Definitions
- the present invention relates to hydrocarbon mixtures containing 14 C isotopes, their use in cosmetic and / or pharmaceutical preparations, as well as cosmetic and / or pharmaceutical preparations containing hydrocarbon mixtures containing 14 C isotopes.
- Sensory light oil bodies are used by the cosmetic industry in a large number of formulations, in particular for decorative cosmetics or in care formulations so-called “light” components.
- These components may be, for example, volatile cyclic silicones (e.g., cyclopentasiloxane or cyclomethicone) or hydrocarbons from petrochemical processes. Because of their production, the latter substances are predominantly mixtures of linear, cyclic and branched hydrocarbons, the flashpoint of which may well be below 50 ° C. (as in the case of isododecane). Examples and application descriptions of such formulations can be found in standard works such as: Handbook of Cosmetic Science and Technology, A. Barel, M. Paye, H. Maibach, Marcel Dekker Inc. 2001. For toxicological, ecological or safety reasons, however, there will in future be a demand for alternative raw materials for such formulation tasks.
- mineral oil refers to the liquid distillation products obtained from mineral raw materials (petroleum, lignite and hard coal), which essentially consist of mixtures of saturated hydrocarbons having a linear, cyclic and / or branched structure
- mineral raw materials petroleum, lignite and hard coal
- these hydrocarbon mixtures must be extensively cleaned and chemically modified before they meet the requirements for cosmetic raw materials.
- the object of the invention was to find alternative raw materials that are ecologically and toxicologically harmless. It was of particular interest to provide raw materials which can be used directly in cosmetic or pharmaceutical preparations without expensive purification steps. Preferably, these raw materials should be available on the basis of renewable resources. These raw materials should be able to be used directly in typical cosmetic and / or pharmaceutical formulations without application restrictions.
- the raw materials should have improved sensor technology compared to the hydrocarbon mixtures of the prior art, it was also desirable that these raw materials have a better skin compatibility. It was of particular interest to provide raw materials which are comparable with respect to their formulation or sensory use possibilities with silicone oils, in particular with low-viscosity silicone oils, such as eg dimethicones. It was desirable in particular to provide raw materials which are suitable as substitutes for silicone oils. In addition, it has been of interest to provide raw materials which have an improved CO 2 balance over the prior art raw materials.
- a further object was to provide raw materials which allows a stable formulation with AP / Deo ( ⁇ antiperspirant / deodorant) agents.
- Cosmetic preparations of the antiperspirant / deodorant category in particular in so-called “stick formulations", still have the problem of insufficient stability of the cosmetic base, in which case, inter alia, the hardness of the manufactured "stick formulation” is in need of improvement.
- a disadvantage of an existing "stick formulation” is that odor changes occur during storage. [Daher say]
- a further object of the invention was therefore to provide raw materials which make it possible to use antiperspirant or deodorizing preparations, in particular those in stick formulation "stable to provide. These preparations should not show any undesirable odor developments, especially during prolonged storage.
- Another task was to provide raw materials, which give a sensory "light” impression, preferably with the same improved skin compatibility, especially in combination with UV Sunscreen filters and in conjunction with self-tanner.
- new raw materials that allow a sensory beneficial impression in decorative cosmetic formulations.
- good dispersibility of pigments is desirable.
- An object of the invention relates to a hydrocarbon mixture containing 14 C isotopes and wherein the hydrocarbon mixture contains at least 2 mutually different hydrocarbons whose carbon number differs by more than 1.
- the term "2 different hydrocarbons" refers to hydrocarbons having a different C number.
- the mixture contains at least one further hydrocarbon with a C number greater than or equal to n + 2 or less than or equal to n-2 ,
- n is an odd number, in particular 7, 9, 11, 13, 15, 17, 19, 21 and / or 23.
- a preferred embodiment of the invention relates to a hydrocarbon mixture containing 14 C isotopes, wherein the hydrocarbon mixture contains at least 2 mutually different hydrocarbons whose carbon number is about 2 different.
- the hydrocarbon mixture in addition to the hydrocarbon having a C number of n nor at least one hydrocarbon having a C number of n + 2.
- the hydrocarbons in the hydrocarbon mixture differ by a maximum of 10 carbon atoms, preferably by a maximum of 8 carbon atoms, more preferably by a maximum of 6 carbon atoms, preferably by a maximum of 4 carbon atoms.
- the invention further comprises a hydrocarbon mixture containing 14 C isotopes containing a hydrocarbon having a C number of n and at least one further hydrocarbon having a C number of n + 2 and / or n + 4 and / or n + 6 and / or n + 8 and / or n + 10.
- the hydrocarbons are selected from the group of hydrocarbons having 7 to 23 carbon atoms, preferably having 11 to 21 carbon atoms.
- hydrocarbon mixture means mixtures of hydrocarbons which contain up to 10% by weight of substances which do not belong to the hydrocarbons.
- the wt .-% information of the hydrocarbons each refer to the sum of the hydrocarbons present in the mixture.
- the non-hydrocarbons present up to 10% by weight are not taken into account for this calculation.
- the substances which do not belong to the hydrocarbons and which may contain up to 10% by weight, in particular up to 8% by weight, preferably up to 5% by weight, in the hydrocarbon mixture according to the invention are, for example, fatty alcohols , which remain as unreacted starting materials in the hydrocarbon mixture.
- CX hydrocarbon includes hydrocarbons having a C number of X, for example, the term Cl 1 hydrocarbon includes all hydrocarbons having a C number of 1 1.
- total hydrocarbons includes all hydrocarbons in the mixture, regardless of their carbon number.
- isotopes also differ by angular momentum (nuclear spin), magnetic moment and electric quadrupole moment.
- the radioactive carbon isotope 14 C (8 neutrons, 6 protons) is formed from the nitrogen atom, so the mass number remains the same.
- carbon 12 C has 6 neutrons and 6 protons - so it is lighter than 14 C.
- the 14 C generated in the atmosphere combines with existing oxygen to form carbon dioxide.
- the photosynthesis of the plants then causes 14 C to enter the biosphere. Since living organisms constantly exchange carbon with the atmosphere during their metabolism, in living organisms the same distribution ratio of the 3 carbon isotopes 12 C-12, 13 C-12 and 14 C occurs as in the atmosphere: living organisms contain 10 per cent 12 stable 12 C u. 13 C isotopes ca. 1, 2 radioactive 14 C isotopes.
- Fossil fuels such as oil, natural gas or coal, were created over 100 million years ago, ie these fuels no longer contain 14 C isotopes because the original 14 C isotopes have decayed and no new 14 C isotopes have been taken up.
