Definitions

  • the invention is the use of polyquaternium-6 polymers as a deodorant active.
  • a cosmetic or dermatological preparation comprising polyquaternium-6 polymers, in combination with nonionic and / or cationic emulsifiers or rheology modifiers or solubilizers.
  • the preparations can be produced, applied and stored in a stable manner.
  • Antiperspirants or deodorants (deodorants) are used to eliminate or prevent body odor that results when the odorless fresh sweat is decomposed by microorganisms.
  • the usual cosmetic deodorants are based on different active principles.
  • deodorant / deodorant products for use in the underarm area are referred to as deodorants or "deodorants”, irrespective of the question as to whether an antiperspirant effect is also present.
  • Antiperspirants are antiperspirants, which, in contrast to the deodorants, should prevent the secretion of sweat at all. In contrast, deodorants generally prevent microbial decomposition of already formed sweat.
  • Sweat odor consists to a large extent of branched-chain fatty acids, which are released by bacterial enzymes from odorless sweat.
  • Classic deodorizing agents counteract this by reducing the growth of bacteria. It is crucial for a deodorizing effect when desodoriende drugs act primarily against the bacteria Staphylococcus epidermidis and Corynebacterium jeikeium.
  • Polyquaternium polymers are INCI nomenclature designations for complex quaternary ammonium polymer compounds. The various representatives of this group are distinguished by numbers. For example, polyquaternium-1, polyquaternium-16 (PQ-16), polyquaternium-42, etc. As quaternary ammonium compounds, polyquaternium polymers have quaternary nitrogens, i. H. all four hydrogen atoms of the ammonium ion are replaced by organic radicals. The compounds are thus cationic, so they have a positive charge.
  • WO 2013052454 A1 lists an overview of known polyquaternium polymers and their trade names.
  • polyquaternium polymers u.a. known Merquat TM 550 polymer, INCI name: Polyquaternium-7.

  • DADMAC diallyldimethylammonium chloride
  • EP 1504744 B1 uses polyquaternium-16 polymers in the field of hair care, in particular in hair sprays.
  • polyquaternium-16 polymers are described in disinfectants, as well as alcoholic solutions. These include, however an alcohol content of at least 50%. Due to the known high cationic charge density of the polymers, the use of a large amount of ethanol is necessary for homogeneous stabilization in the product.
  • EP 1991654 A1 discloses polyquaternium-16 polymers, e.g. available under the name Luviquat FC 905, described in soap bars.
  • EP 200548 A2 describes deodorant preparations comprising antimicrobial agents, such as triclosan or benzalkonium chloride.
  • the formulations further include cationic polymers, especially copolymers of dimethyldiallyammonium chlorides (DMDAAC), such as Merquat S® or Merquat 550® (PQ-7).
  • DMDAAC dimethyldiallyammonium chlorides
  • cationic polymers improve the antimicrobial efficacy of the antimicrobial agents because of their substantivity and film-forming properties. That They ensure that the antimicrobial agents can remain longer at the site of action and thus can only show improved efficacy. An indication that polyquaternium polymers per se have antimicrobial activity and possibly a deodorizing effect is not given.
  • Sweat resistance due to the formation of occlusive films is described in WO 1995/24105 A1 and sweat inhibition due to astringent and liquid-absorbing effects is described in US 4743440 and WO 2003/030853 A2.
  • WO 2009091794 A1 describes preparations which, in addition to antiperspirant active agents, comprise cationic polyquaternium polymers, PQ-6, PQ-7, PQ-10, PQ-11, PQ-22 and in particular PQ-28.
  • EP 1761241 A1 describes antiperspirant active substances based on diallyldimethylammonium chlorides (DADMAC) and diallyethylammonium chlorides (DADEAC), in particular PQ-6 (Merquat® 100, Flocare® C106, Floquat FL45®), Polyquaternium-33 (Floerger FO 4190 VHM®, 4550 BPM®), Polyquaternium-5 (Merquat 5®, Reten®) and Polyquaternium-7 (Merquat 550 L®, Salcare Super 7®, Flocare C107®).
  • DADMAC diallyldimethylammonium chlorides
  • DADEAC diallyethylammonium chlorides
  • JP 2014101356 describes the combination of polyquaternium-10 with antimicrobial substances, such as benzalkonium chloride or isoropylmethylphenol, as a detergent which is said to cause an improvement in body odor, in particular for the elderly.
  • O / W emulsions distinguishable in micro and macroemulsions comprising PQ-6 polymers.

  • Studies on deodorizing efficacy have shown that polyquaternium-6 polymers applied to textiles lead to a significant improvement in odor.
  • preparations according to the invention can also be applied to textiles and can also combat the bad smell there.
  • the polyquaternium-6 polymers show a deodorizing activity. In contrast to the antiperspirants, the deodorants do not actively influence the sweat secretion, but merely control or influence the body odor or underarm odor (odor-improving agent). In this sense, the polyquaternium-6 polymers according to the invention are used as deodorants.
