleneimine "Polymin P” and “Polymin SK” (trademark of BASF) were used.
