Abstract
Description
Technical Field
[0001] The present invention relates to a lipstick containing a combination of beeswax (INCI: Cera Alba), rapeseed wax (INCI: Hydrogenated Rapeseed Oil) and sunflower oil obtained from a hybrid of Helianthus annuus (INCI Hybrid Sunflower Oil). Background Art
[0002] For thousands of years, humans have aspired to look beautiful and attractive. Although ideals of beauty have changed over time, the pursuit of a flawless appearance has always been a goal, as a pleasing appearance improves one's self-esteem and attractiveness to peers.
[0003] The concept of decorative cosmetics comes from the Latin word "decoratio", which means to highlight beauty. In most cases, various body parts, especially the face, are highlighted with the help of colorants and color inconsistencies are alleviated.
[0004] In addition to pressed powders and blushes as powder-form cosmetics and stick-form preparations, cream-form preparations such as day creams and emulsion-based cream cosmetics are also used.
[0005] Lipstick belongs to the most commonly used decorative cosmetics. More than 50% of German women use it. In addition to highlighting the color of the lips, it is often used for lip care.
[0006] Lipsticks usually consist of a wax base into which liquid and semisolid oils as well as pigments and fillers are incorporated in high concentrations. They come in the form of solid sticks.
[0007] A disadvantage of the prior art is that a relatively large proportion of waste material occurs in the production of lipsticks. This phenomenon is particularly common in lipsticks made from natural raw materials, i.e. without vaseline, paraffin, mineral oil, silicone oil and silicone wax.
[0008] The production of lipsticks usually takes place in a molding process. Here, a hot liquid formulation is poured into a rod mold, then cooled and solidified. When the hardened rod blank is subsequently removed from the mold and filled into a packaging container, this always results in cracks and splits in the rod body. This production waste increases the effort and costs of lipstick production.
[0009] It is therefore an object of the present invention to develop a lipstick, in particular based on natural raw materials, in the production of which the amount of such waste is reduced.
[0010] In order to be able to assess the risk of fractures and cracks in production during product development, a needle penetration test can be used in the laboratory. In this test, two needles of different thicknesses are pressed into the rod under constant force and the penetration depth is determined. Particularly strong rods are characterized by needles of different thicknesses having the smallest possible difference in penetration depth. The method is described in more detail below.
[0011] In addition to stability against mechanical influences during production, it is also important to maintain the cosmetic properties of the lipstick. In particular, suppleness and the ability to glide when applied to the lips should be maintained. However, a rigid stick that is insensitive to mechanical stress during production has the disadvantage that this suppleness and glide ability are no longer present. Summary of the invention
[0012] The object of the present invention was therefore to develop a lipstick whose organoleptic tactile properties, in particular with regard to softness and glide during application, remain unchanged without high scrap rates during production.
[0013] Surprisingly, these objects are achieved by a lip balm containing a combination consisting of:
[0014] a) Beeswax (INCI: Cera Alba),
[0015] b) Rapeseed wax (INCI: Hydrogenated Rapeseed Oil); and
[0016] c) Sunflower oil obtained from a hybrid of Helianthus annuus (INCI: Hybrid Sunflower Oil, CAS No. 164250-88-8).
[0017] According to the invention, it is advantageous if the lipstick is characterized in that the sunflower oil obtained from a sunflower hybrid (INCI hybrid sunflower oil) has an oleic acid content (C18:1) of 60% to 95% as measured according to IUPAC 2.304. According to the invention, an oleic acid content of 70% to 90% as measured according to IUPAC 2.304 is preferred. In contrast, conventional sunflower oil has an oleic acid content (C18:1) of approximately 14% to 40% as measured according to IUPAC 2.304.
[0018] An advantageous embodiment in the sense of the present invention is also characterized in that the sunflower oil obtained from sunflower hybrids (INCI hybrid sunflower oil) has an acid value measured according to IUPAC 2.201 (m) of at most 0.22 mg KOH / g. It is preferred according to the invention that the acid value measured according to IUPAC 2.201 (m) is at most 0.2 mg KOH / g.
[0019] Furthermore, it is advantageous according to the invention if the sunflower oil obtained from a sunflower hybrid (INCI hybrid sunflower oil) has a peroxide value measured according to AOCS Cd8b-90 (m) of a maximum of 1.1 meq / kg. It is preferred according to the invention if the peroxide value measured according to AOCS Cd8b-90 (m) is a maximum of 1.0 meq / kg.
[0020] An advantageous embodiment according to the invention of the lipstick according to the invention is characterized in that the preparation contains ascorbyl palmitate.
[0021] It is advantageous according to the invention here if the content of ascorbyl palmitate is 0.01 to 0.05% by weight, relative to the total weight of the preparation.
[0022] It is furthermore advantageous according to the invention if the formulation of the lipstick contains lecithin.
[0023] In this context, it is advantageous according to the invention if the lecithin content is 0.05 to 0.1% by weight, relative to the total weight of the preparation.
[0024] An advantageous embodiment of the lipstick according to the invention is characterized in that the preparation contains beeswax (INCI: Cera Alba) in a concentration of 10 to 18% by weight, relative to the total weight of the preparation. Here, a content of 13 to 15% by weight, relative to the total weight of the preparation, is preferred according to the invention.
[0025] According to the invention, it is advantageous if the lipstick formulation contains rapeseed wax (INCI: Hydrogenated Rapeseed Oil) in a concentration of 8 to 16% by weight, relative to the total weight of the formulation. Here, according to the invention, a content of 11 to 13% by weight, relative to the total weight of the formulation, is preferred.
[0026] Furthermore, it is advantageous according to the invention if the lipstick formulation contains sunflower oil obtained from a Helianthus annuus hybrid (INCI Hybrid Sunflower Oil) in a concentration of 60 to 80% by weight, relative to the total weight of the formulation. Here, a content of 65 to 75% by weight, relative to the total weight of the formulation, is preferred according to the invention.
[0027] A further feature of an advantageous embodiment of the invention is that the preparation contains shea butter (Butyrospermum Parkii Butter). In this case, it is preferred according to the invention that the preparation contains shea butter (Butyrospermum Parkii Butter) in a concentration of 1 to 7% by weight relative to the total weight of the preparation.
[0028] It is also advantageous according to the invention if the preparation contains tocopherol. It can be used in a concentration of 0.05 to 0.1% by weight, relative to the total weight of the preparation.
[0029] An advantageous embodiment of the invention according to the invention is also obtained in that the preparation is free of 2-ethylhexyl 2-cyano-3,3-diphenylacrylate (octocrylene), homomanganate salicylate (homosalate), 4-methoxycinnamate (2-ethylhexyl), 3-(4-methylbenzylidene) camphor, 2-hydroxy-4-methoxybenzophenone (oxybenzone), methyl anthranilate (INCI: Methyl Anthranilate) and sulisophenone (INCI: Benzophenone-4), polyethylene glycols, polyethylene glycol ethers and polyethylene glycol esters (so-called PEG derivatives), free of polyacrylates and free of parabens, methylisothiazolinone, chloromethylisothiazolinone and DMDM hydantoin.
[0030] In particular, it is advantageous according to the invention if the lipstick formulation is free of vaseline, paraffin, mineral oil, silicone oil and silicone wax.
[0031] An advantageous lipstick according to the invention is also characterized in that, in a penetration test using an electronic gravimetric penetration tester Petrotest PNR 10, at 20° C. and with a penetration time of 5 seconds, the difference in penetration depth between a normal needle 2.5 g (order number 18-0063 Petrotest Instruments) and a conical needle 2.5 g (order number 18-0081 Petrotest Instruments) is less than 1.8 mm.
[0032] Needle penetration is usually a study of the consistency of highly viscous, deformable materials. Here, a needle-shaped or conical indenter, here 47.5 g (order number 18-0042 PetrotestsInstruments), is placed on the sample surface with the aid of a drop rod (clamping shank and guide shank) and allowed to penetrate into the test material within a specified time under the deadweight of the drop rod and needle. Here, the penetration depth of the indenter is measured in millimeters and is a measure of the plasticity or consistency.
[0033] The investigation was carried out using the Petrotest PNR 10 electronic gravimetric penetrometer. To investigate the lip balm, the test material (lip balm in the packaging) was placed on the test surface. Here, the indenters are two different needles (see above), which are first clamped in the drop rod (see above), then placed on the surface of the lip balm and finally dropped by the trigger. Within the specified time of 5 seconds, the indenters now penetrate into the material of the lip balm by their own weight (drop rod + needle), after which time the penetration depth can be read.
[0034] Furthermore, the lipstick according to the invention may contain typical ingredients for this type of products, such as colorants, fragrances, UV filters and the like.
[0035] Therefore, it is preferred according to the invention that the lipstick preparation contains one or more UV filters selected from the following group of compounds: 2,4,6-tris-[anilino-(p-carbon-2'-ethyl-1'-hexyloxy)]-1,3,5-triazine (INCI: ethylhexyl triazone), 2-ethylhexyl 2-hydroxybenzoate (INCI: ethylhexyl salicylate), 2,4-bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI: bis-ethylhexyloxyphenol methoxyphenyl triazine) and 4-(tert-butyl)-4'-methoxydibenzoylmethane (INCI: butyl methoxydibenzoylmethane). In this context, it is particularly preferred according to the invention to use a combination of 2,4,6-tris-[anilino-(p-carbo-2'-ethyl-1'-hexyloxy)]-1,3,5-triazine (INCI: ethylhexyl triazone) and 4-(tert-butyl)-4'-methoxydibenzoylmethane (INCI: butyl methoxydibenzoylmethane).
[0036] The invention also relates to a method for producing a lipstick according to one of the preceding claims, characterized in that all components are melted with stirring, then poured into a casting mold at a temperature of about 57° C. to 63° C. and finally removed after the casting mold together with the casting has cooled for a defined period of time at 17° C. to 23° C.
