Definitions

  • the present invention is in the field of cosmetic products and relates to deodorant preparations.
  • the active substances for combating body odors can be divided into several classes: the class of odor maskers includes perfumes that are used to mask or hide body odor.
  • the odor absorbers are special substances that absorb and largely retain odor-forming compounds. Examples of odor absorbers are mixtures of special, odorless fragrances or a complex zinc salt of ricinoleic acid.
  • An important class of functional compounds are the so-called anti-microbial agents.
  • active ingredients are characterized by a selective activity against the bacteria, which release the irritating odorous substances from the odorless sweat.
  • These anti-microbial agents are bacteriostatic, ie they inhibit bacterial growth without killing the bacteria themselves (no bacteriocidal properties).
  • Typical representatives of these active ingredients are chlorhexidine or triclosan.
  • Another class of active ingredients for deodorant production are the so-called enzyme inhibitors. They work by specifically inhibiting enzymes that are responsible for the development of odors. These are above all ester-splitting lipases, so-called esterases.
  • a typical representative of the esterase inhibitors is citric acid triethyl ester.
  • Antioxidants are also used as active ingredients, since it is assumed that the formation of body odor is at least partly due to the oxidation of sweat components by atmospheric oxygen. Another class of active ingredients does not inhibit the decomposition of sweat, but the development of it. Examples of these antiperspirants (synonymously antiperspirants, antiperspirants) are aluminum compounds such as aluminum sulfate or aluminum chlorohydrate. Antiperspirants thus indirectly act as deodorants by reducing sweating.
  • the invention relates to the use of cyclic dicarbonates of the formula (I)
  • R 1 and R 2 independently of one another represent hydrogen, optionally hydroxyl-substituted linear and branched alkyl radicals having 1 to 4 carbon atoms are esterase inhibitors in cosmetic preparations.
  • deodorant preparations which contain cyclic carbonates as esterase inhibitors bring about a significant reduction in odor formation and at the same time have high skin-cosmetic compatibility.
  • Cyclic carbonates are produced by transesterification of dimethyl carbonate or diethyl carbonate with glycerol or vicinal diols, preferably 1,2-dioien.
  • suitable cyclic carbonates are the transesterification products of the lower dialkyl carbonates mentioned with ethylene glycol, 1, 2-pentanediol, 1, 2-hexanediol, 1, 2-octanediol, 1,2-decanediol, 1, 2-dodecanediol and 1, 2- Hexadecanediol.
  • the diols mentioned are generally prepared by opening the corresponding terminal olefin epoxides with water; analog, of course, 1, 2-diols can also serve as starting materials, which are obtained on the basis of internal olefin epoxides.
  • the amount of cyclic carbonates used as esterase inhibitors in cosmetic products is generally from 0.01 to 5% by weight, preferably from 1 to 3% by weight, based on the composition.
  • the present invention includes the discovery that cyclic carbonates can be used in conjunction with other esterase inhibitors. In a preferred embodiment, the cyclic carbonates are used together with trialkyl citrates.
  • Trialkyl citrates such as trimethyl citrate, tripropyl citrate, tributyl citrate and in particular triethyl citrate (Hydagen® CAT, Henkel KGaA, Düsseldorf / FRG) can preferably be used as further esterase inhibitors.
  • esterase inhibitors are dicarboxylic acids and their esters, such as, for example, glutaric acid, glutaric acid monoethyl ester, glutaric acid diethyl ester, adipic acid, adipic acid monoethyl ester, adipic acid diethyl ester, maionic acid and malonic acid diethyl ester, hydroxy acid carbonic acid and their esters, for example citric acid and its carboxylic acid, such as citric acid and its carboxylic acid, such as citric acid and hydroxycarboxylic acid, for example.
  • Zinc glycinate can also be used as an esterase inhibitor.
  • esterase inhibitors Aminobenzoic acid amides and aryl-substituted alkanoic acid derivatives and N-substituted aminomethylene malonic acid derivatives are known as esterase inhibitors. These further esterase inhibitors are usually used in amounts of from 0.01 to 20% by weight, preferably from 1 to 5% by weight. Unless otherwise stated, all weights are based on!
  • the present invention includes the finding that by using cyclic carbonates in combination with other esterase inhibitors, in particular in combination with trialkyl citrates, a synergistic inhibition of the esterases can be achieved.
  • the total amount of esterase inhibitors used is usually 0.02 to 25% by weight, based on the composition.
  • the cyclic carbonates can be used together with further deodorant active ingredients.
  • the use of aluminum chlorohydrates, anti-microbial active substances and antioxidants is particularly preferred.
  • Aluminum chlorohydrates are colorless, hygroscopic crystals that easily melt in the air and are obtained when aqueous aluminum chloride solutions are evaporated. Aluminum chlorohydrate probably works by contracting or sticking the sweat glands through protein precipitation and / or dehumidification [cf. J. Soc. Cosm. Che. 24, 281 (1973)]. For example, an aluminum chlorohydrate that corresponds to the formula [Al2 (OH) 5CI] * 2.5 H2O and whose use is particularly preferred is commercially available under the brand Locron® from Hoechst AG, Frankfurt / FRG [cf. J. Pharm. Pharmacoi. 26, 531 (1975)]. Aluminum chlorohydrates are the invention Preparations are generally added in amounts of 1 to 50% by weight, preferably 10 to 50% by weight.

  • An interesting natural deodorant is the terpene alcohol farnesol (3,7,11 -trimetyl-2,6, 10-dodecatrien-1 -ol), which is present in the linden blossom oil and has a lily of the valley smell.
  • Phenoxyethanol as well as glycerol monolaurate and diglycerol monocaprinate (DMC) have also proven themselves as bacteriostatics.
  • the proportion of the additional germ-inhibiting agents is usually about 0.1 to 2% by weight, based on the solids content of the preparations.
  • the cyclic carbonates can be used as esterase inhibitors in cosmetic preparations which contain chitin derivatives.
